Atmospheric environment for Space Shuttle (STS-31) launch

Abstract

A summary of selected atmospheric conditions observed near space shuttle STS-31 launch time on April 24, 1990, at Kennedy Space Center, Florida, are presented. Values of ambient pressure, temperature, moisture, ground winds, visual observations (clouds), and winds aloft are included. The sequence of pre-launch Jimsphere-measured vertical wind profiles is also presented. The final atmospheric tape, which consists if wind and thermodynamic parameters versus altitude, for STS-31 vehicle ascent was constructed. The STS-31 ascent atmospheric data tape was constructed to provide an internally consistent data set for use in postflight performance assessments and represent the best estimated of the launch environment to the 400,000 feet altitude that was traversed by the STS-31 vehicle.
