In 2011, NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission will launch twin spacecraft in tandem orbits around the Moon to measure its gravity in unprecedented detail. The mission will answer key questions about the Moon’s internal structure and give scientists a better understanding of how our solar system formed.

GRAIL MoonKAM will allow classrooms to request pictures of the lunar surface from cameras on the twin satellites. As we count down to the GRAIL launch, we will be adding exciting features and resources to this site, including student activities, teacher guides, and more.
