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. This type of generator has no moving parts and ...
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.
Rubber tyred gantry crane. A rubber tyred gantry crane (US: rubber tired gantry crane )/ RTG ( crane ), or sometimes transtainer, is a wheeled mobile gantry crane operated to ground or stack intermodal containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels.
Radioisotope rocket. A radioisotope rocket or radioisotope thermal rocket is a type of thermal rocket engine that uses the heat generated by the decay of radioactive elements to heat a working fluid, which is then exhausted through a rocket nozzle to produce thrust. They are similar in nature to nuclear thermal rockets such as NERVA, but are ...
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. ...
MHW-RTG. 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] Radioisotope thermoelectric generators for the Voyager program.
The Beta-M contains a core made up of strontium-90, which has a half-life of 28.79 years. [2] The service life of these generators is initially 10 years, and can be extended for another 5 to 10 years. [1] The core is also known as radioisotope heat source 90 (RHS-90). In its initial state after manufacture, the generator is capable of ...
