    NASA's radar experiment aboard India's Chandrayaan-1 spacecraft orbiting the Moon has identified thick deposits of water-ice in more than 40 small craters near the Moon's north pole. Ranging from one to 9 miles across, the craters likely contain ice at least a few meters thick, leading to total estimates of at least 600 million metric tons of ice within these craters.
