I’ve grown up with rockets that burn chemical fuel, but NASA’s next big leap in propulsion could make those engines look as dated as steam trains. By turning to nuclear power in space, the agency is ...

NASA has completed over 100 cold-flow tests of a full-scale nuclear rocket reactor prototype, demonstrating stable hydrogen ...

NASA engineers have completed first cold-flow tests of a full-scale nuclear thermal propulsion reactor, validating designs ...

That something is nuclear propulsion. Essentially, a nuclear rocket engine is a reactor that has hydrogen running through it as a propellant, which is heated to an astonishing 3,000 K (2,727 °C, 4,940 ...

Nuclear power has been proposed as a solution to meet the growing energy needs of artificial intelligence. But what if AI ...

NASA’s push for a new nuclear rocket engine is not just another upgrade to the hardware we strap to the bottom of spacecraft. It is an attempt to rewrite the basic rules of how far, how fast, and how ...
