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

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

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 ...

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 ...

General Atomics Electromagnetic Systems (GA-EMS) just hit a massive milestone that could alter the future of space exploration. The company has successfully trialed a nuclear fuel that could one day ...

The first humans to Mars might someday ride a rocket propelled by a nuclear reactor to their destination. But before that can happen, nuclear thermal propulsion (NTP) technologies still have quite a ...

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 ...

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 ...

A new kind of space engine could change how we explore the solar system, and it's powered by the same force that lights up the stars. A British startup called Pulsar Fusion is working on a nuclear ...

Scientists have developed a new form of nuclear propulsion that they claim could slash mission times to Mars and enable voyages to the farthest reaches of the solar system. A team from Ohio State ...
