The team successfully created plasma using electric and magnetic fields inside its experimental and early prototype 'Sunbird fusion exhaust system'. The test took place at the company's headquarters in Bletchley, UK, and was streamed to California. Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
At those speeds, missions to Mars could shrink from months-long journeys to just a few weeks. Shorter trips would not only make missions cheaper and more practical but could also reduce major health risks astronauts face in space, including radiation exposure and long periods spent in microgravity. The company now plans further testing of its Sunbird system to improve performance, with upcoming upgrades including more powerful superconducting magnets designed to better contain and control plasma.
With the space economy projected to exceed $1.8 trillion by 2035, faster in-space transport isn't just a scientific goal; it's an economic one.
