For more than fifty years, radioisotope thermoelectric generators (RTGs) have been the United States’ main nuclear power source in space. RTGs offer many benefits; they are relatively safe and maintenance-free, are resilient under harsh conditions, and can operate for decades. RTGs are particularly desirable for use in parts of space where solar power is not a viable power source. Dozens of R… Web23 okt. 2024 · Office of Nuclear Energy Initiatives Space and Defense Power Systems Through a strong partnership between the Energy Department's office of Nuclear Energy and NASA, radioisotope power systems have been providing the …
