A Chinese mission confirmed the presence of water on the Moon on its surface

While the presence of water on the Moon had already been confirmed by orbital observations and analysis of samples, a measurement Besides Now added to the list of evidence. It will remain to specify the exact nature and origin of this water.

The Chinese space agency invites us to relive the landing of Chang’e 5 on the visible face of the Moon on December 1, 2020. The lander landed in the storm’s ocean for an express sample collection mission. This is the first time in more than 40 years that lunar rocks have been brought back to Earth.

there is water on Moon, There are some who still doubt it today, as evidenced by orbital observations and analysis of samples. At the end of 2020, NASA also confirmed the presence of molecules of water (H20) on the surface of our satellite. still no solution Besides It was not possible till now. But we must speak in the past because it has happened now. thanks to’Chinese lander Chang’e 5,

In December 2020, it was posed on the moon, north of the ocean storm, on one of basalt The youngest – the site is still about two billion years old – from our satellite. With the main objective of taking samples and bringing them back to Earth. But before he had time to speak his mind spectrometer Lunar Minerals (LMS) on the surrounding regolith.

Valuable result, but to be specified

It is the instrument that made it possible to determine the water content of rocks located in the lander’s field of vision. Using spectral reflectance measurements, the researchers were able to calculate that the regolith in some regions may contain as much as 120 parts per million (ppm) of water – such as hydroxyl (OH) or water molecules, Whereas one rock they also analyzed had a little more in it. Around 180 ppm.

Researchers show thathydrogen The water required for manufacturing there can be brought by solar wind, rock, it may well come from a unit Basalatic old and being thrown there. Its relatively high water content suggests a source hidden beneath the surface. And if the analysis OH and H. do not make it possible to discriminate2Hey, they remain consistent with the initial analysis of the samples reported by Chang’e 5,
