To learn more about the composition of the moon, NASA crashed its two lunar probes into a mountain near the moon's North Pole on last Friday.
ACCORDING TO NASA, the two Gravity Recovery and Interior Laboratory (GRAIL) probes called 'Ebb' and 'Flow' will be deliberately crashed as a part of an experiment after they have run out of fuel to keep them in lunar orbit.
Though, later, the event will be broadcast on NASA TV to show how the operation was carried out, but images of the actual crash won't be available because the region on the moon where the impact is expected to take place was in shadows at the time of the crash.
The GRAIL mission was launched in September 2011 for mapping lunar gravity between March and May this year. The crash data will reveal more information on the composition of the noon.
Rocket burns nudged GRAIL probes Ebb and Flow into a orbit designed to crash them into the side of a mountain at around 2:28 p.m. Pacific standard time on last Friday. NASA has named the crash site after late astronaut Sally Ride, America's first woman in space.
