Orbit Fab

Orbit Fab is building the in-space refueling infrastructure to extend satellite operational life, advertising itself as "gas stations in space." The Colorado-based company develops fuel depots, refueling shuttles, and standardized fuel ports enabling satellites to receive propellant on orbit.

The Rapidly Attachable Fuel Transfer Interface (RAFTI) completed flight qualification in 2024 and is commercially available at $30,000 per unit. Orbit Fab shipped its first 12 RAFTI ports to customers, including eight for the Space Force and four for commercial customers including Astroscale. The interface allows satellites to receive propellant either in space or on the ground before launch.

In January 2024, Orbit Fab announced partnership with ClearSpace for in-space refueling services. The company will deliver fuel to Space Force satellites beginning in 2025, with U.S. government contracts totaling $21 million for refueling and orbital depot development. Orbit Fab was accepted to the Luxembourg Space Resources Accelerator in December 2024.

Orbit Fab offers hydrazine refueling services in GEO starting 2025, with 100 kg deliveries priced at $20 million. A commercial agreement with Astroscale will refuel the LEXI life extension servicer fleet with up to 1,000 kg of xenon propellant. The company's architecture includes fuel tankers serving as orbital depots and refueling shuttles delivering propellant to customer satellites. Orbit Fab continues building infrastructure for a sustainable in-space economy.
