NASA's LCROSS (Lunar CRater Observing and Sensing Satellite) mission is coming to a glorious end. The mission launched on June 18, 2009 is just minutes away from making dual-impact on the face of the moon. The first impact sees the Centaur craft hitting the surface at a speed of about 1 mile per second. That should eject about 350 tons of debris from a crater about 20-30-meters in diameter and 2- to 4-meters deep. A second Shepherding spacecraft will pass through the debris plume 4 minutes later, collecting and relying data back to Earth in real-time before meeting its end. With any luck, we'll know shortly if the moon contains the water-ice theorized by scientists and cheese. While the obvious use of lunar-based water is to sate the thirst of astronauts, it could also be used be make
