Ebb and Flow, the two space probes that were sent out as a part of NASA's GRAIL mission, went out with a bang one month ago. Their mission was to map out the Moon's gravitational field so that scientists could better understand it's interior. When their mission was complete it was decided that the probes should crash into the moon to free up space in orbit. During their last moments, the two probes filmed their descent.
Here is the stunning video.
