The revelation about the “facelift” of the Moon

Much more often, than they thought it was the…
scientists up to now, bombarded τοφεγγάρι us from meteors and tiny meteors, with the result that created craters, but also “recycled” the surface at a very fast rate.
This causes the Moon to make a complete “face-lift” every 80,000 years ago, according to a new american scientific research, which is based on elements of the lunar satellite LRO of NASA, which “maps” the moon since 2009.
The constant falling meteors cave constantly the superficial loose layer (mostly dust) of the satellite of the Earth, the ρεγκόλιθο, at a depth of up to two centimeters, at a rate of at least 100 times faster than previous estimates.
At the same time, although most of the craters are very old, the asteroids that fall, each time make the Moon an average of 180 young craters with a diameter of at least ten meters. The rate of creation of new craters is by 33% bigger than up to now estimated. It is estimated that during the last seven years have been created on the Moon at least 222 young craters (the largest recently found, has a diameter of 43 meters).
The researchers, led by planetary scientist Emerson Σπέγιερερ of Πολιτιακού University of Arizona, who made the relevant publication in the journal Nature, compared more than 14,000 pairs of high-resolution photos of the same areas of the moon, drawn by the satellite Lunar Reconnaissance Orbiter (LRO) in different time periods and covering almost 7% of the total lunar surface.
The Earth receives a similar bombardment by tiny meteors, but protected by the dense atmosphere. On the contrary, the Moon has an extremely thin atmosphere, receives a massive “hit”. The earth’s atmosphere can dissolve even meteorites with a diameter of 25 meters, which otherwise would fall to our planet, and now are dispersed by explosion in a big or sometimes smaller height (such as in Chelyabinsk).
The discovery that the Moon receives more frequent “hits” from above, from meteors traveling with a speed of 500 meters per second, creates increased concerns about the risks of future manned missions to our moon, as well as the ambitious plans for the creation of a lunar base or “the village”.
