NASA Crash lands on the moon for scientific reasons Answered
NASA crash landed a space craft named "SMART-1" into a crater in the southern parts of the moon where the sun never shines to "kick up the dust" and analyze it with a following craft called "Centaur" for water and mineral compounds. I watched it live here www.nasa.gov/55644main_NASATV_Windows.asx which I have got to say was pretty cool, but you can watch the last bits of it here www.youtube.com/watch. Watch the guy try hi-five his mate.
Whole story here www.nasa.gov/vision/universe/watchtheskies/30aug_smart1.html, it's pretty amazing.
