Lunar exploration is in a period of expansion, with multiple nations launching missions and planning to return humans to the lunar surface and orbit. This increased activity raises concerns about orbital congestion, collision risk, and debris management. In addition, spacecraft orbiting the moon are exposed to highly variable plasma environments, increasing the risk of electrostatic discharges. Electrostatic actuation techniques proposed for Geosynchronous Earth Orbits applications can be extended to cislunar space to mitigate debris. To determine electrostatic forces, previously validated touchless potential sensing techniques can be used to determine the potential of a target debris object while also providing insight into discharge risk and lunar dust behavior.Electron based touchless potential sensing methods have been analyzed in previous studies, and a key limitation is the difficulty in detecting electron emissions. Furthermore, interactions in the solar wind such as Debye shielding and barrier formations have not been considered. Simulation tools are used to generate strategies to increase the observability of electron emissions and characterize the impact of cislunar spacecraft-plasma interactions on touchless potential sensing. These results also benefit cislunar missions with instruments or components sensitive to the plasma environment.Experimental methods to simulate flowing plasma and spacecraft wakes in the ECLIPS vacuum chamber are developed and used to validate a simple model of spacecraft wake formations around single and multiple spacecraft. Additional proximity interactions such as sheath overlap and electron emission recollection are shown to impact charging and electrostatic forces. Simplified approximations of the interactions are proposed to enable efficient charging analysis applicable to any system with multiple charged components.
