Glass beads spawned in violent impacts from space rocks on the lunar surface have been found to have water trapped inside, offering what scientists describe as a potential reservoir of this precious resource for future human activities on the moon.
Scientists said on Monday an analysis of lunar soil samples retrieved in 2020 during China's robotic Chang'e-5 mission showed that these spheres of glass - rock melted and cooled - created in the impacts bore within them water molecules formed through the action of the solar wind on the moon's surface.
