The challenge posed by the need for autonomous repair of unmanned spacecraft in unattended environments in outer space is addressed. The redundancy philosophy which forms a fundamental design driver for recent JPL interplanetary spacecraft is reviewed, and the requirements for autonomous spacecraft operations are described. Autonomous fault detection and correction is discussed, and in-flight experiences with fault correction during the VO and VGR missions are described. The lessons learned from these experiences are reviewed.
