NASA Announces Launch Tweetup for GRAIL Moon Mission


NASA will host a two-day launch Tweetup for 150 of its Twitter followers on Sept. 7-8 at the agency's Kennedy Space Center in Florida. The Tweetup is expected to culminate in the launch of the twin lunar-bound GRAIL spacecraft aboard a Delta II rocket from Cape Canaveral Air Force Station in Florida.

The launch window opens at 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, from its crust to core, in unprecedented detail. The mission also will answer longstanding questions about Earth’s moon and provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed.
