Orbit Fab

Orbit Fab Inc. is a US in-space propellant supply company headquartered in Golden, Colorado, building a network of on-orbit propellant depots and standardising in-space refuelling interfaces through the RAFTI (Rapidly Attachable Fluid Transfer Interface) standard, enabling satellite operators to extend spacecraft mission life, reduce launch mass, and enable new orbital servicing operations. The company's propellant depots — with tankers planned for GEO and LEO orbits — provide hydrazine and xenon propellant delivery to customer spacecraft on orbit, and Orbit Fab is working with satellite manufacturers, propulsion suppliers, and government agencies to incorporate RAFTI into next-generation spacecraft as an industry standard refuelling port. Orbit Fab has partnered with and received investments from US government agencies, satellite manufacturers including Astroscale, and venture investors, targeting commercial satellite operators, government spacecraft designers, and constellation builders seeking to optimise satellite mass and lifetime through on-orbit propellant supply.
