Abstract

Predicting emissions under rarified flow conditions remains a challenge. Two rocket experiments (at 3.5 and 5 km/s) obtained the UV data under flight conditions using onboard instruments; the greatest discrepancies in the predictions occurred at the higher altitudes. An additional experiment is being planned to extend the velocity to 7 to 8 km/sec using instrumentation onboard a small satellite with a highly elliptical orbit. Scanning spectrometers and photometers will observe the periodic bow shock interactions. The periodic bow shock re- immersion to low altitudes (200 to 120 km) coupled to the orbital decay of the satellite, provide an opportunity to progressively map a broad region of rarified aerodynamics. The paper discusses the flight regime of the planned experiment, provides examples of the anticipated phenomena and calculations, and gives an indication of the preliminary sets of instruments and measurements planned.
