OrbitFab provides in-space refueling for satellites by deploying propellant depots and using reusable fuel shuttles to create an orbital gas-station network. In practice, propellant such as hydrazine is stored in orbit and delivered to customers’ satellites on demand, with revenue from selling propellant and contracts with operators including the U.S. Space Force starting in 2025. It differentiates itself by building an end-to-end orbital supply chain for propellant and logistics, rather than only servicing satellites, enabling a scalable, recurring fuel infrastructure. Its goal is to establish a practical, ongoing in-space propellant supply system that increases satellite utility and supports broader space industries like manufacturing and tourism.
