CAPE CANAVERAL, Fla. — 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 (6:08 a.m. PDT) Saturday, Sept. 10, 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.

“If there was ever any doubt that Florida’s Space Coast would continue to be open for business, that thought was drowned out by the roar of today’s GRAIL launch,” said NASA Administrator Charles Bolden. “GRAIL and many other exciting upcoming missions make clear that NASA is taking its next big leap into deep space exploration, and the space industry continues to provide the jobs and workers needed to support this critical effort.”

    The GRAIL has been lifted. May it not be lost and do the finding on its Selenological quest! Congrats to all involved with the mission – looking forward to much more news and images back from them. :-)

    Watched it lift off on NASA TV last night. Always great to see.
