Modeling Electrostatic Levitation of Dust Particles on Lunar Surface
This paper presents a simulation model on electro-static levitation of lunar dust particles in the lunar terminatorregion. Full-particle particle-in-cell simulations are carried outusing real ion to electron mass ratio to obtain plasma sheath,surface charging, and the transition point of surface electric field.Test particle simulations are carried out to simulate the levitationof dust particles from lunar surface. Results show that the dust lev-itation condition in the terminator region is sensitively influencedby the ambient plasma condition and surface charging, and thelevitation altitude varies significantly even for small changes of thesun elevation angle.
