AbstractThe upper Martian atmosphere mainly contains carbon dioxide (CO2) and atomic oxygen (AO) depending on the altitude. Spacecraft orbiting in the Martial upper atmosphere encounters high-energy collision with these molecules. In order to evaluate a risk of material erosion possibility in Martian orbit, a method for ground-based Martian atmospheric simulation was investigated. A laser-detonation hyperthermal beam source was applied and a new pulsed supersonic valve (PSV) system was developed for the Martian atmospheric simulation experiments. Two PSVs were equipped with a nozzle in order to increase freedom of formation of hyperthermal beam with mixture of two types of gases. It is expected that two molecular beams are formed individually with this system.
