Space: Doomed GRAIL Moon Mission

Here from Scientific American is dramatic footage of the doomed Ebb satellite as it circled the moon at an altitude of 6 miles. On December 17th 2012 two small spacecraft called Ebb and Flow hit the lunar surface at over 3,700 miles an hour. This ended the year long mission of NASA’s Gravity Recovery and Interior Laboratory (GRAIL).
