UK Startup Unveils Sunbird: World’s Fastest Fusion Rocket to Slash Mars Travel Time
April 15, 2025
Pulsar Fusion, a U.K.-based aerospace startup founded by Richard Dinan, has unveiled a concept design video showcasing its ambitious Sunbird nuclear fusion rocket.
This revolutionary vehicle could significantly reduce travel time to Mars, cutting it from the typical seven to eight months down to approximately four months.
Pulsar Fusion has secured funding from the U.K. Space Agency and is set to begin in-orbit testing of the Sunbird's Dual Direct Fusion Drive in late 2025.
The ultimate goal is to achieve successful nuclear fusion in space by 2027, despite the challenges of harnessing nuclear fusion as a large-scale energy source on Earth.
Designed to operate independently of gravitational assistance, the Sunbird will function as an interplanetary tug, capable of boosting other spacecraft.
The Sunbird aims to achieve unprecedented speeds of 329,000 mph (500,000 kph), positioning it as the fastest self-propelled object ever conceived.
