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
European Lunar Explorer European Lunar Explorer The European Lunar Explorer (ELE) or European Lunar Lander (ELL) was a planned Romanian Lunar lander. It was being developed by ARCA, as an entrant for the Google Lunar X Prize, until it was cancelled in 2014. It was intended to have a mass of 400 kilograms when fully fueled, including two upper stages to propel it from low Earth orbit onto a trajectory towards the Moon. The lander itself had a monopropellant cold rocket engine, fuelled by hydrogen peroxide, which was to slow its descent towards the surface of the Moon. The target landing site was
