Space station concept art and design in 2026: Axiom, Orbital Reef, Starlab, and Vast
The International Space Station is scheduled for deorbit in 2030 or 2031. Its replacement will not be a single government-owned outpost — it will be a collection of commercial space stations built and operated by private companies, with NASA as a tenant rather than an owner. Four companies are developing orbital habitats right now, and the concept art and design renderings they have released reveal distinctly different philosophies about what a space station should look like, how it should function, and who it should serve.
This is a guide to the stations being designed in 2026 — what the concept art shows, what the engineering behind those renderings actually involves, and what it means for space industry careers.
Axiom Station
Developer: Axiom Space (Houston, TX) NASA CLD Award: $130 million (2020) Target: First module (Axiom Habitat 1) attached to ISS by 2026-2027, eventual free-flying station by ~2030
Axiom Space's design stands apart because it is the only commercial station program building hardware that will initially attach to the existing ISS. The plan is incremental: Axiom modules dock to the ISS Node 2 forward port, operate as part of the ISS for several years, then detach and become an independent free-flying station before the ISS is deorbited.
What the concept art shows: Axiom's renderings depict a multi-module station with a distinctive central hub node and radiating pressurized modules. The interior design work, led by Philippe Starck (the French industrial designer behind hundreds of consumer products), emphasizes large observation windows, padded walls with warm earth tones, and LED panels that simulate natural light cycles. The concept art looks less like a spacecraft and more like a boutique hotel — intentionally. Axiom is targeting commercial customers, sovereign astronaut programs, and space tourism alongside NASA research.
Engineering reality behind the art: The Axiom modules are based on conventional aluminum pressure vessel construction — similar to ISS module architecture but with modern avionics and power systems. The Starck-designed interior is a real engineering challenge: soft goods (padding, fabric panels) in microgravity must meet strict flammability standards (NASA-STD-6001), off-gassing requirements, and must be maintainable by crew without specialized tools. The large windows shown in concept art require optical-quality fused silica panes that can withstand thermal cycling and micrometeorite impacts.
Axiom Space has been hiring structural engineers, thermal analysts, ECLSS (Environmental Control and Life Support Systems) engineers, and interior design specialists who can bridge the gap between aesthetics and spacecraft certification. The company is based in Houston near Johnson Space Center, with 200+ employees and growing. Browse Axiom Space jobs on Zero G Talent.
Orbital Reef (Blue Origin + Sierra Space)
Developers: Blue Origin (lead), Sierra Space, Boeing, Genesis Engineering NASA CLD Award: $130 million (2021) Target: Initial operational capability by late 2020s
Orbital Reef is the joint venture between Blue Origin and Sierra Space to build what they describe as a mixed-use business park in low Earth orbit. The concept art positions it as the most architecturally ambitious of the four stations.
What the concept art shows: Renderings depict a large, sprawling complex with multiple modules of different shapes and sizes connected by nodes. The most visually striking element is Sierra Space's LIFE (Large Integrated Flexible Environment) module — an inflatable habitat that expands to three stories of pressurized volume once deployed. In concept art, the LIFE module dwarfs conventional rigid modules, providing cavernous interior spaces shown with researchers, manufacturing equipment, and even media production facilities.
Blue Origin's node and utility modules use a more conventional cylindrical design, while the station's overall layout resembles a branching tree structure rather than the ISS's linear truss arrangement. Windows are prominent — large cupola-style observation ports appear in multiple renderings.
Engineering behind the art: The LIFE module is a real technical breakthrough if it works at scale. It uses Vectran fabric (the same material used in Mars airbag landing systems) that becomes stronger than steel when pressurized. Sierra Space has burst-tested LIFE modules to 77 psi against a 60.8 psi NASA recommendation, and conducted a full-scale burst test that demonstrated the structural margins. The challenge is not strength — it is meteorite protection, thermal insulation integration, and creating a rigid internal outfitting structure within a flexible shell.
Blue Origin's contribution focuses on the station's core systems: power, propulsion, thermal management, and the orbital maneuvering system. Their concept art shows solar arrays significantly larger than current ISS panels, reflecting the power demands of commercial research and manufacturing payloads.
| Station Element | Provider | Key Technology |
|---|---|---|
| Core module and nodes | Blue Origin | Aluminum pressure vessels, propulsion |
| LIFE habitat | Sierra Space | Vectran inflatable modules |
| Science module | Boeing | ISS heritage research racks |
| Single Person Spacecraft | Genesis Engineering | Free-flying EVA alternative |
Starlab (Voyager Space + Airbus)
Developers: Voyager Space (lead), Airbus Defence and Space, Mitsubishi, MDA Space NASA CLD Award: $160 million (2021) Target: Launch on a single Starship flight, late 2020s
Starlab takes the opposite approach from Orbital Reef's modular complexity. Its concept art depicts a single, large module launched in one piece — no on-orbit assembly required. The design philosophy is simplicity and speed to market.
What the concept art shows: A single large pressurized module roughly the size of the ISS Destiny laboratory, launched fully outfitted on a SpaceX Starship. The renderings show a George Washington Bridge-style open interior — one large continuous volume rather than multiple connected modules. External solar arrays and a robotic arm (supplied by MDA, who built the Canadarm) complete the exterior. The interior concept art shows standardized research racks along the walls, a crew quarters section, and a large observation window.
The Starlab concept art is notable for what it does not show: no sprawling multi-module complex, no inflatable habitats, no dramatic architectural statement. It looks like a functional laboratory, because that is what it is designed to be.
Engineering behind the art: Launching a fully outfitted station module on Starship eliminates the need for on-orbit assembly — the single biggest risk and schedule driver in space station construction. The ISS required over 40 assembly flights. Starlab requires one. The trade-off is volume: a single Starship payload cannot match the total volume of a multi-module station.
Airbus brings ISS Columbus module heritage. Mitsubishi brings experience from the Japanese Kibo module. MDA provides the robotic arm. This is an international consortium leveraging existing expertise rather than developing new structural technologies.
Space station concept art is marketing material — it shows the vision, not necessarily the final product. The ISS concept art from the 1980s (then called Space Station Freedom) depicted a far more elegant structure than what was actually built. Expect every commercial station to look different from its renderings by the time hardware flies. The engineering constraints of launch vehicle payload fairings, thermal management, and micrometeorite protection always override aesthetic ambitions.
Vast Haven-1 and Haven-2
Developer: Vast (Long Beach, CA) NASA CLD Award: None (fully privately funded) Target: Haven-1 launch on Falcon 9 in 2026, Haven-2 on Starship by ~2028-2029
Vast is the wild card. Founded by Jed McCaleb (co-founder of cryptocurrency platforms), Vast is building space stations with private capital — no NASA CLD funding. Their concept art reflects a different design language than the other three programs.
What the concept art shows: Haven-1 is a compact single-module station, roughly the size of a school bus, designed for short-duration crewed missions of up to 30 days. The concept art depicts a minimalist, SpaceX-influenced aesthetic — clean white surfaces, integrated displays, and a multi-function interior that serves as workspace, sleeping quarters, and observation deck. Haven-1 is designed to be visited by SpaceX Dragon capsules.
Haven-2 is far more ambitious. Concept renderings show a Starship-diameter station module (9 meters wide) with multiple decks connected by an open central corridor. The interior art shows artificial gravity concepts — a rotating section that could provide partial gravity for crew health. If built as rendered, Haven-2 would have more pressurized volume than any single ISS module.
Engineering behind the art: Haven-1 is the most near-term hardware. Vast has been moving quickly, with the module reportedly in advanced manufacturing. The single-module approach mirrors Starlab's philosophy — launch complete, no assembly required.
Haven-2's artificial gravity concepts are the most speculative element in any current station design. Rotating a spacecraft section to generate centripetal acceleration is well-understood physics but has never been implemented in an orbital habitat. The structural loads from rotation, the bearings connecting rotating and non-rotating sections, and the Coriolis effects on crew movement are real engineering challenges that concept art cannot address.
What these stations need: jobs in space station design
Space station development creates demand across multiple engineering disciplines. Here is what companies are hiring for in 2026:
| Discipline | Role Examples | Who is Hiring |
|---|---|---|
| Structures | Pressure vessel design, inflatable structures, composite analysis | Axiom, Sierra Space, Vast |
| ECLSS | Air revitalization, water recovery, thermal control | All four programs |
| Avionics | GN&C, power systems, data handling, communications | Blue Origin, Airbus, Vast |
| Human factors | Interior layout, crew workflow, habitability design | Axiom, Sierra Space |
| Systems engineering | Requirements, integration, verification and validation | All four programs |
| Software | Flight software, ground systems, mission planning | All four programs |
| Materials | Vectran fabrics, radiation shielding, MMOD protection | Sierra Space, Vast |
ECLSS engineers are in particularly high demand. Life support systems for space stations must recycle air and water with 90%+ efficiency for years without resupply — this is one of the hardest engineering problems in human spaceflight, and every station program needs these specialists.
The design philosophy spectrum
The four stations represent a clear spectrum from conservative to ambitious:
Most conservative: Starlab — single module, existing technologies, international consortium, ISS heritage Moderately ambitious: Axiom — incremental build, ISS-attached start, designer interiors, proven module architecture Ambitious: Orbital Reef — multi-module complex, inflatable habitats, mixed-use vision, complex on-orbit assembly Most ambitious: Vast Haven-2 — artificial gravity concepts, Starship-scale modules, private funding only
The stations most likely to fly on schedule are the ones with the simplest assembly requirements. Starlab and Haven-1 each require a single launch. Axiom's incremental approach de-risks by leveraging the existing ISS. Orbital Reef's multi-module assembly is the highest-risk architecture — but also the one with the most growth potential.
The gap between concept art and flight hardware is where aerospace careers happen. Every rendering shown by these companies represents thousands of engineering hours in structural analysis, thermal modeling, ECLSS design, and systems integration. If you are drawn to space station concept art, the path to working on these programs runs through mechanical engineering, aerospace engineering, systems engineering, or human factors — and the companies building these stations are hiring now.
