According to Geek.com. NASA’s Kilopower Project Could Enable Crewed Missions to Moon, Mars.
NASA, together with the Department of Energy’s National Nuclear Security Administration (NNSA), demonstrated a new nuclear reactor power system.
The experimental project began in 2015. A test reactor, dubbed KRUSTY (Kilopower Reactor Using Stirling TechnologY), was assessed between November 2017 and March 2018.
Small and lightweight, the Kilopower project could enable long-duration crewed missions to the Moon, Mars, and beyond.
