"It ain't so much what we know that gets us into trouble. It's what we know that just ain't so" - Mark Twain
The moon is - wet?
While the hoped for Earth-visible plume never really materialized, the science kicked up by the 2009 lunar impactor LCROSS has certainly gotten a lot of attention. This week, analysis of the material ejected from the Cabeus crater has been published showing the presence of billions of gallons of water ice in that one region alone.
In fact, scientists now believe that the regolith, or soil, may conceal a "lunar permafrost," enough water - and in an easily retrievable form - to support human settlement.
