Latest Gravity Recovery and Interior Laboratory Stories

redOrbit Staff & Wire Reports - Your Universe Online Using instruments on board the Lunar Reconnaissance Orbiter (LRO), NASA officials were able to detect mercury and hydrogen in the gas plumes that arose following the impact of the twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft last December, the US space agency announced on Tuesday. The LRO’s Lyman Alpha Mapping Project (LAMP) also measured the time evolution of those gases as they rapidly expanded into the...

WATCH VIDEO: [LAMP Observes GRAIL Impact] Lawrence LeBlond for redOrbit.com - Your Universe Online After spending nearly a year in lunar orbit studying the moon’s interior, two NASA spacecraft, known as GRAIL A (Ebb) and GRAIL B (Flow), were ordered to embark on a final mission that would hopefully give scientists one last bit of data about the moon’s composition. The twin spacecraft, which were launched in September 2011 and arrived in lunar orbit in late December 2011 and early...

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...

DENVER, Dec. 17, 2012 /PRNewswire/ -- NASA's Gravity Recovery And Interior Laboratory (GRAIL) mission came to an end today as planned when the Lockheed Martin (NYSE: LMT) and the Jet Propulsion Laboratory (JPL) flight operations team commanded the two spacecraft to de-orbit and impact the surface of the moon. Lockheed Martin built the twin robotic spacecraft and conducted flight operations for NASA's JPL since their launch on Sept. 10, 2011. The first of the orbiters, Ebb,...

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, closing...
