Micrometeorites collide with the moon at high speed and send shock waves that are reflected through the moon. the surface. They need to penetrate only a few centimeters to lift the water deposits, and the high energy of the collision converts the molecule into a water vapor. Loop breaks into space. Most of the molecules dissipate in a very thin atmosphere around the Moon, and some settle back into the ground.
The main author of the study was Mehdi Benn, a planetary scientist in the NASA Center for Space Flight. He said the CNN breakthrough "provides a great piece of the puzzle" about what happens when meteorites are faced with other "airless bodies" around our solar system and beyond.
This shows that water is not just blocked
Scientists believe that meteorites can raise lava water deposits. Now they know for sure
Benn, who also serves as a planetary scientist at the University of Maryland-Baltimore, reported that water is widespread "globally" on the moon. But much we do not know about his behavior day by day.
He summoned colleagues to combine data collected by the Neutral Mass Spectrometer on board the Lunar Atmosphere and the Lumber Explorer (LADEE), a robotic mission that rotated the Moon.
Previous lunar probes, such as Cassini and Deep Impact, showed "the existence of an active water cycle on the moon," written by Benny and his co-authors. They decided to study 33 water plumes on the surface, 29 of which were known and four were new.
Scientists knew that the water plumes correspond to the time when meteorite streams were present. And computer molecules predicted that meteorites could cause these water loops.
But the Benny team was able to see something that had not been confirmed before.
And because scientists have confirmed this on an airless body, they can now conclude that this process is happening everywhere, said Benn.
Although water is widespread in the lunar soil, it is very common. The moon is pretty dry. One metric ton of regolith (a layer of loose soil and deposits that cover a solid rock on a lunar spring) gives only 16 ounces.
The study shows that the moon is not so quiet and deserted
When showing that the moon is just a static layer, studies similar to this give us a new portrait of the moon, like a rocky world, living with dynamic geological and chemical processes .
Benn said he remembers how he looked at the moon as a boy, and thought of a distant, long orbit as "quiet and deserted." research tells him, and millions of boys and girls, another story.
"What excites me," Benn said, that the study shows changes in the moon, reacting on its heavenly outskirts not in order of decades or centuries, but "for a few days or even hours."
"The views are deceiving," said Benn. "The moon is active."
