Target entity: Multi-Mission Radioisotope Thermoelectric Generator
Context triple: [Perseverance, powerSource, Multi-Mission Radioisotope Thermoelectric Generator]
  • A. MMRTG chosen
    The MMRTG (Multi-Mission Radioisotope Thermoelectric Generator) is a long-lived nuclear power system that converts heat from decaying plutonium into electricity for spacecraft and planetary rovers like Curiosity.
  • B. TRW spacecraft bus
    The TRW spacecraft bus is a satellite platform developed by TRW that provides the structural support, power, propulsion, and control systems for space observatories and other spacecraft.
  • C. Voyager 1 electrical power subsystem
    The Voyager 1 electrical power subsystem is the spacecraft’s radioisotope thermoelectric generator–based system that supplies and manages electrical power for all onboard instruments and systems throughout its deep-space mission.
  • D. K-West Reactor
    K-West Reactor is one of the plutonium production reactors at the Hanford Site in Washington State, historically used to support the U.S. nuclear weapons program.
  • E. X-10 graphite reactor
    The X-10 graphite reactor was an early nuclear reactor at Oak Ridge, Tennessee, built during the Manhattan Project as a pilot plant for plutonium production and a key step toward the development of nuclear weapons and nuclear energy.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
