The TEI was the most critical burn of the flight, as any failure of the SPS to ignite would strand the crew in lunar orbit, with little hope of escape. As with the previous burn, the crew had to perform the maneuver above the far side of the Moon, out of contact with Earth.

text: Goddard is a lunar crater that is located along the eastern limb of the Moon, and so is visible from the edge from Earth. It is best viewed during favorable librations when the orientation of the Moon brings it further into sight. The crater is located in the Mare Marginis, to the northeast of the prominent crater Neper. Ibn Yunus, a crater remnant, is attached to the southeastern rim, and is partly overlaid by Goddard. To the northeast is Al-Biruni.

text: Having a mean density of 3,346.4 kg/m³, the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and core. This structure is believed to have resulted from the fractional crystallization of a magma ocean shortly after its formation about 4.5 billion years ago. The energy required to melt the outer portion of the Moon is commonly attributed to a giant impact event that is postulated to have formed the Earth-Moon system, and the subsequent reaccretion of material in Earth orbit. Crystallization of this magma ocean would have given rise to a mafic mantle and a plagioclase-rich crust.

text: A permanent asymmetric moon dust cloud exists around the Moon, created by small particles from comets. Estimates are 5 tons of comet particles strike the Moon's surface each 24 hours. The particles strike the Moon's surface ejecting moon dust above the Moon. The dust stays above the Moon approximately 10 minutes, taking 5 minutes to rise, and 5 minutes to fall. On average, 120 kilograms of dust are present above the Moon, rising to 100 kilometers above the surface. The dust measurements were made by LADEE's Lunar Dust EXperiment (LDEX), between 20 and 100 kilometers above the surface, during a six-month period. LDEX detected an average of one 0.3 micrometer moon dust particle each minute. Dust particle counts peaked during the Geminid, Quadrantid, Northern Taurid, and Omicron Centaurid meteor showers, when the Earth, and Moon, pass through comet debris. The cloud is asymmetric, more dense near the boundary between the Moon's dayside and nightside.

text: The Soviet Union sent the first spacecraft to the vicinity of the Moon, the robotic vehicle Luna 1, on January 4, 1959.  It passed within  of the Moon's surface, but did not achieve lunar orbit.  Luna 3, launched on October 4, 1959, was the first robotic spacecraft to complete a circumlunar free return trajectory, still not a lunar orbit, but a figure-8 trajectory which swung around the far side of the Moon and returned to the Earth.

text: Safely on the Moon, they explore the lunar surface, reporting back by radio how their view of the Earth looks contrasted against the black lunar sky; one crew member photographs another pretending to hold up the Earth like a modern Atlas. The story takes a serious turn when they calculate the mass needed to lighten their spaceship in the Moon's one-sixth gravity in order to get home safely with their remaining fuel. No matter how much non-critical equipment they remove and leave on the lunar surface, the hard numbers radioed from Earth continue to point to one conclusion: Someone will have to stay behind on the Moon if the other three crew are to return safely to Earth. With time running out for their return launch window, the crew engineers their way home. They first jettison the ship's heavy radio equipment, losing contact with Earth, and finally their sole remaining space suit. An oxygen tank is used as a tethered, suspended weight to pull the space suit outside through the open airlock, which is then remotely closed and resealed. Their critical take-off weight finally achieved, and with all her crew safely aboard, Luna blasts off from the Moon for home.

text: The most obvious effect of tidal forces is to cause two bulges in the Earth's oceans, one on the side facing the Moon and the other on the side opposite. This results in elevated sea levels called ocean tides. As the Earth spins on its axis, one of the ocean bulges (high tide) is held in place "under" the Moon, while another such tide is opposite. As a result, there are two high tides, and two low tides in about 24 hours. Since the Moon is orbiting the Earth in the same direction of the Earth's rotation, the high tides occur about every 12 hours and 25 minutes; the 25 minutes is due to the Moon's time to orbit the Earth. The Sun has the same tidal effect on the Earth, but its forces of attraction are only 40% that of the Moon's; the Sun's and Moon's interplay is responsible for spring and neap tides. If the Earth was a water world (one with no continents) it would produce a tide of only one meter, and that tide would be very predictable, but the ocean tides are greatly modified by other effects: the frictional coupling of water to Earth's rotation through the ocean floors, the inertia of water's movement, ocean basins that grow shallower near land, the sloshing of water between different ocean basins. As a result, the timing of the tides at most points on the Earth is a product of observations that are explained, incidentally, by theory.

text: Armed with the knowledge of shock-metamorphic features, Carlyle S. Beals and colleagues at the Dominion Astrophysical Observatory in Victoria, British Columbia, Canada and Wolf von Engelhardt of the University of Tübingen in Germany began a methodical search for impact craters. By 1970, they had tentatively identified more than 50. Although their work was controversial, the American Apollo Moon landings, which were in progress at the time, provided supportive evidence by recognizing the rate of impact cratering on the Moon. Because the processes of erosion on the Moon are minimal, craters persist almost indefinitely.  Since the Earth could be expected to have roughly the same cratering rate as the Moon, it became clear that the Earth had suffered far more impacts than could be seen by counting evident craters.

text: They photograph the lunar surface as they begin to land on the Moon, but more fuel is wasted when they try to avoid a large, deep canyon on their final landing approach. The spaceship lands out of direct line-of-sight of the Earth, so they are unable to report back via radio. The estimates of their remaining fuel supply indicates they lack enough fuel to return home safely. Admiral Bowles takes the view their safe return is irrelevant. All that matters now is that they claim the Moon in the name of the United States of America and make radio contact with Earth to report this fact. He suggests using their remaining fuel to make a brief flight into direct sight of Earth to report their claim, sacrificing themselves in the process for the greater good. The other crew members, however, prefer to try to return home, if at all possible.

text: While the orbit of a satellite around the Sun was empirically discovered by Kepler and theoretically proven by Newton to be an ellipse, at the time when the United States was interested in going to the Moon, there was no such solution known for the shape of a satellite orbiting regularly around two objects, such as a spacecraft going between the Earth and the Moon.  This is a special case of the infamous Three Body Problem, for which a  general analytical solution is not known because of its complexity of solving the effect of three bodies which all pull on each other while moving, a total of six interactions.  However the case of an Earth-Moon satellite can be simplified to four interactions, because although the three objects gravitationally all pull on each other, the effect of the spacecraft's gravity upon the motion of the vastly more massive Earth and Moon is practically non-existent.  Arenstorf found a stable orbit for a spacecraft orbiting between the Earth and Moon, shaped like an '8' with the Earth or Moon located inside each loop of the '8'.  This orbit is the basis of a path going to the Moon from the Earth, such as the United States Apollo program.  For a permanent presence on the Moon, it would be the path of what Arenstorf calls a 'Space Bus', a ferry which could regularly orbit supplies and people between the Earth and Moon without directly expending fuel.   By staying on the Arenstorf orbit, lunar astronauts automatically return to Earth.  Before leaving NASA at the first Moon Landing, Arenstorf mapped out an emergency rescue orbit, which was used in the Apollo 13 incident, in which a catastrophic malfunction forced aborting the Moon landing, but the astronauts ultimately returned safely to Earth without a major course adjustment.

text: Lunar scientists were particularly interested in rocks that had higher concentrations of samarium, uranium, thorium, potassium and phosphorus. They gave these rocks the acronym KREEP (potassium (atomic symbol K), rare earth elements (REE), and phosphorus (P)). The gamma-ray spectrometer was designed to detect these types of rocks. They had been found at the Apollo 12 and Apollo 14 landing sites but not at the Apollo 11 site, which was about 1,000 km to the east. At the time of the Apollo 15 scientists were interested in whether KREEP rocks were found all over the Moon or just in the region around 12 and 14. It is believed that KREEPs represent the last chemical remnants of that magma ocean after the lunar crust formed. KREEPs floated to the surface because their component elements are "incompatible", that is, they did not incorporate into compact crystal structures. Results from Lunar Prospector's gamma ray spectrometer shows that KREEP-containing rocks are concentrated in the Mare Imbrium rim, the near side maria and highlands near Imbrium and the Mare Ingenii South Pole-Aitken basin and are distributed at a lower level in the highlands. The distribution seen by Lunar Prospector supports the idea that the impact which formed Mare Imbrium excavated KREEP-rich rocks and ejected them over the Moon and the South Pole-Aitken basin impact also exposed KREEP-rich material.

text: Because the gravitational field created by the Moon weakens with distance from the Moon, it exerts a slightly stronger than average force on the side of the Earth facing the Moon, and a slightly weaker force on the opposite side. The Moon thus tends to "stretch" the Earth slightly along the line connecting the two bodies. The solid Earth deforms a bit, but ocean water, being fluid, is free to move much more in response to the tidal force, particularly horizontally.  As the Earth rotates, the magnitude and direction of the tidal force at any particular point on the Earth's surface change constantly; although the ocean never reaches equilibrium—there is never time for the fluid to "catch up" to the state it would eventually reach if the tidal force were constant—the changing tidal force nonetheless causes rhythmic changes in sea surface height.

text: The topography of the Moon has been measured with laser altimetry and stereo image analysis. Its most visible topographic feature is the giant far-side South Pole–Aitken basin, some  in diameter, the largest crater on the Moon and the second-largest confirmed impact crater in the Solar System. At  deep, its floor is the lowest point on the surface of the Moon. The highest elevations of the Moon's surface are located directly to the northeast, and it has been suggested might have been thickened by the oblique formation impact of the South Pole–Aitken basin. Other large impact basins, such as Imbrium, Serenitatis, Crisium, Smythii, and Orientale, also possess regionally low elevations and elevated rims. The far side of the lunar surface is on average about  higher than that of the near side.

text: Interpretation of the origin of the smooth plains is difficult but significant, because it bears directly on the internal constitution and thermal history of Mercury. Like the lunar maria, the smooth plains occur on the floors of large craters and basins, and the broad swath of plains around Caloris finds an analogy with Oceanus Procellarum around Imbrium on the Moon. However, the Caloris plains differ from the maria in having no observed positive-relief volcanic features such as those sparsely scattered on the lunar maria. The absence of sharp albedo differences between the smooth plains and the older terrain (Hapke and others, 1975), compared with the distinct difference in albedo between the lunar maria and highlands, may be more indicative of composition than of origin of the rocks. On the basis of distribution and volume, Strom and others argued that in most areas the smooth plains consist of extensive sheets of basic lava similar to the lunar maria. Schultz (1977), studying modified impact craters, also argued in favor of volcanism. On the other hand, Wilhelms pointed out that the lunar light plains could also serve as an analog of the mercurian smooth plains: Apollo 16 samples indicate that lunar light plains consist of cataclastic breccia and impact melt, interpreted as being emplaced by large impact events (James, 1977). Wilhelms, therefore, proposed that the smooth plains on Mercury may be related to the Caloris impact directly, as breccias and impact melts, rather than as lavas. However, the light plains on the Moon are nowhere so well developed or extensive as the plains around Caloris, and if Wilhelms’ explanation is correct, considerable differences must exist between large impact events on the Moon and Mercury. Most likely, large parts of the smooth plains are of volcanic origin, although in some areas they may be of impact-melt origin.

text: A more ambitious project called the "Aristarchus Campaign" was conducted during the Lunar Eclipse of 15 April 2014. During this event, participants were invited to record a series of 5 digital photographs from moonrise through culmination - the point of greatest altitude.The method took advantage of the fact that the Moon is actually closest to an observer when it is at its highest point in the sky, compared to when it is on the horizon. Although it appears that the Moon is biggest when it is near the horizon, the opposite is true. This phenomena is known as the moon illusion. The reason for the change in distance results from the fact that the distance from the center of the Moon to the center of Earth is nearly constant throughout the night, but an observer on the surface of Earth is actually 1 Earth radius from the center of Earth.  This offset brings them closest to the Moon when it is overhead.

text: The astronauts are left for dead in space, but they fall through a black hole and land in Heaven. Leaving Heaven guided by the Holy Spirit in the form of a dove, they refuel and make it back to the Moon where they encounter some US astronauts. They then use a US space-based surveillance system to find the centre of the water theft conspiracy on Earth. The crew return to Earth and rescue a hostage scientist (Per Jensen's girlfriend) at the installation. They defeat an alien monster with a keg of beer in a manner similar to that in Jaws and escape the installation just in time as it is destroyed by a nuclear bomb, sent from the Moon.

text: Also many moons, even those that do not orbit the Sun directly, often exhibit features in common with true planets. There are 19 moons in the Solar System that have achieved hydrostatic equilibrium and would be considered planets if only the physical parameters are considered.  Both Jupiter's moon Ganymede and Saturn's moon Titan are larger than Mercury, and Titan even has a substantial atmosphere, thicker than the Earth's. Moons such as Io and Triton demonstrate obvious and ongoing geological activity, and Ganymede has a magnetic field. Just as stars in orbit around other stars are still referred to as stars, some astronomers argue that objects in orbit around planets that share all their characteristics could also be called planets. Indeed, Mike Brown makes just such a claim in his dissection of the issue, saying:

text: The band's follow-up album, Interiors, released on June 24, 1997, was much more polished. Tom Moon of Rolling Stone said that "what's most notable about Interiors...is the pure pop focus of these nuanced compositions." The lead single from Interiors, "The Day Brings", features Mike McCready from Pearl Jam on lead guitar. Interiors was met with poor sales, however the band saw its cult audience expand. The album was accompanied by a tour in the United States and Canada that same year, as well as a small tour in Australia and New Zealand in 1998.

This happens when the Moon is near one of the two nodes of its orbit on the ecliptic at the time of the syzygy.  Of course, to produce an eclipse, the Sun must also be near a node at that time: the same node for a solar eclipse, or the opposite node for a lunar eclipse.

text: A colony in lunar orbit would avoid the extreme temperature swings of the Moon's surface. Since the orbital period in low-lunar orbit is only about two hours, heat would only radiate away from the colony for a short period of time. At the Lagrangian points one and two, the thermal environment would be even more stable as the Sun would be almost continuously visible. This increased solar duration would allow for an almost constant supply of power. Additionally, the colony could be made to spin as has been examined with designs similar to the O'Neill cylinder so as to provide Earth-like gravity. Various lunar orbits are possible such as a Lissajous orbit or a halo orbit. Due to the Moon's lumpy gravity, there exist only a small number of possible orbital inclinations for low lunar orbits. A satellite in such a frozen orbit could be at an inclination of 27°, 50°, 76°, or 86°.

text: Therefore, at most new moons the Earth passes too far north or south of the lunar shadow, and at most full moons the Moon misses the shadow of the Earth.  Also, at most solar eclipses the apparent angular diameter of the Moon is insufficient to fully obscure the solar disc, unless the Moon is near its perigee, i.e. closer to the Earth and apparently larger than average. In any case, the alignment must be close to perfect to cause an eclipse.

text: Amundsen is a large lunar impact crater located near the south pole of the Moon, named after the Norwegian explorer Roald Amundsen. It lies along the southern lunar limb, and so is viewed from the side by an observer on the Earth. To the northwest is the crater Scott, a formation of similar dimensions that is named for another Antarctic explorer. Nobile is attached to the western rim.

text: Anderson speculates that the true intention of the ICBM warning devices is to monitor the aliens, and that the devices are the source of the interference, only to discover something has destroyed them when they attempt to switch them off. Walker shows signs of a developing infection and he becomes increasingly paranoid. The mission cameras capture the rock samples moving around in the interior of Liberty, revealing that the aliens are camouflaged as moon rocks. Increasingly delusional, Walker attempts to destroy the cameras within Liberty, but he accidentally damages the system controls, causing Liberty to depressurize. Realizing the Soviet LK is their only source of oxygen, the pair travel towards the LK lander in their lunar rover. Walker causes the vehicle to crash as he runs away, believing he should not leave the moon because of the risk of spreading the infection to Earth.

text: The moon's orbit isn't in the same plane as the Earth's orbit around the sun, but crosses it in two places. The moon crosses the ecliptic plane twice a month, once when it goes up above the plane, and again 15 or so days later when it goes back down below the ecliptic. These two locations are the ascending and descending lunar nodes. Solar and lunar eclipses will occur only when the moon is positioned near one of these nodes, because at other times the moon is either too high or too low for an eclipse to be noticed from earth. Some astronomical clocks keep track of the position of the lunar nodes with a long pointer that crosses the dial. This so-called dragon hand makes one complete rotation around the ecliptic dial every 19 years. When the dragon hand and the new moon coincide, the moon is on the same plane as the earth and sun, and so there is every chance that an eclipse will be visible from somewhere on earth.

text: Jonson opens his masque with a conversation among two heralds, a printer, a chronicler, and a factor (a kind of columnist or correspondent). All are in some sense in the news business, though their approaches differ; the traditional heralds are startled by the capitalist assumptions of the printer, who asks them the cost-price of their news. The characters discuss a number of contemporary issues, culminating in the news from the Moon — which allows for satire on a range of subjects. The Moon is described as "an earth inhabited...With navigable seas and rivers...forests, parks, coney-ground, meadow-pasture, what not?" With all the similarities between Earth and Moon, though, there are differences; the Moon's denizens have no spoken language, rather communicating by signs — which renders all the lawyers mute. They also have no tailors; as a result, the lunar "self-lovers" have all died.

text: The gravitational attraction between Earth and the Moon causes tides on Earth. The same effect on the Moon has led to its tidal locking: its rotation period is the same as the time it takes to orbit Earth. As a result, it always presents the same face to the planet. As the Moon orbits Earth, different parts of its face are illuminated by the Sun, leading to the lunar phases; the dark part of the face is separated from the light part by the solar terminator.

Panthea then claims, "A mighty Power, which is as darkness,/ Is rising out of Earth, and from the sky/ Is showered like night, and from within the air/ Bursts, like eclipse which has been gathered up/ Into the pores of sunlight".

text: Indirect evidence for the giant impact scenario comes from rocks collected during the Apollo Moon landings, which show oxygen isotope ratios nearly identical to those of Earth. The highly anorthositic composition of the lunar crust, as well as the existence of KREEP-rich samples, suggest that a large portion of the Moon once was molten; and a giant impact scenario could easily have supplied the energy needed to form such a magma ocean. Several lines of evidence show that if the Moon has an iron-rich core, it must be a small one. In particular, the mean density, moment of inertia, rotational signature, and magnetic induction response of the Moon all suggest that the radius of its core is less than about 25% the radius of the Moon, in contrast to about 50% for most of the other terrestrial bodies. Appropriate impact conditions satisfying the angular momentum constraints of the Earth–Moon system yield a Moon formed mostly from the mantles of the Earth and the impactor, while the core of the impactor accretes to the Earth. It is noteworthy that the Earth has the highest density of all the planets in the Solar system ; the absorption of the core of the impactor body renders this observation explicable, given the proposed properties of the early Earth and Theia.

text: The notional tidal bulges are carried ahead of the Earth–Moon axis by the continents as a result of Earth's rotation. The eccentric mass of each bulge exerts a small amount of gravitational attraction on the Moon, with the bulge on the side of Earth closest to the Moon pulling in a direction slightly forward along the Moon's orbit (because Earth's rotation has carried the bulge forward). The bulge on the side furthest from the Moon has the opposite effect, but because the gravitational attraction varies inversely with the square of distance, the effect is stronger for the near-side bulge. As a result, some of Earth's angular (or rotational) momentum is gradually being transferred to the rotation of the Earth–Moon pair around their mutual centre of mass, called the barycentre. This slightly faster rotation causes the Earth–Moon distance to increase at approximately 38 millimetres per year. Conservation of angular momentum means that Earth's axial rotation is gradually slowing, and because of this its day lengthens by approximately 23 microseconds every year (excluding glacial rebound). Both figures are valid only for the current configuration of the continents. Tidal rhythmites from 620 million years ago show that, over hundreds of millions of years, the Moon receded at an average rate of  per year and the day lengthened at an average rate of 12 microseconds per year, both about half of their current values. See tidal acceleration for a more detailed description and references.

text: Like all lunar maria, Oceanus Procellarum was formed by ancient basaltic flood volcanic eruptions that covered the region in a thick, nearly flat layer of solidified magma. Unlike the other lunar maria, however, Oceanus Procellarum may or may not be contained within a single well-defined impact basin. Around its edges lie many minor bays and seas, including Mare Nubium and Mare Humorum to the south. To the northeast, Oceanus Procellarum is separated from Mare Imbrium by the Carpathian Mountains. On its north-west edge lies the 32 km wide Aristarchus ray crater, which is considered as the brightest feature on the Near side of the Moon. Also, the more-prominent ray-crater Copernicus lies within the eastern edge of the mare, distinctly with its bright ray materials sprawling over the darker material. On the northern edge of Oceanus Procellarum lies Sinus Roris.

text: The Arkansas Apollo 17 lunar sample display commemorative style plaque, measuring 10 by 14 inches, consists of one "moon rock" particle specimen that was cut from lunar basalt 70017 and an Arkansas state flag. The basalt 70017 was collected by Apollo 17 astronaut Harrison Schmitt on the moon in 1972. Once lunar basalt 70017 was brought back to earth from the moon, the basalt moon rock was cut up into small fragments of approximately 1 gram. The piece of "moon rock" given to Arkansas weighed about 1.142-gram (0.0025 lb). The specimen was encased in a plastic ball that was mounted on the wooden plaque along with the Arkansas state flag which had been taken to the moon and back by the crew of Apollo 17. The plaque was then distributed in 1973 by President Richard Nixon to the state of Arkansas as he did that year to the other 49 states (the same as for the Apollo 11 plaque gifts). This was done as a goodwill gesture to promote peace and harmony.

text: A related problem is that of centrifugal forces for the Earth-Moon-Sun system, where three rotations appear: the daily rotation of the Earth about its axis, the lunar-month rotation of the Earth-Moon system about their center of mass, and the annual revolution of the Earth-Moon system about the Sun. These three motions influence the tides.

text: The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—Europa and Enceladus respectively, although if life exists in either place, it would probably be confined to subsurface habitats. Historically, life on Earth was thought to be strictly a surface phenomenon, but recent studies have shown that up to half of Earth's biomass could live below the surface. Europa and Enceladus exist outside the circumstellar habitable zone which has historically defined the limits of life within the Solar System as the zone in which water can exist as liquid at the surface. In the Solar System's habitable zone there are only three natural satellites—the Moon, and Mars's moons Phobos and Deimos (although some estimates show Mars and its moons to be slightly outside the habitable zone) —none of which sustain an atmosphere or water in liquid form. Tidal forces are likely to play as significant a role providing heat as stellar radiation in the potential habitability of natural satellites.

text: Humboldt is a large lunar crater that is located near the eastern limb of the Moon. Due to foreshortening this formation has an extremely oblong appearance. The actual shape of the crater is an irregular circle, with a significant indentation along the southeastern rim where the prominent crater Barnard intrudes. To the north-northwest of Humboldt is the large crater Hecataeus. Phillips is attached to the western rim.  The rim of Humboldt is low, worn, and irregular in outline.  The central peak forms a range on the crater floor. The floor surface contains a network of rilles forming a pattern of radial spokes and concentric arcs. There are also some dark patches located near the walls to the northeast, northwest, and southeast. There is a chain of craters leading from the northwest crater rim to a distance almost as long as the crater is wide. This formation is designated Catena Humboldt.  Due to its location near the lunar limb, little detail was known about this crater until it was photographed by orbiting spacecraft (mainly Lunar Orbiter 4).

text: A straight line connecting the pericenter and apocenter is the line of apsides. This is the major axis of the ellipse, its greatest diameter.  For a two-body system the center of mass of the system lies on this line at one of the two foci of the ellipse. When one body is sufficiently larger than the other it may be taken to be at this focus.  However whether or not this is the case, both bodies are in similar elliptical orbits each having one focus at the system's center of mass, with their respective lines of apsides being of length inversely proportional to their masses.  Historically, in geocentric systems, apsides were measured from the center of the Earth. However, in the case of the Moon, the center of mass of the Earth–Moon system, or Earth–Moon barycenter, as the common focus of both the Moon's and Earth's orbits about each other, is about 74% of the way from Earth's center to its surface.

text: Brown's objective had been to produce an accurate ephemeris of the Moon, based purely on gravitational theory. For the 'main problem' of the Earth-Moon-Sun system, he calculated terms in longitude and latitude down to an uncertainty of 0.001 arcseconds. He also included perturbations due to the other planets (principally Jupiter and Venus) and also accounted for the more difficult problem of the non-spherical nature of the Earth and Moon.

text: The great depth of this mare beneath the nearby highlands probably explains why mare units are so rare on the lunar farside. Very few basins on the farside were deep enough to allow mare volcanism. Thus, while large impact basins are found on both the nearside and farside, large maria are mostly found on the nearside. Mare lavas apparently could reach the surface more often and more easily there. The basin material is of the Nectarian epoch, while the mare material is of the Upper Imbrian epoch. Following the SELENE mission, scientists proposed that volcanism in Mare Moscoviense was active for at least ~1.5 Ga following the formation of the Moscoviense basin, but the formation of the mare as the result of a meteorite cluster impact, rather than from volcanism, has also been proposed based on the energy required to melt the lava in Mare Moscoviense.

text: A subject of on-going research is the formation of the Moon, some 4.53 billion years ago. A working hypothesis is that it was formed by accretion from material loosed from Earth after a Mars-sized object, named Theia, impacted Earth. In this scenario, the mass of Theia was approximately 10% of that of Earth, it impacted Earth with a glancing blow, and some of its mass merged with Earth. Between approximately 4.1 and , numerous asteroid impacts during the Late Heavy Bombardment caused significant changes to the greater surface environment of the Moon, and by inference, to that of Earth.

Kranz's team was on duty when part of the Apollo 13 Service Module exploded and they dealt with the initial hours of the unfolding accident. His "White Team", dubbed the "Tiger Team" by the press, set the constraints for the consumption of spacecraft consumables (oxygen, electricity, and water) and controlled the three course-correction burns during the trans-Earth trajectory, as well as the power-up procedures that allowed the astronauts to land safely back on Earth in the command module.

text: Company President/CEO Alan Stern has announced in briefing papers that the company had commenced feasibility studies into commercial missions to the Moon from early 2010 and formed the company in the third quarter of that year.  Since then, the company has been building its business models and soliciting investment.   Currently, the company has budgeted between $7 and $8 billion to achieve their objective, followed by around $1.5 billion fee per each "two-human lunar surface mission". Golden Spike will follow a model like that of the Russian spaceflight industry in the 1980s and '90s. The company said it can cut costs by partnering with other aerospace companies and using existing rockets or rockets already in development, needing to only build a lunar lander and a specialized spacesuit for astronauts for the Moon. Stern says they expect to sign up as many as 15 to 20 countries or foreign space agencies as well as companies and individuals who want to explore the Moon for science or adventure.  They have identified a mission profile, including various launch options as well as trajectory and spacecraft for landing on the Moon. It involves two sets of two launches from Earth to Earth orbit: one set for the lander and the propulsion unit to send it to Moon orbit, and the other set for the crew vehicle and the propulsion unit to send it to Moon orbit. The two propusion units are disposed of. In Moon orbit the lander and the crew vehicle have a rendez-vous, and the crew move to the lander. They land and return to the crew vehicle, and return to Earth in the crew vehicle.

text: Chalchiuitlicue's name literally means "Jade her skirt", but is usually translated as "she of the jade skirt". She was also known as Matlalcueitl "Owner of the green skirt".  This goddess was the wife (in some myths, sister) of the rain god, Tlaloc. Like other water deities, she was often associated with serpents. She was the mother of Tecciztecatl, an Aztec moon god. He was called "he who comes from the land of the sea-slug shell" because of the similarity between the moon and the slug. Tecciztecatl was portrayed as an old man who carries a large white seashell on his back.Most legends of Chalchiuhtlicue say that she was married to the god of rain, Tlaloc. In some myths she was his sister. Chalchiuhtlicue helped Tlaloc rule the kingdom of Tlalocan. It is believed that Tlaloc was one of the first 'abuser' gods and because of this Chalchiuhtlicue retaliated by releasing 52 years of rain, causing a giant flood which caused the fourth world to be destroyed. She built a bridge linking heaven and earth and those who were in Chalchiuhtlicue's good graces were allowed to traverse it. The other residents of the earth were turned into fish so they wouldn't drown. Chalchiuhtlicue used the flood as an act of purification of human kind. Because of this flood we are believed to live in the Fifth World. In some myths, Chalchiuhtlicue was wife of Xiuhtecuhtli, senior deity of the Aztec pantheon. According to Aztec legend, Chalchiuhtlicue at one point devoured the sun and moon.

text: The rocks collected from the Moon are extremely old compared to rocks found on Earth, as measured by radiometric dating techniques. They range in age from about 3.2 billion years for the basaltic samples derived from the lunar maria, to about 4.6 billion years for samples derived from the highlands crust. As such, they represent samples from a very early period in the development of the Solar System, that are largely absent on Earth. One important rock found during the Apollo Program is dubbed the Genesis Rock, retrieved by astronauts David Scott and James Irwin during the Apollo 15 mission. This anorthosite rock is composed almost exclusively of the calcium-rich feldspar mineral anorthite, and is believed to be representative of the highland crust. A geochemical component called KREEP was discovered by Apollo 12, which has no known terrestrial counterpart. KREEP and the anorthositic samples have been used to infer that the outer portion of the Moon was once completely molten (see lunar magma ocean).

text: It is a narrow path for the moon to pass within the penumbra and outside the umbra. It can happen on the Earth's northern or southern penumbral edges. In addition, the size of the penumbra is sometimes too small where the moon enters it to contain the moon. The width of the Earth's penumbra is determined by the sun's angular diameter at the time of the eclipse, and the moon's angular diameter is larger than the sun over part of its elliptical orbit, depending on whether the eclipse occurs at its nearest (perigee) or farthest point (apogee) in its orbit around the earth.  The majority of the time, the size of the moon and the size of the Earth's penumbra where the moon crosses it mean that most eclipses will not be total penumbral in nature.

text: The Moon has a stabilizing effect on Earth's obliquity. Frequency map analysis conducted in 1993 suggested that, in the absence of the Moon, the obliquity can change rapidly due to orbital resonances and chaotic behavior of the Solar System, reaching as high as 90° in as little as a few million years (also see Orbit of the Moon).However, more recent numerical simulations made in 2011 indicated that even in the absence of the Moon, Earth's obliquity might not be quite so unstable; varying only by about 20–25°.The Moon's stabilizing effect will continue for less than 2 billion years. If the Moon continues to recede from Earth due to tidal acceleration, resonances may occur which will cause large oscillations of the obliquity.

text: In the future, a near feudal colony has risen up around the industrialisation of the Moon, and though technology keeps the deadly natural environment at bay, the four basic essentials of life—air, water, carbon and data—come at a price. Tiny "chibs" placed in the eye to meter usage of these Four Elementals serve as a constant reminder of this. Everyone also has a "familiar": a personalized, holographic avatar that hovers over one shoulder and serves as an interface with the Moon's network, other familiars and even one's physical surroundings. The Moon is controlled by five families, dubbed the Five Dragons: the Australian Mackenzies dominate mineral extraction, the Asamoahs of Ghana control a vast underground agricultural industry, the Russian Vorontsovs run the transportation systems, the Suns of China are masters of technology and the upstart Brazilian Cortas mine helium-3 to power Earth's fusion reactors. These families, and all citizens of the Moon, operate under contracts granted by the Lunar Development Corporation (LDC), the Moon's governing body. The Mackenzies and the Cortas—the oldest and the newest lunar families, respectively—are bitter rivals, and as the novel begins, the long-simmering animosity between them seems reignited.

text: These craters appear in a continuum of diameters across the surface of the Moon, ranging in size from tiny pits to the immense South Pole–Aitken Basin with a diameter of nearly 2,500 km and a depth of 13 km. In a very general sense, the lunar history of impact cratering follows a trend of decreasing crater size with time. In particular, the largest impact basins were formed during the early periods, and these were successively overlaid by smaller craters. The size frequency distribution (SFD) of crater diameters on a given surface (that is, the number of craters as a function of diameter) approximately follows a power law with increasing number of craters with decreasing crater size. The vertical position of this curve can be used to estimate the age of the surface.

text: The Moon and Earth orbit a common barycenter every 27.32 days relative to the background stars. When combined with the Earth–Moon system's common orbit around the Sun, the period of the synodic month, from new moon to new moon, is 29.53 days. Viewed from the celestial north pole, the motion of Earth, the Moon, and their axial rotations are all counterclockwise. Viewed from a vantage point above the north poles of both the Sun and Earth, Earth orbits in a counterclockwise direction about the Sun. The orbital and axial planes are not precisely aligned: Earth's axis is tilted some 23.44 degrees from the perpendicular to the Earth–Sun plane (the ecliptic), and the Earth–Moon plane is tilted up to ±5.1 degrees against the Earth–Sun plane. Without this tilt, there would be an eclipse every two weeks, alternating between lunar eclipses and solar eclipses.

text: While tidal forces from the primary are common on satellites, most satellite systems remain stable.  Perturbation between satellites can occur, particularly in the early formation, as the gravity of satellites affect each other, and can result in ejection from the system or collisions between satellites or with the primary.  Simulations show that such interactions cause the orbits of the inner moons of the Uranus system to be chaotic and possibly unstable.  Some of Io's active can be explained by perturbation from Europa's gravity as their orbits resonate.Perturbation has been suggested as a reason that Neptune does not follow the 10,000:1 ratio of mass between the parent planet and collective moons as seen in all other known giant planets. One theory of the Earth-Moon system suggest that a second companion which formed at the same time as the Moon, was perturbed by the Moon early in the system's history, causing it to impact with the Moon.

text: The saros, a period of 6585.3211 days (14 common years + 4 leap years + 11.321 days, or 13 common years + 5 leap years + 10.321 days), is useful for predicting the times at which nearly identical eclipses will occur. Three periodicities related to lunar orbit, the synodic month, the draconic month, and the anomalistic month coincide almost perfectly each saros cycle. For an eclipse to occur, either the Moon must be located between the Earth and Sun (for a solar eclipse) or the Earth must be located between the Sun and Moon (for a lunar eclipse). This can happen only when the Moon is new or full, respectively, and repeat occurrences of these lunar phases result from solar and lunar orbits producing the Moon's synodic period of 29.53059 days. During most full and new moons, however, the shadow of the Earth or Moon falls to the north or south of the other body. Eclipses occur when the three bodies form a nearly straight line.  Because the plane of the lunar orbit is inclined to that of the earth, this condition occurs only when a full or new Moon is near or in the ecliptic plane, that is when the moon is at one of the two nodes (the ascending or descending node). The period of time for two successive lunar passes through the ecliptic plane (returning to the same node) is termed the draconic month, a 27.21222 day period.  The three-dimensional geometry of an eclipse, when the new or full moon is near one of the nodes, occurs every 5 or 6 months when the Sun is in conjunction or opposition to the Moon and coincidentally also near a node of the Moon's orbit at that time, or twice per eclipse year. Two Saros eclipses have the same appearance and duration due to the distance between the Earth and Moon being nearly the same for each event because the Saros eclipse cycle is also an integer of the anomalistic month, the period of the eccentricity of lunar orbit, 27.5545 days.

text: An eclipse involving the Sun, Earth, and Moon can occur only when they are nearly in a straight line, allowing one to be hidden behind another, viewed from the third. Because the orbital plane of the Moon is tilted with respect to the orbital plane of the Earth (the ecliptic), eclipses can occur only when the Moon is close to the intersection of these two planes (the nodes). The Sun, Earth and nodes are aligned twice a year (during an eclipse season), and eclipses can occur during a period of about two months around these times. There can be from four to seven eclipses in a calendar year, which repeat according to various eclipse cycles, such as a saros.

text: The newly formed Moon orbited at about one-tenth the distance that it does today, and spiraled outward because of tidal friction transferring angular momentum from the rotations of both bodies to the Moon's orbital motion. Along the way, the Moon's rotation became tidally locked to Earth, so that one side of the Moon continually faces toward Earth. Also, the Moon would have collided with and incorporated any small pre-existing satellites of Earth, which would have shared the Earth's composition, including isotopic abundances. The geology of the Moon has since been more independent of the Earth. Although this hypothesis explains many aspects of the Earth–Moon system, there are still a few unresolved problems, such as the Moon's volatile elements not being as depleted as expected from such an energetic impact.

text: While scientific experiments performed by Clementine and Lunar Prospector could indicate the presence of water in the polar craters, the current evidence is far from definitive. There are doubts among scientists as to whether or not the hydrogen is in the form of ice, as well as to the concentration of this "ore" with depth below the surface. Resolution of this issue will require future missions to the Moon. The presence of water suggests that the crater floor could potentially be "mined" for deposits of hydrogen in water form, a commodity that is expensive to deliver directly from the Earth.

text: Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a mass, largely under the force of gravity, but frequently affected by water and water content as in submarine environments and mudflows. Types of mass wasting include creep, slides, flows, topples, and falls, each with its own characteristic features, and taking place over timescales from seconds to years. Mass wasting occurs on both terrestrial and submarine slopes, and has been observed on Earth, Mars, Venus, and Jupiter's moon Io.

text: The Lunar landscape exterior was constructed by Jack Poplin and his team on Soundstage #2 at KTTV and the moon backdrops were from M.G.M. The jagged mountains and rock columns were placed so as to hide the gaps in these backdrops. The moon surface itself was a four inch deep layer of sand that had been dyed different colours to give the moonscape different gradations of tone when filmed in black and white. Paintings by astronomical artist Chesley Bonestell were used as background plates for sequences of the two Moonstones moving over the lunar surface.

text: The slathem are fish-like humanoids who exist equally well both in and out of the water. The slathem have not been too terribly affected by the lunar rain. Certain of their towns and cities are underwater for part of the year, because of the immense seasonal tides characteristic of Highpoint.  The winter/summer seasons result in more polar ice cap melting/freezing than on earth, so the Highpoint seasons are labeled Highwater and Lowwater.  Increased tidal effects due to the moon only amplify this problem.

text: The Principia deals primarily with massive bodies in motion, initially under a variety of conditions and hypothetical laws of force in both non-resisting and resisting media, thus offering criteria to decide, by observations, which laws of force are operating in phenomena that may be observed. It attempts to cover hypothetical or possible motions both of celestial bodies and of terrestrial projectiles. It explores difficult problems of motions perturbed by multiple attractive forces. Its third and final book deals with the interpretation of observations about the movements of planets and their satellites. It shows how astronomical observations prove the inverse square law of gravitation (to an accuracy that was high by the standards of Newton's time); offers estimates of relative masses for the known giant planets and for the Earth and the Sun; defines the very slow motion of the Sun relative to the solar-system barycenter; shows how the theory of gravity can account for irregularities in the motion of the Moon; identifies the oblateness of the figure of the Earth; accounts approximately for marine tides including phenomena of spring and neap tides by the perturbing (and varying) gravitational attractions of the Sun and Moon on the Earth's waters; explains the precession of the equinoxes as an effect of the gravitational attraction of the Moon on the Earth's equatorial bulge; and gives theoretical basis for numerous phenomena about comets and their elongated, near-parabolic orbits.

text: On December 24, 1968, the crew of Apollo 8, Frank Borman, James Lovell and William Anders, became the first human beings to enter lunar orbit and see the far side of the Moon in person. Humans first landed on the Moon on July 20, 1969. The first human to walk on the lunar surface was Neil Armstrong, commander of the U.S. mission Apollo 11. The first robot lunar rover to land on the Moon was the Soviet vessel Lunokhod 1 on November 17, 1970 as part of the Lunokhod program. To date, the last human to stand on the Moon was Eugene Cernan, who as part of the mission Apollo 17, walked on the Moon in December 1972. See also: A full list of lunar Apollo astronauts.

text: Selenographic coordinatesare used to refer to locations on the surface of Earth's moon. Any position on the lunar surface can be referenced by specifying two numerical values, which are comparable to the latitude and longitude of Earth. The longitude gives the position east or west of the Moon's prime meridian, which is the line  passing from the lunar north pole through the point on the lunar surface directly facing Earth to the lunar south pole.  (See also Earth's prime meridian.)  This can be thought of as the midpoint of the visible Moon as seen from the Earth. The latitude gives the position north or south of the lunar equator. Both of these coordinates are given in degrees.

text: There are two reasons why the north pole and south pole of the Moon might be attractive locations for a human colony. First, there is evidence that water may be present in some continuously shaded areas near the poles. Second, the Moon's axis of rotation is sufficiently close to being perpendicular to the ecliptic plane that the radius of the Moon's polar circles is less than 50 km. Power collection stations could therefore be plausibly located so that at least one is exposed to sunlight at all times, thus making it possible to power polar colonies almost exclusively with solar energy. Solar power would be unavailable only during a lunar eclipse, but these events are relatively brief and absolutely predictable. Any such colony would therefore require a reserve energy supply that could temporarily sustain a colony during lunar eclipses or in the event of any incident or malfunction affecting solar power collection. Hydrogen fuel cells would be ideal for this purpose, since the hydrogen needed could be sourced locally using the Moon's polar water and surplus solar power. Moreover, due to the Moon's uneven surface some sites have nearly continuous sunlight. For example, Malapert mountain, located near the Shackleton crater at the Lunar south pole, offers several advantages as a site:

text: Partial melting within the mantle of the Moon gave rise to the eruption of mare basalts on the lunar surface. Analyses of these basalts indicate that the mantle is composed predominantly of the minerals olivine, orthopyroxene and clinopyroxene, and that the lunar mantle is more iron rich than that of the Earth. Some lunar basalts contain high abundances of titanium (present in the mineral ilmenite), suggesting that the mantle is highly heterogeneous in composition. Moonquakes have been found to occur deep within the mantle of the Moon about 1,000 km below the surface. These occur with monthly periodicities and are related to tidal stresses caused by the eccentric orbit of the Moon about the Earth. A few shallow moonquakes with hypocenters located about 100 km below the surface have also been detected, but these occur more infrequently and appear to be unrelated to the lunar tides.

text: The idea that the Moon was not perfectly smooth can be traced as far back as approximately 450 BC, when Democritus believed that there were "lofty mountains and hollow valleys" on the Moon. However, it was not until the end of the 15th century when serious study of selenography began. Around 1603, William Gilbert compiled the first lunar drawing based on naked-eye observations. Others soon followed, and when the telescope made its appearance, drawings were begun that at first were not very accurate, but soon became better as optics improved. In the early 18th century, the librations of the Moon were measured, showing that more than 50 percent of the lunar surface was visible to observers. In 1750, Johann Meyer produced the first reliable set of lunar coordinates that would enable astronomers to locate features on the Moon.

text: The Moon's orbit around the Earth is inclined at an angle of just over 5 degrees to the plane of the Earth's orbit around the Sun (the ecliptic). Because of this, at the time of a new moon, the Moon will usually pass to the north or south of the Sun. A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic.

text: Regnault is a lunar impact crater that is located close to the northwest limb of the Moon. It lies across the western rim of the walled plain Volta, with the slightly smaller crater Stokes attached to the southern outer rim. Due to its location, Regnault is not favorably placed for viewing from the Earth. It is seen at a very oblique angle, limiting the detail that can be viewed. The visibility of this crater is also affected by libration of the Moon.

text: The eccentricity of their orbits causes regular flexing of the three moons' shapes, with Jupiter's gravity stretching them out as they approach it and allowing them to spring back to more spherical shapes as they swing away. This tidal flexing heats the moons' interiors by friction. This is seen most dramatically in the extraordinary volcanic activity of innermost Io (which is subject to the strongest tidal forces), and to a lesser degree in the geological youth of Europa's surface (indicating recent resurfacing of the moon's exterior).

text: A partial lunar eclipse occurs when only a portion of the moon enters the umbra. When the moon travels completely into the Earth's umbra, one observes a total lunar eclipse. The moon's speed through the shadow is about one kilometer per second (2,300 mph), and totality may last up to nearly 107 minutes. Nevertheless, the total time between the moon's first and last contact with the shadow is much longer and could last up to four hours. The relative distance of the moon from the Earth at the time of an eclipse can affect the eclipse's duration. In particular, when the moon is near its apogee, the farthest point from the Earth in its orbit, its orbital speed is the slowest. The diameter of the umbra does not decrease appreciably within the changes in the orbital distance of the moon. Thus, a totally eclipsed moon occurring near apogee will lengthen the duration of totality.

text: Lunar orbiters have to remain properly oriented with respect to the Earth, Moon and Sun. All onboard detectors must be kept facing the lunar surface in order to complete their scientific missions, communication antennas have to face the Earth in order to receive commands and transfer scientific data, and solar panels must be oriented toward the Sun in order to acquire power. During lunar orbit, the Earth, the Moon and the Sun also move, so attitude control is a complex three-vector control process. The Chang'e satellites need to adjust their attitude very carefully to maintain an optimal angle towards all three bodies.

text: Mission directors Roland Luettgens and Giovanni Gravili worked closely with the team to turn the filming opportunities into precise technical notes which translated Chris's camera directions into instructions for the crew. After a brief test shoot in November 2010, conducted by NASA's Expedition 25 astronaut Doug Wheelock, European Space Agency astronaut Paolo Nespoli filmed most of the footage for the project in early January 2011. This new footage showed the Earth as Gagarin would have seen it almost exactly fifty years before. The film does include views of the moon, though. When Gagarin flew into the nightside of the Earth on 12 April 1961, there was a crescent moon and, according to his autobiography, Road to the Stars, Gagarin tried looking for the moon out of curiosity, to see what it looked like from space. Unfortunately, it was not in his field of view. The filmmakers added the moon into the scene as a tribute.

text: Tidal flow occurs due to the moving mass of water with speed and direction as caused by the gravitational forces of the sun and the moon, and centrifugal and inertial forces on the Earth's waters. Due to its proximity to the earth, the moon exerts roughly twice the tide raising force of the sun. The gravitational forces of the sun and moon and the centrifugal/inertial forces caused by the rotation of the earth around the center of mass of the earth-moon system create two "bulges" in the Earth's oceans: one closest to the moon, and the other on the opposite side of the globe.(CNW Group, 2008). This kind of energy is unique and different from traditional hydropower that has been around for centuries. There is no need to build a dam. Essentially a turbine is stuck in naturally flowing water. As the water flows, it turns a turbine. That is converted to electricity.

text: It has an estimated average equilibrium temperature of , very close to that of Earth. If Kepler-61b is Earth-like it is a good candidate for life, because the system is about one billion years old, however because of its radius (2.24 ), it is likely gaseous, with no solid surface. However, this does not totally destroy the chances of habitability in the Kepler-61 system. Kepler-61b may well have a substantially large enough Earth-like moon (with the proper atmospheric properties and pressure), capable of supporting surface liquid water, and potentially life. However, such moons do not form naturally, it would have to be captured.

text: In the case of an infinitesimally small elastic sphere, the effect of a tidal force is to distort the shape of the body without any change in volume. The sphere becomes an ellipsoid with two bulges, pointing towards and away from the other body. Larger objects distort into an ovoid, and are slightly compressed, which is what happens to the Earth's oceans under the action of the Moon. The Earth and Moon rotate about their common center of mass or barycenter, and their gravitational attraction provides the centripetal force necessary to maintain this motion. To an observer on the Earth, very close to this barycenter, the situation is one of the Earth as body 1 acted upon by the gravity of the Moon as body 2. All parts of the Earth are subject to the Moon's gravitational forces, causing the water in the oceans to redistribute, forming bulges on the sides near the Moon and far from the Moon.

text: A simple lunar trajectory stays in one plane, resulting in lunar flyby or orbit within a small range of inclination to the Moon's equator. This also permits a "free return", in which the spacecraft would return to the appropriate position for reentry into the Earth's atmosphere if it were not injected into lunar orbit. Relatively small velocity changes are usually required to correct for trajectory errors. Such a trajectory was used for the Apollo 8, Apollo 10, Apollo 11, and Apollo 12 manned lunar missions.

In this technique, radio wave signals are aimed at the Moon by one location, bounce off the Moon's surface, and are detected by an antenna at a different location on Earth.

text: According to Lucio Russo, Seleucus' arguments for a heliocentric theory were probably related to the phenomenon of tides. The annual cycle of tides (which was studied by Seleucus) can indeed hardly be explained in a geocentric system. Seleucus correctly theorized that tides were caused by the Moon, explaining that the interaction was mediated by the pneuma. He noted that the tides varied in time and strength in different parts of the world. According to Lucio Russo, Seleucus ascribed tides both to the Moon and to a whirling motion of the Earth, which could be interpreted as the motion of the Earth around the Earth-Moon center of mass.

text: There are two profound differences in the chemistry of lunar regolith and soil from terrestrial materials. The first is that the Moon is very dry.  As a result, those minerals with water as part of their structure such as clay, mica, and amphiboles are totally absent from the Moon. The second difference is that lunar regolith and crust are chemically reduced, rather than being significantly oxidized like the Earth's crust. In the case of the regolith, this is due in part to the constant bombardment of the lunar surface with protons (i.e. hydrogen (H) nuclei) from the solar wind. One consequence is that iron on the Moon is found in the metallic 0 and +2 oxidation state, whereas on Earth iron is found primarily in the +2 and +3 oxidation state.

text: like the Earth's crust. In the case of the regolith, this is due in part to the constant bombardment of the lunar surface with protons (i.e. hydrogen (H) nuclei) from the solar wind. One consequence is that iron on the Moon is found in the metallic 0 and +2 oxidation state, whereas on Earth iron is found primarily in the +2 and +3 oxidation state.

text: For many years after Apollo, the binary accretion model was settled on as the best hypothesis for explaining the Moon's origins, even though it was known to be flawed. Then, at a conference in Kona, Hawaii in 1984, a compromise model was composed that accounted for all of the observed discrepancies. Originally formulated by two independent research groups in 1976, the giant impact model supposed that a massive planetary object, the size of Mars, had collided with Earth early in its history. The impact would have melted Earth's crust, and the other planet's heavy core would have sunk inward and merged with Earth's. The superheated vapour produced by the impact would have risen into orbit around the planet, coalescing into the Moon. This explained the lack of water (the vapour cloud was too hot for water to condense), the similarity in composition (since the Moon had formed from part of the Earth), the lower density (since the Moon had formed from the Earth's crust and mantle, rather than its core), and the Moon's unusual orbit (since an oblique strike would have imparted a massive amount of angular momentum to the Earth–Moon system).

text: A hypothetical planet-sized Earth trojan the size of Mars, named Theia, is thought by proponents of the giant-impact hypothesis to be the origin of the Moon. The hypothesis states that the Moon formed after Earth and Theia collided head-on, showering material from the two planets into space. This material eventually accreted around Earth and into a single orbiting body, the Moon.

text: The effect of long-period tides on lunar orbit is a controversial topic, some literatures conclude the long-period tides accelerate the moon and slow down the earth. However Cheng  found that dissipation of the long-period tides brakes the moon and actually accelerates the earth's rotation. To explain this, they assumed the earth's rotation depends not directly on the derivation of the forcing potential for the long period tides, so the form and period of the long-period constituents is independent of the rotation rate. For these constituents, the moon (or sun) can be thought of as orbiting a non-rotating earth in a plane with the appropriate inclination to the equator. Then the tidal "bulge" lags behind the orbiting moon thus decelerating it in its orbit (bringing it closer to the earth), and by angular momentum conservation, the earth's rotation must accelerate. But this argument is qualitative, and a quantitative resolution of the conflicting conclusions is still needed.

text: The U.S. co-launched the Lunar Reconnaissance Orbiter (LRO) and the LCROSS impactor and follow-up observation orbiter on 18 June 2009; LCROSS completed its mission by making a planned and widely observed impact in the crater Cabeus on 9 October 2009, whereas LRO is currently in operation, obtaining precise lunar altimetry and high-resolution imagery. In November 2011, the LRO passed over the Aristarchus crater, which spans  and sinks more than  deep. The crater is one of the most visible ones from Earth. "The Aristarchus plateau is one of the most geologically diverse places on the Moon: a mysterious raised flat plateau, a giant rille carved by enormous outpourings of lava, fields of explosive volcanic ash, and all surrounded by massive flood basalts", said Mark Robinson, principal investigator of the Lunar Reconnaissance Orbiter Camera at Arizona State University. NASA released photos of the crater on 25 December 2011.

text: In representations of the Solar System, it is common to draw the trajectory of Earth from the point of view of the Sun, and the trajectory of the Moon from the point of view of Earth. This could give the impression that the Moon orbits Earth in such a way that sometimes it goes backwards when viewed from the Sun's perspective. Because the orbital velocity of the Moon around Earth (1 km/s) is small compared to the orbital velocity of Earth about the Sun (30 km/s), this never happens. There are no rearward loops in the Moon's solar orbit.

text: Tidal power is taken from the Earth's oceanic tides. Tidal forces are periodic variations in gravitational attraction exerted by celestial bodies. These forces create corresponding motions or currents in the world's oceans. Due to the strong attraction to the oceans, a bulge in the water level is created, causing a temporary increase in sea level.  When the sea level is raised, water from the middle of the ocean is forced to move toward the shorelines, creating a tide.  This occurrence takes place in an unfailing manner, due to the consistent pattern of the moon’s orbit around the earth.  The magnitude and character of this motion reflects the changing positions of the Moon and Sun relative to the Earth, the effects of Earth's rotation, and local geography of the sea floor and coastlines.

text: Naoko Takeuchi's famous Pretty Soldier Sailor Moon, which has seen life as a manga series, two anime series, a live-action television show, three anime movies, and a series of stage musicals, blends elements of the story of Princess Kaguya and the Greek myth of Endymion. The series' titular superheroine's civilian name, Tsukino Usagi, means "Rabbit of the Moon," and she is the reincarnation of Princess Serenity of the Moon Kingdom, which flourished over a millennium ago until destroyed by evil forces. The Princess had been enamored of the Earth Prince Endymion, who himself was reborn as Chiba Mamoru, secretly the dapper superhero Tuxedo Kamen, or Tuxedo Mask. The name Endymion came from a Greek tale of a young shepherd (in some retellings a king) who was beloved of the moon goddess Selene, daughter of Zeus.

text: Newer research suggests that the reason the side of the moon facing Earth has fewer impact craters is heat from Earth at the time when the Moon was formed. The lunar crust consists primarily of plagioclases formed when aluminium and calcium condensed and combined with silicates in the mantle. The cooler far side experienced condensation of these elements sooner and so formed a thicker crust; meteoroid impacts on the near side would sometimes penetrate the thinner crust here and release basaltic lava that created the maria, but would rarely do so on the far side.

text: Constructions like those in Newton's diagram can be repeated for many different positions of the Moon in its orbit. For each position, the result is a perturbation vector like LS1 or LS2 in the second diagram. Shown here is an often-presented form of the diagram that summarises sizes and directions of the perturbation vectors for many different positions of the Moon in its orbit. Each small arrow is a perturbation vector like LS, applicable to the Moon in the particular position around the orbit from which the arrow begins. The perturbations on the Moon when it is nearly in line along the Earth-Sun axis, i.e. near new or full moon, point outwards, away from the Earth. When the Moon-Earth line is 90° from the Earth-Sun axis they point inwards, towards the Earth, with a size that is only half the maximum size of the axial (outwards) perturbations. (Newton gave a rather good quantitative estimate for the size of the solar perturbing force: at quadrature where it adds to the Earth's attraction he put it at 1/178.725 of the mean terrestrial attraction, and twice as much as that at the new and full moons where it opposes and diminishes the Earth's attraction.)

text: In 1957 Hans Peterson conducted one of the first direct measurements of the fall of space dust on the Earth, estimating it to be 14,300,000 tons per year. If this were true, then the Moon would be covered to a very great depth as there are limited forms of erosion to remove this material. In 1961 Arthur C. Clarke popularized this possibility in his novel A Fall of Moondust. This was cause for some concern among the groups attempting to land on the Moon, so a series of new studies followed to better characterize the issue. This included the launch of several spacecraft designed to directly measure the micrometeorite flux (Pegasus satellite program) or directly measure the dust on the surface of the Moon (Surveyor Program). These showed that the flux was much lower than earlier estimates, around 10,000 to 20,000 tons per year, and that the surface of the Moon is relatively rocky. Most lunar samples returned during the Apollo Program have micrometeorite impacts marks, typically called "zap pits", on their upper surfaces.

To the southeast is the crater Lavoisier, and to the northeast lies Gerard. Northwest of Bunsen, on the far side of the Moon, is McLaughlin. Due to its position this crater appears foreshortened when viewed from the Earth, and its visibility is affected by libration.

text: As noted above, the Moon's orbit is also elliptical. The Moon's distance from the Earth can vary by about 6% from its average value. Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses. The distance of the Earth from the Sun also varies during the year, but this is a smaller effect. On average, the Moon appears to be slightly smaller than the Sun as seen from the Earth, so the majority (about 60%) of central eclipses are annular. It is only when the Moon is closer to the Earth than average (near its perigee) that a total eclipse occurs.

text: This planet may have Earth-like moons with bodies of water and possibly life. But giving the planet's high eccentricity, life on the moons may not evolve as well as those on Earth. From the surface of the moon, ones may see parent planet in the sky about half of the times with different phases just like the Moon seen from Earth, as well as other moons. If this planet has rings nearly as prominent as Saturn's, then the rings can be seen surrounding the planet, making this scenery even more amazing.

WASH in schools, sometimes called SWASH or WinS, significantly reduces hygiene related disease, increases student attendance and contributes to dignity and gender equality. WASH in Schools contributes to healthy, safe and secure school environments that can protect children from health hazards, abuse and exclusion. It also enables children to become agents of change for improving water, sanitation and hygiene practices in their families and communities.

text: The Moon is in synchronous rotation with Earth, always showing the same face, with its near side marked by dark volcanic maria that fill the spaces between the bright ancient crustal highlands and the prominent impact craters. It is the second-brightest regularly visible celestial object in Earth's sky, after the Sun, as measured by illuminance on Earth's surface. Its surface is actually dark, although compared to the night sky it appears very bright, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its regular cycle of phases have made the Moon an important cultural influence since ancient times on language, calendars, art, mythology, and, it is often speculated, the menstrual cycles of the female of the human species.

text: In May 1902, Méliès made his most famous film, A Trip to the Moon. It was loosely based on Jules Verne's From the Earth to the Moon and H. G. Wells' The First Men in the Moon. In the film, Méliès stars as Professor Barbenfouillis, a character similar to the astronomer he played in The Astronomer's Dream in 1898. Professor Barbenfouillis is the President of the Astronomer's Club and proposes an expedition to the Moon. A space vehicle in the form of a large artillery shell is built in his laboratory, and he uses it to launch six men (including himself) on a voyage to the Moon. The vehicle is shot out of a large cannon into space and hits the Man in the Moon in the eye. The group explores the Moon's surface before going to sleep. As they dream, they are observed by the Moon goddess Phoebe, played by Bleuette Bernon, who causes it to snow. Later, while underground, they are attacked and captured by a group of Moon aliens, played by acrobats from the Folies Bergère. Taken before the alien king, they manage to escape and are chased back to their spaceship. Then, with the aid of a rope attached to the spaceship, the men, along with an alien, fall from the Moon back to Earth, landing in the ocean (where a superimposed fish tank creates the illusion of the deep ocean). Eventually the spaceship is towed ashore and the returning adventurers are celebrated by the townspeople. At 14 minutes, it was Méliès' longest film up to that date and cost 10,000 francs to produce.

Eventually the spaceship is towed ashore and the returning adventurers are celebrated by the townspeople. At 14 minutes, it was Méliès' longest film up to that date and cost 10,000 francs to produce.

text: Tidal forces from Earth have slowed down the Moon's rotation so that the same side is always facing the Earth, a phenomenon called tidal locking. The other face, most of which is never visible from the Earth, is therefore called the "far side of the Moon". Over time some parts of the far side can be seen due to libration. In total 59 percent of the Moon's surface is visible from Earth at one time or another. Useful observation of the parts of the far side of the Moon occasionally visible from Earth is difficult because of the low viewing angle from Earth (they cannot be observed "full on").

text: As seen from the Earth, the time it takes for the Moon to return to a node, the draconic month, is less than the time it takes for the Moon to return to the same ecliptic longitude as the Sun: the synodic month. The main reason is that during the time that the Moon has completed an orbit around the Earth, the Earth (and Moon) have completed about  of their orbit around the Sun: the Moon has to make up for this in order to come again into conjunction or opposition with the Sun. Secondly, the orbital nodes of the Moon precess westward in ecliptic longitude, completing a full circle in about  18.60 years, so a draconic month is shorter than a sidereal month. In all, the difference in period between synodic and draconic month is nearly  days. Likewise, as seen from the Earth, the Sun passes both nodes as it moves along its ecliptic path. The period for the Sun to return to a node is called the eclipse or draconic year: about 346.6201 d, which is about  year shorter than a sidereal year because of the precession of the nodes.

text: In June 1977, NASA issued a fact sheet responding to recent claims that the Apollo Moon landings had been hoaxed. The fact sheet is particularly blunt and regards the idea of faking the Moon landings to be preposterous and outlandish. NASA refers to the rocks and particles collected from the Moon as being evidence of the program's legitimacy, as they claim that these rocks could not have been formed under conditions on earth. NASA also notes that all of the operations and phases of the Apollo program were closely followed and under the scrutiny of the news media, from liftoff to splashdown. NASA responds to Bill Kaysing's book, We Never Went to the Moon, by identifying one of his claims of fraud regarding the lack of a crater left on the Moon's surface by the landing of the lunar module, and refuting it with facts about the soil and cohesive nature of the surface of the Moon.

text: Theories for the formation of the Moon must explain its late formation as well as the following facts. First, the Moon has a low density (3.3 times that of water, compared to 5.5 for the earth) and a small metallic core. Second, there is virtually no water or other volatiles on the moon. Third, the Earth and Moon have the same oxygen isotopic signature (relative abundance of the oxygen isotopes). Of the theories that have been proposed to account for these phenomena, only one is widely accepted: The giant impact hypothesis  proposes that the Moon originated after a body the size of Mars (sometimes named Theia) struck the proto-Earth a glancing blow.

text: Gernsback is a lunar crater on the far side of the Moon. It is located in the northeastern part of the uneven Mare Australe, just behind the southeastern limb. During periods of favorable libration this feature can be brought into view of the Earth, but it is seen from the side and not much detail can be observed. It is located about a crater diameter north of the larger crater Lamb, and southwest of Parkhurst.

text: The far side of the Moon is the hemisphere of the Moon that always faces away from Earth. The far side's terrain is rugged, with a multitude of impact craters and relatively few flat lunar maria. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. Although both sides of the moon experience two weeks of sunlight followed by two weeks of night, the far side is also referred to as the dark side of the Moon, originally in the sense of "unknown" rather than lack of light.

text: The more detailed models include (among other things) the bulging at the equator for the Earth, and irregular mass concentrations (due to meteor impacts) for the Moon.  The Gravity Recovery And Climate Experiment (GRACE) mission launched in 2002 consists of two probes, nicknamed "Tom" and "Jerry", in polar orbit around the Earth measuring differences in the distance between the two probes in order to more precisely determine the gravitational field around the Earth, and to track changes that occur over time.  Similarly, the Gravity Recovery and Interior Laboratory (GRAIL) mission from 2011-2012 consisted of two probes ("Ebb" and "Flow") in polar orbit around the Moon to more precisely determine the gravitational field for future navigational purposes, and to infer information about the Moon's physical makeup.

text: In effect, this means that the "tropical year" on the moon is only 347 days long. This is called the draconic year or eclipse year. The "seasons" on the moon fit into this period. For about half of this draconic year, the sun is north of the lunar equator (but at most 1.543°), and for the other half it is south of the lunar equator. Obviously the effect of these seasons is very minor compared to the difference between lunar night and lunar day. At the poles, there are not days and nights of about 15 earth days, but rather the sun will be "up" for 173 days at a time. "Up" here means that the centre of the sun is above the horizon. The sunrise and sunset at the poles each take about 18 days. These polar sunrises and sunsets occur around the time of eclipses (solar or lunar). For example, at the Solar eclipse of March 9, 2016, the moon was near its descending node, and the sun was near the point in the sky where the equator of the moon crosses the ecliptic. When the sun reached that point, the centre of the sun set at the north pole and rose at the south pole.

text: or eclipse year. The "seasons" on the moon fit into this period. For about half of this draconic year, the sun is north of the lunar equator (but at most 1.543°), and for the other half it is south of the lunar equator. Obviously the effect of these seasons is very minor compared to the difference between lunar night and lunar day. At the poles, there are not days and nights of about 15 earth days, but rather the sun will be "up" for 173 days at a time. "Up" here means that the centre of the sun is above the horizon. The sunrise and sunset at the poles each take about 18 days. These polar sunrises and sunsets occur around the time of eclipses (solar or lunar). For example, at the

text: , the moon was near its descending node, and the sun was near the point in the sky where the equator of the moon crosses the ecliptic. When the sun reached that point, the centre of the sun set at the north pole and rose at the south pole.

text: Space elevator designs for Earth typically have a taper of the tether that provides a uniform stress profile rather than a uniform cross-section. Because the strength requirement of a lunar space elevator is much lower than that of an Earth space elevator, a uniform cross-section is possible for the lunar space elevator. The study done for NASA's Institute of Advanced Concepts states "Current composites have characteristic heights of a few hundred kilometers, which would require taper ratios of about 6 for Mars, 4 for the Moon, and about 6000 for the Earth. The mass of the Moon is small enough that a uniform cross-section lunar space elevator could be constructed, without any taper at all." A uniform cross-section could make it possible for a lunar space elevator to be built in a double-tether pulley configuration. This configuration would greatly simplify repairs of a space elevator compared to a tapered elevator configuration. However a pulley configuration would require a strut at the counterweight hundreds of kilometers long to separate the up-tether from the down-tether and keep them from tangling. A pulley configuration might also allow the system capacity to be gradually expanded by stitching new tether material on at the Lagrange point as the tether rotated.

text: The Lunar Reconnaissance Orbiter (LRO) is the first mission of the LPRP program. Management of LRO was assigned to Goddard Space Flight Center (GSFC) in 2004. LRO launched on an Atlas V 401 rocket from Cape Canaveral Air Force Station on June 18, 2009 at 5:32 p.m. EDT (2132 GMT). The planned lift off for 5:12 p.m. EDT (2112 GMT) was slightly delayed by 20 minutes due to thunderstorms. It will orbit the Moon for one year, gathering high resolution images of the lunar surface that will allow the creation of detailed maps. LRO's goals include finding safe landing sites for human visits to the Moon, identifying lunar resources, and studying the lunar radiation environment. The LRO will provide a 3-D map of the Moon's surface to allow astronauts to return to the Moon by 2020. On board the LRO are seven instruments, the Cosmic Ray Telescope for the Effects of Radiation (CRaTER), Diviner Lunar Radiometer Experiment (DLRE), Lyman-Alpha Mapping Project (LAMP), Lunar Exploration Neutron Detector (LEND), Lunar Orbiter Laser Altimeter (LOLA), Lunar Reconnaissance Orbiter Camera (LROC), and Miniature Radio Frequency radar (Mini-RF).

text: Scholars have theorized that Hjúki and Bil may represent lunar activity, including that they may represent the phases of the moon or may represent the craters of the moon. 19th century scholar Jacob Grimm rejects the suggestion that Hjúki and Bil represent the phases of the moon, and states that Hjúki and Bil rather represent the craters on the moon seen from the earth. Grimm says that the evidence for this "is plain from the figure itself. No change of the moon could suggest the image of two children with a pail slung over their shoulders. Moreover, to this day the Swedish people see in the spots of the moon two persons carrying a big bucket on a pole." Grimm adds that:

text: For a planet, angular momentum is distributed between the spin of the planet and its revolution in its orbit, and these are often exchanged by various mechanisms. The conservation of angular momentum in the Earth–Moon system results in the transfer of angular momentum from Earth to Moon, due to tidal torque the Moon exerts on the Earth. This in turn results in the slowing down of the rotation rate of Earth, at about 65.7 nanoseconds per day, and in gradual increase of the radius of Moon's orbit, at about 3.82 centimeters per year.

text: Lunar eclipses can occur only at full moon, where the Moon's orbit allows it to pass through Earth's shadow. Lunar eclipses do not occur every month because the Moon usually passes above or below Earth's shadow (which is mostly restricted to the ecliptic plane). Lunar eclipses can occur only when the full moon occurs near the two nodes of the orbit, either the ascending or descending node. This causes eclipses to only occur about every 6 months, and often 2 weeks before or after a solar eclipse at new moon at the opposite node.

text: The Soviet space program comprised the rocketry and space exploration programs conducted by the former Soviet Union (USSR) from the 1930s until its dissolution in 1991. Over its sixty-year history, this primarily classified military program was responsible for a number of pioneering accomplishments in space flight, including the first intercontinental ballistic missile (R-7), first satellite (Sputnik 1), first animal in Earth orbit (the dog Laika on Sputnik 2), first human in space and Earth orbit (cosmonaut Yuri Gagarin on Vostok 1), first woman in space and Earth orbit (cosmonaut Valentina Tereshkova on Vostok 6), first spacewalk (cosmonaut Alexey Leonov on Voskhod 2), first Moon impact (Luna 2), first image of the far side of the moon (Luna 3) and unmanned lunar soft landing (Luna 9), first space rover (Lunokhod 1), first sample of lunar soil automatically extracted and brought to Earth (Luna 16), and first space station (Salyut 1). Further notable records included the first interplanetary probes: Venera 1 and Mars 1 to fly by Venus and Mars, respectively, Venera 3 and Mars 2 to impact the respective planet surface, and Venera 7 and Mars 3 to make soft landings on these planets.

text: Carpenter is a lunar impact crater in the northern part of the Moon, relatively close to the limb (as viewed from earth). At this position the crater is foreshortened and appears oval in shape. It is, however, very nearly circular in outline. The outer rampart to the south is adjoined to the old crater Anaximander, and the satellite formation Anaximander B lies along the western rim. To the northeast is Anaximenes.

text: Paul Calle (pronounced KAL-ee; March 3, 1928 – December 30, 2010) was an American artist who was best known for the designs he created for postage stamps, including 40 that were released by the United States Postal Service, and others for stamps issued by the Federated States of Micronesia, the Marshall Islands, Sweden and the United Nations. The sole artist hired by NASA to cover the Apollo 11 astronauts up close, Calle designed the 10-cent stamp that commemorated the first manned moon landing; it depicted an astronaut stepping onto the moon from the lunar module, with the Earth visible over the moon's horizon.

text: The crater interior has a relatively high albedo, making it a prominent feature when the Moon is nearly full. (The high latitude of the crater means that the Sun always remains close to the horizon even at maximum elevation less than a day after Full Moon.) The interior walls are steep and possess a system of terraces. The central peak is offset from the crater midpoint, and joins a low range across the crater floor.  In fact, it appears that some of the central peak material has landed outside the crater rim.

text: The Moon's existence is widely attributed to a huge impact early in Earth's history. Impact events earlier in the history of Earth have been credited with creative as well as destructive events; it has been proposed that impacting comets delivered the Earth's water, and some have suggested that the origins of life may have been influenced by impacting objects by bringing organic chemicals or lifeforms to the Earth's surface, a theory known as exogenesis.

text: Since 1936, Escher’s work had become primarily focused on paradoxes, tessellation and other abstract visual concepts. This print, however, is a realistic depiction of a simple image that portrays two perspectives at once. It depicts an unpaved road with a large pool of water in the middle of it at twilight. Turning the print upside-down and focusing strictly on the reflection in the water, it becomes a depiction of a forest with a full moon overhead. The road is soft and muddy and in it there are two distinctly different sets of tire tracks, two sets of footprints going in opposite directions and two bicycle tracks. Escher has thus captured three elements: the water, sky and earth.

text: Because the lunar orbit is also inclined to Earth's ecliptic plane by 5.1°, the rotational axis of the Moon seems to rotate towards and away from Earth during one complete orbit. This is referred to as latitudinal libration, which allows one to see almost 7° of latitude beyond the pole on the far side. Finally, because the Moon is only about 60 Earth radii away from Earth's centre of mass, an observer at the equator who observes the Moon throughout the night moves laterally by one Earth diameter. This gives rise to a diurnal libration, which allows one to view an additional one degree's worth of lunar longitude. For the same reason, observers at both of Earth's geographical poles would be able to see one additional degree's worth of libration in latitude.

text: A lunar occultation occurs when the Moon, moving along its orbital path, passes in front of a star or other celestial object, as seen by an observer (normally on the Earth).  A grazing lunar occultation (also lunar grazing occultation, lunar graze, or just graze) occurs when one of the two edges of the moon parallel to its orbital path appears to just touch or graze the object as the moon goes by.  When this happens, a properly positioned observer will see the grazed object disappear and reappear, possibly several times, as mountains and valleys on the edge of the moon pass in front of it.

text: Every 18.6 years, the angle between the moon's orbit and the earth's equator reaches a maximum of 28°36′ (the sum of the Earth's inclination 23°27′ and the Moon's inclination 5°09′). This is called major lunar standstill. Around this time, the moon's latitude will vary from −28°36′ to +28°36′. 9.3 years later, the angle between the moon's orbit and the earth's equator reaches its minimum, 18°20′. This is called a minor lunar standstill.

text: The Moon's regular phases make it a very convenient timepiece, and the periods of its waxing and waning form the basis of many of the oldest calendars. Tally sticks, notched bones dating as far back as 20–30,000 years ago, are believed by some to mark the phases of the Moon.The ~30-day month is an approximation of the lunar cycle.The English noun month and its cognates in other Germanic languages stem from Proto-Germanic *mǣnṓth-, which is connected to the above-mentioned Proto-Germanic *mǣnōn, indicating the usage of a lunar calendar among the Germanic peoples (Germanic calendar) prior to the adoption of a solar calendar. The PIE root of moon, *méhnōt, derives from the PIE verbal root *meh-, "to measure", "indicat[ing] a functional conception of the moon, i.e. marker of the month" (cf. the English words measure and menstrual), and echoing the Moon's importance to many ancient cultures in measuring time (see Latin ''mensis'' and Ancient Greek ''μείς'' (meis) or  (mēn), meaning "month").Most historical calendars are lunisolar. The 7th-century Islamic calendar is an exceptional example of a purely lunar calendar. Months are traditionally determined by the visual sighting of the hilal, or earliest crescent moon, over the horizon.

text: The organization is the creator of World Moon Bounce Day. A global event where both commercial and amateur radio operators bounce signals off the surface of the Moon and back to Earth. World Moon Bounce Day was first celebrated on June 27, 2009 (GMT) with some events starting some hours earlier. Countries around the world participate as the Earth turns and during a 24-hour event the Moon is visible to all countries. In amateur circles, the activities are also known as EME (communications) (Earth-Moon-Earth). The first World Moon Bounce Day had Apollo astronaut Bill Anders as a guest. His interview was bounced off the Moon as part of the activities. The University of Tasmania in Australia with their 26m dish was able to bounce a data signal off the surface of the Moon which was received by a large dish in the Netherlands. The data signal was successfully resolved back to data setting a world record for the lowest power data signal returned from the Moon with a transmit power of 3mW - about 1,000th of the power of a strong flashlight filament globe.

text: For almost five millennia, the geocentric model of the Earth as the center of the universe had been accepted by all but a few astronomers. In Aristotle's cosmology, Earth's central location was perhaps less significant than its identification as a realm of imperfection, inconstancy, irregularity and change, as opposed to the "heavens", (Moon, Sun, planets, stars) which were regarded as perfect, permanent, unchangeable, and in religious thought, the realm of heavenly beings. The Earth was even composed of different material, the four elements "earth", "water", "fire", and "air", while sufficiently far above its surface (roughly the Moon's orbit), the heavens were composed of different substance called "aether". The heliocentric model that replaced it involved not only the radical displacement of the earth to an orbit around the sun, but its sharing a placement with the other planets implied a universe of heavenly components made from the same changeable substances as the Earth. Heavenly motions no longer needed to be governed by a theoretical perfection, confined to circular orbits.

text: In his speech that opens the episode, the Lunar Controller states that the Moon is home to about 4,000 humans. In Tony Barwick's original script, the character was then to discuss the self-sufficiency of lunar bases in greater detail, stating, for example, "We were all born on Earth, but I see a future where men will be born, spend their lives and die on the Moon." This dialogue was edited out of the finished episode. The appearance of the Moonmobiles that feature in "Lunarville 7" and its sequel, "Crater 101", influenced the design of the SHADO Moonmobiles that would appear in the later Century 21 TV series, UFO. The incidental music for this episode makes extensive use of an Ondes Martenot, played by composer Barry Gray himself, for sequences set in and around Lunarville 7. The music was recorded in the same studio session as that for "The Launching", on  with four instrumentalists in attendance.

text: A fourth influence occurs because the orbit of the moon around the earth and the orbit the of the earth around the sun are elliptical rather than circular. The effect of this is that the time between high tides changes a little from day to day. The moon takes about 24.8 hours to orbit around the earth, so it takes half this time, 12.4 hours, for the M2 tides to occur. The tides can be predicted far in advance, because the moon and earth have orbits that are predictable. The National Institute of Water and Atmospheric Research (NIWA) run a tidal computer model specific to New Zealand.

text: Many factors can affect the appearance of the Moon during a lunar eclipse.  The Moon's path through the Earth's umbra is important, but so too are the current conditions of the Earth's atmosphere.  While the Earth's shadow blocks any direct light from striking the Moon during a lunar eclipse, some light is refracted through the Earth's atmosphere giving a Moon a red hue.

text: While the giant impact hypothesis might explain many lines of evidence, there are still some unresolved questions, most of which involve the Moon's composition.In 2001, a team at the Carnegie Institute of Washington reported the most precise measurement of the isotopic signatures of lunar rocks. To their surprise, the team found that the rocks from the Apollo program carried an isotopic signature that was identical with rocks from Earth, and were different from almost all other bodies in the Solar System. Because most of the material that went into orbit to form the Moon was thought to come from Theia, this observation was unexpected. In 2007, researchers from the California Institute of Technology announced that there was less than a 1% chance that Theia and Earth had identical isotopic signatures. Published in 2012, an analysis of titanium isotopes in Apollo lunar samples showed that the Moon has the same composition as Earth, which conflicts with what is expected if the Moon formed far from Earth's orbit or from Theia. Variations on the giant impact hypothesis may explain this data.

text: The lunar maria  (singular: mare ) are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich compositions, and hence appear dark to the naked eye. The maria cover about 16 percent of the lunar surface, mostly on the side visible from Earth. The few maria on the far side are much smaller, residing mostly in very large craters. The traditional nomenclature for the Moon also includes one oceanus (ocean), as well as features with the names lacus (lake), palus (marsh), and sinus (bay). The last three are smaller than maria, but have the same nature and characteristics.

text: During ashfall events large demands are commonly placed on water resources for cleanup and shortages can result. Shortages compromise key services such as firefighting and can lead to a lack of water for hygiene, sanitation and drinking. Municipal authorities need to monitor and manage this water demand carefully, and may need to advise the public to utilise cleanup methods that do not use water (e.g., cleaning with brooms rather than hoses).

text: When the Earth, moon, and sun are in line (sun–Earth–moon, or sun–moon–Earth) the two main influences combine to produce spring tides; when the two forces are opposing each other as when the angle moon–Earth–sun is close to ninety degrees, neap tides result. As the moon moves around its orbit it changes from north of the equator to south of the equator. The alternation in high tide heights becomes smaller, until they are the same (at the lunar equinox, the moon is above the equator), then redevelop but with the other polarity, waxing to a maximum difference and then waning again.

text: During a meteor shower said to be the most spectacular in 10,000 years, an asteroid hidden by the meteor field strikes the Moon. Fragments of the asteroid and of the Moon itself penetrate Earth's atmosphere and make impact.  The initial damage is minimal, though significant physical damage to the lunar surface can be seen from Earth.  Experts believe that the Moon has stabilized into a slightly closer orbit. Then strange anomalies begin to manifest themselves on Earth, including cell phone disruptions, unusual static discharges and odd tidal behavior. The world's leading scientists, including Alex Kittner, Maddie Rhodes, and Roland Emerson, begin piecing together evidence that suggests the moon's properties have been permanently altered because the asteroid that hit the Moon was actually a fragment of a brown dwarf; the fragment is highly magnetized and more massive than the Earth despite being only 19 kilometers across, and it is still inside the moon.  When the Moon's new, more elliptical orbit brings it closer to Earth, electromagnetic surges begin affecting the surface, causing people, vehicles, and other objects to levitate at random, worldwide.  Alex, Maddie, Roland and the rest of their team soon discover that the Moon's new orbit will cause it to collide with the Earth in 39 days, completely destroying the planet.  After a failed attempt by the United States to destroy the Moon with nuclear weapons, the three scientists plan an international mission to the Moon, where astronauts must construct a device to magnetize the Moon's core, causing it to disgorge the embedded brown dwarf fragment, eliminating the magnetic effects and restoring the Moon to a stable orbit.  Because of their unique expertise, Alex and Roland must join an American astronaut and a Russian cosmonaut on the mission, which is expected to be a one-way trip.

text: On the near side of the Moon, the strength-to-density required of the tether of a lunar space elevator exists in currently available materials. A lunar space elevator would be about  long. Since the Moon does not rotate fast enough, there is no effective lunar-stationary orbit, but the Lagrangian points could be used. The near side would extend through the Earth-Moon L1 point from an anchor point near the center of the visible part of Earth's Moon.

text: In 2011, planetary scientists Erik Ahsphaug and Martin Jutzi published a study proposing that the uneven distribution of maria occurred because the moon collided with another, smaller moon of the earth, a few million years after its formation. In this low-impact collision, the smaller moon was crushed into the surface of the moon, thickening the moon's crust on one side. Subsequent impacts broke through the crust and released lava only where the crust was thin, leading to the observed uneven distribution of maria.

The climate of Mars may have been such in the past that water ran on its surface.  It has been known for some time that Mars undergoes many large changes in its tilt or obliquity because its two small moons lack the gravity to stabilize it, as our moon stabilizes Earth; at times the tilt has even been greater than 80 degrees

text: Controlling the location of impact for spent lunar orbiters can have scientific value. For example, in 1999 the NASA Lunar Prospector orbiter was deliberately targeted to impact a permanently shadowed area of Shoemaker Crater near the lunar south pole. It was hoped that energy from the impact would vaporize suspected shadowed ice deposits in the crater and liberate a water vapor plume that would be detectable from Earth. No such plume was observed. However, a small vial of ashes from the body of pioneer lunar scientist Eugene Shoemaker was delivered by the Lunar Prospector to the crater named in his honor – currently the only human remains on the Moon.

text: Moon gardeners maintain that not only is science on their side, but also that the results are plain to see. According to the theory, plants that are sown in the few days before a full moon become stronger and more productive. The moon gardeners claim that the gravitational force of the full moon affects the level of groundwater in the soil, just as it does the level of the oceans. With more water being drawn up into the soil during a full moon, any newly sown seeds are boosted by the increased hydration. It should be noted that the phases of the moon do not correspond to the distance of the moon's orbit around the Earth, and hence are not indicators of the strength of the moon's gravitational pull. Instead, apogee and perigee of the moon's orbit are what determines the moon's distance to the Earth.

text: Another hypothesis attributes the formation of the Moon to the impact of a large asteroid with the Earth much later than previously thought, creating the satellite primarily from debris from Earth. In this hypothesis, the formation of the Moon occurs 60–140 million years after the formation of the Solar System. Previously, the age of the Moon had been thought to be 4.527 ± 0.010 billion years. The impact in this scenario would have created a magma ocean on Earth and the proto-Moon with both bodies sharing a common plasma metal vapour atmosphere. The shared metal vapour bridge would have allowed material from the Earth and proto-Moon to exchange and equilibrate into a more common composition.

text: The Weak Equivalence Principle says that all objects fall the same way in a gravity field, no matter what they are made of. The Earth and the Moon have very different compositions—for example, the Earth has a large iron core, but the Moon does not. Furthermore, both are in orbit around the Sun, meaning they are both falling towards the Sun at all times, even as they revolve around each other. If the Earth and the Moon were affected differently by the gravity of the Sun, this would directly affect the orbit of the Moon around the Earth. But as closely as scientists can measure, the orbit of the Moon is just as predicted from assuming that gravity acts the same on each — to within 1 part in , the Earth and the Moon fall towards the Sun in exactly the same way, despite their different compositions. APOLLO will lead to even tighter limits.

text: Moonlight photography (taking pictures of the surface of the Earth as illuminated by moonlight) is very different from lunar photography (taking pictures of the surface of the Moon as illuminated by sunlight). The Moon has an effective albedo of approximately 0.12, comparable to fresh asphalt. Since it is essentially a dark rock in full sunlight, photographing its surface needs an exposure comparable to what a photographer would use for ordinary mid-brightness surfaces (buildings, trees, faces, etc.) with an overcast sky.

text: Helberg is a lunar crater that is located just behind the western limb of the Moon, on the far side from the Earth. Due to libration this part of the surface is sometimes brought into view, and the crater is visible under suitable lighting conditions. However even under these circumstances the crater is viewed from the edge and not much detail can be seen.

text: Hohmann is a lunar crater that lies within the central basin of the Mare Orientale formation, on the farside of the Moon. It is located to the south of the crater Maunder, and to the west of Kopff crater. Due to its proximity to the western lunar limb, this area of the surface is occasionally visible during favorable librations. However the basin is viewed from the side, restricting the amount of detail that can be observed from Earth.

text: Due to tidal acceleration, the orbit of the Moon around the Earth becomes about 2.2 cm more distant each year. It is estimated that, in slightly less than 1.4 billion years, the distance from the Earth to the Moon will have increased by 30,400 km. During that period, the apparent angular diameter of the Moon will decrease in size, meaning that it will no longer be able to completely cover the Sun's disk as seen from the Earth. This will be true even when the Moon is at perigee, and the Earth at aphelion. Moreover, the Sun is increasing in diameter by about 5% per billion years. Therefore, the last total solar eclipse on Earth will occur about six hundred million years from now.

text: A Trip to the Moon () is a 1902 French silent film directed by Georges Méliès. Inspired by a wide variety of sources, including Jules Verne's novels From the Earth to the Moon and Around the Moon, the film follows a group of astronomers who travel to the Moon in a cannon-propelled capsule, explore the Moon's surface, escape from an underground group of Selenites (lunar inhabitants), and return to Earth with a captive Selenite. It features an ensemble cast of French theatrical performers, led by Méliès himself in the main role of Professor Barbenfouillis, and is filmed in the overtly theatrical style for which Méliès became famous.

text: The rotational angular momentum of Earth decreases and consequently the length of the day increases. The net tide raised on Earth by the Moon is dragged ahead of the Moon by Earth's much faster rotation. Tidal friction is required to drag and maintain the bulge ahead of the Moon, and it dissipates the excess energy of the exchange of rotational and orbital energy between Earth and the Moon as heat. If the friction and heat dissipation were not present, the Moon's gravitational force on the tidal bulge would rapidly (within two days) bring the tide back into synchronization with the Moon, and the Moon would no longer recede. Most of the dissipation occurs in a turbulent bottom boundary layer in shallow seas such as the European Shelf around the British Isles, the Patagonian Shelf off Argentina, and the Bering Sea.

text: It is natural to visualize this phenomenon as an abundance of stationary photons within the same ray of light creating the spot on the moon. To allow the image to move from one end of the moon to the other, each photon must move laterally with the movement of the projection. In reality this is not the case, the ray of light is a collection of moving photons and at each instant a different group of photons, detected by the observers eye, are creating the image seen on the surface of the moon. The apparent lateral movement is caused by new photons traveling on a different path from the light source to the moon, caused by the rotation of the source, striking an adjacent position at all instances during the rotation. This is depicted in Figure 3, the movement from point A to point B can be visualized by a collection of photons each travelling along a different trajectory from Earth to the moon. The paradox is resolved to be a result of the geometry of the system causing the illusion of superluminal motion, rather than superluminal motion actually occurring.

text: The celestial sphere can thus be thought of as a kind of astronomical shorthand, and is applied very frequently by astronomers. For instance, the Astronomical Almanac for 2010 lists the apparent geocentric position of the Moon, 1 Jan 2010 at 0h Terrestrial Time, in equatorial coordinates, as right ascension 6 57 48.86, declination +23° 30' 05".5. Implied in this position is that it is as projected onto the celestial sphere; any observer at any location looking in that direction would see the "geocentric Moon" in the same place against the stars. For many rough uses (for instance, calculating an approximate phase of the Moon), this position, as seen from the Earth's center, is adequate. For applications requiring precision (for instance, calculating the shadow path of an eclipse), the Almanac gives formulae and methods for calculating the topocentric coordinates, that is, as seen from a particular place on the Earth's surface, based on the geocentric position. This greatly abbreviates the amount of detail necessary in such almanacs, as each observer can handle their own specific circumstances.

text: In a different gravitational field, for example, on the surface of the Moon, an object can have a significantly different weight than on Earth. The gravity on the surface of the Moon is only about one-sixth as strong as on the surface of the Earth. A one-kilogram mass is still a one-kilogram mass (as mass is an extrinsic property of the object) but the downward force due to gravity, and therefore its weight, is only one-sixth of what the object would have on Earth. So a man of mass 180 pounds weighs only about 30 pounds-force when visiting the Moon.

text: On the makeup of the Moon rocks, Kaysing asked: "Why was there never a mention of gold, silver, diamonds or other precious metals on the moon? Wasn't this a viable consideration? Why was this fact never discussed [sic] in the press or by the astronauts?" Geologists realize that gold and silver deposits on Earth are the result of the action of hydrothermal fluids concentrating the precious metals into veins of ore. Since in 1969 water was believed to be absent on the Moon, no geologist would bother discussing the possibility of finding these on the Moon in any great amount.

text: In the game, humanity has colonized the Moon and Mars. However, a 20 trillion ton asteroid has collided with Earth, making it uninhabitable. All that is left of humanity is a small, self-sufficient colony on the surface of the Moon, and a race of mutant humans on Mars. As the commander of Moonbase, it is your job to ensure the survival of mankind by exploring the Solar System for other habitable planets and moons, and ultimately re-establish life on Earth. However, the Martian mutants consider themselves the superior race and want Earth for themselves, meaning a war is inevitable.

text: A spacecraft performs TLI to begin a lunar transfer from a low circular parking orbit around Earth.  The large TLI burn, usually performed by a chemical rocket engine, increases the spacecraft's velocity, changing its orbit from a circular low Earth orbit to a highly eccentric orbit.  As the spacecraft begins coasting on the lunar transfer arc, its trajectory approximates an elliptical orbit about the Earth with an apogee near to the radius of the Moon's orbit.  The TLI burn is sized and timed to precisely target the Moon as it revolves around the Earth.   The burn is timed so that the spacecraft nears apogee as the Moon approaches.  Finally, the spacecraft enters the Moon's sphere of influence, making a hyperbolic lunar swingby.

text: Earlier it was assumed that Rhea had a rocky core in the center. However measurements taken during a close flyby by the Cassini orbiter in 2005 (see below) cast this into doubt. In a paper published in 2007 it was claimed that the axial dimensionless moment of inertia coefficient was 0.4. Such a value indicated that Rhea had an almost homogeneous interior (with some compression of ice in the center) while the existence of a rocky core would imply a moment of inertia of about 0.34. In the same year another paper claimed the moment of inertia was about 0.37 implying that Rhea was partially differentiated. A year later yet another paper claimed that the moon may not be in hydrostatic equilibrium meaning that the moment of inertia can not be determined from the gravity data alone. In 2008 an author of the first paper tried to reconcile these three disparate results. He concluded that there is a systematic error in the Cassini radio Doppler data used in the analysis, but after restricting the analysis to a subset of data obtained closest to the moon, he arrived at his old result that Rhea was in hydrostatic equilibrium and had the moment inertia of about 0.4, again implying a homogeneous interior.

text: The book delves into the subject of "The Days Before There Was a Moon", as remembered in tales that Chee Chee the Monkey's grandmother told him when he was little. The story of how the moon was created is closer to science than some of the other fantasy elements of the book. Otho Bludge, the stone-age sculptor, came to be the man on the moon because he was transported on the lump of rock that had broken off the Earth, and became the moon. Alone for many years, the sole human on the Moon, Otho Bludge, weary of rendering his own image as reflected in the water, longed for the sight of another human being. In answer to his longing, he was visited by a vision of Princess Pepiteepa, who poses for him, then fades away.

text: A full moon is the lunar phase that occurs when the Moon is completely illuminated as seen from Earth. This occurs when Earth is located directly between the Sun and the Moon (more exactly, when the ecliptic longitudes of the Sun and Moon differ by 180 degrees). This means that the hemisphere of the Moon that is facing Earth (the near side) is almost fully illuminated by the Sun and appears round (while the far side is almost completely unilluminated). On some occasions at the time of full moon there is also a lunar eclipse so the moon's face appears reddish due to the rayleigh scattering of blue light in Earth's atmosphere.

text: The tidal force produced by a massive object (Moon, hereafter) on a small particle located on or in an extensive body (Earth, hereafter) is the vector difference between the gravitational force exerted by the Moon on the particle, and the gravitational force that would be exerted on the particle if it were located at the Earth's center of mass. The solar gravitational force on the Earth is on average 179 times stronger than the lunar, but because the Sun is on average 389 times farther from the Earth, its field gradient is weaker. The solar tidal force is 46% as large as the lunar. More precisely, the lunar tidal acceleration (along the Moon–Earth axis, at the Earth's surface) is about 1.1 × 10 g, while the solar tidal acceleration (along the Sun–Earth axis, at the Earth's surface) is about 0.52 × 10 g, where g is the gravitational acceleration at the Earth's surface. Venus has the largest effect of the other planets, at 0.000113 times the solar effect.

text: In contrast, manned vehicles need additional fuel after a lunar landing to enable a return trip back to Earth for the crew. Leaving this massive amount of required Earth-return fuel in lunar orbit until it is used later in the mission is far more efficient than taking such fuel down to the lunar surface in a Moon landing and then hauling it all back into space yet again, working against lunar gravity both ways. Such considerations lead logically to a lunar orbit rendezvous mission profile for a manned Moon landing.

text: The lunar geological timescale (or selenological timescale) divides the history of Earth's Moon into five generally recognized periods: the Copernican, Eratosthenian, Imbrian (Late and Early epochs), Nectarian, and Pre-Nectarian. The boundaries of this time scale are related to large impact events that have modified the lunar surface, changes in crater form that occur through time, and the size-frequency distribution of craters superposed on geological units. The absolute ages for these periods have been constrained by radiometric dating of samples obtained from the lunar surface. However, there is still much debate concerning the ages of certain key events, because correlating lunar regolith samples with geological units on the Moon is difficult, and most lunar radiometric ages have been highly affected by an intense history of bombardment.

text: Herschel was sure that he had found ample evidence of life on the Moon and compared it to the English countryside. He did not refrain himself from theorising that the other planets were populated, with a special interest in Mars, which was in line with most of his contemporary scientists. At Herschel's time, scientists tended to believe in a plurality of civilised worlds, while most religious thinkers referred to unique properties of the earth. Herschel went so far to speculate that the interior of the sun was populated.

text: Cabeus is a lunar crater that is located about  from the south pole of the Moon. At this location the crater is seen obliquely from Earth, and it is almost perpetually in deep shadow due to lack of sunlight. Hence, not much detail can be seen of this crater, even from orbit. Through a telescope, this crater appears near the southern limb of the Moon, to the west of the crater Malapert and to the south-southwest of Newton.

text: Artsimovich is a small lunar impact crater located in the western Mare Imbrium of the Earth's Moon. This is a circular crater forming a cup-shaped excavation in the surface of the lunar mare. To the east is the crater Diophantus and to the northeast lies Delisle. Less than 20 kilometers to the north-northeast is the tiny Fedorov. This crater was identified as Diophantus A before being named by the IAU.

text: One very important feature common in east Hellas are piles of material surrounding cliffs.  The formation is called a lobate debris apron (LDA).  Recently, research with the Shallow Radar on the Mars Reconnaissance Orbiter has provided strong evidence that the LDAs are glaciers that are covered with a thin layer of rocks. Large amounts of water ice are believed to be in the LDAs.  Available evidence strongly suggests that the eastern part of Hellas accumulated snow in the past.  When the tilt (obliquity) of Mars increases the southern ice cap releases large amounts of water vapor.  Climate models predict that when this occurs, water vapor condenses and falls where LDAs are located.  The tilt of the earth changes little because our relatively large moon keeps it stable.  The two tiny Martian moons do not stabilize their planet, so the rotational axis of Mars undergoes large variations.  Lobate debris aprons may be a major source of water for future Mars colonists.  Their major advantage over other sources of Martian water are that they can easily mapped from orbit and they are closer to the equator, where manned missions are more likely to land.

text: A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth. The technical name is the perigee-syzygy of the Earth–Moon–Sun system. The term supermoon is not astronomical, but originated in modern astrology. The association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions, but there is no evidence of such a link.

text: His scientific interests included seismology, meteorology, astrophysics and theoretical physics. He began his career in seismology with his father. In 1913 he developed a new method for locating the hypocenter of an earthquake and gave an independent verification of discontinuity theory put forward by his father. In 1916 he published an idea of the existence of smaller discontinuities in Earth's crust and mantle. He put forward his own theory about the composition and the formation of the Moon, explosive formation of lunar craters and predicted the existence of Moho layer on the Moon. The existence of Moho layer on the Moon was confirmed in 1969 by seismic measurements done by Apollo 11 crew.

text: Craters less than about 30 km in diameter were not mapped except for those that are rayed and those occurring in chains and clusters satellitic to larger craters and basins. These satellitic or secondary craters are not distinguished as to relative age or origin. (However, near the southwest map corner, elongate chains are radial to their parent crater Valmiki). In general, secondary craters appear topographically fresher and occur closer to their primary sources than do their lunar counterparts. This effect is probably because the higher gravity field on Mercury compared to the Moon has resulted in higher impact velocities for crater ejecta (Scott, 1977).

text: Using the simplified model where the orbit of the Moon around the Earth is circular, Schwaniger found that there exists a free-return trajectory in the plane of the orbit of the Moon which is periodic: after returning to low altitude above the Earth (the perigee radius is a parameter, typically 6555 km) the spacecraft would return to the Moon, etc. This periodic trajectory is counter-rotational (it goes from east to west when near the earth). It has a period of about 650 hours (compare with a sidereal month, which is 655.7 hours, or 27.3 days). Considering the trajectory in an inertial (non-rotating) frame of reference, the perigee occurs directly under the moon when the moon is on one side of the earth. Speed at perigee is about 10.91 km/s. After three days it reaches the moon's orbit, but now more or less on the opposite side of the earth from the moon. After a few more days the craft reaches ifs (first) apogee and begins to fall back toward the earth. But then the moon comes along and attracts the craft. The craft passes on the near side of the moon at a radius of 2150 km (410 km above the surface) and is thrown back outwards where it reaches a second apogee. It then falls back toward the earth, goes around to the first side, and goes through another perigee close to where the first perigee had taken place.

text: The gravitational force between the Sun and moon induces the precession in Earth's orbit, which is the major cause of the climate oscillation of Earth that has a period of 19,000 to 23,000 years. It follows that changes in Earth's orbital parameters (e.g., orbital inclination, the angle between Earth's rotation axis and its plane of orbit) is important to the study of Earth's climate, in particular to the study of past ice ages. (See also nodal precession. For precession of the lunar orbit see lunar precession).

text: Earth's Moon probably formed out of material splashed into orbit by the impact of a large body into the early Earth. Differentiation on Earth had probably already separated many lighter materials toward the surface, so that the impact removed a disproportionate amount of silicate material from Earth, and left the majority of the dense metal behind. The Moon's density is substantially less than that of Earth, due to its lack of a large iron core.

text: The contrasting elements of the blood described in line 3 and the "purity" of the unclouded moon in line 30 represents a major theme of the work. The moon's surface appears unchanging and contrasts with the earth that has been stained with the blood of men as the result of "arrogant power". As the poem speaks of the pristine nature of the moon's surface in the third stanza Helen Vendler suggests that it broadens the contrast between the two surfaces to highlight the difference between "the mortal and the incorruptible". However, she also states that the poem's theme of life and death shifts focus in the final stanza as the poet discusses the trapped butterflies, which "brings into view the pathos of life, rather than its violence".

text: In 1959 the Soviets obtained the first images of the far side of the Moon, never previously visible to humans. The U.S. exploration of the Moon began with the Ranger 4 impactor in 1962. Starting in 1966 the Soviets successfully deployed a number of landers to the Moon which were able to obtain data directly from the Moon's surface; just four months later, Surveyor 1 marked the debut of a successful series of U.S. landers. The Soviet unmanned missions culminated in the Lunokhod program in the early 1970s, which included the first unmanned rovers and also successfully brought lunar soil samples to Earth for study. This marked the first (and to date the only) automated return of extraterrestrial soil samples to Earth. Unmanned exploration of the Moon continues with various nations periodically deploying lunar orbiters, and in 2008 the Indian Moon Impact Probe.

text: Smooth plains are widespread flat areas resembling the lunar maria of the Moon, which fill depressions of various sizes. A prime example of a smooth plain is the one in which fills a wide ring surrounding the Caloris Basin, the largest impact basin on Mercury. However, a noticeable difference between the lunar maria of the Moon and the smooth plains of Mercury is that these smooth plains have the same albedo, or properties, as the bordering inter-crater plains. Even with a lack of volcanic features, it is still believed that smooth plains are of volcanic origin.

text: The central peaks of large lunar craters may contain material that rose from as far 19 kilometers beneath the surface when the peaks formed by rebound of the compressed rock under the crater. Material moved from the interior of craters is piled in their rims. These and other processes make possibly novel concentrations of minerals accessible to future prospectors from lunar colonies.

text: Donna is a tiny lunar crater on the near side of the Moon. It is located in the eastern half of the Mare Tranquillitatis, at the summit of the lunar dome Omega (ω) Cauchy. As such domes are thought to be volcanic in nature, it appears likely that this crater was created by an eruption. This is in contrast to most lunar craters, which are now believed to be created by impacts. This crater is sufficiently small that it requires a large telescope to resolve.

text: This irregular area contains a number of smaller depressions that have become covered in flows of basaltic lavas. These form what are essentially miniature lunar maria. They are clustered near the southern borders of the area, and fill much of the terrain between Mare Vaporum and the Montes Haemus. These mare-like features are generally irregular in shape, and many are joined together through gaps between the more rugged islands of continental terrain.

text: During new and  full moons, when the river is relatively less deep and the ocean tide is high, water flows in from the Atlantic, rather than the other way around. As river and ocean collide, the Amazon’s flow reverses and a water bulge speeds upstream with incredible force, forming a tidal bore with rumbling noise. The tidal phenomenon is best observed on biannual equinoxes in September and March. On an equinox, when the Moon and Sun fall into alignment with the Earth, their gravitational pull is combined, bringing the Pororoca to its peak.

text: Significant barriers to more universal acceptance of this technology differ in their extent for different parts of the world but generally include: lack of awareness, a limited supply of prefabricated UDDT components and a lack of interest in financing any sanitation services for the non-sewered portions of urban settlements. Existing, affordable piped water supply and sanitary sewer infrastructure may also be an impediment to widespread adoption of UDDTs as their existence not only removes two of the main drivers for UDDTs but also represents a significant public investment. This can restrict efforts to switch to new toilet types and sanitation systems.

text: The Lunar far side lacks direct communication with Earth, though a communication satellite at the  Lagrangian point, or a network of orbiting satellites, could enable communication between the far side of the Moon and Earth. The far side is also a good location for a large radio telescope because it is well shielded from the Earth. Due to the lack of atmosphere, the location is also suitable for an array of optical telescopes, similar to the Very Large Telescope in Chile. To date, there has been no ground exploration of the far side.

text: J. Herschel is large lunar crater of the variety termed a walled plain. It is located in the northern part of the Moon's surface, and so appears foreshortened when viewed from the Earth. The southeastern rim of J. Herschel forms part of the edge of the Mare Frigoris lunar mare. To the northwest is the crater Anaximander. Bordering the northern rim is a large, unnamed lunar plain. Just to the south is the small crater Horrebow.

text: During a total solar eclipse, the Moon's shadow covers only a small fraction of the Earth. The Earth continues to receive at least 92 percent of the amount of sunlight it receives without an eclipse – more if the penumbra of the Moon's shadow partly misses the Earth. Seen from the Moon, the Earth during a total solar eclipse is mostly brilliantly illuminated, with only a small dark patch showing the Moon's shadow. The brilliantly-lit Earth reflects a lot of light to the Moon. If the corona of the eclipsed Sun were not present, the Moon, illuminated by earthlight, would be easily visible from Earth. This would be essentially the same as the earthshine which can frequently be seen when the Moon's phase is a narrow crescent. In reality, the corona, though much less brilliant than the Sun's photosphere, is much brighter than the Moon illuminated by earthlight. Therefore, by contrast, the Moon during a total solar eclipse appears to be black, with the corona surrounding it.

text: Gioia is a lunar crater that is located in the vicinity of the north pole of the Moon. It is named after the Italian inventor Flavio Gioia. As it lies so close to the northern limb, it is viewed nearly from the edge making difficult to observe from the Earth. The crater is attached to the southern rim of the larger Byrd, a formation with low walls. To the south-southeast is the crater Main.

text: The Exploration Systems Architecture Study that followed the Vision for Space Exploration of 2004 recommended the development of a new class of vehicles that have similar capabilities to their Apollo predecessors with several key differences.  In part to retain some of the Space Shuttle program workforce and ground infrastructure, the launch vehicles were to use Shuttle-derived technologies.  Secondly, rather than launching the crew and cargo on the same rocket, the smaller Ares I was to launch the crew with the larger Ares V to handle the heavier cargo.  The two payloads were to rendezvous in low Earth orbit and then head to the Moon from there.   The Apollo Lunar Module could not carry enough fuel to reach the polar regions of the Moon but the Altair lunar lander was intended to access any part of the Moon.  While the Altair and surface systems would have been equally necessary for Project Constellation to reach fruition, the focus was on developing the Orion spacecraft to shorten the gap in US access to orbit following the retirement of the Space Shuttle in 2010.

text: Hygiene in ancient Rome was not ideal for combatting diseases. Their sewer system, praised for its longevity, had many flaws. As Water History’s Roger Hanson explains, street drainage and sewage flowed through the same pipes, which led to sewage openings on the streets. Also, since most sewer systems were privately owned, they were also privately maintained and in turn neglected. Instead, citizens would turn to their latrines; if they lived on anything but the ground floor they would even throw their excrement onto the street. This led to exposure of sewage to flies, dogs, and bacteria, all of which helped spread disease among Romans.

text: Due to the landing site restrictions that resulted from constraining the launch to a free return that flew by the Moon, subsequent Apollo missions, starting with Apollo 12 and including the ill-fated Apollo 13, used a hybrid trajectory that launched to a highly elliptical Earth orbit that fell short of the Moon with effectively a free return to the atmospheric entry corridor. They then performed a mid-course maneuver to change to a trans-Lunar trajectory that was not a free return. This retained the safety characteristics of being on a free return upon launch, and only departed from free return once the systems were checked out and the lunar module was docked with the command module, providing back-up maneuver capabilities.  In fact, within hours after the accident, Apollo 13 used the lunar module to maneuver from its planned trajectory to a free-return trajectory. Apollo 13 was the only Apollo mission to actually turn around the Moon in a free-return trajectory (however, two hours after perilune, propulsion was applied to speed the return to Earth by 10 hours and move the landing spot from the Indian Ocean to the Pacific Ocean).

text: Graha (from Sanskrit ग्रह gráha—seizing, laying hold of, holding) is a 'cosmic influencer' on the living beings of mother Bhumidevi (Earth). In Hindu astrology, the Navagraha (Sanskrit: नवग्रह, nine seizers or nine influencers) are some of these major influencers.  All the navagraha have relative movement with respect to the background of fixed stars in the zodiac. This includes the planets:  Mars, Mercury, Jupiter, Venus, and Saturn, the Sun, the Moon, as well as positions in the sky, Rahu (north or ascending lunar node) and Ketu (south or descending lunar node).

text: This experiment used radar to study the Moon's surface and interior. Radar waves with wavelengths between 2 and 60 meters (frequencies of 5, 15, and 150 MHz) were transmitted through a series of antennas near the back of the Apollo Service Module. After the waves were reflected by the Moon, they were received using the same antennas and the data was recorded on film for analysis on Earth. The primary purpose of this experiment was to "see" into the upper 2 kilometers of the Moon's crust in a manner somewhat analogous to using seismic waves to study the internal structure of the Moon. This was possible because very long radar wavelengths were used and because the Moon is very dry, which allowed the radar waves to penetrate much deeper into the Moon than would have been possible if water were present in lunar rocks. (A radar experiment on the space shuttle has been similarly used to map ancient river valleys beneath the Sahara Desert.) This experiment also provided very precise information about the Moon's topography. In addition to studying the Moon, the experiment also measured radio emissions from the Milky Way Galaxy.

text: Considering the Earth–Moon system as a binary planet, its centre of gravity is within Earth, about  or 72.6% of the Earth's radius from the centre of the Earth. This centre of gravity remains on the line between the centres of the earth and Moon as the Earth completes its diurnal rotation. The path of the Earth–Moon system in its solar orbit is defined as the movement of this mutual centre of gravity around the sun. Consequently, Earth's centre veers inside and outside the solar orbital path during each synodic month as the Moon moves in its orbit around the common centre of gravity.

text: Due to the low viscosity of most lunar lava, volcanic mountains were seldom created. Instead, basaltic lava flooded large areas, which became lunar maria. Shield volcanoes are known from a few areas on the Moon; they are called lunar domes. Some areas of the Moon are covered with a usually dark coating, which is interpreted as pyroclastic deposits. Sometimes they form a dark halo around rilles. See also:

text: Solar and lunar eclipses were scientifically explained by Aryabhata. He states that the Moon and planets shine by reflected sunlight. Instead of the prevailing cosmogony in which eclipses were caused by Rahu and Ketu (identified as the pseudo-planetary lunar nodes), he explains eclipses in terms of shadows cast by and falling on Earth. Thus, the lunar eclipse occurs when the moon enters into the Earth's shadow (verse gola.37). He discusses at length the size and extent of the Earth's shadow (verses gola.38–48) and then provides the computation and the size of the eclipsed part during an eclipse. Later Indian astronomers improved on the calculations, but Aryabhata's methods provided the core. His computational paradigm was so accurate that 18th-century scientist Guillaume Le Gentil, during a visit to Pondicherry, India, found the Indian computations of the duration of the lunar eclipse of 30 August 1765 to be short by 41 seconds, whereas his charts (by Tobias Mayer, 1752) were long by 68 seconds.

text: There has been historical controversy over whether features on the Moon's surface change over time. Today, many of these claims are thought to be illusory, resulting from observation under different lighting conditions, poor astronomical seeing, or inadequate drawings. However, outgassing does occasionally occur, and could be responsible for a minor percentage of the reported lunar transient phenomena. Recently, it has been suggested that a roughly  diameter region of the lunar surface was modified by a gas release event about a million years ago. The Moon's appearance, like that of the Sun, can be affected by Earth's atmosphere: common effects are a 22° halo ring formed when the Moon's light is refracted through the ice crystals of high cirrostratus cloud, and smaller coronal rings when the Moon is seen through thin clouds.

text: There are several different periods associated with the lunar orbit. The sidereal month is the time it takes to make one complete orbit around Earth with respect to the fixed stars. It is about 27.32 days. The synodic month is the time it takes the Moon to reach the same visual phase. This varies notably throughout the year, but averages around 29.53 days. The synodic period is longer than the sidereal period because the Earth–Moon system moves in its orbit around the Sun during each sidereal month, hence a longer period is required to achieve a similar alignment of Earth, the Sun, and the Moon. The anomalistic month is the time between perigees and is about 27.55 days. The Earth–Moon separation determines the strength of the lunar tide raising force.

text: The lunar phase or phase of the moon is the shape of the illuminated (sunlit) portion of the Moon as seen by an observer on Earth.  The lunar phases change cyclically as the Moon orbits the Earth, according to the changing positions of the  Moon and Sun relative to the Earth. The Moon's rotation is tidally locked by the Earth's gravity, therefore the same lunar surface always faces Earth. This face is variously sunlit depending on the position of the Moon in its orbit. Therefore, the portion of this hemisphere that is visible to an observer on Earth can vary from about 100% (full moon) to 0% (new moon). The lunar terminator is the boundary between the illuminated and darkened hemispheres. Each of the four "intermediate" lunar phases (see below) is roughly seven days (~7.4 days) but this varies slightly due to the elliptical shape of the Moon's orbit. Aside from some craters near the lunar poles such as Shoemaker, all parts of the Moon see around 14.77 days of sunlight, followed by 14.77 days of "night". (The side of the Moon facing away from the Earth is sometimes called the "dark side", which is a misnomer.

text: Gliese 876 b currently lies beyond the outer edge of the habitable zone but because Gliese 876 is a slowly evolving main-sequence red dwarf its habitable zone is very slowly moving outwards and will continue to do so for trillions of years. Therefore, Gliese 876 b will, in trillions of years time, lie inside Gliese 876's habitable zone, as defined by the ability of an Earth-mass planet to retain liquid water at its surface, and remain there for at least 4.6 billion years. While the prospects for life on a gas giant are unknown, large moons may be able to support a habitable environment. Models of tidal interactions between a hypothetical moon, the planet and the star suggest that large moons should be able to survive in orbit around Gliese 876 b for the lifetime of the system. On the other hand, it is unclear whether such moons could form in the first place. However, the large mass of the gas giant may make it more likely for larger moons to form.

text: Because the Earth's tides are ultimately due to gravitational interaction with the Moon and Sun and the Earth's rotation, tidal power is practically inexhaustible and classified as a renewable energy resource. Movement of tides causes a loss of mechanical energy in the Earth–Moon system: this is a result of pumping of water through natural restrictions around coastlines and consequent viscous dissipation at the seabed and in turbulence. This loss of energy has caused the rotation of the Earth to slow in the 4.5 billion years since its formation. During the last 620 million years the period of rotation of the earth (length of a day) has increased from 21.9 hours to 24 hours; in this period the Earth has lost 17% of its rotational energy. While tidal power will take additional energy from the system, the effect is negligible and would only be noticed over millions of years.

text: The Moon's orbit around the Earth is elliptical, which causes the Moon to be closer to the Earth and farther away at different times.  The Moon and the Sun are aligned every two weeks, which results in spring tides – tides that are 20% higher than normal.  During the period of the new moon, the Moon and Sun are on the same side of the Earth, so the high tides or bulges produced independently by each reinforce each other (and has nothing to do with the season called spring).  Tides of maximum height and depression produced during this period are known as spring tide.  Even higher than a normal spring tide are the perigean tides. Perigean spring tides can produce unusually intense flooding along the coastal regions. Low amplitude tides are known as neap tides.

text: Almost all maria are on the near side of the Moon, and cover 31% of the surface of the near side, compared with 2% of the far side. This is thought to be due to a concentration of heat-producing elements under the crust on the near side, seen on geochemical maps obtained by Lunar Prospectors gamma-ray spectrometer, which would have caused the underlying mantle to heat up, partially melt, rise to the surface and erupt. Most of the Moon's mare basalts erupted during the Imbrian period, 3.0–3.5 billion years ago, although some radiometrically dated samples are as old as 4.2 billion years. Until recently, the youngest eruptions, dated by crater counting, appeared to have been only 1.2 billion years ago. In 2006, a study of Ina, a tiny depression in Lacus Felicitatis, found jagged, relatively dust-free features that, due to the lack of erosion by infalling debris, appeared to be only 2 million years old. Moonquakes and releases of gas also indicate some continued lunar activity. In 2014 NASA announced "widespread evidence of young lunar volcanism" at 70 irregular mare patches identified by the Lunar Reconnaissance Orbiter, some less than 50 million years old. This raises the possibility of a much warmer lunar mantle than previously believed, at least on the near side where the deep crust is substantially warmer due to the greater concentration of radioactive elements. Just prior to this, evidence has been presented for 2–10 million years younger basaltic volcanism inside Lowell crater, Orientale basin, located in the transition zone between the near and far sides of the Moon. An initially hotter mantle and/or local enrichment of heat-producing elements in the mantle could be responsible for prolonged activities also on the far side in the Orientale basin.

text: The Moon is the primary source of the gravitational forces that cause the tides. The proximity of the Moon to the Earth has an effect on the range of the tides at any given time. In each of its 28-day elliptical orbits, the Moon reaches a perigee, its closest point of approach to the Earth. During these periods, there is a slight increase in the average range of tides. The increases in the range of the tides is seen by a slightly higher than average high tide, as well as a slightly lower than average low tide. Additionally, twice each month, around the times of the new moon and full moon, when the Earth, Sun, and Moon are nearly in line, there is an increase in the average range of the tides. These are called "spring tides". Three or four times a year, the occurrence of a new or full moon will coincide with the perigee of the Moon, which Fergus Wood has termed the "perigean spring tides".

text: Lunar materials may also be valuable for other uses.  It has also been proposed to use lunar regolith as a general construction material, through processing techniques such as sintering, hot-pressing, liquification, and the cast basalt method. Cast basalt is used on Earth for construction of, for example, pipes where a high resistance to abrasion is required. Cast basalt has a very high hardness of 8 Mohs (diamond is 10 Mohs) but is also susceptible to mechanical impact and thermal shock which could be a problem on the Moon.

text: The Apollo 15 subsatellite (PFS-1) was a small satellite released into lunar orbit from the SIM bay. Its main objectives were to study the plasma, particle, and magnetic field environment of the Moon and map the lunar gravity field. Specifically, it measured plasma and energetic particle intensities and vector magnetic fields, and facilitated tracking of the satellite velocity to high precision. A basic requirement was that the satellite acquire fields and particle data everywhere on the orbit around the Moon.  The Moon's roughly circular orbit about the Earth at ~380,000 km (60 Earth radii) carried the subsatellite into both interplanetary space and various regions of the Earth's magnetosphere. The satellite orbited the Moon and returned data from August 4, 1971 until January 1973.

text: Gamma (denoted as γ) of an eclipse describes how centrally the shadow of the Moon or Earth strikes the other. The distance, when the axis of the shadow cone passes closest to Earth or Moon's center, is stated as a fraction of the equatorial radius of the Earth. The sign of gamma defines, for a solar eclipse, if the axis of the shadow passes north or south of the center of the Earth; a positive value means north. For a lunar eclipse it defines whether the axis of the Earth's shadow passes north or south of the Moon; a positive value means south. For solar eclipses the Earth is defined as that half which is exposed to the Sun (this changes with the seasons and is not related directly to the Earth's poles or equator, thus the Earth's center is wherever the Sun is directly overhead).

text: High precision Lunar Laser Ranging (LLR) started soon after the Apollo 11 astronauts left the first retroreflector on the Moon. Additional reflectors were left by the Apollo 14 and Apollo 15 astronauts, and two French-built reflector arrays were placed on the Moon by the Soviet Luna 17 (Lunokhod 1) and Luna 21 (Lunokhod 2) lunar rover missions. Over the years since, many groups and experiments have used this technique to study the behavior of the Earth-Moon system, investigating gravitational and other effects.

text: Due to its proximity and familiarity, Earth's Moon is discussed as a target for colonization. It has the benefits of proximity to Earth and lower escape velocity, allowing for easier exchange of goods and services. A drawback of the Moon is its low abundance of volatiles necessary for life such as hydrogen, nitrogen, and carbon. Water-ice deposits that exist in some polar craters could serve as a source for these elements. An alternative solution is to bring hydrogen from near-Earth asteroids and combine it with oxygen extracted from lunar rock.

text: Using telescopes on Earth, the reflectors on the Moon, and accurate timing of laser pulses, by the early 2000s scientists could measure and predict the orbit of the Moon to an accuracy of a few centimeters. This already impressive accuracy (the Moon is typically about 385,000 km away) provides the best known test of many aspects of our theories of gravity. APOLLO improves this even further, measuring the distance between the Moon to an accuracy of a few millimeters. Using this information, scientists will be able to further test various aspects of gravity: do the Earth and the Moon react the same to gravity despite their different compositions?  Does the energy content of the Earth and the Moon react to gravity in the same way as Einstein predicts?  In general, does Einstein's General Relativity correctly predict the motion of the Moon, or are new theories required?

text: Lunar water is water that is present on the Moon. Liquid water cannot persist at the Moon's surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space. However, scientists have since the 1960s conjectured that water ice could survive in cold, permanently shadowed craters at the Moon's poles. Water molecules are also detected in the thin layer of gases above the lunar surface.

text: Purkyně is a lunar impact crater that lies just beyond the eastern limb of the Moon, on the far side from the Earth. When conditions of libration and sunlight allow, this crater can be viewed from the Earth, although it is seen from a very low angle and not much detail can be seen. This crater lies just to the west of the larger crater Wyld, and to the north-northwest of the even bigger Hirayama. To the west and northwest of Purkyně is the Mare Smythii.

text: Between 1972 and 1977, seismometers installed on the Moon by the Apollo missions recorded moonquakes.  The Moon was described as "ringing like a bell" during some of those quakes, specifically the shallow ones.  This phrase was brought to popular attention in March 1970, in an article in Popular Science.  When Apollo 12 deliberately crashed the Ascent Stage of its Lunar Module onto the Moon’s surface, it was claimed that the Moon rang like a bell for an hour, leading to arguments that it must be hollow like a bell.  Lunar seismology experiments since then have shown that the lunar body has shallow moonquakes that act differently from quakes on Earth, due to differences in texture, type and density of the planetary strata, but there is no evidence of any large empty space inside the body.

text: Hermite is a lunar impact crater located along the northern lunar limb, close to the north pole of the Moon. It was first discovered in 1964. To the west is the crater Rozhdestvenskiy, and to the south are Lovelace and Sylvester. Grignard is located directly adjacent to the Southwest. From the Earth this crater is viewed nearly from the side, and it is illuminated by oblique sunlight.

text: For a total solar eclipse to happen, the ratio of the apparent diameters of the Moon and of the Sun must be 1.0 or bigger and the three celestial bodies (Sun, Earth and Moon) must be aligned centrally enough. When that is the case, the Moon's disk covers the Sun's disk in the sky completely. The path of totality (i.e. of the travelling shadow of the Moon cutting off all direct sunlight from reaching the Earth's surface) is a relatively narrow strip, at most a few hundreds of kilometers across.

text: The Malta Apollo 17 lunar sample display commemorative style plaque (10 by 14 inches) consists of one "moon rock" particle specimen that was cut from lunar basalt 70017 and a Maltese flag. The basalt 70017 was collected by Apollo 17 astronaut Harrison Schmitt on the moon in 1972. Once lunar basalt 70017 was brought back to earth from the moon, the basalt moon rock was cut up into small fragments of approximately 1 gram. The specimen was encased in a plastic ball and mounted on the wooden plaque along with the Maltese flag which had been taken to the moon and back by the crew of Apollo 17. The plaque was then distributed in 1973 by President Nixon to the country of Malta, as he did that year to the other 134 countries of the world (the same countries previously for the Apollo 11 plaque display gifts) and again to all 50 states of the United States. This was done as a goodwill gesture to promote peace and harmony.

text: Several mechanisms have been proposed for the Moon's formation 4.53 billion years ago, and some 30–50 million years after the origin of the Solar System. Recent research presented by Rick Carlson indicates a slightly lower age of between 4.40 and 4.45 billion years. These mechanisms included the fission of the Moon from Earth's crust through centrifugal force (which would require too great an initial spin of Earth), the gravitational capture of a pre-formed Moon (which would require an unfeasibly extended atmosphere of Earth to dissipate the energy of the passing Moon), and the co-formation of Earth and the Moon together in the primordial accretion disk (which does not explain the depletion of metals in the Moon). These hypotheses also cannot account for the high angular momentum of the Earth–Moon system.

text: The album's recording sessions took place from December 1996 to January 1997 at Studio Litho in Seattle, Washington. Studio Litho is owned by guitarist Stone Gossard. The band worked with producer Nick DiDia. The album was mixed by DiDia and Brendan O'Brien. The album featured a more polished sound compared with the band's debut album, Shame. Interiors was met with poor sales, however the band saw its cult audience expand. The lead single from Interiors, "The Day Brings", features Mike McCready from Pearl Jam on lead guitar. The album charted at number 30 on Billboards Top Heatseekers chart. Tom Moon of Rolling Stone said that "what's most notable about Interiors...is the pure pop focus of these nuanced compositions." A music video was made for the song "The Day Brings". Interiors was accompanied by a tour in the United States and Canada in 1997, as well as a small tour in Australia and New Zealand in 1998.

text: Eclipses can only occur when the Sun, Earth, and Moon are all in a straight line (termed "syzygy"). Solar eclipses occur at new moon, when the Moon is between the Sun and Earth. In contrast, lunar eclipses occur at full moon, when Earth is between the Sun and Moon. The apparent size of the Moon is roughly the same as that of the Sun, with both being viewed at close to one-half a degree wide. The Sun is much larger than the Moon but it is the precise vastly greater distance that gives it the same apparent size as the much closer and much smaller Moon from the perspective of Earth. The variations in apparent size, due to the non-circular orbits, are nearly the same as well, though occurring in different cycles. This makes possible both total (with the Moon appearing larger than the Sun) and annular (with the Moon appearing smaller than the Sun) solar eclipses. In a total eclipse, the Moon completely covers the disc of the Sun and the solar corona becomes visible to the naked eye. Because the distance between the Moon and Earth is very slowly increasing over time, the angular diameter of the Moon is decreasing. Also, as it evolves toward becoming a red giant, the size of the Sun, and its apparent diameter in the sky, are slowly increasing. The combination of these two changes means that hundreds of millions of years ago, the Moon would always completely cover the Sun on solar eclipses, and no annular eclipses were possible. Likewise, hundreds of millions of years in the future, the Moon will no longer cover the Sun completely, and total solar eclipses will not occur.

text: A lunar eclipse occurs when the Moon passes within Earth's umbra (shadow). As the eclipse begins, the Earth's shadow first darkens the Moon slightly.  Then, the shadow begins to "cover" part of the Moon, turning it a dark red-brown color (typically - the color can vary based on atmospheric conditions).  The Moon appears to be reddish because of Rayleigh scattering (the same effect that causes sunsets to appear reddish) and the refraction of that light by the Earth's atmosphere into its umbra.The following simulation shows the approximate appearance of the Moon passing through the earth's shadow. The Moon's brightness is exaggerated within the umbral shadow. The southern portion of the Moon was closest to the center of the shadow, making it darkest, and most red in appearance.

text: The EPIC science team plans to upload 12 new color images per day on their website. The color balance has been adjusted to approximate an image that could be seen with the average human eye. In addition to images, scientific information will be uploaded as it becomes available after in-flight calibration is complete. The science information will be ozone and aerosol amounts, cloud reflectivity, cloud height, and vegetation information.  The EPIC instrument views the Earth from sunrise in the west to sunset in the east 12 to 13 times per day as the Earth rotates at 15 degrees of longitude per hour. Clearly visible are storms forming over the Atlantic and Pacific Oceans, major slowly moving "cloud rivers", dust aerosol plumes from Africa, the sun's reflection in the oceans, ship exhaust tracks in the clouds, rivers and lakes, and the variegated land surface patterns especially in the African deserts. The spatial resolution of the color images is about 10 km, and the resolution of the science products will be about 20 km. Once every three months, lunar images are obtained that are the same as those viewed from Earth during our full Moon. On occasion, the other side of the Moon will appear in the Earth images as the Moon crosses in front of the Earth.

This may be economical for short missions of spacecraft, but it is not the most viable solution when dealing with the life support systems of a long-term craft (such as a generation ship) or a settlement.

text: The Moon's appearance is considerably more complex. Its motion, like the Sun, is between two limits — known as lunistices rather than solstices. However, its travel between lunistices is considerably faster. It takes a sidereal month to complete its cycle rather than the year-long trek of the Sun. This is further complicated as the lunistices marking the limits of the Moon's movement move on an 18.6 year cycle. For slightly over nine years the extreme limits of the moon are outside the range of sunrise. For the remaining half of the cycle the Moon never exceeds the limits of the range of sunrise. However, much lunar observation was concerned with the phase of the Moon. The cycle from one New Moon to the next runs on an entirely different cycle, the Synodic month. Thus when examining sites for lunar significance the data can appear sparse due the extremely variable nature of the moon. See Moon for more details.

text: The Moon's orbit around the Earth is an ellipse, as is the Earth's orbit around the Sun. The apparent sizes of the Sun and Moon therefore vary. The magnitude of an eclipse is the ratio of the apparent size of the Moon to the apparent size of the Sun during an eclipse. An eclipse that occurs when the Moon is near its closest distance to Earth (i.e., near its perigee) can be a total eclipse because the Moon will appear to be large enough to completely cover the Sun's bright disk or photosphere; a total eclipse has a magnitude greater than 1. Conversely, an eclipse that occurs when the Moon is near its farthest distance from Earth (i.e., near its apogee) can only be an annular eclipse because the Moon will appear to be slightly smaller than the Sun; the magnitude of an annular eclipse is less than 1. Slightly more solar eclipses are annular than total because, on average, the Moon lies too far from Earth to cover the Sun completely. A hybrid eclipse occurs when the magnitude of an eclipse changes during the event from less to greater than one, so the eclipse appears to be total at some locations on Earth and annular at other locations.

text: Gilbert's magnetism was the invisible force that many other natural philosophers, such as Kepler, seized upon, incorrectly, as governing the motions that they observed.  While not attributing magnetism to attraction among the stars, Gilbert pointed out the motion of the skies was due to earth's rotation, and not the rotation of the spheres, 20 years before Galileo (but 57 years after Copernicus who stated it openly in his work "De revolutionibus orbium coelestium" published in 1543 ) (see external reference below). Gilbert made the first attempt to map the surface markings on the Moon in the 1590s. His chart, made without the use of a telescope, showed outlines of dark and light patches on the moon's face. Contrary to most of his contemporaries, Gilbert believed that the light spots on the Moon were water, and the dark spots land.

His chart, made without the use of a telescope, showed outlines of dark and light patches on the moon's face. Contrary to most of his contemporaries, Gilbert believed that the light spots on the Moon were water, and the dark spots land.

text: The most distinctive aspect of the Moon is the contrast between its bright and dark zones. Lighter surfaces are the lunar highlands, which receive the name of terrae (singular terra, from the Latin for Earth), and the darker plains are called maria (singular mare, from the Latin for sea), after Johannes Kepler who introduced the name in the 17th century. The highlands are anorthositic in composition, whereas the maria are basaltic. The maria often coincide with the "lowlands," but it is important to note that the lowlands (such as within the South Pole-Aitken basin) are not always covered by maria. The highlands are older than the visible maria, and hence are more heavily cratered.

text: Former U.S. President George W. Bush, in an address about his Vision for Space Exploration, suggested that the Moon may serve as a cost-effective construction, launching and fueling site for future space exploration missions. As President Bush noted, "(Lunar) soil contains raw materials that might be harvested and processed into rocket fuel or breathable air."  For example, the proposed Ares V heavy-lift rocket system could cost-effectively deliver raw materials from Earth to a docking station, (connected to the lunar elevator as a counterweight,) where future spacecraft could be built and launched, while extracted lunar resources could be shipped up from a base on the Moon's surface, near the elevator's anchoring point. If the elevator was connected somehow to a lunar base built near the Moon's north pole, then workers could also mine the water ice which is known to exist there, providing an ample source of readily accessible water for the crew at the elevator's docking station. Also, since the total energy needed for transit between the Moon and Mars is considerably less than for between Earth and Mars, this concept could lower some of the engineering obstacles to sending humans to Mars.

text: A total solar eclipse will occur on January 27, 2093. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.

text: The proximity of the Moon in relation to Earth and Earth in relation to the Sun also has an effect on tidal ranges.  The Moon moves around Earth in an elliptic orbit that takes about 29 days to complete.  The gravitational force is greatest when the Moon is at perigee — closest to Earth — and least when it is at apogee — farthest from Earth — about two weeks after perigee.  The Moon has a larger effect on the tides than the Sun, but the Sun’s position also has an influence on the tides.  Earth moves around the Sun in an elliptic orbit that takes a little over 365 days to complete.  Its gravitational force is greatest when the Earth is at perihelion — closest to the Sun in early January — and least when the Earth is at aphelion — farthest from the Sun in early July.

text: Ginzel is a lunar crater that is located on the far side of the Moon, just beyond the eastern limb. It is named after the Austrian astronomer Friedrich Karl Ginzel.  It lies at the eastern edge of the Mare Marginis, in a region of the surface that is sometimes brought into sight of the Earth due to libration. To the north-northeast of Ginzel is the crater Popov, and Dreyer lies due south.

text: The only natural satellite of earth i.e.moon takes about 27.3 days to make one complete orbit around the earth. The earth orbits around the sun once every 365.2422 days (= earth’s orbital speed of 29.79 km per second). The earth and the moon in 27.3 days have moved as a system about 1/12 of the ways around the sun. This means that from one full moon to the next full moon, the moon must travel 2.2 extra days before it appears full moon. This is due to the curve of the earth’s orbit around the sun. The moon is still making one complete orbit (circle) in 27.3 days. But to line up with the earth and sun to become a full moon again it takes 29.531 days which means 354.372 days per lunar year. This makes a variance of 10.87 days a year between a lunar year and a solar year of 365.2422 days per year. To compensate this difference, the additional mass is been added after every 32.5 months on an average.

text: The heavens and the earth is a set phrase meaning "everything", i.e., the cosmos. This was made up of three levels, the habitable earth in the middle, the heavens above, an underworld below, all surrounded by a watery "ocean" of chaos as the Babylonian Tiamat. The earth itself was a flat disc, surrounded by mountains or sea. Above it was the firmament, a transparent but solid dome resting on the mountains, allowing men to see the blue of the waters above, with "windows" to allow the rain to enter, and containing the sun, moon and stars. The waters extended below the earth, which rested on pillars sunk in the waters, and in the underworld was Sheol, the abode of the dead.

text: At some unspecified date in the near future, an unknown force causes the Moon to shatter into seven pieces. As the shattered remnants of the Moon begin to collide with one another, astronomer and science popularizer "Doc" Dubois Harris calculates that the number of collisions will increase exponentially. A large number of moon fragments will begin entering Earth's atmosphere, forming a "white sky" and blanketing the earth within two years with what he calls a "Hard Rain" of bolides; this will cause the atmosphere to heat to incandescence and oceans to boil away, and make Earth uninhabitable for thousands of years. It is decided to evacuate as many people and resources as possible to a "Cloud Ark" in orbit, including a "swarm" of "arklet" habitats that will be able to avoid the debris from the moon — both to attempt to preserve the human race and to give the remaining doomed inhabitants of Earth something to hope for, to prevent civil disorder from breaking out on earth before its surface is destroyed.Each nation on Earth is invited to choose by lot a small number of young people to become eligible to join the Cloud Ark.

text: A total solar eclipse will occur on September 2, 2035. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.

text: A solar eclipse occurs when the moon passes between the Earth and the sun, casting a shadow on Earth that temporarily obscures part or all of the sun's disc.  Eclipses can occur only when all three bodies are properly aligned.  Partial eclipses, in which only a portion of the sun's surface is obscured, are relatively common due to the width of the moon's outer shadow, or penumbra, which may be several hundred miles wide.  Total eclipses occur when the moon's inner shadow, or umbra, reaches the surface of the earth, completely obscuring the sun over a much narrower portion of the ground.  If the moon is too far away at the time of an eclipse, its umbra may not reach the Earth's surface, and only a partial eclipse will be visible.

Total eclipses occur when the moon's inner shadow, or umbra, reaches the surface of the earth, completely obscuring the sun over a much narrower portion of the ground.  If the moon is too far away at the time of an eclipse, its umbra may not reach the Earth's surface, and only a partial eclipse will be visible.

text: A total solar eclipse occurred on October 23, 1957. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.

text: The diagram (above) for stellar parallax can illustrate lunar parallax as well, if the diagram is taken to be scaled right down and slightly modified. Instead of 'near star', read 'Moon', and instead of taking the circle at the bottom of the diagram to represent the size of the Earth's orbit around the Sun, take it to be the size of the Earth's globe, and of a circle around the Earth's surface. Then, the lunar (horizontal) parallax amounts to the difference in angular position, relative to the background of distant stars, of the Moon as seen from two different viewing positions on the Earth: one of the viewing positions is the place from which the Moon can be seen directly overhead at a given moment (that is, viewed along the vertical line in the diagram); and the other viewing position is a place from which the Moon can be seen on the horizon at the same moment (that is, viewed along one of the diagonal lines, from an Earth-surface position corresponding roughly to one of the blue dots on the modified diagram).

text: The Brazil Apollo 17 lunar sample display commemorative wooden plaque (10 by 14 inches) consists of one "moon rock" particle specimen that was cut from lunar basalt 70017 and a Brazilian flag. The basalt 70017 was collected by Apollo 17 astronaut Harrison Schmitt on the moon in 1972. Once lunar basalt 70017 was brought back to earth from the moon, the basalt moon rock was cut up into small fragments of approximately 1 gram. The specimen was enveloped in a plastic ball and mounted on the wooden plaque along with the Brazilian flag which had been taken to the moon and back by the crew of Apollo 17. The wooden plaque display was then distributed in 1973 by President Richard Nixon to the country of Brazil as he did that year to all the countries of the world and all the states of the United States (the same as for the Apollo 11 plaque display gifts). This was done as a goodwill gesture to promote peace and harmony.

text: After one saros, the Moon will have completed roughly an integer number of lunar orbit cycles and synodic, draconic, and anomalistic periods (241, 223, 242, and 239) and the Earth-Sun-Moon geometry will be nearly identical: the Moon will have the same phase and be at the same node and the same distance from the Earth. In addition, because the saros is close to 18 years in length (about 11 days longer), the earth will be nearly the same distance from the sun, and tilted to it in nearly the same orientation (same season). Given the date of an eclipse, one saros later a nearly identical eclipse can be predicted. During this 18-year period, about 40 other solar and lunar eclipses take place, but with a somewhat different geometry. One saros equaling 18.03 years is not equal to a perfect integer number of lunar orbits (earth revolutions with respect to the fixed stars of 27.32166 days sidereal month), therefore, even though the relative geometry of the Earth-Sun-Moon system will be nearly identical after a saros, the Moon will be in a slightly different position with respect to the stars for each eclipse in a Saros series.  The axis of rotation of the Earth-Moon system exhibits a precession period of 18.59992 years).

text: It is a relatively rare central eclipse where the moon passes in front of the center of the Earth's shadow. It was the "longest and deepest lunar eclipse to be seen in 7 years". In the total lunar eclipse of July 16, 2000 the moon passed within two arc minutes of the center of the Earth's shadow. In comparison, this still very deep eclipse was off-center by over 12 minutes of arc. The next total lunar eclipse of a longer duration was on June 15, 2011.

text: The challenge was to make sense of the apparently irregular wanderings of the planets on the assumption that all heavenly motion is actually circular and uniform in speed.  Why circular?  Because, Plato held, the circle is the most perfect and symmetrical form; therefore circular motion, at uniform speed, was most fitting for celestial bodies.  Aristotle agreed with Plato.  In Aristotle's cosmos, everything has a "natural" tendency to motion that fulfills its inner potential.  For the cosmos' sublunary part (the region below the moon), the natural tendency is to move in a straight line:  downward for earthen things (such as rocks) and water; upward for air and fiery things (such as sparks).  But in the celestial realm things are not composed of earth, water, air or fire, but of a "fifth element", or "quintessence," which is perfect and eternal.  And its natural motion is uniformly circular.  The stars, the sun, the moon and the planets are carried in their orbits by a complicated arrangement of crystalline spheres, all centered around an immobile earth.

text: A total solar eclipse occurred on August 21, 1560. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.

text: Lunar swirls are enigmatic features found across the Moon’s surface, which are characterized by having a high albedo, appearing optically immature (i.e. having the optical characteristics of a relatively young regolith), and (often) having a sinuous shape. Their curvilinear shape is often accentuated by low albedo regions that wind between the bright swirls. They appear to overlay the lunar surface, superposed on top of craters and ejecta deposits, but impart no observable topography. Swirls have been identified on the lunar maria and highlands - they are not associated with a specific lithologic composition. Swirls on the maria are characterized by strong albedo contrasts and complex, sinuous morphology, whereas those on highland terrain appear less prominent and exhibit simpler shapes, such as single loops or diffuse bright spots.

text: The Man in the Moon is made up of various lunar maria (which ones depends on the pareidolic image seen). These vast, flat spots on the moon are called "maria" or "seas" because, for a long time, astronomers believed they were large bodies of water. They are actually large areas formed by lava that covered up old craters and then cooled, becoming smooth, basalt rock.

text: Water from lunar sources, Near Earth Asteroids or Martian moons is thought to be relatively cheap and simple to extract, and gives adequate performance for many manufacturing and material shipping purposes. Separation of water into hydrogen and oxygen can be easily performed in small scale, but some scientists  believe that this will not be performed on any large scale initially due to the large quantity of equipment and electrical energy needed to split water and liquify the resultant gases. Water used in steam rockets gives a specific impulse of about 190 seconds; less than half that of hydrogen/oxygen, but this is adequate for delta-v's that are found between Mars and Earth. Water is useful as a radiation shield and in many chemical processes.

text: However, these hypotheses were all refuted by the late 1960s and early 1970s Apollo lunar missions, which introduced a stream of new scientific evidence; specifically concerning the Moon's composition, its age, and its history. These lines of evidence contradict many predictions made by these earlier models. The rocks brought back from the Moon showed a marked decrease in water relative to rocks elsewhere in the Solar System, and also evidence of an ocean of magma early in its history, indicating that its formation must have produced a great deal of energy. Also, oxygen isotopes in lunar rocks showed a marked similarity to those on Earth, suggesting that they formed at a similar location in the solar nebula. The capture model fails to explain the similarity in these isotopes (if the Moon had originated in another part of the Solar System, those isotopes would have been different), while the co-accretion model cannot adequately explain the loss of water (if the Moon formed in a similar fashion to the Earth, the amount of water trapped in its mineral structure would also be roughly similar). Conversely, the fission model, while it can account for the similarity in chemical composition and the lack of iron in the Moon, cannot adequately explain its high orbital inclination and, in particular, the large amount of angular momentum in the Earth–Moon system, more than any other planet–satellite pair in the Solar System.

text: If the Moon just revolved around the Earth, there would be no way to tell what fraction of the Moon's or the Earth's gravity was caused by each form of mass, since only the total can be measured. However, the orbit of the Moon is also strongly affected by the gravity of the sun—in essence, Earth and Moon are in freefall around the sun. If the energy portion of mass behaves differently from the conventional portion, then the Earth and the Moon will fall differently toward the Sun, and the orbit of the Moon around the Earth will be affected. For example, suppose the energy part of the mass does affect gravity, but does not affect inertia. Then:

text: The Canada Apollo 17 lunar sample display commemorative wooden plaque (10 by 14 inches) consists of one Moon rock particle specimen that was cut from lunar basalt 70017 and a Canadian flag. The basalt 70017 was collected by Apollo 17 astronaut Harrison Schmitt on the Moon in 1972. Once lunar basalt 70017 was brought back to Earth from the Moon, the basalt Moon rock was cut up into small fragments of approximately 1 gram. The specimen was enveloped in a plastic ball and mounted on the wooden plaque along with the Canadian flag which had been taken to the Moon and back by the crew of Apollo 17. The wooden plaque display was then distributed in 1973 by President Richard Nixon to the country of Canada as he did that year to all the countries of the world and all the states of the United States (the same as for the Apollo 11 plaque display gifts). This was done as a goodwill gesture to promote peace and harmony.

text: China has pursued an ambitious program of lunar exploration, beginning with Chang'e 1, which successfully orbited the Moon from 5 November 2007 until its controlled lunar impact on 1 March 2009. In its sixteen-month mission, it obtained a full image map of the Moon. China followed up this success with Chang'e 2 beginning in October 2010, which reached the Moon over twice as fast as Chang'e 1, mapped the Moon at a higher resolution over an eight-month period, then left lunar orbit in favor of an extended stay at the Earth–Sun L2 Lagrangian point, before finally performing a flyby of asteroid 4179 Toutatis on 13 December 2012, and then heading off into deep space. On 14 December 2013, Chang'e 3 improved upon its orbital mission predecessors by landing a lunar lander onto the Moon's surface, which in turn deployed a lunar rover, named Yutu (Chinese: 玉兔; literally "Jade Rabbit"). In so doing, Chang'e 3 made the first lunar soft landing since Luna 24 in 1976, and the first lunar rover mission since Lunokhod 2 in 1973. China intends to launch another rover mission (Chang'e 4) before 2020, followed by a sample return mission (Chang'e 5) soon after.

text: As observed from the Earth, a solar eclipse occurs when the Moon passes in front of the Sun. The type of solar eclipse event depends on the distance of the Moon from the Earth during the event. A total solar eclipse occurs when the Earth intersects the umbra portion of the Moon's shadow. When the umbra does not reach the surface of the Earth, the Sun is only partially occulted, resulting in an annular eclipse. Partial solar eclipses occur when the viewer is inside the penumbra.

text: Chrétien is a lunar crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side. The crater lies in the midpoint between the craters Garavito to the west-southwest and Oresme to the east-northeast, both of these being somewhat smaller than Chrétien.

text: By the late 1890s, American scientist Samuel Pierpoint Langley had attempted to determine the surface temperature of the Moon by measuring infrared radiation leaving the Moon and reaching the Earth. The angle of the Moon in the sky when a scientist took a measurement determined how much  and water vapor the Moon's radiation had to pass through to reach the Earth's surface, resulting in weaker measurements when the Moon was low in the sky.  This result was unsurprising given that scientists had known about infrared radiation absorption for decades.

text: de Gerlache is a lunar crater that is located along the southern limb of the Moon, within a crater diameter of Shackleton at the south pole. From the Earth this crater is seen from the edge, and it lies in perpetual darkness. Thus little or no detail can be seen of this crater, other than the edge of the rim. However, the crater is clearly visible in Earth-based radar images. The crater is roughly circular, with some slight wear. No craters of note overlie the rim, although some formations may be attached to the southern and western edges.

text: In the 2nd century CE, Ptolemy estimated the mean distance of the Sun as  times Earth's radius. To determine this value, Ptolemy started by measuring the Moon's parallax, finding what amounted to a horizontal lunar parallax of 1° 26′, which was much too large. He then derived a maximum lunar distance of 64 Earth radii. Because of cancelling errors in his parallax figure, his theory of the Moon's orbit, and other factors, this figure was approximately correct. He then measured the apparent sizes of the Sun and the Moon and concluded that the apparent diameter of the Sun was equal to the apparent diameter of the Moon at the Moon's greatest distance, and from records of lunar eclipses, he estimated this apparent diameter, as well as the apparent diameter of the shadow cone of Earth traversed by the Moon during a lunar eclipse. Given these data, the distance of the Sun from Earth can be trigonometrically computed to be  Earth radii. This gives a ratio of solar to lunar distance of approximately 19, matching Aristarchus's figure. Although Ptolemy's procedure is theoretically workable, it is very sensitive to small changes in the data, so much so that changing a measurement by a few percent can make the solar distance infinite.

text: The mythical words established the three worlds (water, air and earth) based on the prologue of the Serer genesis provided by A nax. In A leep, it gives the order in which they were created and elaborated on it. A leep posits that, with the words of Roog, the three worlds (the Universe) began to take shape. The first to be created was the deep sea waters (waters of the underworld); the second was air including the high heavens (Kuul na, in Serer) such as the sun, the moon and the stars; and third was earth. However, the Earth was not one of the first primordial worlds to be formed. It will take a long time before the waters and the Earth were separated.

text: Anno 2205 is a futuristic city-building video game similar to Anno 2070, as opposed to the previous installments which feature a historical setting. In the game, players take on the role of a leader from a corporation and must compete against other corporations in developing future technologies. At the beginning of the game, players are tasked to build different metropolises on Earth. Population increases when more buildings are built, and players are tasked to satisfy and fulfill the needs of their citizens. Besides building houses, players must also produce goods and build infrastructures like robot production facilities to maintain economy, where said buildings can be relocated or moved around by players. Similar to SimCity, different parts can be added to buildings to enhance their functions. Upgrading the production structures of these buildings can also improve their efficiency. When citizens' demands were satisfied, they are able to produce more goods. Eventually players are asked to develop and conduct research in arctic regions in order to find cost-efficient ways to launch rockets to the moon and upon completion, players may colonize the moon and build cities inside its craters. Resources of the moon, such as Helium-3, are vital to the development of the cities on earth and can be sent back to earth. Gameplay differs when players are establishing an outpost in the arctic regions or on the moon. In the arctic regions players must manage the heating areas of the outpost. As the moon lacks an atmosphere and features a grimmer environment than Earth, building a city on the moon requires erecting asteroid shields, as well as unique greenhouses to produce food. Anno 2205 also includes a fully functional day and night cycle for different visuals.

text: As a result of the Moon's synchronous rotation, one side of the Moon (the "near side") is permanently turned towards Earth, and the other side, the "far side", mostly cannot be seen from Earth. This means, conversely, that Earth can only be seen from the near side of the Moon and would always be invisible from the far side.If the Moon's rotation were purely synchronous, Earth would not have any noticeable movement in the Moon's sky. However, due to the Moon's libration, Earth does perform a slow and complex wobbling movement. Once a month, as seen from the Moon, Earth traces out an approximate oval of diameter 18°. The exact shape and orientation of this oval depend on one's location on the Moon. As a result, near the boundary of the near and far sides of the Moon, Earth is sometimes below the horizon and sometimes above it.

text: The far side has more visible craters. This was thought to be a result of the effects of lunar lava flows, which cover and obscure craters, rather than a shielding effect from the Earth. NASA calculates that the Earth obscures only about 4 square degrees out of 41,000 square degrees of the sky as seen from the Moon.  "This makes the Earth negligible as a shield for the Moon. . . . It is likely that each side of the Moon has received equal numbers of impacts, but the resurfacing by lava results in fewer craters visible on the near side than the far side, even though the [sic] both sides have received the same number of impacts."

text: Titov is a relatively small lunar impact crater on the far side of the Moon. The most unusual aspect of this crater is that it is located entirely within the Mare Moscoviense, one of the few maria found on the far side of the Moon. It lies to the northwest of the crater Komarov, in the northern half of the mare.  It is named for cosmonaut Gherman Titov, the second person to orbit the Earth.

text: Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as a result of the impact of a large planetoid with the Earth. Some of this object's mass merged with the Earth, significantly altering its internal composition, and a portion was ejected into space. Some of the material survived to form an orbiting moon. More recent potassium isotopic studies suggest that the Moon was formed by a smaller, high-energy, high-angular-momentum giant impact cleaving off a significant portion of the Earth. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.

text: The Moon is gradually receding from Earth into a higher orbit, and calculations suggest that this would continue for about 50 billion years. By that time, Earth and the Moon would be in a mutual spin–orbit resonance or tidal locking, in which the Moon will orbit Earth in about 47 days (currently 27 days), and both the Moon and Earth would rotate around their axes in the same time, always facing each other with the same side. This has already happened to the Moon—the same side always faces Earth—and is also slowly happening to the Earth. However, the slowdown of Earth's rotation is not occurring fast enough for the rotation to lengthen to a month before other effects change the situation: approximately 2.3 billion years from now, the increase of the Sun's radiation will have caused Earth's oceans to evaporate, removing the bulk of the tidal friction and acceleration.

text: Another issue is lunar and Earth isotope comparisons. In 2001, the most precise measurement yet of the isotopic signatures of lunar rocks was published. Surprisingly, the Apollo lunar samples carried an isotopic signature identical to Earth rocks, but different from other Solar system bodies. Because most of the material that went into orbit to form the Moon was thought to come from Theia, this observation was unexpected. In 2007, researchers from Caltech showed that the likelihood of Theia having an identical isotopic signature as the Earth is very small (<1 percent). Published in 2012, an analysis of titanium isotopes in Apollo lunar samples showed that the Moon has the same composition as Earth, which conflicts with the Moon forming far from Earth's orbit.

text: Spaceports have been proposed for locations on the Moon, Mars, orbiting the Earth, at Sun-Earth and Earth-Moon Lagrange points, and at other locations in the solar system.  Human-tended outposts on the Moon or Mars, for example, will be spaceports by definition. The 2012 Space Studies Program of the International Space University studied the economic benefit of a network of spaceports throughout the solar system beginning from Earth and expanding outwardly in phases, within its team project Operations And Service Infrastructure for Space (OASIS). Its analysis claimed that the first phase, placing the "Node 1" spaceport with space tug services in Low Earth Orbit (LEO), would be commercially profitable and reduce transportation costs to geosynchronous orbit by as much as 44% (depending on the launch vehicle).  The second phase would add a Node 2 spaceport on the lunar surface to provide services including lunar ice mining and delivery of rocket propellants back to Node 1.  This would enable lunar surface activities and further reduce transportation costs within and out from cislunar space.  The third phase would add a Node 3 spaceport on the Martian moon Phobos to enable refueling and resupply prior to Mars surface landings, missions beyond Mars, and return trips to Earth.  In addition to propellant mining and refueling, the network of spaceports could provide services such as power storage and distribution, in-space assembly and repair of spacecraft, communications relay, shelter, construction and leasing of infrastructure, maintaining spacecraft positioned for future use, and logistics.

text: In Aristotle's (384–322 BC) description of the universe, the Moon marked the boundary between the spheres of the mutable elements (earth, water, air and fire), and the imperishable stars of aether, an influential philosophy that would dominate for centuries. However, in the , Seleucus of Seleucia correctly theorized that tides were due to the attraction of the Moon, and that their height depends on the Moon's position relative to the Sun. In the same century, Aristarchus computed the size and distance of the Moon from Earth, obtaining a value of about twenty times the radius of Earth for the distance. These figures were greatly improved by Ptolemy (90–168 AD): his values of a mean distance of 59 times Earth's radius and a diameter of 0.292 Earth diameters were close to the correct values of about 60 and 0.273 respectively. Archimedes (287–212 BC) designed a planetarium that could calculate the motions of the Moon and other objects in the Solar System.

text: Cavor's account explains that Selenites exist in thousands of forms and find fulfillment in carrying out the specific social function for which they have been brought up: specialization is the essence of Selenite society. "With knowledge the Selenites grew and changed; mankind stored their knowledge about them and remained brutes—equipped," remarks the Grand Lunar, when he finally meets Cavor and hears about life on Earth. Unfortunately, Cavor reveals humanity's propensity for war; the lunar leader and those listening to the interview are "stricken with amazement".  Bedford infers that it is for this reason that Cavor has been prevented from further broadcasting to Earth. Cavor's transmissions are cut off as he is trying to describe how to make cavorite.  His final fate is unknown, but Bedford is sure that "we shall never… receive another message from the moon".

text: When asked in 1930 what inspired him for A Trip to the Moon, Méliès credited Jules Verne's novels From the Earth to the Moon and Around the Moon. Cinema historians, the mid-20th-century French writer Georges Sadoul first among them, have frequently suggested H. G. Wells's The First Men in the Moon, a French translation of which was published a few months before Méliès made the film, as another likely influence. Sadoul argued that the first half of the film (up to the shooting of the projectile) is derived from Verne and that the second half (the travelers' adventures on and in the moon) is derived from Wells.

text: The effect on a lunar eclipse is quite similar, with a few differences. First, the eclipsed body is the Moon and the eclipsing 'body' is the Earth's shadow. Second, since the Earth's shadow at the Moon's distance always is considerably larger than the Moon, a lunar eclipse can never be annular but is always partial or total. Third, the Earth's shadow has two components: the dark umbra and the much brighter penumbra. A lunar eclipse will have two geometric magnitudes: the umbral magnitude and the penumbral magnitude. If the three bodies are not aligned enough, the Moon does not reach into the Earth's umbra - it may still pass through the Earth's penumbra though, and such an eclipse is called a penumbral eclipse.

text: The Historic England listing for the Half Moon Public House states that, "The proliferation of ornament across the surface of this building gives the whole a sense of vital unity through their sheer number." The Half Moon is also listed by CAMRA as, "A pub with a nationally important historic interior." Only 270 pubs meet CAMRA's exacting criteria and the Half Moon is one of them. The snug bar contains six back-painted mirrors depicting birds and signed by the renowned ‘W. Gibbs & Sons glass decorators’ of Blackfriars. Photos of the pub from the first part of the 20th century, show it to be operated by Barclay Perkins & Co. The rear of the Half Moon comprises both an original element forming a billiards room, and a later addition constructed during the 1930s to convert this area into a snooker room. These two activities are still advertised in the stained glasswork on the outside of the pub.

text: Lallemand is a small lunar impact crater that lies near the western limb of the Moon, in a region where the visibility is affected by libration effects. Because of its location, when viewed from the Earth the crater is viewed nearly from the side, limiting the amount of detail that can be seen. It lies in the northeast part of a mountain range named the Montes Rook that forms a ring around the enormous Mare Orientale impact basin. To the northeast is the Lacus Autumni and to the northwest lies the Lacus Veris, both forming small lunar maria along the sides of the range.

text: The umbra (Latin for "shadow") is the innermost and darkest part of a shadow, where the light source is completely blocked by the occluding body. Such as an opaque object does not let light through it. An observer in the umbra experiences a total eclipse. The umbra of a round body occluding a round light source forms a right circular cone; to a viewer at the cone's apex, the two bodies are equal in apparent size. The distance from the Moon to the apex of its umbra is roughly equal to that between the Moon and Earth.  Because the Earth is 3.7 times wider than the Moon, its umbra extends correspondingly farther, roughly 1.4 million kilometers.

text: There are three types of lunar eclipses: penumbral, when the Moon crosses only the Earth's penumbra; partial, when the Moon crosses partially into the Earth's umbra; and total, when the Moon crosses entirely into the Earth's umbra. Total lunar eclipses pass through all three phases. Even during a total lunar eclipse, however, the Moon is not completely dark. Sunlight refracted through the Earth's atmosphere enters the umbra and provides a faint illumination. Much as in a sunset, the atmosphere tends to more strongly scatter light with shorter wavelengths, so the illumination of the Moon by refracted light has a red hue, thus the phrase 'Blood Moon' is often found in descriptions of such lunar events as far back as eclipses are recorded.

text: Ole Christensen Rømer used an astronomical measurement to make the first quantitative estimate of the speed of light. When measured from Earth, the periods of moons orbiting a distant planet are shorter when the Earth is approaching the planet than when the Earth is receding from it. The distance travelled by light from the planet (or its moon) to Earth is shorter when the Earth is at the point in its orbit that is closest to its planet than when the Earth is at the farthest point in its orbit, the difference in distance being the diameter of the Earth's orbit around the Sun. The observed change in the moon's orbital period is caused by the difference in the time it takes light to traverse the shorter or longer distance. Rømer observed this effect for Jupiter's innermost moon Io and deduced that light takes 22 minutes to cross the diameter of the Earth's orbit.

text: Slocum is a small lunar impact crater in the southeastern part of the Mare Smythii. It lies near the eastern limb of the Moon, and from the Earth this section of the surface is viewed at a very oblique angle. This greatly limits the amount of detail that can be observed. In addition, libration of the Moon in its orbit can cause this area to be completely hidden from Earth. Nearby craters of note include Runge to the west-northwest, Warner to the west-southwest, and Swasey to the south-southeast.

text: Macula (pl. maculae) is the Latin word for 'spot'. It is used in planetary nomenclature to refer to unusually dark areas on the surface of a planet or moon. They are seen on the icy surfaces of Pluto, Jupiter's moon Europa, Saturn's moon Titan, Neptune's moon Triton, and Pluto's moon Charon. The term was adopted for planetary nomenclature when high resolution pictures of Europa revealed unusual new surface features.

text: The tidal accelerations at the surfaces of planets in the Solar System are generally very small. For example, the lunar tidal acceleration at the Earth's surface along the Moon-Earth axis is about 1.1 × 10 g, while the solar tidal acceleration at the Earth's surface along the Sun-Earth axis is about 0.52 × 10 g, where g is the gravitational acceleration at the Earth's surface. Hence the tide-raising force (acceleration) due to the Sun is about 45% of that due to the Moon. The solar tidal acceleration at the Earth's surface was first given by Newton in the Principia.

text: Although no other moons of Earth have been found to date, there are various types of near-Earth objects in 1:1 resonance with it, which are known as quasi-satellites. Quasi-satellites orbit the Sun from the same distance as a planet, rather than the planet itself. Their orbits are unstable, and will fall into other resonances or be kicked into other orbits over thousands of years. Quasi-satellites of Earth include , ,, , , , and 3753 Cruithne. Cruithne, discovered in 1986, orbits the Sun in an elliptical orbit but appears to have a horseshoe orbit when viewed from Earth. Some went as far to nickname Cruithne "Earth's second moon".

text: When the Sun and Moon are aligned on the same side of the Earth, the moon is "new", and the side of the Moon facing Earth is not illuminated by the Sun. As the moon waxes (the amount of illuminated surface as seen from Earth is increasing), the lunar phases progress through new moon, crescent moon, first-quarter moon, gibbous moon, and full moon. The moon is then said to wane as it passes through the gibbous moon, third-quarter moon, crescent moon and back to new moon. The terms "old moon" and "new moon" are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the sun and begins to wax, at which point it becomes new again. Half moon is often used to mean the first- and third-quarter moons, while the term 'quarter' refers to the extent of the moon's cycle around the Earth, not its shape.

answers: attraction to the Moon

text: While gravitation causes acceleration and movement of the Earth's fluid oceans, gravitational coupling between the Moon and Earth's solid body is mostly elastic and plastic. The result is a further tidal effect of the Moon on the Earth that causes a bulge of the solid portion of the Earth nearest the Moon that acts as a torque in opposition to the Earth's rotation. This "drains" angular momentum and rotational kinetic energy from Earth's spin, slowing the Earth's rotation. That angular momentum, lost from the Earth, is transferred to the Moon in a process (confusingly known as tidal acceleration), which lifts the Moon into a higher orbit and results in its lower orbital speed about the Earth. Thus the distance between Earth and Moon is increasing, and the Earth's spin is slowing in reaction. Measurements from laser reflectors left during the Apollo missions (lunar ranging experiments) have found that the Moon's distance increases by  per year (roughly the rate at which human fingernails grow).Atomic clocks also show that Earth's day lengthens by about 15 microseconds every year, slowly increasing the rate at which UTC is adjusted by leap seconds.Left to run its course, this tidal drag would continue until the spin of Earth and the orbital period of the Moon matched, creating mutual tidal locking between the two. As a result, the Moon would be suspended in the sky over one meridian, as is already currently the case with Pluto and its moon Charon. However, the Sun will become a red giant engulfing the Earth-Moon system long before this occurrence.

text: The Earth and its Moon are one example of this configuration. Today, the Moon is tidally locked to the Earth; one of its revolutions around the Earth (currently about 29 days) is equal to one of its rotations about its axis, so it always shows one face to the Earth. The Moon will continue to recede from Earth, and Earth's spin will continue to slow gradually. In about 50 billion years, if they survive the Sun's expansion, the Earth and Moon will become tidally locked to each other; each will be caught up in what is called a "spin–orbit resonance" in which the Moon will circle the Earth in about 47 days and both Moon and Earth will rotate around their axes in the same time, each only visible from one hemisphere of the other. Other examples are the Galilean moons of Jupiter (as well as many of Jupiter's smaller moons) and most of the larger moons of Saturn.

text: Cosmic ray exposure history established with noble gas measurements have shown that all lunar meteorites were ejected from the Moon in the past 20 million years.  Most left the Moon in the past 100,000 years.  After leaving the Moon, most lunar meteoroids go into orbit around Earth and eventually succumb to Earth's gravity.  Some meteoroids ejected from the Moon get launched into orbits around the sun.  These meteoroids remain in space longer but eventually intersect the Earth's orbit and land.

text: Limited amateur radio operations have occurred, using moon bounce or Earth–Moon–Earth communication, in which radio signals aimed at the Moon are reflected back to Earth. The first of these operations was on June 13–14, 1964, using the call KP4BPZ. A dozen or so two-way contacts were made on 144 and 432 MHz. On July 3 and July 24, 1965, KP4BPZ was again activated on 432 MHz, making approximately 30 contacts on 432 MHz during the limited time slots available. For these tests, a very wide-band instrumentation recorder captured a large segment of the receiving bandwidth, enabling later verification of other amateur station callsigns. These were not two-way contacts. From April 16–18, 2010, again, the Arecibo Amateur Radio Club KP4AO conducted moon-bounce activity using the antenna.On November 10, 2013, the KP4AO Arecibo Amateur Radio Club conducted a Fifty-Year Commemoration Activation, lasting 7 hours on 14.250 MHz SSB, without using the main dish antenna.

text: Michener dramatizes the life experiences of these men and their families against the backdrop of the real history of the U.S. space program, depicting their experiences in post-war aviation; the space race between the United States and the Soviet Union; the development of congressional funding for the space program; the early failures in the Gemini program; and the successful moon landings in the Apollo program. In a fictional postscript to history, Michener creates a last, "Apollo 18" launch to further the drama of Pope, Claggett and Linley, America's first black astronaut. This is the only Apollo mission in which the lunar module lands on the far side of the Moon; in order to remain in contact with NASA after landing, while still in lunar orbit the Apollo craft must launch communication satellites that will bounce the lunar module's signals to Earth. An exceptional and unexpected burst of sunspot activity results in the death of Claggett and Linley: the two astronauts are exposed to a lethal level of radiation while out on the lunar surface during a large solar flare. After hastily returning to the Lunar Module, Linley loses consciousness and Claggett attempts an emergency ascent back towards the command module. However he also loses consciousness, and the Lunar Module crashes back onto the lunar surface. Pope, the command module pilot, returns to Earth safely. The mission profile is significantly different from that of the real-world canceled mission that would have been Apollo 18.

text: The Earth, Moon, and some other bodies have, to some extent, the property of retroreflection. Light which strikes them is reflected preferentially back in the direction from which it has come, rather than in other directions. If the light comes from the Sun, it is reflected back toward the Sun and in nearby directions. For example, when its phase is full, the Moon reflects light preferentially toward the Sun, and toward the Earth, which is in almost the same direction. The full Moon therefore appears brighter, when seen from Earth, than it would if it diffused light uniformly in all directions. Similarly, near new moon, earthshine which has been retroreflected by the Earth toward the Sun, or toward the Moon which is in almost the same direction, and then retroreflected again by the Moon toward the Earth appears much brighter, seen from Earth, than it would without the retroreflective effects. The retroreflection is produced by spheres of transparent material on the reflecting surface. When it encounters a transparent sphere, light is preferentially reflected and refracted in a path, within the sphere, which exits it in the direction from which it entered. On the Earth, the spheres are droplets of water in clouds. On the Moon, large numbers of solid glassy spheres are found on the surface. They are thought to have been formed from drops of molten rock, produced by impacts, which cooled and solidified before falling back to the surface.

text: The relative age and nature of intercrater plains material are as uncertain in the Borealis region as they are elsewhere on Mercury. Strom noted the similarity in surficial morphologies between mercurian intercrater plains and pre-Imbrian pitted plains south-southwest of Mare Nectaris on the Moon (Wilhelms and McCauley, 1971; Scott, 1972). The pits in the lunar pre-Imbrian pitted plains are similar to the small secondaries that pepper the surface of Mercurian intercrater plains material. On the Moon, pre-Imbrian pitted plains material embays the Janssen Formation (Scott, 1972), whose base is defined as the base of the Nectarian System (Stuart-Alexander and Wilhelms, 1975). However, the crater density of the intercrater plains material in the Borealis region matches that of an area on the far side of the Moon, in the region northwest of crater Tsiolkovskiy bounded by crater Mendeleev and Mare Smithii. This area is dominated by pre-Nectarian unmantled terra and pre-Nectarian and Nectarian craters (Wilhelms and El- Baz, 1977). The similarity in crater density of intercrater plains material on Mercury and of pre-Nectarian terrain on the Moon is geologically significant, inasmuch as it shows that the oldest recognizable surfaces on both Mercury and the Moon went through similar stages of crustal cratering, but not necessarily at the same absolute geologic time. Differences in crater density as well as embayment relations in the Borealis region show that the intercrater plains material and the smoother intermediate plains material are younger than many craters in the area northeast of crater Turgenev, and older than smooth plains material in Borealis Planitia.

text: Lunar Prospector was the third mission selected by NASA for full development and construction as part of the Discovery Program. At a cost of $62.8 million, the 19-month mission was put into a low polar orbit of the Moon, accomplishing mapping of surface composition and possible polar ice deposits, measurements of magnetic and gravity fields, and study of lunar outgassing events. Based on Lunar Prospector Neutron Spectrometer (NS) data, mission scientists have determined that there is indeed water ice in the polar craters of the Moon. The mission ended July 31, 1999 when the orbiter was guided to an impact into a crater near the lunar south pole in an (unsuccessful) attempt to analyze lunar polar water by vaporizing it to allow spectroscopic characterization from Earth telescopes.

text: It is possible to aim a spacecraft from Earth so that it will loop around the Moon and return to Earth without entering lunar orbit, following the so-called free return trajectory. Such circumlunar loop missions are simpler than lunar orbit missions because rockets for lunar orbit braking and Earth return are not required. However, a manned circumlunar loop trip poses significant challenges above and beyond those found in a manned low-Earth-orbit mission, offering valuable lessons in preparation for a manned Moon landing. Foremost among these are mastering the demands of re-entering the Earth's atmosphere upon returning from the Moon.

text: Because the Moon's orbit around Earth is inclined by about 5° to the orbit of Earth around the Sun, eclipses do not occur at every full and new moon. For an eclipse to occur, the Moon must be near the intersection of the two orbital planes. The periodicity and recurrence of eclipses of the Sun by the Moon, and of the Moon by Earth, is described by the saros, which has a period of approximately 18 years.

text: Other mechanisms that have been suggested at various times for the Moon's origin are that the Moon was spun off from the Earth's molten surface by centrifugal force; that it was formed elsewhere and was subsequently captured by the Earth's gravitational field; or that the Earth and the Moon formed at the same time and place from the same accretion disk. None of these hypotheses can account for the high angular momentum of the Earth–Moon system.

text: Lorentz is a huge lunar crater that lies just beyond the northwest limb of the Moon, in a region that is brought into sight of the Earth during favorable librations. This formation is nearly as large as the Mare Nectaris on the near side of the Moon, although it has not been submerged by lava as have the lunar mare. Sections of the crater floor are, however, relatively level, particularly an arc along the western rim. But this last region is still marked by a number of tiny craterlets. The remainder of the interior is rough and irregular, and marked with a multitude of impacts.

text: The cratered terrain, a rolling surface covered by numerous impact craters and centered on Ariel's south pole, is the moon's oldest and most geographically extensive geological unit. It is intersected by a network of scarps, canyons (graben), and narrow ridges mainly occurring in Ariel's mid-southern latitudes. The canyons, known as chasmata, probably represent graben formed by extensional faulting, which resulted from global tensional stresses caused by the freezing of water (or aqueous ammonia) in the moon's interior (see below). They are 15–50 km wide and trend mainly in an east- or northeasterly direction. The floors of many canyons are convex; rising up by 1–2 km. Sometimes the floors are separated from the walls of canyons by grooves (troughs) about 1 km wide. The widest graben have grooves running along the crests of their convex floors, which are called valles. The longest canyon is Kachina Chasma, at over 620 km in length (the feature extends into the hemisphere of Ariel that Voyager 2 did not see illuminated).

text: Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds.

text: The gravitational attraction that masses have for one another decreases inversely with the square of the distance of those masses from each other. As a result, the slightly greater attraction that the Moon has for the side of Earth closest to the Moon, as compared to the part of the Earth opposite the Moon, results in tidal forces. Tidal forces affect both the Earth's crust and oceans.

text: A total solar eclipse will occur on September 3, 2081. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.

text: Baltimore, in the northern portion of the Bay, experiences a noticeable modulation to form its mixed tidal nature during spring vs. neap tides.  Spring tides, when the sun-earth-moon system forms a line, cause the largest tidal amplitudes during lunar monthly tidal variations.  In contrast, neap tides, when the sun-earth-moon system forms a right angle, are muted, and in a semi-diurnal tidal system (such as that seen at the CBBT site) this can be seen as a lowest intertidal range.

text: In 2006, NASA reported that Cassini had found evidence of liquid water reservoirs that erupt in geysers on Saturn's moon Enceladus. Images had shown jets of icy particles being emitted into orbit around Saturn from vents in the moon's south polar region. According to Andrew Ingersoll, California Institute of Technology, "Other moons in the Solar System have liquid-water oceans covered by kilometers of icy crust. What's different here is that pockets of liquid water may be no more than tens of meters below the surface." Over 100 geysers have been identified on Enceladus. In May 2011, NASA scientists at an Enceladus Focus Group Conference reported that Enceladus "is emerging as the most habitable spot beyond Earth in the Solar System for life as we know it".

text: The 20th century brought more advances to study of the Moon. In 1959, Russia's Luna 3 sent back the first photographs of the far side of the Moon, giving the world the first glimpse of the until-then unseen side of our satellite. The United States launched the Ranger spacecraft between 1961 and 1965 to take photographs right down to the instant they impacted the surface, the Lunar Orbiters between 1966 and 1967 to photograph the Moon from orbit, and the Surveyors between 1966 and 1968 to take photos and soft land on the lunar surface. The Russian Lunokhods 1 (1970) and 2 (1973) traversed almost 50 km of the lunar surface, obtaining detailed images of the lunar surface. The Clementine spacecraft obtained the first near global map of the Moon's topography, as well as multispectral images. All of these missions sent back photographs that were of increasingly better resolution.

text: A total solar eclipse occurred on October 2, 1959. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.

text: According to an article in the Guardian, in 2005, deputy minister Qiu Baoxing stated that more than 100 out of the 660 cities had extreme water shortages. Pan Yue, deputy director of the state environment protection agency, warned that economic growth was unsustainable due to the water problems. In 2004 the World Bank warned  that the scarcity of the resource would lead to "a fight between rural interests, urban interests and industrial interests on who gets water in China." In April 2005 there were dozens of injuries in Dongyang city, Zhejiang Province, due to clashes over the nearby chemical factories of the Juxi Industrial Park accused of water pollution that harmed crops and led to deformed babies being born. According to the article, a quarter of the population lacked clean drinking water and less than a third of the waste was treated. China is expected to face worsening water shortages until 2030 when the population peaks.

text: Sinus Iridum (Latin for "Bay of Rainbows") is a plain of basaltic lava that forms a northwestern extension to the Mare Imbrium on Earth's moon. It is surrounded from the northeast to the southwest by the Montes Jura range. The protruding part of the range at the southwest end is named Promontorium Heraclides, while that at the northeast end is called Promontorium Laplace. This bay and the surrounding mountains is considered one of the most beautiful features on the Moon, and is a favorite among lunar observers.

text: ); thus, the orbital parameters of the planets are given in heliocentric terms. The difference between the primocentric and "absolute" orbits may best be illustrated by looking at the Earth–Moon system. The mass ratio in this case is . The Earth–Moon characteristic distance, the semi-major axis of the geocentric lunar orbit, is 384,400 km. The barycentric lunar orbit, on the other hand, has a semi-major axis of 379,700 km, the Earth's counter-orbit taking up the difference, 4,700 km. The Moon's average barycentric orbital speed is 1.010 km/s, whilst the Earth's is 0.012 km/s. The total of these speeds gives a geocentric lunar average orbital speed of 1.022 km/s; the same value may be obtained by considering just the geocentric semi-major axis value.

text: The dark and relatively featureless lunar plains, clearly be seen with the naked eye, are called maria (Latin for "seas"; singular mare), as they were once believed to be filled with water; they are now known to be vast solidified pools of ancient basaltic lava. Although similar to terrestrial basalts, lunar basalts have more iron and no minerals altered by water. The majority of these lavas erupted or flowed into the depressions associated with impact basins. Several geologic provinces containing shield volcanoes and volcanic domes are found within the near side "maria".

text: If the Moon were in a perfectly circular orbit, a little closer to the Earth, and in the same orbital plane, there would be total solar eclipses every month. However, the Moon's orbit is inclined (tilted) at more than 5 degrees to the Earth's orbit around the Sun (see ecliptic), so its shadow at new moon usually misses Earth. Earth's orbit is called the ecliptic plane as the Moon's orbit must cross this plane in order for an eclipse (both solar as well as lunar) to occur. In addition, the Moon's actual orbit is elliptical, often taking it far enough away from Earth that its apparent size is not large enough to block the Sun totally. The orbital planes cross each other at a line of nodes resulting in at least two, and up to five, solar eclipses occurring each year; no more than two of which can be total eclipses. However, total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth's surface traced by the Moon's shadow or umbra.

text: The Aristotelian explanation of gravity is that all bodies move toward their natural place. For the elements earth and water, that place is the center of the (geocentric) universe; the natural place of water is a concentric shell around the earth because earth is heavier; it sinks in water. The natural place of air is likewise a concentric shell surrounding that of water; bubbles rise in water. Finally, the natural place of fire is higher than that of air but below the innermost celestial sphere (carrying the Moon).

text: Sklodowska (Skłodowska) is a large lunar impact crater that is located on the far side of the Moon. It lies just past the southeastern limb, and can sometimes be viewed from Earth under favorable conditions of libration and illumination. The crater is located to the northeast of the older walled plain Curie, and to the southwest of Pasteur, another walled plain.

text: At a laboratory at Camp Evans (part of Fort Monmouth), in Wall Township, New Jersey, a large transmitter, receiver and antenna array were constructed for this purpose. The transmitter, a highly modified SCR-271 radar set from World War II,  provided 3 kilowatts (later upgraded to 50 kilowatts) at 111.5 MHz in -second pulses, applied to the  antenna, a "bedspring" reflective array antenna composed of an 8x8 array of half wave dipoles in front of a reflector which provided 24 dB of gain. Reflected signals were received about 2.5 seconds later, the time required for the radio waves to make the  round-trip journey from the Earth to the Moon and back.  The receiver had to compensate for the Doppler shift in frequency of the reflected signal due to the Moon's orbital motion relative to the Earth's surface, which was different each day, so this motion had to be carefully calculated for each trial.   The antenna could be rotated in azimuth only, so the attempt could be made only as the moon passed through the 15 degree wide beam at moonrise and moonset, as the antenna's elevation angle was horizontal. About 40 minutes of observation was available on each pass as the Moon transited the various lobes of the antenna pattern.

text: During the sequence where Amy attempts to retrieve the keys for the Planet Express Ship from the vending machine, an arcade game titled Gender-Neutral Pac-Person can be seen in the background, a reference to the Namco arcade games Pac-Man and Ms. Pac-Man.Also, The Goophy Gopher Revue is said to have been sponsored by Monsanto, a bioengineering conglomerate from the United States. Crater Face, the Lunar Park mascot, is a reference to the moon from the 1902 French silent film A Trip to the Moon. Bender impales Crater Face in the eye with his beer bottle after Crater Face attempts to confiscate his alcohol, which is another reference to the film as the astronomers' capsule (which resembles a bottle) hitting the moon's eye when it crashes. The title of the episode itself is a reference to the quote "The Eagle has landed" said by astronaut Neil Armstrong when he and Buzz Aldrin touched down on the Moon during the Apollo 11 mission. Fry nearly makes a reference to Neil Armstrong's quote "That's one small step for man, one giant leap for mankind". At the "Destination Moon" lunar rover ride, there is a reference to Ralph and Alice Kramden from the sitcom The Honeymooners. When Fry and Leela are on the surface of the moon and it starts to get dark, it is possible to hear in the background the first chord of the song "Breathe" from Pink Floyd's album The Dark Side of the Moon.

He found that earth tremors occurred most frequently during full and new moons, when the earth is between the sun and moon, when the moon is between the earth and sun, and when the moon is closest in its orbit to the earth.  He also found indications in some cases that the moon had crossed the meridian of affected locales at the time of the earthquake.

text: Astronauts on the Apollo 11, 14, and 15 missions left retroreflectors on the Moon as part of the Lunar Laser Ranging Experiment. The Soviet Lunokhod 1 and Lunokhod 2 rovers also carried smaller arrays. Reflected signals were initially received from Lunokhod 1, but no return signals were detected from 1971 until 2010, at least in part due to some uncertainty in its location on the Moon.  In 2010, it was found in Lunar Reconnaissance Orbiter photographs and the retroreflectors have been used again.  Lunokhod 2's array continues to return signals to Earth. Even under good viewing conditions, only a single reflected photon is received every few seconds. This makes the job of filtering laser-generated photons from naturally occurring photons challenging.

text: Prior to the moon landings O'Keefe developed a theory that tektites, natural glass objects found in discrete strewn fields around the world, are actually volcanic ejecta from the Moon. He suggested that explosive, hydrogen-driven lunar volcanoes may be the mechanism that launched the tektites to Earth. After the moon landings his claim was apparently supported by a chemical analysis of a portion of lunar sample 12013 retrieved by Apollo 12 astronaut Pete Conrad that showed a similar major element composition to some tektites found in Southeast Asia. Some Apollo 14 samples also had chemistries similar to tektites. However, most other lunar data strongly challenged the O'Keefe hypothesis, and almost all researchers in this field now accept that tektites are of terrestrial origin, the products of large meteorite or cometary impacts on Earth. This is supported by geochemical, isotopic and mineralogical evidence, and the fact that most tektite strewn fields can now be confidently matched to known impact craters of similar age on Earth.

text: The concept of a habitable zone has been used by planetary scientists and astrobiologists to define an orbital region around a star in which a planet (or moon) can sustain liquid water. Under this definition, the inner edge of the habitable zone (i.e., the closest point to a star that a planet can be until it can no longer sustain liquid water) is determined by the point in which the runaway greenhouse process occurs. For sun-like stars, this inner edge is estimated to reside at roughly 84% the distance from the Earth to the sun although feedback such as cloud-induced albedo increase could modify this estimate somewhat.

text: The geology of the Moon (sometimes called selenology, although the latter term can refer more generally to "lunar science") is quite different from that of Earth. The Moon lacks a significant atmosphere, which eliminates erosion due to weather; it does not have any form of plate tectonics, it has a lower gravity, and because of its small size, it cooled more rapidly. The complex geomorphology of the lunar surface has been formed by a combination of processes, especially impact cratering and volcanism. The Moon is a differentiated body, with a crust, mantle, and core.

text: Among the remaining irregular moons, Sao and Laomedeia follow prograde orbits, whereas Halimede, Psamathe and Neso follow retrograde orbits. Given the similarity of their orbits, it was suggested that Neso and Psamathe could have a common origin in the break-up of a larger moon. Psamathe and Neso have the largest orbits of any natural satellites discovered in the Solar system to date. They take 25 years to orbit Neptune at an average of 125 times the distance between Earth and the Moon. Neptune has the largest Hill sphere in the Solar System, owing primarily to its large distance from the Sun; this allows it to retain control of such distant moons. Nevertheless, Jupiter's S/2003 J 2 orbits at the greatest percentage of the primary's Hill radius of all the moons in the Solar System on average, and the Jovian moons in the Carme and Pasiphae groups orbit at a greater percentage of their primary's Hill radius than Psamathe and Neso.

text: Two lunar probes were launched in 2009; the Lunar Reconnaissance Orbiter and Lunar Crater Observation and Sensing Satellite were launched on a single Atlas V rocket on 18 June. LRO entered selenocentric orbit and began a series of experiments, whilst LCROSS remained attached to the Centaur upper stage of the carrier rocket, and flew past the Moon. After orbiting the Earth twice, LCROSS separated from the upper stage and both it and the Centaur impacted the Cabeus crater at the South Pole of the Moon, on 9 October. By observing the Centaur's impact, LCROSS was able to confirm the presence of water on the Moon. Several other Lunar probes ceased operations in 2009; Okina impacted the far side of the Moon on 12 February, Chang'e 1 was deorbited on 1 March, having completed its operations. Kaguya was also deorbited following a successful mission, impacting near Gill crater on 12 June. The Chandrayaan-1 spacecraft failed on 29 August, having operated for less than half of its design life.

text: In a review article, Schlesinger et al. list the properties of particulate matter that might elicit adverse effects. The properties that seem pertinent to lunar dust include: size distribution, mass concentration, particle surface area, number concentration, acidity, particle surface chemistry, particle reactivity, metal content, water solubility, and geometric form. In attempting to consider each of these properties, one property emerges as the most difficult to study; particle surface chemistry may be difficult to understand because the environment on the lunar surface is unlike any on Earth, and is likely to alter the surface of dust grains in a way that will render them highly reactive. Recreating the processes that could affect grain surface reactivity on the moon is difficult in an Earth-bound laboratory. Freshly fractured quartz is distinctly more toxic to the rat respiratory system than aged quartz. Quartz and lunar dust may have similar toxic properties, but breaking of surface bonds on mineral substrates has been shown to increase the toxicity of the well-studied mineral quartz.

text: Another thing to consider is that the motion of the Moon is not a perfect circle.  Its orbit is distinctly elliptic, so the lunar distance from Earth varies throughout the lunar cycle. This varying distance changes the apparent diameter of the Moon, and therefore influences the chances, duration, and type (partial, annular, total, mixed) of an eclipse.  This orbital period is called the anomalistic month, and together with the synodic month causes the so-called "full moon cycle" of about 14 lunations in the timings and appearances of full (and new) Moons. The Moon moves faster when it is closer to the Earth (near perigee) and slower when it is near apogee (furthest distance), thus periodically changing the timing of syzygies by up to ±14 hours (relative to their mean timing), and changing the apparent lunar angular diameter by about ±6%.  An eclipse cycle must comprise close to an integer number of anomalistic months in order to perform well in predicting eclipses.

text: The South Pole–Aitken basin is a huge impact crater on the far side of the Moon. Roughly  in diameter and  deep, it is one of the largest known impact craters in the Solar System. It is the largest, oldest and deepest basin recognized on the Moon. It was named for two features on opposing sides; the crater Aitken on the northern end and the southern lunar pole at the other end. The outer rim of this basin can be seen from Earth as a huge chain of mountains located on the lunar southern limb, sometimes called "Leibnitz mountains", although this name has not been considered official by the International Astronomical Union.

text: Cold surface oceans or lakes are found on two worlds, Earth and Saturn's moon Titan. Lava lakes are found on Earth and Jupiter's moon Io. Subsurface oceans or seas occur on the other Galilean moons of Jupiter, Saturn's moons Titan and Enceladus, and are suspected on the some of Saturn's other moons, the asteroid Ceres, the larger trans-Neptunian objects, and ice planets in planetary systems. Recent analysis of the interior of Ganymede, taking into account the effects of salt, suggests that it and some of the other icy bodies may not have a single interior global ocean but several stacked ones, separated by different phases of ice, with the lowest liquid layer adjacent to the rocky mantle below.

text: In most locations, the largest constituent is the "principal lunar semi-diurnal", also known as the M2 (or M) tidal constituent. Its period is about 12 hours and 25.2 minutes, exactly half a tidal lunar day, which is the average time separating one lunar zenith from the next, and thus is the time required for the Earth to rotate once relative to the Moon. Simple tide clocks track this constituent. The lunar day is longer than the Earth day because the Moon orbits in the same direction the Earth spins. This is analogous to the minute hand on a watch crossing the hour hand at 12:00 and then again at about 1:05½ (not at 1:00).

text: In her 40 year long career, Maria Luisa Crawford wrote 68 separate articles in various journals. Her area of research changed several times throughout her career. However, the majority of Crawford's work centered around gaining an understanding of past geological processes related to the earth's crust. There was a period of time when Crawford became very interested in lunar petrology. She was involved in the study of several moon rocks that had been retrieved during the Apollo missions. By studying these rocks she was able to determine that sometime in the moon's history large meteorites struck its surface causing flood lavas. The work she did with lunar rocks is still mentioned in lunar studies to this day.

text: The tidal acceleration of the Moon slows the rotation rate of the Earth and increases the Earth-Moon distance. Friction effects—between the core and mantle and between the atmosphere and surface—can dissipate the Earth's rotational energy. These combined effects are expected to increase the length of the day by more than 1.5 hours over the next 250 million years, and to increase the obliquity by about a half degree. The distance to the Moon will increase by about 1.5 Earth radii during the same period.

text: To return to Earth, the escape velocity of the Moon must be overcome for the spacecraft to escape the gravity well of the Moon. Rockets must be used to leave the Moon and return to space. Upon reaching Earth, atmospheric entry techniques are used to absorb the kinetic energy of a returning spacecraft and reduce its speed for safe landing. These functions greatly complicate a moon landing mission and lead to many additional operational considerations. Any moon departure rocket must first be carried to the Moon's surface by a moon landing rocket, increasing the latter's required size. The Moon departure rocket, larger moon landing rocket and any Earth atmosphere entry equipment such as heat shields and parachutes must in turn be lifted by the original launch vehicle, greatly increasing its size by a significant and almost prohibitive degree.

text: Gliese 876 b, discovered in 1998, and Gliese 876 c, discovered in 2001, are both gas giants discovered in the habitable zone around Gliese 876. Although they are not thought to possess significant water at their surfaces, both may have habitable moons. Upsilon Andromedae d, discovered in 1999, is a gas giant in its star's circumstellar habitable zone considered to be large enough to favor the formation of large, Earth-like moons.

text: When Shea was hired by NASA, President John F. Kennedy's commitment to landing men on the Moon was still only seven months old, and many of the major decisions that shaped the Apollo program were yet to be made. Foremost among these was the mode that NASA would use to land on the Moon. When Shea first began to consider the issue in 1962, most NASA engineers and managersincluding Wernher von Braun, the director of the Marshall Space Flight Centerfavored either an approach called direct ascent, where the Apollo spacecraft would land on the Moon and return to the Earth as one unit, or Earth orbit rendezvous, where the spacecraft would be assembled while still in orbit around the Earth. However, dissenters such as John Houbolt, a Langley engineer, favored an approach that was then considered to be more risky: lunar orbit rendezvous, in which two spacecraft would be used. A command/service module (CSM) would remain in orbit around the Moon, while a lunar module would land on the Moon and return to dock with the CSM in lunar orbit, then be discarded.

text: This shows the spring tide/ neap tide cycle in the amplitudes of the tides as the  moon orbits the earth from being in line (Sun - Earth - Moon, or Sun - Moon - Earth) when the two main influences combine to give the spring tides, to when the two forces are opposing each other as when the angle Moon - Earth - Sun is close to ninety degrees producing the neap tides. Note also as the moon moves around its orbit it also changes from north of the equator to south of the equator. The alternation in the heights of the high tides becomes smaller, until they are the same (the moon is above the equator), then redevelops but with the other polarity, waxing to a maximum difference and then waning again.

text: Because the Moon's mass is a considerable fraction of that of Earth (about 1:81), the two bodies can be regarded as a double planet system, rather than as a planet with a satellite.  The plane of the Moon's orbit around Earth lies close to the plane of Earth's orbit around the Sun (the ecliptic), rather than in the plane perpendicular to the axis of rotation of Earth (the equator) as is usually the case with planetary satellites.  The mass of the Moon is sufficiently large, and it is sufficiently close, to raise tides in the matter of Earth. In particular, the water of the oceans bulges out towards and away from the Moon. The average tidal bulge is synchronized with the Moon's orbit, and Earth rotates under this tidal bulge in just over a day. However, Earth's rotation drags the position of the tidal bulge ahead of the position directly under the Moon. As a consequence, there exists a substantial amount of mass in the bulge that is offset from the line through the centers of Earth and the Moon. Because of this offset, a portion of the gravitational pull between Earth's tidal bulges and the Moon is not perpendicular to the Earth–Moon line, i.e. there exists a torque between Earth and the Moon. This boosts the Moon in its orbit, and slows the rotation of Earth.

text: Eclipses may occur when the Earth and the Moon are equal in value weight and mass with the Sun, and the shadow of one body cast by the Sun falls on the other.  So at new moon, when the Moon is in conjunction with the Sun, the Moon may pass in front of the Sun as seen from a narrow region on the surface of the Earth and cause a solar eclipse.  At full moon, when the Moon is in opposition to the Sun, the Moon may pass through the shadow of the Earth, and a lunar eclipse is visible from the night half of the Earth. Conjunction and opposition of the Moon together have a special name: syzygy (from Greek for "junction"), because of the importance of these lunar phases.

text: Lunar soil is the fine fraction of the regolith found on the surface of the Moon. Its properties can differ significantly from those of terrestrial soil. The physical properties of lunar soil are primarily the result of mechanical disintegration of basaltic and anorthositic rock, caused by continuous meteoric impact and bombardment by interstellar charged atomic particles over years. The process is largely one of mechanical weathering in which the particles are ground to finer and finer size over time. This situation contrasts fundamentally to terrestrial soil formation, mediated by the presence of molecular oxygen (O), humidity, atmospheric wind, and a robust array of contributing biological processes. Some have argued that the term "soil" is not correct in reference to the Moon because on the Earth, soil is defined as having organic content, whereas the Moon has none. However, standard usage among lunar scientists is to ignore that distinction.

text: Recent measurements of the chemical composition of Moon rocks suggest that Earth was born with its water already present. Investigating lunar samples carried to Earth by the Apollo 15 and 17 missions found a deuterium-to-hydrogen ratio that matched the isotopic ratio in carbonaceous chondrites. The ratio is also similar to that found in water on Earth. The findings suggest a common source of water for both objects.  This supports a theory that Jupiter temporarily migrated into the inner Solar System, destabilizing the orbits of water-rich carbonaceous chondrites.  As a result, some of the bodies could have fallen inwards and become part of the raw material for making Earth and its neighbors. The discovery of water vapor out-gassing from Ceres provides related information on water-ice content of the asteroid belt.

text: The original Proto-Indo-European lunar deity appears to have been a male god. In subsequent traditions, the number of male moon deities (or words for "moon" with a male gender) seem to vastly outnumber female ones, which appear to be an exclusively eastern Mediterranean invention. Several goddesses, like Artemis or Hecate, did not originally have lunar aspects, and only acquired them late in antiquity, due to syncretism with Selene/Luna, the de facto Greco-Latin lunar deity. In traditions with male gods, there is little evidence of such syncretism, though the Greco-Roman Hermes has been equated with male Egyptian lunar gods like Thoth. In Greece proper, remnants of male moon gods are also seen with Menelaus.

text: Rotovators can thus be charged by momentum exchange. Momentum charging uses the rotovator to move mass from a place that is "higher" in a gravity field to a place that is "lower". The technique to do this uses the Oberth effect, where releasing the payload when the tether is moving with higher linear speed, lower in a gravitational potential gives more specific energy, and ultimately more speed than the energy lost picking up the payload at a higher gravitational potential, even if the rotation rate is the same. For example, it is possible to use a system of two or three rotovators to implement trade between the Moon and Earth. The rotovators are charged by lunar mass (dirt, if exports are not available) dumped on or near the Earth, and can use the momentum so gained to boost Earth goods to the Moon. The momentum and energy exchange can be balanced with equal flows in either direction, or can increase over time.

text: Tides are controlled mainly by the gravitational pull of the moon. About once a day the moon rotates about the earth, attracting as it travels the bulge of water called the high tide that also travels round the earth. There are actually two high tides, because the earth and moon, as a system, both rotate about a common centre of mass. This centre is two-thirds out from the centre of the earth, not at the centre of the earth. The effect of the earth spinning about this centre is that it behaves as a centrifuge, resulting in a second high tide bulge in the ocean most distant from the moon.

text: Protagonists Mario Esteban Rioz and Ted Long are Scavengers: Mars-born humans who scour space for the spent lower stages of spacecraft, which are then recycled on the Martian moon of Phobos. At the beginning of the story, Rioz scolds Long for wasting power listening to Grounder (Earth-born) politician John Hilder's argument that Earth's settlements on Mars, Venus, and the Moon are useless drains on Earth's economy, and that spaceships are wasting irreplaceable water by using it as reaction mass.

text: Generally, the Moon can be viewed even with the naked eye, however it may be more enjoyable with optical instruments. The primary lunar surface features detectable to the naked eye are the lunar maria or "seas", large basaltic plains which form imaginary figures as the traditional "Moon Rabbit" or familiar "Man in the Moon". The maria cover about 35% of the surface. The contrast between the less reflective dark gray maria and the more reflective gray/white lunar highlands is easily visible without optical aid. Under good viewing conditions, those with keen eyesight may also be able to see some of the following features:

text: In the second episode, Brian considers the nature of motion and explores how the celestial clockwork of the Sun and the Earth-Moon system account for a wide range of natural phenomena observed on Earth, from tropical cyclones and tidal waves to sunrises and seasonal changes. The episode begins in Warton Aerodrome in England with Brian taking to the air in a Eurofighter Typhoon, in an attempt to "beat the Earth's rotation and reverse the passage of the day." In Tacloban, Philippines, Brian narrates how the Coriolis force (caused by the Earth's spin) and the warmth of the tropical waters conspire to give rise to some of the deadliest storms in the world, like Typhoon Haiyan that hit the country in 2013.  Then, in Amapá, Brazil, he relates how the complex gravitational interaction between the Sun and the Moon are not just responsive for the gentle and familiar rise and fall of tides, but also for monstrous tidal bores, like the Pororoca on the waters of the Amazon. Towards the end, he lays out photographs from different points in his life – as a baby, getting married, with his own son, etc. – and concludes by stating that "if Einstein is right, then the past events we remember and our unforeseen future are all out there, somewhere in spacetime."

text: The Moon used to rotate at a faster rate, but early in its history, its rotation slowed and became tidally locked in this orientation as a result of frictional effects associated with tidal deformations caused by Earth. With time, the energy of rotation of the Moon on its axis was dissipated as heat, until there was no rotation of the Moon relative to the Earth. The side of the Moon that faces Earth is called the near side, and the opposite the far side. The far side is often inaccurately called the "dark side", but it is in fact illuminated as often as the near side: once per lunar day, during the new moon phase we observe on Earth when the near side is dark. In 2016, planetary scientists, using data collected on the much earlier Nasa Lunar Prospector mission, found two hydrogen-rich areas on opposite sides of the Moon, probably in the form of water ice. It is speculated that these patches were the poles of the Moon billions of years ago, before it was tidally locked to Earth.

text: Bae proposed a 4-staged developmental map towards interstellar flight. This would involve the Photonic Railway, a permanent energy-efficient transportation infrastructure based on Photonic Laser Thruster (PLT) in combination with Forward's model of beamed-laser propulsion (BLP), a PLT-BLP hybrid. This would reduce the cost and duration of interstellar commutes via proposed spacetrains.  The Stage-1 focuses on the near-earth space endeavors, such as orbit tuning, with Photonic Laser Thruster.  The Stage-2 focuses on Interlunar Photonic Railway between the earth and the moon.  The Stage-3 focuses on Interplanetary Photonic Railway between the earth and planets, moons and asteroids in the solar system.  The Stage-4 focuses on Interstellar Photonic Railway between the planets and moons of the solar system and those of other star systems.

text: A tide clock is a specially designed clock that keeps track of the Moon's apparent motion around the Earth. Along many coastlines the Moon contributes the major part (67 percent) of the combined lunar and solar tides. The exact interval between tides is influenced by the position of the Moon and Sun relative to the Earth as well as the specific location on earth where the tide is being measured. Owing to the Moon's orbital progress, it takes a particular point on the Earth (on average) 24 hours, 50.5 minutes to rotate under the Moon, so the time between high lunar tides fluctuates between 12 and 13 hours. A tide clock is divided into two six-hour-long tidal periods that shows the average length of time between high and low tide in a semi-diurnal tide region such as most areas of the Atlantic Ocean.  Therefore, compared with the actual time between the high lunar tides, tide clocks gain approximately 15 minutes per month and must be reset periodically.

text: Several lines of evidence imply that the lunar core is small, with a radius of about 350 km or less. The size of the lunar core is only about 20% the size of the Moon itself, in contrast to about 50% as is the case for most other terrestrial bodies. The composition of the lunar core is not well constrained, but most believe that it is composed of metallic iron alloyed with a small amount of sulfur and nickel. Analyses of the Moon's time-variable rotation indicate that the core is at least partly molten.

text: This path (or limiting path) may not be unique: there may be many "shortest paths." Also, no path may exist; for example, suppose A lies in a black hole and B lies outside the black hole—since nothing can exit a black hole, such a path would not exist. Finally, because of general relativity, this path is not a "straight line" in the strict Euclidean sense, but is "curved." For example, if we aimed a rocket at the Moon traveling near the speed of light, the shortest path to the Moon is still a curved path. In fact, even if we aimed a photon of light at the Moon, it will follow a curved path, since gravity bends all things. The space along which the photon travels is, in fact, curved because gravity curves space itself.  Just like traveling along the surface of water; if the surface of the water is swelled in a wave, then it would still be possible to travel in a straight line through the water (traveling underneath the wave,) but it would require more effort than just traveling along the curved surface of the water.  It is still possible to travel in a straight line to the Moon, yet since the curved light beam is the best, the curved path close to this beam (following the path of the curved space) is better than the straight path.  This is because the light beam is technically actually traveling in a straight line, relative to the curved space it is traveling in, but the space itself is curved, so it appears to an outside observer that the light beam is traveling in a curved line.  Of course, if we take energy expenditures into account, then the minimum energy paths are just transfer orbits and gravity boosts that Earth space agencies predominantly use although these are not 'fast'.

text: The acceleration due to gravity on the surface of the Moon is 1.62519 m/s, about 16.6% that on Earth's surface or 0.16 . Over the entire surface, the variation in gravitational acceleration is about 0.0253 m/s (1.6% of the acceleration due to gravity). Because weight is directly dependent upon gravitational acceleration, things on the Moon will weigh only 16.6% of what they weigh on the Earth.

text: The lunar horizontal parallax at any time depends on the linear distance of the Moon from the Earth. The Earth–Moon linear distance varies continuously as the Moon follows its perturbed and approximately elliptical orbit around the Earth. The range of the variation in linear distance is from about 56 to 63.7 Earth radii, corresponding to horizontal parallax of about a degree of arc, but ranging from about 61.4' to about 54'. The Astronomical Almanac and similar publications tabulate the lunar horizontal parallax and/or the linear distance of the Moon from the Earth on a periodical e.g. daily basis for the convenience of astronomers (and formerly, of navigators), and the study of the way in which this coordinate varies with time forms part of lunar theory.

text: One such claim is based on an interpretation of the passage in the Quran which states: "Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them and we made every living thing of water? Will they not then believe?" Muslims claim that the first part of the verse is referring to the Big Bang and the second part of the verse refers to the fact that all living things are made of water since and water being a necessary component for life. The notion of "separation of heaven and earth" is common in several other creation stories, some of which preceded the Quran, such as Egyptian mythology, Sumerian mythology, Greek mythology, Hindu mythology, Japanese mythology and Maori mythology. Muslims also believe that the Quran also refers to the protective properties of the atmosphere when it says, "We made the sky a preserved and protected roof yet still they turn away from Our Signs." However, another verse of the Quran says that god withholds the sky from falling on the earth, "Seest thou not that God has made subject to you (men) all that is on the earth, and the ships that sail through the sea by His Command? He withholds the sky from falling on the earth except by His leave: for God is Most Kind and Most Merciful to man." Muslims also believe the Quran mentions the rotation and orbit of the Sun and the Moon when one of its verse states, "It is He who created the night and the day, and the sun, and the moon; each of them swim along in its rounded course." However, others claim that this Quran verse describes the sun and the moon in parallel orbits, as Quran verse 36:40 says, "It is not allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming." However, understanding of the rotation and orbit of the Sun and the Moon, called Geocentrism, existed long before the Quran was written.

text: Riccioli and Grimaldi extensively studied the moon, of which Grimaldi drew maps. This material was included in Book 4 of the New Almagest. Grimaldi's maps were based on earlier work by Johannes Hevelius and Michael Van Langren. On one of these maps, Riccioli provided names for lunar features—names which are the basis for the nomenclature of lunar features still in use today. For example, Mare Tranquillitatis (The Sea of Tranquility, site of the Apollo 11 landing in 1969), received its name from Riccioli. Riccioli named large lunar areas for weather. He named craters for significant astronomers, grouping them by philosophies and time periods. Although Riccioli rejected the Copernican theory, he named a prominent lunar crater "Copernicus", and he named other important craters after other proponents of the Copernican theory such as Kepler, Galileo and Lansbergius. Because craters that he and Grimaldi named after themselves are in the same general vicinity as these, while craters named for some other Jesuit astronomers are in a different part of the Moon, near the very prominent crater named for Tycho Brahe, Riccioli's lunar nomenclature has at times been considered to be a tacit expression of sympathy for a Copernican theory that, as a Jesuit, he could not publicly support. However, Riccioli said he put the Copernicans all in stormy waters (the Oceanus Procellarum). Another noteworthy feature of the map is that Riccioli included on it a direct statement that the moon is not inhabited. This ran counter to speculations about an inhabited moon that had been present in the works of Nicholas of Cusa, Giordano Bruno, and even Kepler, and which would continue on in works of later writers such as Bernard de Fontenelle and William Herschel.

text: One way to determine the lunar parallax from one location is by using a lunar eclipse. A full shadow of the Earth on the Moon has an apparent radius of curvature equal to the difference between the apparent radii of the Earth and the Sun as seen from the Moon. This radius can be seen to be equal to 0.75 degree, from which (with the solar apparent radius 0.25 degree) we get an Earth apparent radius of 1 degree. This yields for the Earth–Moon distance 60.27 Earth radii or  This procedure was first used by Aristarchus of Samos and Hipparchus, and later found its way into the work of Ptolemy. The diagram at right shows how daily lunar parallax arises on the geocentric and geostatic planetary model in which the Earth is at the centre of the planetary system and does not rotate. It also illustrates the important point that parallax need not be caused by any motion of the observer, contrary to some definitions of parallax that say it is, but may arise purely from motion of the observed.

text: Water vapor is a significant component of the Earth's atmosphere and a greenhouse gas. It is also common in the Solar System and by extension, other planetary systems. Its signature has been detected in the atmospheres of the Sun, occurring in sunspots. The presence of water vapor has been detected in the atmospheres of Mercury, Venus, Earth (and Moon), Mars, Jupiter, Saturn, Uranus and Neptune, the planets of the Solar System, although typically in only trace amounts.

text: A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth, and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can occur only the night of a full moon. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes.

text: As seen from the Earth, a solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks ("occults") the Sun. This can happen only at new moon when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured.
