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 Energy. The MMRTG was developed by an industry team of Aerojet Rocketdyne and Teledyne Energy Systems.
The MMRTG is powered by 8 Pu-238 dioxide GPHS modules, provided by the Department of Energy. Initially, these 8 GPHS modules generates about 2 kilowatts thermal power.
The MMRTG design incorporates PbTe/TAGS thermoelectric couples from Teledyne Energy Systems. The MMRTG is designed to produce 125 W electrical power at the start of mission, falling to about 100 W after 14 years. With a mass of 45 kg the MMRTG provides about 2.8 W/kg of electrical power at beginning of life.
The MMRTG design is capable of operating both in the vacuum of space and in planetary atmospheres, such as on the surface of Mars. Design goals for the MMRTG included ensuring a high degree of safety, optimizing power levels over a minimum lifetime of 14 years, and minimizing weight.
This MMRTG is built from 8952 individual pieces that can be remodeled, deleted, UVW'ed or moved to suit your specifications. All parts of the MMRTG are present, including all exterior and interior parts, and was carefully modeled with great detail. The first image in the gallery shows the body, divided into two sides, which can be hidden to expose the interior components.
Mapping and Materials
No mapping is included, because this model can be shaded or colored with basic materials, such as stainless steel, aluminum, and white paint. If you are using Maxwell as your renderer, all materials are applied and ready for rendering.
