NASA's Gravity Recovery And Interior Laboratory (GRAIL), mission to study the Moon is in final launch preparations for a scheduled September 8 launch onboard a Delta II rocket from Cape Canaveral Air Force Station in Florida.
GRAIL's twin spacecraft are tasked for a nine-month mission to explore Earth's nearest neighbor in unprecedented detail. They will determine the structure of the lunar interior from crust to core and advance our understanding of the thermal evolution of the moon. (go to NASA/GRAIL)
