Signal UK Startup Ignites Plasma Inside Nuclear Fusion Rocket — World First

Summary

The UK startup Pulsar Fusion, headquartered in Bletchley, ignited plasma inside a nuclear fusion rocket engine for the first time, announcing the result on 26 March 2026 at Amazon's MARS Conference in California. The system, called the "Sunbird fusion exhaust system," creates plasma using electric and magnetic fields. CEO Richard Dinan called it an "exceptional moment" for the company. The technology could in principle deliver up to 1,000 times more thrust than conventional rocket engines, with potential spacecraft speeds of about 800,000 km/h, which could cut a Mars mission from months to weeks. Pulsar Fusion plans further testing with upgraded superconducting magnets for better plasma containment. The announcement noted the space economy is projected to exceed $1.8 trillion by 2035.
