Scientists suspect that identical beads may exist on other moons in our Solar System. Our direct measurements of this surface reservoir of lunar water reveal that impact glass beads may store significant amounts of solar wind-derived water on the moon and imply that impact glass may be water reservoirs on other airless worlds,” concluded the study’s authors. “The presence of water in impact glass beads is compatible with distant detection of water in lower-latitude areas of the Moon, Vesta, and Mercury.” Our findings indicate that the impact glasses on the surface of Solar System airless bodies are capable of storing solar wind-derived water and releasing it to space.”
