Apollo 15 Glass Beads Reveal Lunar Water, Challenging Dry Moon Assumption

During the Apollo 15 mission, astronauts observed unusual green flecks on the lunar surface. Subsequent analysis identified these as volcanic glass beads that trapped water. Researchers detected hydrogen within the beads, confirming the presence of lunar water. The discovery contradicts the long‑held belief that the Moon is extremely dry and suggests significant water reservoirs deep within its interior. This finding reshapes our understanding of the Moon’s geology and its potential for future exploration.
