Web13 de abr. de 2024 · The use of nuclear power systems in space goes back almost to the start of ANS. In 1961, the Transit 4A satellite became the first U.S. spacecraft to be powered by a radioisotope thermoelectric generator (RTG). Combined with solar cells, RTGs have been used on the Moon and on satellites and to explore the solar system and beyond. Webuse in Radioisotope Heater Units (RHUs) to keep satellites warm and functioning in space, and in Radioisotope Thermal Generators (RTGs) to produce electrical power. More recently, plutonium-238 has been used instead of polonium. ##### 238. Pu has a much longer half-life but produces less power (0 W g–1).
