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.
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 rover's multi-mission radioisotope thermoelectric generator has a mass of 45 kg (99 lb) and uses 4.8 kg (11 lb) of plutonium-238 oxide as its power source. The radioactive decay of plutonium-238, which has a half-life of 87.7 years, gives off heat which is converted to electricity —approximately 110 watts at launch. [ 37 ]
AST SpaceMobile is a publicly traded satellite designer and manufacturer based in Midland, Texas, United States. [4] [5] The company is building the SpaceMobile satellite constellation, a space-based cellular broadband network that will allow existing, unmodified smartphones to connect to satellites in areas with coverage gaps.

Multi-mission Modular Spacecraft, also known as the MMS, was originally designed by NASA to serve the largest array of functions for the space program possible to decrease the cost of space missions. [1] It was designed to operate in four distinct areas of missions. [1]
After the ban of nuclear weapons in space by the Outer Space Treaty in 1967, nuclear power has been discussed at least since 1972 as a sensitive issue by states. [8] Space nuclear power sources may experience accidents during launch, operation, and end-of-service phases, resulting in the exposure of nuclear power sources to extreme physical conditions and the release of radioactive materials ...
The advanced multi-mission operations system (AMMOS) is a common set of services and tools created by the Interplanetary Network Directorate, a division of the Jet Propulsion Laboratory, for use in JPL's operation of spacecraft. [1]
