Unpublished discovery: “They find tons of water on the Moon” (Video)
Scientists have analyzed the samples collected by the Chang’e-5 probe on the Moon and have discovered some impact crystals that contain water inside
Two years after China successfully completed the Chang’e-5 mission. The probe reached the Moon and obtained the first samples from the satellite since the Soviet Lunik 24 mission in 1976.
The group of experts in charge of its analysis have shared their results. And it seems that they have found one of the great mysteries that the scientific community has been questioning about the Moon:
Where does the water it contains come from?
The samples collected by the Chang’e-5 probe, in the surroundings of Mons Rümker, are impact crystals that contain water inside.
These have “homogeneous chemical compositions and smooth surfaces,” the experts have specified. One of the main characteristics of the impact glass crystals used by the Chang’e-5 mission is the abundance of water they can retain:
Up to about 2,000 micrograms.g-1, with extreme deuterium depletion characteristics.
This was reported by experts from the Chinese National Academy of Sciences (CAS) —and the two European collaborators who have joined the project— in an article published this Monday in the journal Nature Geoscience.
They have also pointed out that the water contained in these crystals comes from the solar wind and that they “acted like a sponge to cushion the lunar surface water cycle.”
Professor Sen Hu of the Chinese Academy of Sciences, who led the research, said that these findings “indicate that impact crystals on the surface of the Moon and other airless bodies in the Solar System are capable of store water derived from solar winds and release it into space”.
Until now, the different missions destined to study the Moon had been able to confirm the presence of structural water or in the form of ice on the satellite.
However, with this new discovery, the scientific community already assumes that there may be multiple water reserves yet to be identified. And that these, in addition, have the capacity to retain water in the satellite and that it does not escape into space.
