Orbit Fab, founded in 2018, is a pioneering American startup and in-space refueling company dedicated to developing and deploying propellant and material supply chain infrastructure in space, including "Gas Stations in Space™". Orbit Fab aims to extend the lifespan and operational capabilities of satellites by providing on-orbit refueling services, utilizing its Rapidly Attachable Fluid Transfer Interface (RAFTI) and fuel depot satellites. Key partners and customers include the U.S. Space Force, Astroscale, and the UK Space Agency; they offer Hydrazine, High Test Peroxide, Green Monopropellants, Water, and Nitrogen. Associated keywords: satellite refueling, in-space services, propellant supply, space logistics, RAFTI, fuel depots.
