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.
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.
Aerojet Rocketdyne is a subsidiary of American defense company L3Harris that manufactures rocket, hypersonic, and electric propulsive systems for space, defense, civil and commercial applications. [ 3 ] [ 4 ] [ 2 ] Aerojet traces its origins to the General Tire and Rubber Company (later renamed GenCorp, Inc. as it diversified) established in ...
This material is used in the radioisotope thermoelectric generators (RTGs) that power Voyager 1, Voyager 2, Galileo, Ulysses, Cassini, and New Horizons spacecraft. SiGe thermoelectric material converts enough radiated heat into electrical power to fully meet the power demands of each spacecraft. The properties of the material and the remaining ...
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. ...
One mission proposed using the electricity to power ion engines, calling this method radioisotope electric propulsion (REP). [18] A power enhancement for radioisotope heat sources based on a self-induced electrostatic field has been proposed. [21] According to the authors, enhancements of 5-10% could be attainable using beta sources.
