CAPE CANAVERAL, Fla. -- NASA's GRAIL spacecraft is set to launch to the moon aboard a
United Launch Alliance Delta II rocket on Sept. 8, 2011, from Cape Canaveral Air Force Station,
Fla. There are two instantaneous (one-second) launch windows at 8:37:06 a.m. and 9:16:12 a.m.
EDT (5:37:06 a.m. and 6:16:12 a.m. EDT). The launch period extends through Oct. 19. The launch
times occur approximately 4 minutes earlier each day.

GRAIL's primary science objectives are to determine the structure of the lunar interior, from crust
to core, and to advance understanding of the thermal evolution of the moon.
