Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
The Multihundred-watt radioisotope thermoelectric generator (MHW RTG) is a type of US radioisotope thermoelectric generator (RTG) developed for the Voyager spacecraft, Voyager 1 and Voyager 2. [1] The Voyager generators continue to function more than 45 years into the mission. [2] Radioisotope thermoelectric generators for the Voyager program.
Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.
GPHS-RTG or general-purpose heat source — radioisotope thermoelectric generator, is a specific design of the radioisotope thermoelectric generator (RTG) used on US space missions. The GPHS-RTG was used on Ulysses (1), Galileo (2), Cassini-Huygens (3), and New Horizons (1). [1] The GPHS-RTG has an overall diameter of 0.422 m and a length of 1. ...
SNAP-11 was an experimental RTG intended to power the Surveyor probes during the lunar night. The curium-242 RTGs would have produced 25 watts of electricity using 900 watts of thermal energy for 130 days. The hot junction temperature was 925 °F (496 °C; 769 K), the cold junction temperature was 350 °F (177 °C; 450 K).

The core is also known as radioisotope heat source 90 (RHS-90). In its initial state after manufacture, the generator is capable of generating 10 watts of electricity . [ 3 ] The generator contains the strontium-90 radioisotope, with a heating power of 250W and 1,480 TBq of radioactivity – equivalent to some 280 grams (9.9 oz) of Sr-90. [ 4 ]
Alternatively, radioisotopes may be used in a radioisotope electric rocket, [1] in which energy from nuclear decay is used to generate the electricity used to power an electric propulsion system. The basic idea is a development of existing radioisotope thermoelectric generator , or RTG, systems, in which the heat generated by decaying nuclear ...
