Lunar water true, this would indicate that the neutron results from Lunar Prospector were primarily from hydrogen in forms other than ice, such as trapped hydrogen molecules or organics. Nevertheless, the interpretation of the Arecibo data do not exclude the possibility of water ice in permanently shadowed craters. In June 2009, NASA's "Deep Impact" spacecraft, now redesignated EPOXI, made further confirmatory bound hydrogen measurements during another lunar flyby. As part of its lunar mapping programme, Japan's Kaguya probe, launched in September 2007 for a 19-month mission, carried out gamma ray spectrometry observations from orbit that can measure the abundances of various elements
Fast Auroral Snapshot Explorer Fast Auroral Snapshot Explorer The Fast Auroral Snapshot Explorer (FAST) is a NASA plasma physics satellite, and is the second spacecraft in the Small Explorer program. It was launched on August 21, 1996, from Vandenberg Air Force Base aboard a Pegasus XL rocket. The spacecraft was designed and built by NASA's Goddard Space Flight Center. Flight operations were handled by Goddard for the first three years, and thereafter were transferred to the University of California, Berkeley's Space Sciences Laboratory. FAST was designed to observe and measure the plasma physics of the auroral phenomena which occur around both of Earth's poles.
