LRO observes mercury and hydrogen explosion in the spectrum probes GRAIL

When NASA's twin probes GRAIL mission scientists were deliberately destroyed, sent spacecraft into collision with the lunar surface in December, complex scientific instruments Orbiter Lunar Reconnaissance Orbiter (LRO) were in a good position to monitor the effects of this collision. In escaped after the explosion of a gas jet tool Lyman Alpha Mapping Project (LAMP), 

located on board the LRO, detected the presence of mercury and hydrogen and was able to measure the change in their numbers over time, as the gas is rapidly expanding into the vacuum of space at speeds approaching speed away from the moon.

NASA made ​​a deliberate collision GRAIL probes to the Moon December 17, 2012, following the successful completion of their basic and advanced science missions related to the preparation of gravity maps of the moon.

The results of the analysis of the LRO spectrographic data show that the moon is the migration of hydrogen to its north pole, which, in turn, may indicate a more widespread distribution of water in lunar craters than previously thought, scientists say.
