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

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

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

The USA's Defense Advanced Research Projects Agency has finalised an agreement with Lockheed Martin to begin work on the fabrication and design of an experimental nuclear thermal rocket and its engine ...

Angry Astronaut and Nextbigfuture commenter are making the case that SpaceX and Elon Musk must switch to nuclear thermal rockets to colonize Mars. I will review that the nuclear thermal rocket program ...

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 ...
