Last month, NASA sent its twin GRAIL satellites crashing into the moon—and now, it’s released the final video from that mission, captured by educational cameras on board the probes.

The washing machine-sized GRAIL satellites—nicknamed Ebb and Flow—mapped lunar gravity and revealed that the Moon’s crust is much thinner than originally thought.
