First Interactive Mosaic Of Lunar North Pole Released By NASA
2014-03-18 20:40:18

NASA Scientists, using cameras aboard NASA's Lunar Reconnaissance Orbiter (LRO), have created the largest high resolution mosaic of our moon’s north polar region. The six-and-a-half feet (two-meters)-per-pixel images cover an area equal to more than one-quarter of the United States. Web viewers can zoom in and out, and pan around an area. Constructed from 10,581 pictures, the mosaic provides enough detail to see textures and subtle shading of the lunar terrain. Consistent lighting...

Moon Gets New Face GRAIL
2013-11-11 08:26:13

[ Watch the Video: Man In The Moon Got His Looks From Asteroids ] redOrbit Staff & Wire Reports - Your Universe Online Scientists have long believed that the moon’s trademark craters were created from the impact of massive asteroids, but new research appearing in the journal Science suggests that smaller planetoids might actually have been responsible for pummeling the lunar surface. The lunar craters were believed to have been created approximately four billion years ago,...

Moon Mystery: GRAIL Data Show How Gravitational Anomalies Developed
2013-05-31 06:19:45

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Purdue University and MIT have solved the long-standing mystery of why the moon´s gravitational force is stronger in some areas than in others. This irregular gravitational force has been observed ever since the first satellites were sent to the moon, when orbiting probes would pass over certain craters and impact basins, and periodically swerve off course before plunging toward the lunar surface and then...

PASADENA, Calif., May 30, 2013 /PRNewswire-USNewswire/ -- NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission has uncovered the origin of massive invisible regions that make the moon's gravity uneven, a phenomenon that affects the operations of lunar-orbiting spacecraft. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Because of GRAIL's findings, spacecraft on missions to other celestial bodies can navigate with greater precision in the future. GRAIL's twin...

Lunar Reconnaissance Orbiter Detects Hydrogen, Mercury From Twin GRAIL Impacts
2013-03-27 12:00:36

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...

NASA Lunar Orbiter Captures Stunning Images Of Twin GRAIL Impacts

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...

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...

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, impacted...
