NASA's twin lunar Gravity Recovery and Interior Laboratory (GRAIL) probes were launched from Cape Canaveral Air Force Station on Sept. 10, 2011. GRAIL-A is scheduled to arrive in lunar orbit beginning at 1:21 p.m. PST on Saturday, Dec. 31, and GRAIL-B on Sunday, Jan. 1, beginning at 2:05 p.m. PST. After confirmation they are in orbit and operating nominally, the two solar-powered spacecraft will fly in tandem orbits to answer longstanding questions about the moon and give scientists a better understanding of how Earth and other rocky planets in the solar system formed. Participants are: - Maria Zuber, principal investigator, Massachusetts Institute of Technology, Cambridge - David Lehman, project manager, NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. To participate, reporters must contact the JPL Media Relations Office at 818-354-5011 by 10:30 a.m. PST on Dec. 28 for the call-in number and passcode.
