NASA missions like Lunar Prospector and the Lunar Crater Observation and Sensing Satellite and instruments like M3 have gathered crucial data that fundamentally changed our understanding of whether water exists on the surface of the moon," said S.
Discovering molecular hydrogen on the moon was a surprise result from NASA's Lunar Crater Observation Sensing Satellite (LCROSS) mission, which crash-landed the LCROSS satellite's spent Centaur rocket at 5,600 miles per hour into the Cabeus crater in the permanently shadowed region of the moon.
Between them they recognised, as others had done before, that there were significant differences between the craters of the Moon and terrestrial calderas, especially in scale; and they set out to explain those differences and advance a coherent theory of lunar crater formation by volcanic means.
Pictures of the crash were supposed to be beamed by the second probe Lcross - short for Lunar Crater Observation and Sensing Satellite.
