Fusion has long been the propulsion end-goal for interplanetary travel, and a U.K.-based company thinks on its way to ...

If we achieve advanced nuclear, antimatter propulsion or other advance propulsion it would be possible to achieve near ...

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 ...

Unlike conventional chemical rockets, nuclear thermal propulsion (NTP) systems use a reactor to heat liquid propellant, such as hydrogen, to extreme temperatures. The heated propellant is then ...

Advanced propulsion technologies, such as ion engines and nuclear thermal rockets, are also being explored for future space exploration missions.

On Episode 152 of This Week In Space, Rod Pyle and Tariq Malik host Dr. Robert O'Brien, Director of the Universities Space ...

AI gives a thumbs up to Brett Bellmore innovative modifications to Robert Zubrin’s Nuclear Salt Water Rocket (NSWR).

The Sunbird nuclear fusion rocket concept has the potential to more than halve the time to travel to Mars and cut travel time ...

As the heated propellant expands, it’s ultimately exhausted out of a nozzle in much the same way as in a traditional rocket. It’s also similar to the concept of nuclear thermal propulsion ...

NASA and DARPA announced in 2023 that they were working on a nuclear thermal rocket engine, with a planned launch demonstration as early as 2027. The big drive behind these new propulsion ...

The Sunbird concept is for the fusion-powered ‘tugs’ to be permanently based in space, able to dock with spacecraft and ...

and future potential of nuclear electric and nuclear thermal propulsion systems, which could revolutionize our ability to explore Mars and beyond — both robotically and with human crews.
