Recently, the planetary science team of the Institute of Geology and Earth science of the Chinese Academy of Sciences, in cooperation with the Shanghai Institute of Technical Physics and the National Space Science Center, has obtained the water content under the in situ conditions of the lunar surface for the first time by studying the data of the "Lunar Mineral Spectroscopy Analyzer" carried by Chang'e 5. The latest research shows that there are about 120 grams of water in a ton of lunar soil and about 180 grams of water in a ton of rock. Combined with sample analysis, the vast majority of the water in the lunar soil comes from the contribution of the solar wind, and the extra water in the rock may represent the water inside the moon. According to the scientific research team, the water detected by the spectrometer refers to the water molecules or hydroxyl groups in the minerals, which can be converted into drinkable water under certain conditions.
