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 ...

This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the chemically propelled rockets the agency develops now is called nuclear ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
