NASA’s new nuclear battery could run for 433 years

Spacecraft operating far from the Sun cannot rely on solar panels. For decades, NASA has used radioisotope power systems (RPS) powered by plutonium-238, which has a half-life of about 88 years. Now, researchers are testing americium-241 an isotope with a half-life of nearly 433 years as a potential fuel for the next generation of nuclear batteries.Radioisotope power systems generate electricity from the natural heat produced by the radioactive decay of isotopes. The heat is converted into electricity using free-piston Stirling converters. These converters have been tested to run continuously for over a decade with minimal wear, making them ideal for microgravity environments. Do you think that this will be realized ?
