Lunar Water Parks?
NASA has found water on the Moon. With concentrations like one liter of water per tonne of lunar regolith, we're talking about wading pools more than water parks (plus it's pretty much frozen). But still - all together there could be billions of liters of water, and it may be much more concentrated in some locations (like shadowed polar craters - LCROSS may give us more data soon). The evidence is spectroscopic, but comes from instruments on three independent spacecraft. Cool!
