Grail Impacts Moon as Planned, Site Named for Sally Ride
(Source NASA) – NASA has 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. Last Friday, Ebb and Flow, the two spacecraft comprising NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, were commanded to descend into a lower orbit that would result in an impact Monday on a mountain near the moon’s north pole. The formation-flying duo hit the lunar surface as planned at 2:28:51 p.m. PST (5:28:51 p.m. EST) and 2:29:21 p.m. PST (5:29:21 p.m. EST) at a speed of 3,760 mph (1.7 kilometers per second). The location of the Sally K. Ride Impact Site is on the southern face of an approximately 1.5 mile- (2.5 -kilometer) tall mountain near a crater named Goldschmidt. “Sally was all about getting the job done, whether it be in exploring space, inspiring the next generation, or helping make the GRAIL mission the resounding success it is today,” said GRAIL principal investigator [...]
