Lunar dust grains pick up electric charge from solar UV and plasma. This can levitate fine particles meters above the surface. Apollo astronauts reported “horizon glow,” likely caused by this dust. Dust sticks to equipment and suits due to static. Understanding this phenomenon is crucial for long-term missions. Electric dust movement can transport material across craters.
It matters for equipment longevity and astronaut safety. Dust contamination can degrade optics and machinery.
It also shows how microgravity and solar radiation interact uniquely. Dust levitation affects surface chemistry studies.
Lunar dust can cling to astronauts’ gloves like static cling.
