Abstract:
Magellan electronics bays ran 20 degrees C. hotter in flight than was anticipated. Contaminants were believed to have off-gassed in flight and accumulated on the thermal tiles, thus increasing solar absorptance. Evaluate vacuum outgassing procedures, and demonstrate system operation at temperatures beyond those expected in flight. For missions to inner planets, the spacecraft system thermal control design should minimize or avoid solar exposure on critical thermal control surfaces.
