Abstract

There have been several spacecraft, induced surface glow observations and measurements that report radiation in the ultraviolet to visible spectral regions. This paper models a specific example of spacecraft glow where in-situ measurements were made on a small, clean satellite. The direct simulation Monte Carlo (DSMC) technique is used to model the formation of NO in the flowfleld of a 1- meter nose radius satellite from altitudes of 130 to 180 km. A new concept is developed for proper simulation of trace species in DSMC calculations. The DSMC"' simulations also modelled ambient trace species. The results show that sufficient NO is formed in the gas phase to explain the glow phenomena.
