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 plans to send crewed missions to Mars over the next decade – but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip. This ...

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 ...

Phoebus 2A, the most powerful space nuclear reactor ever made, was fired up at Nevada Test Site on June 26, 1968. The test lasted 750 seconds and confirmed it could carry first humans to Mars. But ...

Mars has always felt like a distant neighbor, reachable only after a long, risky cruise through deep space. Now engineers inside NASA are sketching a very different future, one where a nuclear powered ...

Engineers from Ohio State University are developing a new way to power rocket engines, using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to ...

Humanity has lived in the space age for decades, but virtually every probe, rocket, and satellite shaping this era has relied on chemical propulsion. As scientists and engineers eye more distant ...

A new design for a nuclear-powered rocket could be the key to making the solar system more accessible. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

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 ...
