Nearly a year after announcing the discovery of water molecules on the moon, scientists Thursday revealed new data uncovered by NASA's Lunar CRater Observation and Sensing Satellite, or LCROSS, and Lunar Reconnaissance Orbiter, or LRO. The missions found evidence that the lunar soil within shadowy craters is rich in useful materials, and the moon is chemically active and has a water cycle. Scientists also confirmed the water was in the form of mostly pure ice crystals in some places. The...

The complete archive of data sets from ESA's 3-year SMART-1 mission to the Moon has been released to the scientific community. Contained within the archive are 3D maps of the lunar poles along with detailed spectroscopic measurements of the lunar surface. Researchers can utilize this information, and cross-reference it with the wider Planetary Science Archive, to further investigate the formation and evolution of our nearest neighbor in space. Launched in September 2003, SMART-1 became the...

The recent discovery of water on the Moon may have a serious impact on future plans for lunar based astronomy.  Space scientists from the Chinese Academy of Sciences have calculated that the scattering caused by molecules vaporized in sunlight could heavily distort observations from telescopes mounted on the Moon. "Last year, scientists discovered a fine dew of water covering the Moon. This water vaporizes in sunlight and is then broken down by ultraviolet radiation, forming hydrogen and...

GREENBELT, Md., Sept. 16 /PRNewswire-USNewswire/ -- The moon was bombarded by two distinct populations of asteroids or comets in its youth, and its surface is more complex than previously thought, according to new results from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft featured in three papers appearing in the Sept. 17 issue of Science.

The moon was bombarded by two distinct populations of asteroids or comets in its youth, and its surface is more complex than previously thought, according to new results from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft featured in three papers appearing in the Sept. 17 issue of Science. In the first paper, lead author James Head of Brown University in Providence, R.I., describes results obtained from a detailed global topographic map of the moon created using LRO's Lunar Orbiter...

Earth's next-door neighbor, the Moon, has been found by astronomers to be shrinking, but only by a miniscule amount.Astronomers reported Thursday in the US journal Science that they had discovered previous undetected cracks in the moon's crust that formed as the interior cooled and shrunk over the last billion or so years. The finding indicates that the lunar satellite has definitely gotten smaller, though not enough that it would be noticed by just gazing at it.Scientists have identified 14...

While scientists have long searched for water on the Moon, a new study asserts that the Earth's satellite is actually quite dry--too dry, in fact, to sustain life.The paper, entitled "The Chlorine Isotope Composition of the Moon and Implications for an Anhydrous Mantle," was published Thursday in Science Express. It is the work of scientists from the University of New Mexico (UNM), the University of Texas at Austin, the University of California-Los Angeles, and Los Alamos National...

Researchers sifting through Google Earth images have discovered what may be the world's best-preserved small impact crater in a remote area of the Sahara desert in southwestern Egypt.   The immaculate, 148 ft. wide crater was likely excavated by a fast-moving iron meteorite, a few thousand years ago, scientists said Thursday. Dubbed Kamil, the crater is remarkably preserved when compared with most of the other craters on the Earth's surface, many of which are partially eroded. The...

That dry, dusty moon overhead? Seems it isn't quite as dry as it's long been thought to be. Although you won't find oceans, lakes, or even a shallow puddle on its surface, a team of geologists at the California Institute of Technology (Caltech), working with colleagues at the University of Tennessee, has found structurally bound hydroxyl groups (i.e., water) in a mineral in a lunar rock returned to Earth by the Apollo program. Their findings are detailed in this week's issue of the journal...

The Moon's geological past could be better understood by a mineral that Japanese astronomers report they have found. Using an instrument-loaded probe - Kaguya - placed in orbit around the lunar body in 2007, the team of scientists found abundant sources of the mineral in concentric rings in three distinct crater regions. Olivine, as the mineral is known, is believed to be a revealing sign of mantle -- the deep inner layer of iron- and magnesium-rich rock that lies beneath the Moon's crust....

The Hadean is the unofficial geological period of time that lies just before the Archean time period. The Hadean began with the formation of the Earth roughly 4.5 billion years ago (Ga) and ended about 3.8 Ga; the latter date varies according to different sources. Hadean is derived from Hades, Greek for “underworld,” referring to the hellish conditions on the planet at the time. The term was coined in 1972 by geologist Preston Cloud. The period was later classified as the “Priscoan...

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...

The Moon -- The Moon is the largest satellite of the Earth, and is occasionally called Luna (Latin for moon) to distinguish it from the general use of the word "moon". The Moon is distinguished from the satellites of other planets by its initial capital letter; the other moons are described in the natural satellite article. The words moon and month come from the same Old English root word. The Moon makes a complete orbit of the celestial sphere about every four weeks. Each hour the...

The Moon -- natural satellite of a planet, in particular, the single natural satellite of the earth. The Earth-Moon System The moon is the earth's nearest neighbor in space. In addition to its proximity, the moon is also exceptional in that it is quite massive compared to the earth itself, the ratio of their masses being far larger than the similar ratios of other natural satellites to the planets they orbit (with the exception of Charon and Pluto). For this reason, the...
