Introducing OpenPort™: the first open licensed, androgynous refueling port for spacecraft. Flying to the International Space Station to perform the first xenon transfer in orbit.

Refuel in orbit. Do more.

A spacecraft launches with all the fuel it will ever have, and that tank sets the mission. Refueling changes that. Launch lighter and carry more payload. Go further and stay longer. Fly one vehicle on mission after mission.

The mission sets the limit, not the tank

The open standard refueling and docking interface

Any spacecraft can add it today and refuel in the future. OpenPort™ is open to everyone, so the industry can refuel through one interface.

Without the ability to refuel, spacecraft have a shelf life. OpenPort™ extends it.

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