Advanced Stirling Radioisotope Generator

From Wikipedia, the free encyclopedia

The Advanced Stirling Radioisotope Generator (ASRG) is a radioisotope power system utilizing Stirling power conversion technology currently being developed under joint sponsorship by the United States Department of Energy and NASA for potential future space missions. The higher conversion efficiency of the Stirling cycle compared with that of radioisotope thermoelectric generators (RTGs) used in previous missions (Viking, Pioneer, Voyager, Galileo, Ulysses, Cassini, and New Horizons) offers the advantage of a four-fold reduction in PuO₂ fuel.
