(KTVI)) – A pair of robotic probes that have been mapping the moon crashed into the lunar surface Monday afternoon. The Gravity Recovery and Interior Laboratory (GRAIL) probes, Ebb and Flow, crashed into a mountain near the lunar north pole around 4:28pm St. Louis time.

NASA is crashing the probes because they’re running out of fuel.

NASA scientists now have the highest-resolution gravity field map of any celestial body thanks to the probes. They also have insight into what’s below the moon’s surface and how the moon may have formed.
