The Atmosphere and Ionosphere applications are similar in scope, as they both evolved from the Atomic Oxygen (AtomOx) application within the original ESABASE, which is concerned with particles (mostly O1) that accumulate on the surfaces of a spacecraft.
To analyse a spacecraft with respect to the configurable Atmosphere and Ionosphere application models, users can apply different materials to the spacecraft’s surfaces.
