【#Tech24H】Researchers from the Institute of Geology and Geophysics of the Chinese Academy of Sciences have proposed a three-stage model by analyzing plagioclase particles in the Chang’e-5 lunar soil to explain the behavior of rare gases on the lunar surface, including solar wind and cosmic ray injection, local thermal diffusion, and re-irradiation. This model indicates that solar wind injection and gas escape are interrelated processes: some light elements may be instantaneously released due to micro-damage in minerals upon impact, entering the lunar exosphere; micrometeorite impacts and diurnal temperature fluctuations further promote gas diffusion and escape, resulting in significant variations in gas content among different particles. This achievement is the first to unveil the key mechanisms of solar wind interaction with the lunar surface, providing new clues for understanding the distribution of lunar volatiles and solar evolution.
