Will Study Moon From Crust To Core
NASA's twin lunar Gravity Recovery and Interior Laboratory
(GRAIL) spacecraft lifted off from Cape Canaveral Air Force Station
in Florida at 9:08 a.m. EDT Saturday to study the moon in
unprecedented detail. GRAIL-A is scheduled to reach the moon on New
Year's Eve 2011, while GRAIL-B will arrive New Year's Day 2012. The
two solar-powered spacecraft will fly in tandem orbits around the
moon to measure its gravity field. GRAIL will answer longstanding
questions about the moon and give scientists a better understanding
of how Earth and other rocky planets in the solar system
formed.
