Impact Glass Beads from the Moon Contain Solar Wind-Derived Water, Study Shows

If the Moon has enough water, and if it’s reasonably convenient to access, future explorers might be able to use it as drinking water or to convert it into hydrogen and oxygen for rocket fuel or oxygen to breathe. Image credit: NASA’s Goddard Space Flight Center.

Scientists from China and the United States have analyzed the impact glass beads from a lunar soil sample returned by China’s Chang’e-5 mission. Asteroid and comet impacts are the major exogenous processes that reshape the surface morphologies of airless bodies, as evidenced by the widespread presence of impact craters on the Moon, Mercury and asteroids. These impacts probably create impact glasses and glass beads on any airless bodies. He et...
