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

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

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

Russia's State Atomic Energy Corporation, Rosatom, recently developed a new spacecraft engine with impressive specifications.

A laboratory prototype of a plasma electric rocket engine based on a magnetic plasma accelerator has been produced by Rosatom ...

The military wanted to test the electromagnetic impacts of nuclear weapons in space. In 1962 they lit up the sky.

The reactor was a Kiwi, an obsolete experimental nuclear rocket engine built at Los Alamos ... They can be turned into small and relatively harmless particles by a signal commanding them to ...

The trials verify that the fuel can survive the harsh environment of a nuclear rocket reactor. Up until now, the main way of propelling spacecraft has been through chemical rockets. To be fair ...

Loosening up the design is key, because as Stark mentioned, previous ideas called for fitting the entire nuclear electric radiator system under a rocket fairing, or nose cone, which covers and ...
