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.
Silicon-germanium (SiGe) thermoelectrics have been used for converting heat into electrical power in spacecraft designed for deep-space NASA missions since 1976. This material is used in the radioisotope thermoelectric generators (RTGs) that power Voyager 1 , Voyager 2 , Galileo , Ulysses , Cassini , and New Horizons spacecraft.
Aerojet Rocketdyne is the prime contractor to the US Department of Energy for the Multi-mission Radioisotope Thermoelectric Generator. The first flight MMRTG is currently powering the Mars Curiosity Rover, and a second flight unit powers the Perseverance Rover. [citation needed]

This is a complete list of multinational corporations, also known as multinational companies in worldwide or global enterprises. These are corporate organizations that own or control production of goods or services in two or more countries other than their home countries.
Radioisotopes Production Facility (RPF) is located at the Nuclear Research Center in Inshas, near ETRR-2 research reactor and Fuel Manufacturing Pilot Plant (FMPP) as the three facilities share the same auxiliary services with high degree of integration between ETRR-2 and RPF to ensure safe transfer of the irradiated targets for radioisotope production.
