NASA announced a mission to Mars using nuclear electric propulsion. How does it differ from earlier missions that utilized ...

The mission, called Space Reactor-1 Freedom (SR-1 Freedom), is set to launch in December 2028. This mission aims to showcase ...

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 fuel was subjected to full reactor heat and hydrogen gas and kept there for 20 minutes – about what a nuclear engine would have to endure during a boost maneuver. Other tests looked at how the ...

The breakthrough brings scientists a step closer to fusion propulsion - technology that mimics the energy reactions powering ...

NASA and the Defense Advanced Research Projects Agency (DARPA) announced Tuesday a collaboration to demonstrate a nuclear thermal rocket engine in space, an enabling capability for NASA crewed ...

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 ...

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 ...

BWX Technologies, Inc. (NYSE: BWXT) today announced that its reactor and fuel will be key components in the world’s first demonstration spacecraft using nuclear thermal propulsion. Working as part of ...

New details of the Trump administration’s plans for NASA, released Friday, revealed the White House’s desire to end the development of an experimental nuclear thermal rocket engine that could have ...

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 ...

NASA NIAC funded the Thin-Film Nuclear Engine Rocket (TFINER). By May 2025, it advanced to Phase II, focusing on maturing the technology, mission designs, small-scale thruster experiments, and isotope ...
