Meanwhile, China has successfully landed a spacecraft on the far side of the moon, and samples brought back from its 2020 mission have revealed a new source of water that could be used in future explorations. “Water was embedded in tiny glass beads in the lunar dirt where meteorite impacts occur,” according to a recent Associated Press story. While mining these beads might be a challenge and their water content is minuscule, they do exist in vast numbers and could yield a substantial amount of H20.
