With a vision for a bustling in-space economy that can support permanent jobs in space, Orbit Fab is building the fundamental infrastructure this entire economy can be built upon: a fuel supply in orbit.

Today, satellites cannot be refueled. A single-use paradigm severely limits satellite mobility and holds back the development of economic activities in space. Orbit Fab is building the first Gas Stations in Space™ refueling infrastructure. We develop the supply chain architecture and technology to deliver propellant in space, allowing satellites to be built for lower cost, to be more flexible and maneuverable, to be more precisely controlled, and to operate longer, enabling operations and business models that have never before been imagined..

Established in 2018, we have already flown three tankers to space; with the first one flown within one year of founding. Working closely with partners and customers across the space industry, we are making the thriving in-space economy a reality.
