Ebb and Flow Crash on the Moon


NASA's twin GRAIL spacecrafts Ebb and Flow ended their mission Monday by crashing into the Moon's surface. The space agency named the site where twin agency spacecraft impacted the moon Monday in honor of the late astronaut Sally K. Ride, who was America's first woman in space and a member of the probes' mission team.     
      
The location of the Sally K. Ride Impact Site is on the southern face of an approximately 1.5-mile-tall (2.5-kilometer) mountain near a crater named Goldschmidt. The impact marked a successful end to the GRAIL mission, which was NASA's first planetary mission to carry cameras fully dedicated to education and public outreach. Ride, who died in July, led GRAIL's MoonKAM (Moon Knowledge Acquired by Middle School Students) Program through her company, Sally Ride Science, in San Diego.
