NASA and its worldwide companions plan to deorbit the Worldwide Area Station on the finish of 2030, sending it to a fiery demise because it burns up in Earth’s ambiance. However that doesn’t imply humanity shall be giving up its sustained presence in low-Earth orbit.
The demise of the ISS will usher in a brand new period of business area stations. A number of corporations are already creating orbital analysis services and modular habitats that can permit astronauts to proceed residing and dealing in area. Many imagine their stations will supply elevated flexibility, affordability, and new alternatives for each scientific discovery and space-based trade.
Listed below are 5 key corporations stepping as much as fill the hole the ISS will depart behind.
1. Axiom Area
Axiom Area has obtained $140 million from NASA to develop Axiom Station by the company’s LEO Locations program. In February, the corporate raised an extra $350 million in non-public investor funds to speed up the supply of its ISS successor.
Development of Axiom Station is already underway, based on Axiom’s web site. The corporate’s companions at Thales Alenia Area—a world area producer—are within the technique of welding and machining the area station’s first module, and the primary items of fabricated flight {hardware} are coming collectively. Axiom plans to launch that module to the ISS in 2027.
Docking the module to the ISS will permit Axiom to check and validate its programs in orbit earlier than the module separates and rendezvous with the second module in orbit. After that, Axiom Station will be capable to function independently, however the firm will nonetheless want to connect three extra modules to completely construct out the station’s residing and analysis capabilities.
As soon as full, the first parts of Axiom Station shall be two habitat modules and a analysis and manufacturing module, however the firm intends so as to add others too. One deliberate addition is the SEE-1 module, which Axiom is manufacturing for the British firm Area Leisure Enterprise. SEE-1 will function an leisure venue—doubtlessly the primary one in area.
2. Huge Area
Axiom isn’t the one firm focusing on a 2027 launch for its area station. Huge Area is aiming to launch Haven-1 subsequent yr, too. Not like Axiom, nevertheless, Huge’s area stations are designed to function independently from day one.
The primary, Haven-1, shall be a standalone station able to supporting a crew of as much as 4 astronauts for short-duration analysis missions and industrial actions. It would primarily encompass crew quarters, a typical space, and a laboratory that can function a microgravity analysis and manufacturing facility. In mid-January, Huge introduced that Haven-1 had superior to the primary part of integration and is on observe to launch within the first quarter of 2027.
Haven-1 shall be a stepping stone to Haven-2, which is designed to succeed the ISS. Huge plans to launch the primary Haven-2 module in 2028, then add new modules each six months for a complete of 4 by 2030. At that measurement, the area station will be capable to assist crews of as much as eight astronauts. By 2032, Huge plans to develop the station to 9 modules able to supporting as much as 12 astronauts.
Huge missed out on the primary spherical of NASA’s LEO Locations program, nevertheless it does have present agreements with the company and is vying for a contract within the second spherical. Earlier this month, the corporate introduced that it has raised $500 million in non-public funding to speed up the manufacturing of its Haven area stations.
3. Blue Origin and Sierra Area
These two aerospace corporations have teamed as much as lead the event of Orbital Reef, which Blue describes as a “mixed-use enterprise park” 250 miles (400 kilometers) above Earth. The station shall be designed to offer analysis, industrial, worldwide, and industrial clients with area habitation, gear lodging, and even an onboard employees.
In its preliminary part of deployment, Orbital Reef will consist of 5 modules. The first modules would be the Core—a central hub with a few third of the liveable area of the ISS—a analysis module, and an expandable habitat module. Will probably be able to supporting as much as 10 crew members.
Orbital Reef has obtained $172 million from the LEO Locations program on high of company investments. In April 2025, NASA introduced that Orbital Reef accomplished a human-in-the-loop testing milestone, during which folks carried out day-in-the-life walkthroughs of life-sized mockups of main station parts. This may inform design suggestions for the station.
Blue and Sierra plan to launch the primary modules by 2027, although that appears optimistic given the truth that Orbital Reef remains to be within the design part. It’s additionally unclear precisely how lengthy it’ll take to scale the station to its closing capability.
4. Starlab Area LLC
Starlab Area LLC, a three way partnership between Voyager Area and Airbus, is creating Starlab Area Station as a part of the LEO Locations program. In mid-February, the corporate introduced that it had accomplished a essential NASA evaluate, clearing the way in which to proceed with fabrication, testing, and meeting of its station.
Like Haven-1, Starlab Area Station will launch as an operationally impartial system able to supporting as much as 4 astronauts. It would encompass a service module—offering propulsion, energy, and programs assist—and a habitat module that shall be launched to orbit on a single flight set to happen in 2029.
The station shall be outfitted with each a laboratory designed to assist a spread of experiments and expertise demonstrations in microgravity. The lab shall be divided into two foremost sections: the Inside Payload Laboratory (IPL) and the Exterior Payload Laboratory (EPL). The IPL will assist organic research, human research, supplies research, and extra, whereas the EPL will assist the testing and operation of payloads.
5. Max Area
This Florida-based startup is the newcomer on the scene. Max Area unveiled its plans to develop Thunderbird Station in December 2025, although it first shared plans for inflatable area station modules again in 2024. The corporate didn’t compete for a Section 1 award from the LEO Locations program however now hopes to win a NASA contract in Section 2.
Thunderbird is one other small, single launch station able to supporting as much as 4 astronauts at a time. The design relies on Max Area’s inflatable habitat expertise. As soon as in orbit, it’ll develop to a quantity of greater than 12,000 cubic ft (350 cubic meters)—the corporate claims will probably be essentially the most spacious area station ever constructed. The station shall be outfitted with payload lockers to assist authorities and industrial missions in addition to analysis gear.
Max Area is focusing on a 2029 launch, nevertheless it’s nonetheless too early to say whether or not the corporate is on observe to hit that focus on. The corporate goals to launch its first in-orbit expandable habitat demonstration within the first quarter of 2027.
Earlier this month, Max Area introduced a “multi-million-dollar” strategic funding from Voyager Applied sciences to “advance the event of next-generation expandable area habitats supporting sustained lunar operations and future deep-space missions,” nevertheless it’s unclear how a lot of that funding—if any—will go towards Thunderbird.
