The United States flew a reactor in space in the 1960s and has studied nuclear thermal propulsion for decades. Fuel is not the primary limitation either; the enriched uranium supply chain is ...

Energy is fundamentally important—researchers have linked a lack of reliable energy to poor physical health, poor mental ...

Add Yahoo as a preferred source to see more of our stories on Google. Two United States based firms have entered into a partnership to advance high-power nuclear electric propulsion technology for ...

This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the chemically propelled rockets the agency develops now is called nuclear ...

Nuclear rockets are moving from Cold War concept to near-term hardware, and the shift could reshape how quickly and safely humans cross the solar system. By pairing compact reactors with efficient ...

NASA is leading an effort, working with the Department of Energy (DOE), to advance space nuclear technologies. The government team has selected three reactor design concept proposals for a nuclear ...

It has long become obvious that if we are to expand our reach into the solar system, the current means of propulsion for spaceships would simply not do. With such goals set for the near future, the ...

General Atomics and NASA have successfully tested a new type of nuclear thermal propulsion reactor fuel at the NASA Marshall Space Flight Center in Alabama. The new fuel could help power propulsion ...
