The UK-based disruptor in clean space propulsion has unveiled its groundbreaking creation: the Sunbird, a nuclear fusion rocket poised to reach a mind-blowing speed of 500,000 kilometers per hour (329,000 mph). Unlike traditional chemical rockets, which burn fuel at relatively puny speeds by space standards, the Sunbird employs nuclear fusion, the same process that powers the Sun itself. As Pulsar Fusion races toward space trials, one thing is certain: the Sunbird is not just a rocket.
