Vast Advances Haven-1 Into Integration Phase
The commercial space industry stands at a significant juncture as Vast Space transitions its flagship project, Haven-1, from structural manufacturing to the complex integration phase. This development marks a pivotal shift in the lifecycle of the spacecraft, moving it from a passive metal hull to a functional orbital habitat. Occurring at the company’s headquarters in Long Beach, California, this phase represents the final assembly period before environmental testing and eventual launch.
The integration phase is an intricate process where the disparate components of the space station – propulsion systems, avionics, life support mechanisms, and crew interfaces – are installed into the primary pressure vessel. For Vast Space, this milestone validates its aggressive vertical integration strategy and rapid development timeline. The company, founded by Jed McCaleb, seeks to accelerate humanity’s expansion into the cosmos by deploying affordable, artificial-gravity-capable stations. Haven-1 serves as the pathfinder for this broader vision, acting as a standalone crewed outpost and a technology demonstrator for future, larger structures.
The Significance of the Integration Phase
In aerospace engineering, the integration phase is the bridge between structural fabrication and system-level validation. Prior to this stage, the spacecraft exists as a collection of separate parts: a pressure shell, machined panels, and boxes of electronics. Integration brings these elements together to form a cohesive system. For Haven-1, this process involves the precise installation of thousands of components inside the 4.4-meter diameter hull.
Technicians and engineers are currently routing kilometers of cabling for power and data, installing plumbing for thermal control and environmental systems, and mounting the avionics hardware that will control the station in orbit. This phase also includes the installation of the propulsion system, provided by Impulse Space, which is essential for orbital maintenance and maneuvering.
The speed at which Vast Space reached this stage is notable. By leveraging in-house manufacturing for the primary structure – a process that transitioned from initial design to a flight-qualified aluminum hull in under two years – the company has bypassed many of the supply chain bottlenecks that traditionally delay aerospace programs. The arrival of the flight hull at the integration floor signals that the structural qualification tests, including pressure and load testing, successfully validated the design’s integrity.
Haven-1: Architecture and Capabilities
Haven-1 is designed as a single-module space station capable of supporting a crew of four for missions lasting up to 30 days. Its architecture prioritizes compatibility with the SpaceX Dragon spacecraft, which will serve as the primary transport vehicle for astronauts visiting the station.
Primary Structure and Dimensions
The station features a cylindrical pressure vessel optimized for launch inside the payload fairing of a Falcon 9 rocket. The switch to an aluminum alloy for the primary structure, a decision driven by the need for rapid manufacturing and mass optimization, allows the station to maximize habitable volume while staying within the lift capacity of the launch vehicle.
| Parameter | Specification |
|---|---|
| Length | 10.1 meters |
| Diameter | 3.8 meters (4.4 meters external) |
| Pressurized Volume | 80 cubic meters |
| Habitable Volume | 45 cubic meters |
| Total Mass | ~14,000 kg |
| Orbit | Low Earth Orbit (LEO), ~500 km altitude |
| Inclination | 51.6 degrees |
The interior volume is divided into distinct zones: a common area for social interaction and dining, a laboratory section for scientific payloads, and private crew quarters. This layout attempts to balance the psychological needs of the crew with the functional requirements of a research platform.
The Observation Window
A distinguishing feature of the Haven-1 design is its large domed window. Measuring 1.1 meters in diameter, this window provides a panoramic view of Earth, intended to offer the “Overview Effect” to commercial astronauts and researchers. Integrating such a large transparent aperture into a pressure vessel presents significant engineering challenges, particularly regarding seal integrity and micrometeoroid protection. The integration team is currently installing the multi-layer glass assembly, which includes protective shutters and impact-resistant panes to ensure safety during the station’s operational life.
Docking and Ingress
The station utilizes an International Docking System Standard (IDSS) compatible port, located at the forward end of the module. This port allows the Dragon spacecraft to dock securely, creating a pressurized tunnel for crew transfer. During the integration phase, the docking mechanism undergoes rigorous alignment checks to ensure it can capture and seal against the visiting vehicle within millimeter tolerances.
Essential Subsystems Integration
The core functionality of Haven-1 relies on the successful integration of its active subsystems. These systems provide the power, propulsion, and environment necessary to sustain human life and station operations.
Propulsion and Attitude Control
Haven-1 employs a hybrid propulsion strategy. For major orbital maneuvers and deorbiting capabilities, the station relies on a propulsion system developed in partnership with Impulse Space. This system uses non-toxic, storable propellants, simplifying the loading process and reducing safety hazards during ground processing.
For fine attitude control, the station utilizes a set of Control Moment Gyroscopes (CMGs) and reaction wheels. These devices spin at high speeds to generate torque, allowing the station to rotate and stabilize without consuming propellant. The integration of these heavy, high-speed rotational components requires precise balancing and vibration isolation mounting to prevent structural resonance.
Power Generation and Distribution
Power is generated via body-mounted and deployable solar arrays. The integration phase involves the installation of the photovoltaic panels and the complex harness wiring that routes power to the battery banks. Haven-1 is designed to generate approximately 15 kilowatts of power, sufficient to support the life support systems, avionics, and a suite of energy-intensive scientific experiments.
The battery system, composed of lithium-ion cells, provides power during the orbital night. Technicians are currently installing these battery modules into thermally controlled compartments to ensure they operate within their optimal temperature range, preventing degradation and ensuring safety.
Environmental Control and Life Support System (ECLSS)
Perhaps the most complex system being integrated is the ECLSS. Unlike short-duration capsules, Haven-1 must maintain a breathable atmosphere, regulate humidity, remove carbon dioxide, and manage waste for extended periods. The system is regenerative to a degree but relies on consumables for its initial 30-day missions.
The integration team is installing the air revitalization racks, which include CO2 scrubbers and trace contaminant control units. The thermal control system, consisting of internal fluid loops and external radiators, is also being assembled. This system transports waste heat from the avionics and crew to the radiators, where it is rejected into space.
The Human Experience: Interiors and Habitat
Vast Space has placed a strong emphasis on the interior design of Haven-1, employing industrial designer Peter Russell-Clarke to create a habitat that is both functional and comfortable. The integration of the interior elements marks the transformation of the engineering structure into a home.
Fire Safety and Materials
All interior materials, from the wall panels to the sleeping bags, must undergo strict flammability testing. During integration, these fire-resistant materials are installed over the aluminum primary structure, providing acoustic insulation and a softer tactile interface for the crew. The station features a soft-goods interior architecture, which reduces the risk of injury during movement in microgravity and dampens the noise from fans and pumps.
Sleeping Quarters and Gravity Experiments
One of the experimental objectives of Haven-1 is to test systems for future artificial gravity stations. While Haven-1 itself is not a rotating ring station, Vast Space plans to conduct experiments where the combined Haven-1 and Dragon stack spins end-over-end to generate partial gravity.
To support this, the crew quarters are designed to accommodate sleeping in different orientations. The sleeping system is being integrated with restraints and padding that function effectively in both microgravity and the simulated lunar gravity conditions generated during the spin experiments. This data is essential for the development of Haven-2 and subsequent stations that will rely on rotation for long-term crew health.
Connectivity and Communications
Connectivity is a primary requirement for modern commercial spaceflight. Haven-1 is being outfitted with Starlink laser terminals, enabling high-speed, low-latency internet access. This system allows the crew to communicate with family, stream video, and transmit large scientific data sets in near real-time. The integration of these optical terminals involves precise alignment of the external optical heads and the installation of the internal modems and routers that distribute Wi-Fi throughout the cabin.
Scientific and Commercial Capabilities
Beyond space tourism, Haven-1 functions as a commercial laboratory. The station provides specific slots for scientific payloads, offering researchers access to the microgravity environment.
The Haven-1 Lab
The “Haven-1 Lab” allows for the integration of ten Middeck Locker Equivalent (MLE) payloads. These standard sized lockers are compatible with existing hardware used on the International Space Station, reducing development costs for customers.
| Payload Interface | Capability |
|---|---|
| Power per Slot | 100 W continuous (28 VDC) |
| Data Connection | Gigabit Ethernet via Starlink |
| Cooling | Forced air convection |
| Mass Capacity | 30 kg per locker |
| Crew Interaction | Available for setup and monitoring |
Partners such as Redwire and the European Space Agency (via commercial agreements) are preparing payloads for the inaugural mission. The integration team at Long Beach is currently installing the power and data backplanes that will support these experiments, verifying that the station can deliver the promised resources to the payload racks.
Strategic Partnership with SpaceX
The feasibility of Haven-1 is intrinsically linked to the partnership between Vast Space and SpaceX. This collaboration extends beyond simple launch services. SpaceX provides crew training, spacesuits, and the Dragon spacecraft that serves as the station’s lifeboat and transport.
During the integration phase, SpaceX engineers work closely with Vast Space personnel to ensure the compatibility of the docking systems and life support interfaces. The environmental control systems of Haven-1must seamlessly handshake with Dragon when docked, allowing air circulation between the two vehicles. This interoperability is being verified through joint tests and software simulations running in parallel with the hardware integration.
Comparison with Other Commercial Stations
Haven-1 is competing in a growing market of commercial Low Earth Orbit (LEO) destinations. However, its strategy differs significantly from competitors like Axiom Space or the Orbital Reef project. While others propose large, modular stations similar to the International Space Station from the outset, Vast Space has opted for a smaller, single-module approach to reach orbit faster.
| Feature | Vast Haven-1 | Axiom Station (Phase 1) | Orbital Reef |
|---|---|---|---|
| Architecture | Single Module (Free-flyer) | Attached to ISS (initially) | Large Modular Array |
| Primary Material | Aluminum | Aluminum-Lithium | Mixed/Inflatable components |
| Launch Vehicle | Falcon 9 | Heavy Lift Vehicles | New Glenn |
| Gravity Capability | Spin experiment (Whole stack) | Microgravity only | Microgravity only |
| Target Timeline | Flight Integration Active | Modules in construction | Design/Development |
This “simple and fast” philosophy allows Vast Space to iterate on its technology in orbit. The lessons learned from the integration and operation of Haven-1 will directly inform the design of the larger Haven-2, which is intended to be a direct successor to the ISS.
Manufacturing and Supply Chain
The transition to integration highlights the success of the vertical integration model adopted by Vast Space. By manufacturing the majority of components in-house – including the batteries, avionics, and primary structure – the company controls the quality and schedule of the build.
The Long Beach facility has been outfitted with advanced machining centers, friction stir welding machines, and cleanrooms specifically for this purpose. This capability allows for rapid prototyping and modification. If an issue is discovered during integration, the engineering team can redesign and manufacture a bracket or interface plate in days rather than waiting weeks for an external supplier.
Future Outlook: Beyond Integration
Following the completion of the integration phase, Haven-1 will undergo a battery of environmental tests. These include thermal vacuum testing, which simulates the extreme temperature cycles of space, and vibration testing, which ensures the station can survive the violent acoustic environment of a rocket launch.
Success in these tests will lead to the shipment of the station to the launch site. The upcoming launch of Haven-1 will demonstrate whether a startup, funded largely by private capital and driven by a vision of artificial gravity, can execute a complex aerospace program on a timeline that outpaces traditional government projects.
The current activity on the integration floor is more than just assembly; it is the physical realization of a new operating model for space exploration. By advancing Haven-1 into this phase, Vast Space has moved from the realm of paper concepts to the reality of flight hardware, placing it at the forefront of the race to commercialize Low Earth Orbit.
Summary
Vast Space has successfully advanced the Haven-1 space station into the integration phase at its Long Beach facility.
