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

NASA’s push for a new nuclear rocket engine is not just another upgrade to the hardware we strap to the bottom of spacecraft. It is an attempt to rewrite the basic rules of how far, how fast, and how ...

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 engineers have completed first cold-flow tests of a full-scale nuclear thermal propulsion reactor, validating designs ...

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 ...

The best, in fact, the only, candidate for this is the Nuclear Thermal Propulsion (NTP) system or nuclear rocket. First conceived of in 1945, this is a rocket that replaces burning chemical fuel with ...

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 ...

Forward-looking: Scientists have long envisioned nuclear electric propulsion as a transformative technology for unlocking the potential of solar system exploration. Now, two companies making steady ...
