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

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 ...

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 ...

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 ...

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 ...

Jim Bickford is leading the Thin Film Isotope Nuclear Engine Rocket (TFINER) project to develop a system for propelling a craft through space faster and farther than ever before. This technology has ...

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 ...

Viewed from orbit, Jackass Flats — situated in southern Nevada about 65 miles northwest of Las Vegas — could easily be confused for Mars. The alluvial basin is full of tan and gray regolith, hued ...
