Apollo 15 astronauts collected tiny green glass beads from the Moon in 1971; more than 35 years later scientists found evidence of water inside, changing what we knew about the lunar interior

• Representative Image (Image Credit: Canva)In 1971, Apollo 15 astronauts David Scott and James Irwin noticed something unusual on the Moon: tiny green flecks scattered across the otherwise grey surface.
• They collected samples and brought them back to Earth, unaware that the material would decades later challenge a long-held belief about the Moon.
• According to Brown University, the green flecks were volcanic glass beads, and more than 35 years after the mission, researchers discovered evidence of water trapped in the volcanic glass.
