Glow Modeling Using the Integrated Spacecraft Environment Model

The Integrated Spacecraft Environment Model (ISEM) was developed to model the neutral molecular environment in the immediate vicinity of a spacecraft. The modeling methodology used in ISEM computes species specific parameters for collisional interactions induced by the spacecraft. The model provides a good starting point from which to model other induced phenomena such as spacecraft glow. As such, ISEM has been used to model several of the proposed ultraviolet glow mechanisms, and thereby provide a modeling test bed to help with glow studies and eventually make glow predictions for Space Station and other orbiting spacecraft.
