Scientists have discovered a new and renewable source of water on the moon for future explorers in lunar samples from a Chinese mission. Water was embedded in tiny glass beads in the lunar dirt where meteorite impacts occur. These shiny, multicoloured glass beads were in samples returned from the moon by China in 2020. The beads range in size from the width of one hair to several hairs; the water content was just a miniscule fraction of that, said Hejiu Hui of Nanjing University, who took part in the study.
