Geologists have studied grains of lunar soil from Chang'e-5.It turned out that their rim is characterized by a high concentration of hydrogen and a low deuterium/hydrogen (D/H) ratio. The data is consistent with the theory that “lunar water” appeared as a result of the influence of the solar wind on the surface of the Earth’s natural satellite.
The researchers modeled hydrogen retention inlunar soils at different temperatures. It turned out that water from the southwest could remain on the surface of the Moon in middle and high latitudes. At the same time, the study authors stated that polar lunar soils “may contain more water than the Chang’e-5 samples.”

"Chang'e-5" - Chinese automatic interplanetarya station launched as part of an unmanned return mission for lunar exploration. Like its predecessors, the mission's spacecraft is named after the Chinese moon goddess Chang'e.
According to earlier studies, the numberwater on the lunar surface varies depending on latitude and time of day (up to 200 parts per million). This noticeable difference suggests a rapid rate of desorption of the lunar surface.
