    The Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) is a type of Radioisotope Thermoelectric Generator developed for NASA space missions 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 MMRTG was developed by an industry team . advent of new generators based on dynamic energy conversion and alternative static conversion processes favors use of “RPS” as a more accurate term for this power technology. RPS were first used in space by the U.S. in Since that time, the U.S. has flown 41 RTGs, as a power source for 26 space systems on 25 missions.

A radioisotope thermoelectric generator (RTG, RITEG) is an electricity generating device that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck generator has no moving parts.

RTGs have been used as power sources in satellites, space probes, and uncrewed remote facilities such as a series of. The isotopes Po and Pu meet these requirements. An energy conversion system with long life and high efficiency must be employed. No existing static conversion system can meet the efficiency required.

Two dynamic systems, Brayton and Stirling cycles, which have been under study recently, promise conversion efficiencies of about 20%.
