 While scientific experiments performed by Clementine and Lunar Prospector could indicate the presence of water in the polar craters , the current evidence is far from definitive . There are doubts among scientists as to whether or not the hydrogen is in the form of ice , as well as to the concentration of this " ore " with depth below the surface . Resolution of this issue will require future missions to the Moon . The presence of water suggests that the crater floor could potentially be " mined " for deposits of hydrogen in water form , a commodity that is expensive to deliver directly from the Earth .
