NASA’s plutonium-238 supply crunch could limit future deep-space missions
A rare radioactive isotope stands between NASA and its next generation of deep-space exploration. Plutonium-238, the fuel ...
For decades, deep space exploration has depended on a handful of obscure isotopes quietly heating small nuclear batteries on robotic probes. Now a different, even less familiar element is moving to ...
Radioisotope power systems (RPS) keep spacecraft going with nuclear batteries. Until now, RPS operated using a plutonium isotope, but researchers have found that an isotope of americium could keep ...
Space missions depend on power systems that can function far away from sunlight and without maintenance. Solar panels ...
