Orbit Fab

Orbit Fab was founded by CEO Daniel Faber{{Cite web |title=Daniel Faber |url=https://www.theexecutive.io/danielfaber |access-date=2023-04-20 |website=The Executive |language=en}} and CDO Jeremy Schiel{{Cite web |title=Jeremy Schiel |url=https://www.bloomberg.com/profile/person/23065406 |access-date=2023-04-20 |website=Bloomberg}} in 2018 to extend the lifetime of satellites.{{Cite web |title=About Us — Orbit Fab {{!}} Spacecraft Refueling |url=https://www.orbitfab.com/about/ |access-date=2023-05-18 |website=Orbit Fab |language=en}}

In 2019, the company completed testing of a fuel-transfer system aboard the International Space Station, demonstrating the ability to transfer fuel between spacecraft in microgravity. In the experiment, water was first transferred between two small satellites, and later the water was inserted into the water supply of the space station, making Orbit Fab the first private company to supply water to the ISS with its own proprietary equipment and processes.{{Cite web |last=Foust |first=Jeff |date=June 19, 2019 |title=Orbit Fab Demonstrates Satellite Refueling Technology on Space Station |url=https://www.space.com/orbit-fab-demonstrates-satellite-refueling-technology-on-iss.html |access-date=2023-04-20 |website=Space.com |language=en}}

On June 24, 2021, Orbit Fab launched Tanker-001, a test device for its depot satellites. Tanker-001 weighs {{Convert|35|kg|lb|abbr=on}} and was used to test the refueling system.{{Cite journal |last1=Bultitude |first1=James |last2=Burkhardt |first2=Zach |last3=Harris |first3=Maya |last4=Jelderda |first4=Mark |last5=Suresh |first5=Srinivasan |last6=Fettes |first6=Logan |last7=Faber |first7=Daniel |last8=Schiel |first8=Jeremy |last9=Cho |first9=James |last10=Levitt |first10=David |last11=Kees |first11=Devin |last12=Gallucci |first12=Sergio |date=2021-08-07 |title=Development and Launch of the World's First Orbital Propellant Tanker |url=https://digitalcommons.usu.edu/smallsat/2021/all2021/121 |journal=Small Satellite Conference}}

The company plans to launch its refueling service to geostationary orbit in 2025. On May 26, 2023, the company announced that it had selected an Impulse Space Mira spacecraft as a fuel depot to perform an on-orbit refueling demonstration test for the U.S. military in 2025. The demonstration will attempt to refuel the USSF Tetra-5 spacecraft with approximately {{Convert|50|kg|lb}} of hydrazine propellant using Orbit Fab's RAFTI refueling port.{{Cite web |last=Erwin |first=Sandra |date=2023-05-25 |title=Orbit Fab selects Impulse Space's orbital vehicle for in-space refueling demo |url=https://spacenews.com/orbit-fab-selects-impulse-spaces-orbital-vehicle-for-in-space-refueling-demo/ |access-date=2023-05-26 |website=SpaceNews |language=en-US}}

Orbit Fab is developing in-space refueling systems to increase the lifespans of satellites that are in need of additional fuel. The company currently has a contract to refuel satellite-servicing satellites for Astroscale in geostationary orbit with {{Convert|1000|kg|lb}} of xenon fuel{{Cite web |last=Erwin |first=Sandra |date=January 11, 2022 |title=Orbit Fab secures deal to refuel Astroscale's satellite-servicing robots |url=https://spacenews.com/orbit-fab-secures-deal-to-refuel-astroscales-in-space-servicing-robots/ |access-date=2023-04-17 |website=SpaceNews |language=en-US}} in addition to a total of US$21 million in defense contracts, including a SpaceWERX contract for a proximity and rendezvous demonstration, a US$13.3 million contract with the United States Department of Defense for in-space refueling of geostationary United States Space Force satellites,{{Cite news |date=2022-10-11 |title=Colorado Startup Wins $13.3 Million US Contract for Satellite Refueling |language=en |work=Bloomberg.com |url=https://www.bloomberg.com/news/articles/2022-10-11/colorado-startup-building-gas-stations-in-space-gets-13-3-million-us-contract |access-date=2023-05-19}} and a STRATFI mission for the development of docking ports.{{Cite web |last=Zisk |first=Rachael |date=2023-04-18 |title=Orbit Fab Closes $28.5M Series A |url=https://payloadspace.com/orbit-fab-closes-28-5m-series-a/ |access-date=2023-05-19 |website=Payload |language=en-US}}

The company is working to provide fuel-replenishment through a docking system using their self-developed port system called RAFTI, eliminating the need for robotic arms to grapple spacecraft. The company is planning to send depot spacecraft into different orbits, and satellites will either refuel themselves at the depot or to use "fuel shuttle" spacecraft provided by Orbit Fab. Fuel will be provided starting in 2025 in geostationary orbit for US$20 million per {{Convert|100|kg|lb}} hydrazine,{{Cite web |last=Foust |first=Jeff |date=2022-08-30 |title=Orbit Fab announces in-space hydrazine refueling service |url=https://spacenews.com/orbit-fab-announces-in-space-hydrazine-refueling-service/ |access-date=2023-05-18 |website=SpaceNews |language=en-US}} although the company has also announced plans to provide other fuels, including xenon, water, and nitrogen, and expand its services to other orbits in the future.{{Cite web |title=Orbit Fab |url=https://aerospacebiz.jaxa.jp/en/spacecompany/orbitfab/ |access-date=2023-05-18 |website=JAXA Business Development and Industrial Relations Department |language=en-US}}

The company also announced plans to partner with Astroscale and Northrop Grumman to refuel satellites that do not yet have RAFTI ports.

The Rapidly Attachable Fluid Transfer Interface (RAFTI) was developed by Orbit Fab as a standard refueling port for spacecraft. The RAFTI has a size of 45 x 75 x 75 mm, a weight of {{Convert|500|g|oz}}, and operates under either {{Convert|650|psi|abbr=on}} or {{Convert|3000|psi|abbr=on}}.{{Cite web |title=RAFTI - Rapid Attachable Fluid Transfer Interface |url=https://catalog.orbitaltransports.com/rafti/ |access-date=2023-05-18 |website=Orbital Transports |language=en}}

Orbit Fab developed a mission analysis software called UMPIRE (Universal Mission Planner for Investigating Refueling Effectiveness) that allows users to plan their mission and spacecraft using the refueling systems provided by Orbit Fab.{{Cite web |title=UMPIRE — Orbit Fab {{!}} Spacecraft Refueling |url=https://www.orbitfab.com/umpire/ |access-date=2023-05-19 |website=Orbit Fab |language=en}}
