Water trapped in tiny glass beads on the Moon could hydrate future settlements

China's Chang'e 5 rover has found tiny glass beads containing water in an impact crater on the Moon. Samples collected from a 2020 mission found beads with water content as high as 2,000 parts per million (PPM). Given the prevalence of these glass spheres on the lunar surface, there may be enough to provide 71 trillion gallons of water. Some beads formed when asteroids collided with the Moon millions of years ago, while others came from ancient volcanoes. Scientists believe the water originated ...
