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 from a chemical reaction when hydrogen ions emitted from the sun — transported to the lunar surface from solar winds — combined with oxygen atoms inside the beads. The water-filled beads are tiny, ranging from “tens of micrometers to a few millimeters.” Still, there are enough on the Moon’s surface to (theoretically) supply an estimated 270 trillion kilograms of water — enough to fill 100 million Olympic-sized swimming pools.However, scientists haven’t yet figured ou
