Develops rapid, solar-thermal propelled satellite buses
Portal Space Systems designs and builds spacecraft for in-space mobility, focusing on a solar thermal propulsion-driven satellite bus called the Supernova. The bus uses solar energy to heat a propellant, delivering higher thrust and efficiency to perform large orbital changes, such as transferring from LEO to GEO or to cislunar space. The team includes veterans from SpaceX, Blue Origin, and Kuiper, helping mature the technology and manufacturing process. The company has secured over $3 million in Department of Defense funding, signaling a government and defense market focus, and plans to begin production of the Supernova by the end of 2026 from its Bothell, Washington base. Its goal is to move satellites more quickly and flexibly through space, enabling expanded space logistics and orbital transfer capabilities while winning government contracts.
