The Enigma of Lunar Dust Transport

摘要: We will review the highly contrasting points of view regarding ability fine dust grains to become transported in near-space lunar environment. While Surveyor and Apollo camera images suggest presence a horizon glow that has been provocatively interpreted as levitated and/or lofted dust, there is geological evidence indicate surface regolith not moved substantial way. electric forces have suggested driver for grain dynamics, recent detailed modeling near-surface non-monotonic potentials would could get large heights. lofting models require submicron hold/contain 100's elementary charges, it can be shown analytical1y residing on flat an extremely low probability having even single electron its surface, Can these diametrically opposing viewpoints reconciled? pros cons both sides. UVS LDEX instrument LADEE provide key new insights transport at Moon.
