The Moon's surface carries scars of eons of meteorite blasts, but these space rock strikes are also the key to a fantastic new discovery about our satellite: it expels water drops during the meteorite shower.
Researchers found that meteorite blasts throughout the moon's surface were strong enough to force tiny drops of water from the dusty lunar soil and the environment above.
"The surface of the moon that releases water is protected by a layer – a few centimeters – a dry ground that can only be violated by large micrometeoroids," says the planetary scientist at NASA and the University of Maryland Baltimore County, Mehdi Benna.
JUST: Scientists discovered were released during the Moon during the meteor shower! 💧🌑 This discovery provides a potential resource for future exploration, improves our understanding of Moon's previous geologic and continued evolution. Details: https://t.co/2zmOazTHL0pic.twitter.com/oONOrqHOBx

When small meteoroids enter the Months, the shockwave may force droplets of water to coat the lunar soil strips lying beneath the layer surface layer. Most impact crater materials are simply soaked and turn into space, but about one-third of the water forced by the meteorite strike falls down over the moon.
The water leak may be detected by sensitive NASA instruments on board the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft. By analyzing this data, the team understood a clear pattern between water and meteorite shower emissions.
Research means that traces of water values are spread over the entire surface of the Moon, which may have great interest and value for future space mining missions.
As the question goes from where the water comes from, the team said the possibility was that it would come from meteorites themselves: "We know that some of the water should come from Months, since the mass of water released is greater than the mass of water within the meteoroids coming in, " said the second research author, Dana Hurley of the Johns Hopkins University Applied Physics Laboratory.
Benna, the lead author of the study of water: "The water that was lost was probably ancient, either back to the formation of the Moon or deposited in its early history." ]
