Spacecraft Interactions as Influenced by Thermochemical Considerations
Abstract
Spacecraft in low Earth orbit undergo harsh environmental interactions that sometimes resemble the phenomenon observed in high-temperature vaporization and oxidation. For example, it has been reported that an osmium surface is removed, and surfaces of aluminum, silver, copper, iridium, niobium, nickel, and tungsten, are oxidized, even though the surface temperature when the measurements are made is -250 K. Similar results are observed for the case of nonmetallic samples, e.g., graphite and synthetic organic material, which are removed quickly. The purpose of this paper is to examine the data from the space experiments in light of thermochemical data and to consider possible implications or insight that may be gained for planning future experiments.
