NASA and General Atomics tested the fuel by exposing it to temperatures up to 3,000 Kelvin (4,940 Fahrenheit or 2,727 Celsius ...

While this latest test doesn’t make nuclear-powered rocket engines viable just yet, it’s an important step on the journey.

Rosatom scientists have developed a laboratory prototype for a plasma electro-reactive rocket engine based on a magnetic ...

The fuel was subjected to full reactor heat and hydrogen gas and kept there for 20 minutes – about what a nuclear engine would have to endure during a boost maneuver. Other tests looked at how ...

NASA and its partners have successfully tested a nuclear thermal propulsion (NTP) fuel that could revolutionize deep-space ...

Inspectors say Iran is dangerously close to making a nuclear weapon. If it goes that route, the B-2 bomber has the stealth and payload needed to knock out buried nuclear sites.

During the tests, the fuel was subjected to the maximum heat of a reactor for 20 minutes. That's 4,220 degree Fahrenheit (2,326°C), roughly equivalent to the heat a nuclear rocket engine would ...

Russian scientists claim to have developed a plasma electric rocket engine that could enable travel to Mars in just one to ...

A new type of nuclear thermal propulsion reactor fuel has been successfully tested ... more efficient than conventional chemical rocket engines," Back continued. "We are excited to continue ...

flow-through nuclear reactor. The fission reaction is harnessed to generate heat to energize a helium gas propellant, which is exhausted to produce thrust. A follow-on operational engine would replace ...
