Apollo Discovery: Tiny Beads Uncover Moon’s Volcanic History

Quick Summary

• Apollo astronauts discovered tiny, radiant orange glass beads on the Moon during their missions.
• These beads were formed 3.3 too 3.6 billion years ago through lunar volcanic eruptions, serving as “pristine capsules” of the Moon’s interior.
• A new study utilized advanced microscopic techniques to analyze these lunar beads,uncovering details about their mineral compositions and volcanic origins.
• Techniques used include NanoSIMS ion probe technology at Washington University and other methods like atom probe tomography and electron microscopy at partnering institutions.
• The analysis revealed how explosive eruptions shaped the Moon’s surface with distinct chemical compositions and eruptive styles over time,differing significantly from earth’s processes.
• Researchers preserved bead samples meticulously to avoid contamination by Earth’s atmosphere during their studies.
