Charging Properties and Particle Dynamics of Chang’e-5 Lunar Sample in an External Electric Field

Engineering
Facing the challenges of in-situ utilization of lunar regolith resources, applying an external electric field to manipulate lunar particles has become a promising method for space particle control, which mainly depends on the particle charging properties

First Passive Permittivity Measurement of Lunar Regolith Simulant at Terahertz Band

The Planetary Science Journal
This study presents the first passive measurements of the relative polarization ratio (RPR) and apparent bulk permittivity (ABP) of lunar regolith simulants at approximately 280 GHz. We prepare anorthositic and basaltic simulants with both optically flat
