In October 2020, NASA announced with great fanfare that water had been discovered on the Moon. Neither one nor two, the press then seized on this information, distorting it at the same time.
Because NASA’s discoveries were still only preliminary. On the ground, space missions had to confirm the theories and other analyzes of the American space agency. Finally, after more than a year of waiting for the scientific community, it is finally, ironically, the Chinese competitor (CNSA) which with its Chang’e 5 probe has provided NASA with the precious answer.
How the water came to our nocturnal star ?
Now that the presence of water on the surface of the Moon is no longer lacking (or almost), the big question is to know how this water could end up there. According to CNSA scientists who deliver their conclusions in an article published in the journal Science Advances, water would have arrived on the Moon because of the solar wind.
In fact, hydrogen particles traveled to the heart of this stellar wind before coming to rest on the Moon. Once deposited on the surface of our satellite, the hydrogen met the oxygen there, thus forming molecules of water (H2O) and hydroxyl (OH). This idea had already been developed by NASA researchers in 2018 and 2020 when the American space agency found traces of water on the Moon.
