Experimental study on electrostatic migration of different mineral particles composing lunar dust under electron irradiation

Dust electrostatic migration is one of the primary causes dust events on surface airless celestial bodies, which can result in multiple phenomena, including lunar horizon glow and pools, also offer crucial insights into evolution materials bodies. To date, characteristics laws are still not well understood. Here, we report pyroxene, olivine, ilmenite particles measured by laser Doppler method compare them with findings anorthite previous experiments to recognize differential different mineral components dust. The results demonstrate that particle sizes most moving pyroxene olivine range 0–10 μ m , their vertical velocities typically less than 2 s −1 consistent studies. cohesive force between probably what difference rates various insulating minerals. Note no were detected due material’s good conductivity. It be speculated concentration fugitive mare affected content, but further research needed determine how low content cause migration.
