UK space tech company, Pulsar Fusion, unveils fusion-powered rocket Sunbird aiming to revolutionize interplanetary travel by 2027.Sunbird differs by living in orbit, docking with other spacecraft and using nuclear fusion engine for rapid travel between planets.Sunbird's Duel Direct Fusion Drive (DDFD) harnesses fusion energy for high exhaust speeds, cutting Mars travel time in half.Fusion in space is facilitated by the vacuum environment, allowing for controlled bursts of energy without Earth's constraints.The engine uses deuterium and helium-3 mix to create propulsion, benefiting from charged protons over neutrons.Pulsar Fusion is testing Sunbird by simulating engine behavior with inert gases in vacuum chambers, with plans for in-orbit trials by 2027.Projected costs are around $90 million per spacecraft, with hopes to mine helium-3 from the Moon for future sustainable fuel sources.Sunbird is designed as a reusable space vehicle, featuring armor plating for durability and the capability to power systems of other craft.Pulsar Fusion envisions the UK as a leader in advanced space propulsion through its innovative projects like Sunbird.The global race to develop fusion rockets is underway, with Pulsar Fusion's Sunbird project aiming to transform future spaceflight.
