British startup Pulsar Fusion has revealed an ambitious plan for a nuclear fusion-powered space rocket named Sunbird, backed by the UK Space Agency. The rocket is designed to leverage fusion propulsion to accelerate to speeds of up to 500,000 miles per hour, significantly surpassing existing spacecraft capabilities. Pulsar believes that space is a more suitable environment for fusion power due to its resemblance to the conditions where stars naturally undergo fusion. Unlike nuclear fission, fusion combines light elements like hydrogen to produce significantly more energy with minimal waste. The company plans to use helium-3 fuel for Sunbird, which generates protons for thrust, making it ideal for propulsion in space missions. Sunbird's first in-orbit fusion test is scheduled for 2027, with full functionality anticipated within the next few years. The concept involves deploying Sunbird as reusable docking stations in orbit for efficient interplanetary travel, with potential stations near Earth and Mars. Fusion rockets could revolutionize space travel by drastically reducing travel times to Mars, enabling missions to outer planets, asteroid mining expeditions, and more. While challenges remain in scaling fusion systems for space, experts believe fusion propulsion has the potential to revolutionize human space exploration beyond Mars, unlocking new resources like helium-3 on the Moon.
