Nuclear propulsion would expel propellant from the engine's nozzle very quickly, generating high thrust. This high thrust allows the rocket to accelerate faster. These systems also have a high ...

After ten years of quiet research, Pulsar Fusion has unveiled a nuclear fusion-powered rocket called the Sunbird. This spacecraft isn’t just another science fiction concept—it’s being designed to fly ...

NASA and DARPA are developing a demonstration nuclear-powered rocket that could shorten travel time to Mars and make space ...

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

The key to the Sunbird rockets will be the Duel Direct Fusion Drive engines, which, according to Pulsar Fusion, will operate on energy from nuclear fusion. If the technology is successfully ...

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

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

U.K. start-up Pulsar Fusion has unveiled plans to build a fleet of reusable nuclear fusion-powered rockets, known as Sunbirds ...

Pulsar Fusion has introduced Sunbird, a nuclear fusion-powered rocket that could significantly cut space travel time.

Among the investors was André-Hubert Roussel, former CEO of ArianeGroup, who oversaw the development of Europe’s only ...

The machine learning simulations will guide the rocket engine’s design. In 2022, Pulsar secured funding from the UK Space Agency to develop a nuclear-fission based propulsion system ...

Nuclear rockets are the future of space propulsion ... which also develops plasma thrusters and is designed for more near-term fission engines as well, described the project to Live Science ...
