The company released preliminary plans in February 2020 for how the Axiom Orbital Segment could form the basis for the Axiom Station, constructed out of the Axiom Segment and additional elements upon ISS retirement and separation, including a power and thermal module with an

. The company planned to launch its first four modules in consecutive years starting from the mid-2020s.
The interior concept of the crew quarters of Axiom Orbital Segment was conceived in 2018 by French architect and designer
Philippe Starck. Renderings of the habitat show a chamber with walls that are covered with tufted padding and studded with hundreds of color-changing LEDs. The Axiom Orbital Segment is intended to have amenities including high-speed Wi-Fi, video screens, picture windows and a glass-walled cupola – which Axiom calls "the largest window observatory ever constructed for the space environment".
In December 2024, Axiom Space announced a change in their station assembly plans. Instead of assembling the Axiom Orbital Segment at the ISS, the station was now planned to fly independently after the launch of the Habitat One (Hab-1) module. The Payload Power Thermal Module would be launched first and dock with the ISS while awaiting the launch of Hab-1, after which it would detach from the ISS and form the Axiom Station upon connecting with Hab-1.
Planned modules
Each Axiom Station module is an independent spacecraft equipped with all the systems needed to maneuver in orbit – including propulsion.
PPTM
Axiom's first module, the Payload Power Thermal Module (PPTM), is scheduled to be launched to the ISS no earlier than 2027.
PPTM is expected to provide power and thermal capacity equivalent to that of the ISS via solar array.
The module will initially be attached to one of two ports currently used by cargo spacecraft before detaching from the ISS to dock with Hab-1 in 2028.
Hab-1
Axiom's second module, Habitat One (Hab-1), is expected to be launched no earlier than 2028.
It will provide quarters for four crew members and volume to accommodate research and manufacturing applications. Each personal crew quarter is equipped with a large Earth-viewing window and touch-screen communications panel. A docking adapter allows visiting vehicles to dock to the Axiom Station; four radial ports on Hab-1 provide for the addition of future modules and increase the station's docking capability.
It will have propulsion, guidance, navigation and station control systems. The first windowed pressurized module is approximately 11 meters long and 4.2 meters in diameter at the widest part.

reported significant progress on the fabrication of the module in early 2024.
When Hab-1 is launched into orbit, PPTM will undock from the ISS and dock with Hab-1, forming the initial two-module free-flying Axiom Station.
AL
Axiom's third module, the Airlock Module (AL), is expected to be launched in the late 2020s.
The addition of an airlock module will enable
extravehicular activities, making Axiom Station a fully capable space station.
Hab-2
Axiom's fourth module, Habitat Two (Hab-2), is expected to be launched after the Airlock Module.
It will provide quarters for an additional four crew members allowing the station to support up to eight crew.
It provides complete
ECLSS support, commercial high data satellite communications and a

for the Axiom Station.
RMF

Axiom's fifth module, the Research and Manufacturing Facility Module with Earth Observatory (RMF), is expected to be launched in the early 2030s.
It will provide access to the unique microgravity environment as a platform to enable research, product development, process improvement, and space manufacturing.
The Earth Observatory is a glass-walled cupola attached to the RMF.
SEE-1
Axiom Space plans to manufacture the SEE-1 module for the British company ''Space Entertainment Enterprise'' (or S.E.E.). It is planned to be a six meter spherical
inflatable module and to fulfill the purpose of a first entertainment studio in space. SEE-1 is expected to launch sometime after Hab-1.

The primary structure for Hab-1 is expected to be delivered from Italy to Houston, Texas in early 2023 where Axiom Space will complete assembly and integration of all systems before launch.

. The first module, PPTM, is planned to attach to one of two ISS ports currently used by cargo spacecraft. PPTM will separate from the ISS and berth to Hab-1 once that module is launched. The Airlock Module, Hab-2 and RMF will then follow in that order.
As Axiom Station is a
modular space station, the modules may be moved to different ports as needed.
Axiom is, under agreements between the US and India, looking into diversifying its launch providers and possibly using Indian or European launch systems.
