Three separate missions examining the moon have found clear evidence of water there. Apparently, concentrated at the poles and possible formed by the solar wind.  US Geological Survey scientist, Roger Clark.

“Now what’s astounding about this result is that the water and hydroxyl exist at all latitudes on the moon in direct sun light where it's really quite hot, in fact, hotter at the equator than boiling water.”

The findings to published in the journal Science on Friday show the water may be actively moving around, forming and reforming as particle mixed up in the dust on the surface of the moon.  Next month, NASA’s Lunar CRater observation and Sensing Satellite mission will try to detect water by deliberately crashing a large spacecraft onto the moon.
