The launch is targeted for 8:37 a.m. EDT on Sept. 8. The two GRAIL spacecraft will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail from crust to core. The mission also will answer longstanding questions about the moon and provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed.
