This is the final video sequence captured by the GRAIL-A ("Ebb") MoonKAM system a few days before the spacecraft impacted the Moon on a mountain near the lunar north pole on Dec 17. At the time this video was taken, both GRAIL spacecraft were about 6 miles (10 km) above the northern hemisphere of the Moon's far side, in the vicinity of the Jackson impact crater. This imagery was acquired as part of a final checkout of spacecraft equipment prior to its planned impact.
