Prospecting for Lunar Water

In the 1990s, the Lunar Prospector and Clementine found signs of ice in the shadowed craters never the Moon's poles. There has been no substantial evidence for ice however. NASA's future plans for lunar colonization hinges on finding water on the Moon. Water would be useful for lunar colonists as drinking water, water to grow food, provide oxygen and rocket fuel, as well, water is very effective in blocking space radiation. In 2008, NASA will launch the Lunar Reconnaissance Orbiter to map the lunar environment. It's hoped that the LRO will confirm water on the Moon, and will set the stage for the return to the Moon in 2020.
