A nuclear thermal rocket engine in development could one day transport humans to Mars. The Defense Advanced Research Projects Agency, a research arm of the US Department of Defense, and NASA are ...

NASA and DARPA plan to launch a nuclear-powered spacecraft to Earth orbit in the next few years, to test propulsion technology that could get humanity to Mars.

NASA and DARP will collaborate on a project to develop nuclear thermal rockets that will shorten transit times to Mars, increase load capacity and generate more power.

Angry Astronaut describes a hypothetical nuclear thermal rocket assembled in orbit. He assumes a nuclear thermal rocket will be working by the end of 2030. He says the SpaceX approach to building a ...

One of these designs, known as a Centrifugal Nuclear Thermal Rocket (CNTR), uses a centrifuge to turn uranium fuel into a molten liquid that heats hydrogen and produces thrust.

NASA and DARPA announced a collaboration to demonstrate a working nuclear thermal rocket by 2027 with the goal of sending humans to Mars as quickly as possible.
