An approach for modeling the infrared glow radiation about the Space Shuttle at low-earth orbit flight altitudes is examined. The study builds on the modeling and numerical techniques developed for Atmospheric Explorer. Due to the rarefied nature of the flow, the direct simulation Monte Carlo method is used. The study extends the earlier gas-phase reaction model to include NO vibrational-state-specific formation using cross sections derived from molecular dynamics. Infrared spectra are computed using the state specific NO vibrational levels and an accurate line-by-line spectral model. The affect of different surface accommodation models is also examined. Finally, simulated spectra are compared with IR data obtained from Shuttle space flight experiments.
