Effects of Shuttle environment on instrument performance

Abstract

Examination of the OSTA-1 payload instruments carried in the shuttle bay during the 54.25 hour mission of STS-2 indicates that the shuttle environment has no measurable effect on the Earth-viewing experiments. Operation of the payload shows that flight simulations are essential and experiment replanning practice is needed. Ground control of experiments is desirable since malfunctions of totally automated experiments cannot be fixed in flight. Alarm limits for experiments must be realistic since the crew loses interest after a few alarms. The quality and number of hours of data obtained for each experiment are listed.
