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 thrusters may trigger charging and discharging effects, making assessment risks crucial. Through numerical simulations using SPIS system, this study evaluates characteristics a complex in orbit, simulating effects turning off thrusters, as well varying distances between spacecraft. simulation demonstrates that...
The Meridian Project’s sounding rocket mission uses a mass spectrometer to conduct in-situ atmospheric detection. In order assess the influence of surface material outgassing and attitude control jet on spectrometer’s detection, platform was modeled simulated. Using physical field simulation software COMSOL Monte Carlo method, this study investigated whether gas molecules from two cases could enter sensor sampling port after colliding with background atmosphere. results show that detection...
In this article, high spatiotemporal resolution data obtained by the atmospheric density detector carried China’s APOD satellite are used to study hemispheric asymmetry of thermospheric density. A detailed analysis is first performed on dual magnetic storm event that occurred near autumnal equinox 8 September 2017. The results show enhancement ratio in southern polar region (SPR) duskside was approximately 1.33–1.65 times northern (NPR), demonstrating a strong response during storm. However,...
