The robotic exploration mission was launched on November 23, 2020 and after twenty-three days returned to Earth with samples of lunar soil and rock weighing 1,731 grams.

China’s Chang’e 5 probe has discovered the first “in situ” evidence of water on the moon’s surface, according to a Article – Commodity It was published this Friday in the journal Science Advances by researchers from the Chinese Academy of Sciences (CAS).

The text indicates that there is an instrument on board the landing craft of the Lunar Exploration Mission to the Asian country Spectrophotometry Ridges, rocks, and water were discovered for the first time on our planet’s natural satellite.

Thus, he revealed that the lunar soil at the lander’s landing site contains less than 120 parts per million (ppm) of water, which is about 120 grams of water per ton, while the light vesicular rock contains about 180 parts per million of liquid. , so it is drier than it is on Earth.

What did they discover?

Experts believe that it was the solar wind, carrying hydrogen in its stream, that caused the increased moisture on the moon’s surface. They also noted that the moon has become drier due to the emptying of its mantle reserves.

The samples returned are A granule mixtureWhether on the roof or under it,” he explained to the agency Xinhua Lin Honglei, a researcher at the CAS Institute of Geology and Geophysics and a co-author on the study. He explained, “But the probe” on the site “can measure the outer layer of the moon’s surface.”
