These values for the 0 + H 2 0 total cross section are very close to those derived in the analysis of observations involving the Russian space station Mir [ 11]. velocity, derived from [10].…”

“…One more evidence that favors reaction (8.1) is that OH(A→X) glow was observed when the motor fired against the atmospheric wind, providing a decelerating impulse to the space vehicle (retro firing). No glow was observed during accelerating (direct) firings 6,36 . High endothermicity of reaction (8.1) explains this fact.…”

“…This uncertainty impeded exact interpretation of the UV-imager measurements and, generally, understated value of the experimental data. To resolve this uncertainty several attempts were undertaken to measure the glow spectra 6,7 . Most successful one happened on April 26, 2000 during the "Progress" de-orbiting.…”

Abstract. Approximate method for Monte-Carlo modeling of interaction of high-altitude engine exhaust plume with atmosphere has been developed. The method was applied for analysis of recent experimental data on Russian spacecraft Soyuz plume glow. In particular, sensitivity of computed glow radiation to the choice of elastic collision cross-section of atmospheric oxygen with plume molecules and its reaction cross-section with water molecules in the plume is analyzed. Conclusions are made about these cross-sections values.
