China discovers signs of water on the moon’s surface

In a research paper published in the journal “Nature” this week, scientists said that they analyzed the solid remains of lava that an unmanned Chinese mission excavated from the plain known as the “Storm Ocean” and found evidence of water in the form of hydroxyl encapsulated in a crystalline mineral known as apatite. .

Hydroxyl, which consists of one hydrogen and one oxygen versus two hydrogen and one oxygen atom in a water molecule, has also been found in samples extracted by NASA decades ago.

It was widely believed that most of the water on the Moon was the result of chemical processes caused by the explosion of charged particles from the Sun on the Moon’s surface.

And Reuters quoted the scientists, as saying that the source of the hydroxyl found in minerals such as apatite is very likely to be original.

They added: “The hydroxyl contents of the foreign materials resulting from the collisions may be negligible.”

According to the scientists, the Chinese units indicate that little or none of the hydroxyl in them was from “external sources”.

The Chinese Chang’e-5 mission returned to Earth 1,731 grams of samples in December 2020 after extracting soil and rocks from a previously unvisited part of the Okeanus Brucellarum plain.

China is expected to send more lunar missions without astronauts in the coming years, and one of its goals will be the study of water.

The presence of water on the moon could shed more light on the evolution of the solar system. It can also point the way to the site’s water resources, which is vital to any long-term habitation of humans.

And the sources of water distribution on the moon is still an unanswered question, according to scientists.
