OpenPort™. The open standard for refueling in space.

One port to refuel, transfer, and dock. Androgynous, so any spacecraft can give fuel or receive it. Open licensed so the whole industry can use it. The hardware is free when you buy fuel from Spaceium.

  • ANDROGYNOUS

    Any two OpenPorts connect. Give or receive fuel.

  • OPEN-LICENSED

    Designed for anyone in the industry to integrate.

  • FLIGHT

    Get the hardware free when you buy fuel from Spaceium.

Any car can pull into any station because the fuel nozzle is standard. Space has no equivalent.

Without a standardized port, refueling stations can only serve the few spacecraft built to match them. Existing solutions are proprietary, limited in pressure, and not built for high pressure propellants.

So we built a completely different one, and we open licensed it to everyone

What makes OpenPort™ different

  1. Any spacecraft builder can integrate OpenPort™. Add it now and your spacecraft is ready to refuel in the future.

  2. No male or female side. Every OpenPort™ can both give and receive fuel, so any two spacecraft with OpenPort™ can connect.

  3. OpenPort™ transfers fuel and also docks two spacecraft together.

  4. Built for high pressure propellants like xenon and krypton, a first for the industry.

  5. Works with xenon, krypton, and water today. Being qualified for cryogenic fuels and hypergolics. The current version carries 2 propellant types, with up to 3 in future versions.

  6. High flow rates move fuel quickly, cutting time spent docked.

  7. A wide capture envelope lets two spacecraft connect even when they are not perfectly lined up.

Tested on Earth.
Going to orbit.

OpenPort™ has already transferred xenon in ground testing. Next, on Mission 2, we are sending OpenPort™ to the International Space Station to perform the first xenon transfer in orbit.

No one has done this before.

Highways changed what was possible on the ground. Refueling infrastructure will do the same in space.
