Two NASA researchers will discuss the agency's latest findings about our home planet and its nearest neighbor in live interviews from the 2009 fall meeting of the American Geophysical Union in San Francisco on Monday, Dec. 14, and Tuesday, Dec. 15.

Monday, Dec. 14, 5:30-7 p.m. EST (2:30 - 4 p.m. PST)

"Back to the Moon, With Water." Michael Wargo, NASA Headquarters
NASA's most recent missions to the moon have uncovered startling new information, including the confirmation of water in a permanently shadowed crater. The Lunar Reconnaissance Orbiter, now circling the moon, also is mapping Earth's dusty satellite in unprecedented detail from many perspectives. NASA's Chief Lunar Scientist Michael Wargo describes what we've discovered this year and previews next directions. To book, contact Grey Hautaluoma at 202-358-0668; grey.hautaluoma-1@nasa.gov

Tuesday, Dec. 15, 5:30-7 p.m. EST (2:30 - 4 p.m. PST)

"Where Has California's Water Gone?" Matthew Rodell, NASA's Goddard Space Flight Center
"Follow the water" has been NASA's mantra in solar system exploration, but what about our home planet? NASA hydrologist Matthew Rodell discusses new findings from the GRACE satellite that show the aquifers in California's Central Valley and the Sierra Nevadas have lost significant water volume since 2003. Rodell can discuss causes and implications of this loss and its impact on California and the U.S. To book, contact Steve Cole at 202-358-0918; stephen.e.cole@nasa.gov

The AGU meeting runs from Monday, Dec. 14, through Friday, Dec. 18, at San Francisco's Moscone Convention Center. NASA scientists and researchers will present a wide range of Earth and space science findings during the meeting.
