According to a new NASA Headline article, the search for water on the moon will be taken up by a robot space probe called the Lunar Reconnaissance Orbiter. The LRO will use a variety of detection methods including the Lyman-Alpha Mapping Project's UV spectrometer to look for ice within permanently shadowed craters near the poles. The water will be needed when manned missions return to the moon, hopefully by 2020. For more on the LRO, see the NASA LRO Home Page and the NASA Robotic Lunar Exploration site.
