NASA selects reactor concepts for deep space exploration

Three reactor design concept proposals for a nuclear thermal propulsion system for deep space missions have been selected by the US National Aeronautics and Space Administration and the Department of Energy. The reactor will be a critical component of a nuclear thermal engine, which would utilise high-assay low-enriched uranium fuel.

NASA marks 60 years of nuclear power in space

NASA has marked the 60th anniversary of the launch into space of its first nuclear-powered satellite. Transit IV-A - an experimental navigational satellite with a radioisotope-powered generator - was launched by Johns Hopkins University Applied Physics Laboratory from Cape Canaveral on 29 June 1961, and NASA has since flown more than 25 missions carrying a nuclear power system.
