The 24 pages that link to Radioisotope thermoelectric generator, each with the reason it gives.

• Nuclear fissionCompared with: It provides nuclear-powered electricity without sustaining a fission chain reaction.

• Voyager 1Related: Voyager 1 relies on three generators to power its instruments and communications far from the Sun.

• RadioactivityBroader topic: It uses decay heat to power spacecraft and remote equipment without moving parts.

• Thermoelectric effectBroader topic: It demonstrates long-duration Seebeck power generation in spacecraft.

• Voyager 2Related: Its plutonium-powered generators supply Voyager 2 as sunlight grows too weak for solar panels.

• PlutoniumRelated: Plutonium-238 has powered these generators in spacecraft and other remote systems.

• Voyager programRelated: Its steady output powered the spacecraft far beyond the reach of sunlight.

• New HorizonsRelated: It supplied electricity far beyond the reach of practical solar panels.

• Thermoelectric generatorBroader topic: It powers spacecraft where long life and operation far from sunlight outweigh low conversion efficiency.

• Seebeck effectBroader topic: It maintains the temperature gradient with radioactive heat, enabling long-lived Seebeck power generation.

• AmericiumCompared with: Unlike plutonium-238, americium-241 is a possible long-lived heat source for future space power systems.

• Cobalt-60Compared with: Unlike heat-producing isotopes used for power, cobalt-60 is chiefly valued for its gamma radiation.
