Researchers estimate that impact beads — created when an asteroid strikes the surface, leading to molten droplets that then freeze — could hold up to 270 billion tons of water.
Scientists revealed Monday that they have discovered a new “reservoir” of waterChina’s lunar lander Chang’e 5 found and collected several soil samples including impact glass beads that contained “substantial quantities” of water, according to a reportThe beads of glass are created when an asteroid strikes the surface of the moon and create molten droplets, which then freeze and join the soil and dust already accumulated on the moon’s surface, according to the researchers.
They estimate that the impact beads — spread across the moon’s surface — could be holding up to 270 billion tons of water. “The impact glass beads preserve hydration signatures and display water abundance profiles consistent with the inward diffusion of solar wind-derived water,” reads the study. While the specific origins of the lunar surface water remain “largely unknown,” the report does theorize about several potential sources that may have “contributed” to the water source, including: “ solar wind implantation, outgassing of volatiles during lunar volcanism, deposition of volatile-bearing pyroclastic deposits and minerals and delivery by impacts of comets and asteroids.”
