Orbit Fab desires to construct “fuel stations” for satellites — which implies it wants the fuel cap, a mechanism for transferring propellant from an orbital tanker to the shopper spacecraft. That docking mechanism, known as RAFTI, is now flight-qualified and in the marketplace. The value tag for every port? Simply $30,000.
The Colorado-based startup (and former TechCrunch Disrupt Battlefield finalist) has been in operation since 2018, and its CEO and co-founder Daniel Faber has been working within the house business for many years; he’s probably finest recognized for heading up Deep Area Industries (DSI), an organization that was concentrating on asteroid mining. The corporate, which was based in 2012, was acquired by Bradford Area seven years later.
“If you need [to talk about] one thing that’s too early, that’s it,” he joked throughout a latest interview. As a part of the corporate’s efforts to finally construct tech able to prospecting a distant asteroid, DSI constructed satellite tv for pc thrusters for orbital maneuvering. This work, and subsequent conversations with prospects and colleagues, finally led Faber to imagine that the subsequent huge alternative was in-space refueling.
A part of it’s simple arithmetic: Colleagues and former prospects advised him that they might squeeze as a lot as $1 million in marginal income from satellite tv for pc missions from an additional kilogram of propellant.

“Spacecraft are optimized with the quantity of gasoline they’ve, and once they get to the tip of it, an additional kilo would give them 1,000,000 {dollars} of marginal income,” Faber stated. “We create a lot worth from that, we simply need to do it.”
The 2010s additionally noticed the emergence of a handful of satellite tv for pc servicing corporations, like Astroscale, that are creating know-how for house particles removing, satellite tv for pc life extension or last-mile satellite tv for pc supply. Faber calls these capabilities “tow truck functions,” and he realized that there would finally be a necessity for orbital fuel stations to enrich this fleet.
So Orbit Fab was born. Within the first 12 months of working, the corporate raised a $6 million seed spherical with contributions from Bolt and Munich Re Ventures, the VC arm of Munich Re Group, one of many largest underwriters of satellites and rockets. In 2023, the corporate raised a $28.5 million Sequence A spherical.
The startup’s know-how is bold, however the structure is pretty easy: The thought is to equip buyer satellites with the refueling port (Faber referred to it as a “fuel cap,” but it surely’s formally known as RAFTI) whereas the {hardware} continues to be on Earth. RAFTI, which stands for “Quickly Attachable Fluid Switch Interface,” can be used to gasoline spacecraft on the bottom previous to launch. As soon as a RAFTI-equipped satellite tv for pc runs out of propellant, one in every of Orbit Fab’s tankers would have the ability to choose up some gasoline from orbital depots and ship it straight to the shopper’s satellite tv for pc for refueling.
The one two issues the corporate sells are gasoline and the fueling ports; as one may count on, the true cash will come from the gasoline gross sales. On its web site, Orbit Fab says its hydrazine supply service in geostationary orbit will value $20 million for as much as 100 kilograms.
Given the simplicity of the structure, nailing every a part of the {hardware} is essential; therefore why it’s taken years for Orbit Fab to debut the refueling port. There are numerous variables to contemplate: the fee to the shopper, versus the potential marginal income from additional life on orbit; the affect of fueling on the shopper spacecraft; and the problem of creating a docking mechanism that may additionally switch propellant.
Along with all of those challenges, the corporate had to make sure its part complied with requirements from NASA, the Area Power and the American Institute of Aeronautics and Astronautics to make sure it’s secure, dependable and capable of face up to the tough atmosphere of house.
“This wasn’t low cost,” Faber stated. “It wasn’t fast, however on the finish of the day, now we have a chic design that meets these necessities and has a simplicity to it that comes from doing a design properly.”
One of many largest shifts from when he began the corporate to now, Faber stated, is the standing up of the U.S. Area Power and the consequences that’s had on the house business writ giant. Orbit Fab ended up pivoting a lot of its consideration to addressing the nascent wants of the Area Power, which was very eager about orbital mobility to keep away from house particles or rendezvous with different satellites.
The corporate anticipates the primary RAFTIs will go to orbit on prospects’ satellites later this 12 months. That will likely be adopted by the primary gasoline shuttle going up subsequent 12 months, as a part of a contract with the DOD to ship gasoline in geostationary orbit in 2025. Orbit Fab is aiming to promote 100 fueling ports this 12 months, which is able to put the RAFTI “on an honest share of satellites going to orbit,” Faber stated. Orbit Fab has a further settlement with an unnamed business buyer to ship “a major amount of gasoline” in a number of years, he added.
Past these milestones, Faber intimated that the corporate already has plans to improve RAFTI, and to design variants that would assist higher-pressure propellants. The crew can also be serious about redesigning the grapple housing for bigger spacecraft, ought to the market point out that’s the place they need to go subsequent.
“SpaceX has made rockets reusable, Orbit Fab makes satellites reusable,” Faber stated. “On this world at the moment, in case you’re operating a rocket firm, and also you’re not working in direction of reusable rockets, you’re working to a useless finish. The identical is true of satellites: Should you’re not making your satellites reusable, you’re simply placing preordained junk into orbit.”
