flag NASA uses "nuclear batteries" powered by plutonium to provide reliable electricity for deep space missions.

flag Radioisotope thermoelectric generators (RTGs), or "nuclear batteries," power spacecraft in deep space by converting heat from plutonium-238 decay into electricity. flag Used in missions like NASA's Curiosity and Perseverance rovers and the New Horizons probe, RTGs offer reliable power for decades, working effectively even billions of miles from Earth. flag They produce a few hundred watts of electricity, enough for long-term space missions.
