“…GEO orbits not only contain a substantial amount of low-temperature plasma but are also exposed to high-flux thermal plasma generated by solar storms, geomagnetic storms, geomagnetic substorms, and other activities. The danger is especially pronounced in the extreme conditions induced by geomagnetic substorms, where particles with energies ranging from a few to several hundred keV are present [13]. In order to provide a more accurate depiction of the plasma environment in the GEO orbit, it is necessary to employ a double Maxwell distribution.…”

This article aims to conduct an in-depth investigation into the environmental impact of Hall thruster plumes on spacecraft surface charging. The non-uniform plasma plume generated by Hall thrusters may trigger charging and discharging effects, making the assessment of surface charging risks crucial. Through numerical simulations using SPIS system, this study evaluates the surface charging characteristics of a complex spacecraft in orbit, simulating the effects of turning on and off the thrusters, as well as varying distances between the thrusters and the spacecraft. The simulation demonstrates that turning on the thrusters significantly affects spacecraft charging, reducing the potential difference between spacecraft surfaces from 3740 V to 19.2 V, effectively alleviating electrostatic discharge on the spacecraft surface. The closer the thruster is to the spacecraft, the more CEX ions are collected on the surface, influenced by the beam ions, resulting in a surface potential change of 1.3 V, with minor effects on surface potential but contributing to increased deposition contamination on the spacecraft surface.

“…The electron emission and transport properties of materials are key parameters in determining the likelihood of deleterious spacecraft charging effects [7,33,36,37] and are essential in modeling these effects with engineering tools such as the NASA NASCAP-2K [38][39][40], SPENVIS, and MUSCAT [41] codes. The SUSpECS studies of electron emission and resistivity will extend more than a decade of research in the field by the USU MPG [3,[6][7][8][9][10][11][12][13]19,40,[42][43].…”

The effects of prolonged exposure to the LEO space environment and charge-enhanced contamination on optical, thermal, and electron emission and transport properties of common spacecraft materials have been investigated by comparing pre-and post-flight characterization measurements. The State of Utah Space Environment and Contamination Study (SUSpECS) deployed in March 2008 on board the Materials International Space Station Experiment (MISSE-6) payload, was exposed for ~18 months on the exterior of the International Space Station (ISS), and was retrieved in September 2009. A total of 165 samples were mounted on three separate SUSpECS panels on the ram and wake sides on the ISS. Some samples, particularly those exposed to atomic oxygen in the ram direction, showed pronounced effects due to exposure. Biased samples for the charge-enhanced contamination study showed subtle variations in visible and infrared reflectivity.

“…Dielectric surfaces on the satellites, typically the solar panels, are subject to charging that leads to highly localized potential buildup that is subject to vacuum arcing damage. The differential charge-up and discharge of these surfaces are intrinsically kinetic phenomena that can only be analyzed with a particle approach to understand the role of different panel interconnect and insulation options and optimization of the satellite exterior design to mitigate such charge-up damage [5].…”

This paper presents recent progress on the development of the new multi-purpose particle modeling and simulation tool VizGrain. A unique aspect of VizGrain is that it allows computational modeling of particle dynamics in a variety of systems, including rarefied gas dynamics, macroscopic particle dynamics (e.g., dust particles, droplets, etc), particle-in-cell modeling, and hybrid continuum-particle modeling within a single integrated framework. VizGrain allows working with atomic sized particles and particles with finite macroscopic sizes. The former approach is used to model rarefied gas dynamics and conventional non-equilibrium plasmas, while the finite sized macro-particles are considered for the modeling of dusty plasmas, aerosols, droplets etc. In this latter case, the electrical charge up of particles in a plasma environment is considered. The model features a comprehensive variety of drag forces that can act on both atomic and macro-particles. A detailed description of the physical models implemented within VizGrain is presented, to provide insights into the approach that can be taken in other particle-based codes in the community. These models are scrupulously validated against the benchmark problems proposed in the research literature for a variety of applications from the plasma reactors used in semiconductor industry to high-speed rarefied gas dynamics problems.
