Orbit Fab

(English) Gas Stations in Space™


Orbit Fab operates gas stations in space. It is a venture-backed startup founded in 2018 that has successfully tested its technology on the ISS. It envisions a thriving in-space market for products and services that support both existing space businesses like communications and Earth observation and new industries such as space tourism, manufacturing, and mining. The first step is achieving ubiquitous availability of satellite propellant in Earth Orbit, expanding the operational potential of new and existing space assets and providing unprecedented business model flexibility for satellite owners. In the future, valuable satellites will no longer be thrown away when they run out of fuel. Orbit Fab’s goal is to build the infrastructure that provides fuel and other materials to customers when and where they need it, to enable business models never before thought possible.


Orbit Fab’s business is selling spacecraft propellant in orbit. The company enables this by providing the refueling technology that customers need to refuel their assets on-orbit. The company also builds and deploys the tankers that supply the propellant, and manages the orbital logistics to ensure satellite servicing and client spacecraft can refuel as needed. Orbit Fab is a member of the CONFERS satellite servicing association.
