DOE's RTG is doing it again. The Department's Multi-Mission Radioisotope Thermoelectric Generator (RTG) is providing continuous power to the Mars rover Curiosity. The Multi-Mission RTG was constructed, assembled and tested by the Department and the Idaho, Oak Ridge, Los Alamos and Sandia National Laboratories. The RTG has supported many space missions, including the Apollo missions to the Moon, the Viking missions to Mars, and the Pioneer, Voyager, Ulysses, Galileo and Cassini missions to the outer solar system.
