The robotic exploration mission began on November 23, 2020, and twenty-three days later it returned to Earth with samples of 1,731 grams of soil and lunar rocks.

China’s Chang’e 5 study has found the first ‘in-situ’ source of water on the moon’s surface. Article Published this Friday in the journal Science Advances by researchers from the Chinese Academy of Sciences (CAS).

The text indicates the presence of a device in the lander of the Asian lunar exploration mission Measured spectral reflection Recolith and rock, and water was first discovered on our planet’s natural satellite.

Thus, the lunar soil at the landing site of the study is less than 120 parts per million (ppm), which is about 120 grams of water per ton, while the mild vesicular rock contains 180 ppm of fluid. , So they are much drier than the earth.

Experts believe that the solar wind caused more moisture on the lunar surface as it carried hydrogen in its current. They also point out that the moon is dry because the lunar crust removes reserve gas.

“Returned models a Granular composition, On the surface and below it, ”he explained to the company Xinhua Lin Honglei, researcher and co-author of the CAS Institute of Geography and Geophysics. “But an ‘in-situ’ study can measure the outer layer of the lunar surface,” he explained.

China’s robotic lunar research mission Chang’e 5 Opened Landed on November 23, 2020 and December 1 of the same year. Twenty-three days later, he returned to Earth to study samples of soil and lunar rocks – weighing 1,731 grams.
