Orbit Fab desires to construct “gasoline stations” for satellites — which suggests it wants the gasoline 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 worth 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 area business for many years; he’s probably greatest recognized for heading up Deep House Industries (DSI), an organization that was concentrating on asteroid mining. The corporate, which was based in 2012, was acquired by Bradford House seven years later.
“In order for you [to talk about] one thing that’s too early, that’s it,” he joked throughout a current interview. As a part of the corporate’s efforts to ultimately construct tech able to prospecting a distant asteroid, DSI constructed satellite tv for pc thrusters for orbital maneuvering. This work, and subsequent conversations with clients and colleagues, ultimately led Faber to imagine that the subsequent massive alternative was in-space refueling.
A part of it’s simple arithmetic: Colleagues and former clients instructed him that they may 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 gas they’ve, and once they get to the tip of it, an additional kilo would give them one million {dollars} of marginal income,” Faber stated. “We create a lot worth from that, we simply must do it.”
The 2010s additionally noticed the emergence of a handful of satellite tv for pc servicing firms, like Astroscale, that are growing expertise for area particles elimination, satellite tv for pc life extension or last-mile satellite tv for pc supply. Faber calls these capabilities “tow truck purposes,” and he realized that there would ultimately be a necessity for orbital gasoline stations to enhance this fleet.
So Orbit Fab was born. Within the first yr 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 Collection A spherical.
The startup’s expertise is formidable, however the structure is pretty easy: The thought is to equip buyer satellites with the refueling port (Faber referred to it as a “gasoline cap,” but it surely’s formally known as RAFTI) whereas the {hardware} remains to be on Earth. RAFTI, which stands for “Quickly Attachable Fluid Switch Interface,” can be used to gas spacecraft on the bottom previous to launch. As soon as a RAFTI-equipped satellite tv for pc runs out of propellant, considered one of Orbit Fab’s tankers would be capable of choose up some gas 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 gas and the fueling ports; as one may count on, the true cash will come from the gas gross sales. On its web site, Orbit Fab says its hydrazine supply service in geostationary orbit will price $20 million for as much as 100 kilograms.
Given the simplicity of the structure, nailing every a part of the {hardware} is crucial; therefore why it’s taken years for Orbit Fab to debut the refueling port. There are lots of variables to contemplate: the fee to the shopper, versus the potential marginal income from further life on orbit; the impression of fueling on the shopper spacecraft; and the problem of growing 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 House Power and the American Institute of Aeronautics and Astronautics to make sure it’s secure, dependable and capable of face up to the cruel setting of area.
“This wasn’t low cost,” Faber stated. “It wasn’t fast, however on the finish of the day, we’ve a sublime design that meets these necessities and has a simplicity to it that comes from doing a design effectively.”
One of many largest shifts from when he began the corporate to now, Faber stated, is the standing up of the U.S. House Power and the consequences that’s had on the area business writ massive. Orbit Fab ended up pivoting a lot of its consideration to addressing the nascent wants of the House Power, which was very curious about orbital mobility to keep away from area particles or rendezvous with different satellites.
The corporate anticipates the primary RAFTIs will go to orbit on clients’ satellites later this yr. That can be adopted by the primary gas shuttle going up subsequent yr, as a part of a contract with the DOD to ship gas in geostationary orbit in 2025. Orbit Fab is aiming to promote 100 fueling ports this yr, which is able to put the RAFTI “on a good share of satellites going to orbit,” Faber stated. Orbit Fab has an extra settlement with an unnamed industrial buyer to ship “a big amount of gas” in just a few years, he added.
Past these milestones, Faber intimated that the corporate already has plans to improve RAFTI, and to design variants that might help higher-pressure propellants. The staff 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 present, in the event you’re working a rocket firm, and also you’re not working in the direction of reusable rockets, you’re working to a lifeless finish. The identical is true of satellites: If you happen to’re not making your satellites reusable, you’re simply placing preordained junk into orbit.”
