The existence of molecular H2O and evolution of solar wind–derived water on the lunar surface remain controver-sial. We report that large amounts of OH and molecular H2O related to solar wind and other multiple sources arepreserved in impact glasses from Chang’e-5 (CE5) lunar soil based on reflectance infrared spectroscopy and na-noscale secondary ion mass spectrometry analyses. The estimated water content contributed by impact glasses toCE5 lunar soil was ~72 ppm, including molecular H2O of up to 15 to 25 ppm. Our studies revealed that impactglasses are the main carrier of molecular H 2O in lunar soils. Moreover, water in CE5 impact glasses provides a re-cord of complex formation processes and multiple water sources, including water derived from solar wind, depos-ited by water-bearing meteorites/micrometeorites, and inherited from lunar indigenous water. Our study providesa better understanding of the evolution of surficial water on airless bodies and identifies potential source andstorage pathways for water in the terrestrial planets.
