Construction has continued on Houston-based Axiom Space’s project to construct the world’s first commercial space station.

Thales Alenia Space, a European aerospace manufacturer, will develop the two pressurized modules of the Axiom Space Station. The two elements, which are scheduled to launch in 2024 and 2025, will dock to the International Space Station before eventually detaching and operating as a fully independent, commercial station.

Axiom will also operate the first fully private mission to the ISS, scheduled for January 2022. Axiom Mission 1 will send four private astronauts to space onboard a SpaceX Crew Dragon, for an eight-day mission.
