Disney Name Goes Interplanetary With Impact Crater Identity
2012-12-21 13:55:02

Lee Rannals for redOrbit.com - Your Universe Online Mercury has gained a little more fame in the eyes of Hollywood, after the International Astronomical Union (IAU) agreed to name nine impact craters after Walt Disney. The MESSENGER Science Team proposed nine names for impact craters on Mercury, all of which refer to either a blues singer, animation pioneer Walter Elias "Walt" Disney, or other artists. IAU has been the gatekeeper for planetary and satellite nomenclature since 1919,...

Minnesota’s Apollo 11 Moon Rocks Found In National Guard Storage Unit
2012-11-27 08:17:26

Lawrence LeBlond for redOrbit.com - Your Universe Online Hundreds of moon rocks that have been handed out to state governments and foreign countries through the years have gone missing, according to a NASA audit last December. Though some have been recovered, most are still missing. On a good note, another set of lunar pebbles were found this week in a government storage area in St. Paul, Minnesota. The rocks were part of the Apollo 11 lunar landing mission on July 20, 1969 in which...

Mercury Has Unusual Tectonic Landforms
2012-11-16 09:30:37

[ Watch the Video: What Is Mercury ] April Flowers for redOrbit.com - Your Universe Online MESSENGER, in orbit around Mercury since March of last year, has discovered assemblages of tectonic landforms unlike any previously found on Mercury or elsewhere in the Solar System. Smithsonian scientist Thomas Watters published the findings in the December issue of Geology. Mercury's surface is covered with deformational landforms, formed by faulting in response to horizontal contraction or...

Moon: Light Side or Dark?
2012-10-30 19:44:18

Lee Rannals for redOrbit.com — Your Universe Online Researchers are saying the massive dark spot seen on the moon, known as the Ocean of Storms, is a scar from a giant cosmic impact. The team of Japanese scientists says the giant cosmic impact created a magma sea more than a thousand miles wide and several hundred miles deep. The findings may be able to help explain why the moon's near and far sides are so different from one another. The side of the moon that faces Earth has...

Lunar Lander Will Search For Moon Ice And Water
2012-10-22 06:00:34

redOrbit Staff & Wire Reports - Your Universe Online European researchers are in the process of building an unmanned probe that would travel to the moon, where it would search for subsurface ice on the lunar surface, within the next six years. The $800 million (£500 million) project, which is detailed in an October 21 article by Telegraph Science Correspondent Richard Gray, is currently being planned by the European Space Agency (ESA) and is on pace to take place sometime in...

Moon Formation - Evidence Backs Up Giant Impact Theory
2012-10-17 14:15:54

[ Watch the Video: What is the Moon? ] | [ Watch the Video: Planetary Demolition Derby ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are backing up a theory, claiming that the Moon was created when a planetary body the size of Mars collided with Earth. Planetary scientists found evidence that backs up the Giant Impact Theory, which was first proposed at a conference in 1975. The Giant Impact Theory says that Earth´s moon was created in an apocalyptic...

Lunar Water Found In Apollo Soil Samples
2012-10-15 04:11:33

redOrbit Staff & Wire Reports - Your Universe Online Water molecules discovered in soil samples collected from the moon could have indirectly originated from the sun, claim the authors of a new study published Sunday in the journal Nature Geoscience. The researchers studied soil samples brought back from the lunar surface during the Apollo missions, and discovered that they contained compounds known as hydroxyls, which are essentially substructures of an H2O molecule, according to...

Water May Have Been Deposited On Vesta Asteroid Long Ago
2012-09-26 14:42:05

Lee Rannals for redOrbit.com — Your Universe Online Astronomers suggest that water may have been delivered to Vesta through a build-up of small particles during an epoch when the Solar System was rich in dust. The team presented their research at the European Planetary Science Congress in Madrid on Wednesday, offering up a radically different hypothesis from the way in which hydrous materials are deposited on other cosmic objects. Using data from NASA's Dawn mission, the team...

Theia Collision With Earth To Form The Moon
2012-08-30 10:16:41

April Flowers for redOrbit.com - Your Universe Online Around 4.5 billion years ago, the Earth is believed to have collided with an impactor the size of Mars known as "Theia." This collision, current theory says, is what formed the Moon. Scientists have simulated this formation process and reproduced many of the Earth-Moon system properties. However, these simulations have also given rise to a problem known as the Lunar Paradox. According to the Paradox, the Moon seems to be made up of...

LRO Finds Traces Of Helium Around The Moon
2012-08-16 05:19:20

April Flowers for redOrbit.com - Your Universe Online Using the Lyman Alpha Mapping Project (LAMP) spectrometer aboard NASA's Lunar Reconnaissance Orbiter (LRO), scientists have made the first spectroscopic observations of the noble gas helium in the atmosphere surrounding the Moon. These remote-sensing observations complement the situ measurements taken in 1972 by the Lunar Atmosphere Composition Experiment (LACE) deployed by Apollo 17. LAMP was originally designed to map the lunar...

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...
