WASHINGTON, March 7, 2012 /PRNewswire-USNewswire/ -- NASA's Gravity Recovery And Interior Laboratory (GRAIL) spacecraft orbiting the moon officially have begun their science collection phase. During the next 84 days, scientists will obtain a high-resolution map of the lunar gravitational field to learn about the moon's internal structure and composition in unprecedented detail. The data also will provide a better understanding of how Earth and other rocky planets in the solar system...

[ Watch the Video ] NASA's Gravity Recovery And Interior Laboratory (GRAIL) mission has returned its first unique view of the far side of the moon. The space agency said that in the video, the north pole of the moon is visible at the top of the screen as the spacecraft flies toward the lunar south pole. One prominent geological feature seen on the lower third of the moon is the mare Orientale, which is a 560-mile wide crater that lies on both the moon's near and far side. Towards...

NASA's Gravity Recovery And Interior Laboratory (GRAIL)-B spacecraft successfully executed its first flight path correction maneuver Wednesday, Oct. 5. The rocket burn helped refine the spacecraft's trajectory as it travels from Earth to the moon and provides separation between itself and its mirror twin, GRAIL-A. The first burn for GRAIL-A occurred on Sept. 30. "Both spacecraft are alive and with these burns, prove that they're kicking too, as expected," said David Lehman, GRAIL project...
