A New Fuel for Nuclear Power Systems Could Enable Missions to Mars and Beyond

To explore the unknown in deep space, millions of miles away from Earth, it's crucial for spacecraft to have ample power. NASA's radioisotope power systems (RPS) that rely on are a viable option for these missions and have been used for over 60 years. Now, NASA is testing a new type of RPS fuel that could become an additional option for future long-duration journeys to extreme environments.
