About Axiom Space
Axiom Space builds and operates commercial human spaceflight services and orbital infrastructure, including Axiom Station, a planned commercial successor to the ISS. The company sells private astronaut missions plus in‑space research and manufacturing opportunities, and it develops NASA’s next‑generation lunar EVA spacesuit under the xEVAS contract. Founded in 2016 and headquartered in Houston, it is privately held and will first attach station modules to the ISS before operating a standalone platform.
