China's Chang E-2 lunar probe finds evidence of water in lunar rocks

Beijing, Dt
China's Chang E-2 Lunar Probe Lander has discovered the first on-site evidence of water in the lunar soil and rocks, providing new evidence of satellite dryness. According to a study published Saturday in the science magazine Science Advances, the lunar soil at the site where the Chang E-2 lunar probe landed is expected to contain 150 parts per million (ppm) of water, or 150 grams per ton of water, and 150 ppm of water in a vascular rock. Chances are. This place is drier than the earth.
Remote observations have previously confirmed the presence of water on the moon, but the spacecraft has now found signs of water in the rock and on the ground. The device on board the lunar lander tested the regolith and rock and, for the first time, found water on the spot.
Citing researchers from the Chinese Academy of Sciences (CAS), the state-owned Xinhua News Agency said that the amount of water can be estimated by absorbing water molecules or hydroxyl at a frequency of about three micrometers.
According to the report, solar winds contributed the most to the humidity on the lunar surface, as these solar winds carry hydrogen, which forms water, the researchers said. He added that an additional 30 ppm of water in the rocks on the lunar surface may have come from the interior of the moon. The lunar probe is therefore likely to have come from an older, more moist basaltic unit of rock extracted from the lunar surface. The study found that the moon had dried up within a certain period of time due to the absorption of gases from existing reservoirs below the surface. The Chang E-2 landed on the moon at one of the youngest mer basalts in mid-high latitude. He measured the presence of water at the site and obtained samples weighing 121 grams. The returned samples were a mixture of granules on both the surface and the underside. But the in-situ probe can measure the outer surface of the moon's surface, said Lin Honglei, a researcher with Geology and Geophysics under CAS.
"Creating a moon-like surface condition on Earth is challenging," Leno said. So in-situ measurement is very important. Its results match the preliminary analysis of Chang E-Five samples. The mission's research will provide further clues to China's Chang E-2 and Chang E-2 missions.
