General Atomic's new nuclear fuel was subjected to the maximum heat of a reactor for 20 minutes in the latest tests.

NASA has achieved a critical milestone in space exploration with the successful testing of advanced nuclear thermal ...

General Atomics Electromagnetic Systems (GA-EMS) has successfully tested the nuclear fuel that may one day propel and power the spacecraft of the future. The trials verify that the fuel can survive ...

A new type of nuclear thermal propulsion reactor fuel has been successfully tested at NASA’s Marshall Space Flight Center, ...

An alternative technology to the chemically propelled rockets the agency develops now is called nuclear thermal propulsion, which uses nuclear fission and could one day power a rocket that makes ...

NASA said nuclear thermal rockets can be three or more times more efficient than conventional chemical propulsion and would reduce transit time, essential for an eventual mission to Mars.

General Atomics, for instance, is looking into how nuclear fuel can survive "after thermal cycling in hydrogen ... three times more effectiveness that rocket engines power by chemical propellants.

There are several mega-rockets already being developed that ... to develop and demonstrate advanced nuclear thermal propulsion technology as soon as 2027," said Nasa boss Bill Nelson.

Rather than cram the whole system into an existing rocket, this would allow ... and human exploration using nuclear electric propulsion and nuclear thermal propulsion.

Scientists have thought about attaching nuclear, thermal-rocket engines to ammonia-heavy asteroids and redirecting the asteroids so that they crash into Mars and release the meteor's ammonia and ...

KUSHIMOTO, Wakayama Prefecture--A site originally envisaged for a nuclear power plant is now on course to become the nation’s first private-sector launch pad for small rockets. The launch pad ...
