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. Nuclear ...

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 ...

UK space propulsion company Pulsar Fusion has conducted the first test of a prototype exhaust system for a nuclear fusion rocket engine that could dramatically cut transit times for missions to Mars ...

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 ...

Engineers from Ohio State University are developing a new way to power rocket engines, using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to ...

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 ...

Fundamentals of thermodynamics and aerodynamics -- Thermodynamic cycle analysis of gas turbines and air-breathing propulsion systems -- Aerodynamic design of axial flow compressors and turbines -- ...

UK-based Pulsar Fusion announced it has successfully achieved first plasma in its Sunbird nuclear fusion rocket exhaust system. The demonstration, a world’s ...

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 ...
