Earth satellite loses annually about 200 tons of water because of the meteor attacks.

So, in the view of visionaries, looks LADEE watching the bombardment of the moon by meteorites
The study was conducted on the basis of data obtained during the mission, an orbital lunar probe Lunar Atmosphere and Dust Environment Explorer), launched in November 2013. For the first six months of its operation there have been a number of bursts in the number of particles ejected from the moon’s surface into interplanetary space. Among them were particles of water.
29 of the 39 bursts occurred within 48 hours during the period attributable to the maximum activity of the meteor showers Leonids, Geminids and Quadrantids. More powerful was the flow, the more particles out to space from the surface of the satellite.
The volume of water recorded by the sensors of the orbital probes were too large to consider them, for example, delivered by meteorites. Researchers believe that the most appreciable volumes of water were broken particles from granules of the lunar soil in the area of places of falling of meteorites.
During the year the meteors knocked out of the ground about 300 tons of water. A third of this volume returned to the surface (in particular in the polar regions); thus, given the cyclical nature of meteor showers, the Moon annually could lose up to 200 tons of water just because natural cosmic bombardment.
The full results of the study published in the journal Nature Geoscience.
