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
Aeronomy of Ice in the Mesosphere a month however. Aeronomy of Ice in the Mesosphere The Aeronomy of Ice in the Mesosphere (AIM) is a satellite to conduct a 26-month study of noctilucent clouds (NLCs). It is the ninetieth Explorer program mission and is part of the NASA-funded Small Explorer program (SMEX). On April 25, 2007 AIM was boosted into a high polar orbit by a Pegasus-XL rocket, which was air-launched from the Lockheed L-1011 "Stargazer" aircraft operated by Orbital Sciences. The AIM satellite is a , by spacecraft, powered by two solar arrays, carrying three instruments: The noctilucent clouds AIM is to study, also known
