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
Explorer 45 The spin rate was about 7 rpm, and the spin axis lay in the spacecraft orbital plane which was approximately the same as the earth's equatorial plane. The initial local time of apogee was about 21.8 hours and the line of apsides moved around toward the sun at an initial rate of 12° per month. The satellite was operationally turned off on 30 September 1974, after approximately 3 years of successful and productive operation. Explorer 45 Explorer 45 (also called as S-Cubed A and SSS-A) was a NASA satellite launched as part of Explorers program. Explorer 45 as launched on
