(12 February 2021 – Aerojet Rocketdyne) Aerojet Rocketdyne lately acquired a contract award to ship as much as two Multi-Mission Radioisotope Thermoelectric Turbines (MMRTG) to the U.S. Division of Vitality (DOE) to be used in future planetary science missions.
MMRTGs are radioisotope energy techniques which have been used as dependable electrical energy sources on a number of deep area missions, together with NASA’s Perseverance Rover, which can land on Mars on Feb. 18.
Each MMRTGs will likely be fabricated and examined by Aerojet Rocketdyne and its teammate Teledyne Vitality Programs previous to supply to DOE’s Idaho Nationwide Laboratory, the place the items will likely be fueled and readied for launch primarily based on mission timelines.

“Whereas the particular missions every unit will help haven’t but been decided, the MMRTG is effectively fitted to quite a lot of environments,” stated Aerojet Rocketdyne CEO and President Eileen P. Drake. “The MMRTG is multi-mission succesful, that means that it will possibly function on the floor of planets and moons in a planetary environment or within the vacuum of area.”
The MMRTG produces reliable electrical energy by changing the warmth from plutonium 238 radioactive decay into electrical energy. A single unit can present dependable, long-lasting electrical energy to a spacecraft or planetary rover, enabling exploration of the deepest corners of the photo voltaic system, the place the good distance from the Solar dramatically reduces the effectiveness of photo voltaic arrays.
The MMRTG will energy NASA’s Dragonfly mission to discover Saturn’s moon Titan, and is being thought of for the Trident mission to discover Neptune’s largest moon Triton, which is believed to have a liquid ocean.
