摘要

For more than fifty years, the Department of Energy (DOE) and its predecessor agencies have designed, built and delivered radioisotope power systems (RPS), powered by the decay heat of ~(238)Pu, to enable scientific and national-security missions in harsh environments where other power sources are infeasible. The accomplishments of the NASA missions that have used DOE-provided RPS have changed our understanding of the solar system, and continue to do so. Missions from Viking to Curiosity have broadened our understanding of the Martian climate, terrain, and potential for past habitability. The next nuclear-powered Mars rover, planned for launch in 2020, will continue to enhance our understanding of the Red Planet. The Voyager probes provided our first glimpses of many neighboring planets and moons, and nearly forty years after their launch are still charting new territory on their journey into interstellar space. These are just a few of many examples selected from decades of solar system discovery enabled by RPS and the suite of earth-based capabilities that make them available.
