Robots will explore lunar craters for ancient water ice, while studies reveal how water arrives on stony planets.
LCROSS sought to observe what the impact might throw up from the lunar shadows. NASA's Lunar Reconnaissance Orbiter watched from afar while a spacecraft behind the rocket sampled the dust plume.
Scientists found 155 kg of water vapour in the dust cloud. First-ever lunar water discovery. LCROSS's lead investigator at NASA's Ames Research Center claimed it was conclusive.
Moon isn't a water source. ASU planetary scientist Mark Robinson called it "strange" Its absence of atmosphere and severe temperatures should evaporate water quickly
Because of the moon's orbit, sunlight can't reach craters like Cabeus. "They're in constant darkness," stated a German planetary scientist.
