The surface of the moon occupies a meteor explosion of eons scars, but these cosmic strikes are also the key to an incredible new discovery of our satellite: it removes water drops in meteor shower.
NASA scientists have found that meteorite blasts over the moon's surface are powerful enough to force small drops of water from the dust of the lunar soil and into the atmosphere above.
"The water-letting moon surface is protected by a layer – a few centimeters – of dry soil that can only be damaged by large micrometeoroids," says Mehdi Benna, a planetary scientist at the Baltimore County of the University of Maryland, University of Maryland

When these small meteoroids hit the Moon, they can force water drops that cover the moon's grain below the drier surface layer. Most of the materials in the impact crater are simply evaporated and enter the space, but about one-third of the water forced to leave the meteorite hits the moon's surface.
Emissions can be detected by sensitive NASA instruments on the Lunar spacecraft (LADEE) spacecraft. Analyzing these data, the team noticed a clear pattern of these water emissions and meteorite showers
The study means that the amount of water is scattered across the lunar surface. which can be very interesting and valuable for future space exploration missions.
As for where the water comes from, the team says it has removed the possibility of coming from the meteorites itself: "We know that some of the water should be from the moon, because the water mass discharged is higher than the mass of the incoming meteoroids "Said the second author, Dana Hurley, of John Hopkins University's Applied Physics Laboratory
Benna, a leading water study author, adds: " The water that is lost is likely to be ancient, or since the Moon. or in early history.
