China’s Chang’e-2 Lunar Probe Lander has discovered the first on-site evidence of water in the Moon’s soil and rocks, providing new evidence of the satellite’s dryness. 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, according to a study published Saturday in the science journal Science Advances. and 150 ppm of water in a convective 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 rock and water on land. The device aboard the lunar lander tested regolith and rock and found water on the spot for the first time.
The state-run Xinhua News Agency quoted researchers from the Chinese Academy of Sciences (CAS) as saying that the amount of water absorbing water molecules, or hydroxyls, can be estimated at a frequency of about three micrometers.
According to the report, solar winds contributed most to the moisture on the lunar surface, as these solar winds carry hydrogen, which forms water, the researchers said. He said the additional 30 ppm of water in the rocks on the Moon’s surface could come from the Moon’s interior. The lunar probe is therefore likely to come from an older, more moist basaltic unit of rock ejected 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 reservoirs present beneath the surface. Chang’e-2 landed on the Moon at one of the youngest mer basalts in the mid-high latitudes. They measured the presence of water at the site and took samples weighing 121 grams. The returned samples were a mixture of grains on both the surface and the bottom. But the in-situ probe can measure the outer surface of the Moon, said Lin Hongle, a researcher in geology and geophysics under CAS.
“Creating a Moon-like surface condition on Earth is challenging,” Leno said. Therefore in-situ measurement is very important. Its results match those of the initial analysis of the Chang’e-Five samples. The mission’s research will provide further clues to China’s Chang’e-2 and Chang’e-2 missions.
