Perhaps the opening is now for the greatest of all space adventures to be partaken by the two countries. The cause of space ...

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

The future of interplanetary travel is looking brighter, thanks to the new Sunbird nuclear-powered rocket designed by Pulsar ...

We are finally at the cusp for both nuclear electric propulsion and nuclear thermal propulsion,” said Kristin Houston, ...

British startup Pulsar Fusion has unveiled Sunbird, a space rocket concept designed to meet spacecraft in orbit, attach to them, and carry them to their destination at breakneck speed using nuclear ...

Theoretically, Sunbird's tremendous speeds could cut mission times to Mars in half, from seven to eight months to about four.

A British propulsion company is aiming to harness nuclear fusion and drastically cut travel times to far off places in space.

Pulsar Fusion says it wants the U.K. to be a leader in advanced space propulsion. With its past work on plasma thrusters and nuclear fission engines, and now its Sunbird project, the company is ...

A nuclear fusion rocket could be the key to unlocking speedy flights in space exploration, and one company hopes to test it as early as 2027.

Other companies are working on nuclear fusion engines for space propulsion, including Pasadena-based Helicity Space, which received investment from aerospace giant Lockheed Martin in 2024.

Nuclear rockets are the future of space propulsion, and while fission propulsion is rapidly developing, most believe fusion propulsion is still a ways off. However, a new U.K.-based company is ...
