Elon Musk and Donald Trump aim to reach Mars and want to do so in the next few years. Well, the British aerospace company ...

The company’s ambitious new Sunbird design aims to harness nuclear fusion in space, despite the fact that commercializing ...

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.

Temperatures can hit absolute zero, and there’s no air to mess with the reaction. Fusion in orbit doesn’t need to run constantly either. Pulsar’s rocket engine burns for short bursts—just enough to ...

British startup Pulsar Fusion has come up with a wild new concept for a nuclear fusion-powered space rocket that, it claims, ...

Unlike conventional chemical rockets, Sunbird relies on nuclear fusion – a process that replicates the energy production at the core of stars – to propel spacecraft.

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.
