Thermal vacuum performance testing of the Space Shuttle Orbiter radiator system
A space shuttle orbiter system thermal vacuum performance test was conducted at NASA-Johnson Space Center in Chamber A of the space environment simulation laboratory. The test of objective was to verify the radiator system heat rejection performance capability utilizing two development and two flight radiator panels comprising one of the two Orbiter Freon-21 coolant loops. Radiator performance over the range of expected flight conditions was as predicted, and there was no degradation of performance after extended vacuum exposure.
