CNN is reporting that NASA has discovered a significant source of water on the moon in the form of a large chunk of lunar ice.

The discovery is based on preliminary data collected when the Lunar Crater Observation and Sensing Satellite, or LCROSS, intentionally crashed October 9 into the permanently shadowed region of Cabeus crater near the moon’s south pole.

NASA: “This isn’t your father’s moon!”

No word yet if Michael Phelps was found practicing his backstroke in said water.
