NASA’s push for a new nuclear rocket engine is not just another upgrade to the hardware we strap to the bottom of spacecraft.

A nuclear thermal propulsion engine could cut the travel time in half for future space explorers racing to the Red Planet.

Space agencies are moving closer to a new era of rocket propulsion that could fundamentally change deep-space travel. Nuclear ...

Nuclear thermal propulsion (NTP), a technology studied for decades but never tested in orbit, is now approaching a critical milestone. While no nuclear-powered rocket is expected to fly this year, ...

The Space Age framed nuclear propulsion as a quiet rethinking of movement, distance, and endurance beyond Earth.

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 ...
