NASA's GRAIL Lunar Impact Site Named After Sally Ride
2012-12-18 12:02:58

NASA Science NASA has named the site where twin gravity probes hit the Moon yesterday in honor of the late astronaut, Sally K. Ride, who was America's first woman in space and a member of the probes' mission team. On Dec. 14th, Ebb and Flow, the two spacecraft of NASA's GRAIL (Gravity Recovery and Interior Laboratory) mission, were commanded to descend into a lower orbit and target a mountain near the Moon's north pole. The formation-flying duo hit the lunar surface as planned at...

Lee Rannals for redOrbit.com — Your Universe Online The GRAIL lunar mission came to a crashing halt today after the twin probes (Ebb and Flow) smashed into the Moon in a blaze of glory. The twin probes have had a successful run, and the mission ending burn-out into the lunar surface was planned out by NASA from the beginning. NASA said its GRAIL probes found their way towards the lunar surface at about 2:28 p.m. pacific time on Monday. The mission ended successfully,...

[ Watch the Video: Last Flight For GRAIL's Twin Spacecraft] Lee Rannals for redOrbit.com - Your Universe Online After a year run, NASA is preparing to end the twin lunar-orbiting GRAIL probes' mission with a bang — into the Moon, that is. NASA said that the twin spacecraft are being prepared for their controlled descent and impact on a mountain near the moon's north pole next Monday at 2:28 p.m. Pacific time. The Gravity Recovery and Interior Laboratory (GRAIL) mission...

Moon's Interior Was Pulverized By Early Impacts
2012-12-05 13:28:06

[ Watch the Video: GRAIL's Gravity Tour of the Moon ] Lee Rannals for redOrbit.com - Your Universe Online Scientists using data from NASA's GRAIL mission have determined that the Moon's interior is nearly completely pulverized. The latest finding from the Gravity Recovery and Interior Laboratory (GRAIL) mission suggests that during the Moon's first billion years, it may have endured more fracturing from massive impacts than previously thought. Planetary scientists have stitched...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
