Report: NASA’s moon probes will crash into lunar surface

NASA’s GRAIL will end with a fiery crash on the surface of the moon.

Twin space probes, Ebb and Flow, are expected to crash into the moon next Monday, Dec. 17. The probes, which were developed and controlled by NASA, will hurl themselves into the surface of the moon intentionally, marking the end of their journey.

Since 2011, the twin probes have been orbiting the moon in order to create a detailed gravity map of the solar body. Nearly $500 million dollars later, the Grail project, which stands for Gravity Recovery and Interior Laboratory, has finished the map of the moon’s gravity field with an incredible amount of detail.
