Scientific paper

A thermal control system of the Magellan spacecraft launched on May 4, 1989 to perform radar mapping and other science experiments is described. The thermal control system design required sustained operations near Venus in a three-axis stabilized spacecraft. It is concluded that, despite the constraints imposed by Magellan's thermal degradation, the primary mission goal of mapping at least 70 percent of the planet was far exceeded. Ninety-eight percent of the surface was imaged with unprecedented clarity by September, 1992. It is recommended that future three-axis stabilized spacecraft targeted to the inner planets strongly account for thermal designs using active cooling methods to maximize tolerance to degradation and to enhance design flexibility.
