Vast’s Haven 1 Aims to Help Build the Next Era of Commercial Space Stations

The International Space Station (ISS) has been a permanent human presence in low Earth orbit for more than two decades, supporting scientific research and international cooperation. But as plans move forward for the station’s eventual retirement, private companies are developing alternatives designed to keep people and research facilities operating in orbit.

One of those companies is California-based Vast, which is developing Haven 1, a single-module commercial space station intended to become an early example of privately operated orbital infrastructure.

Vast is building Haven 1 at its Long Beach, California, facility, where engineers are working on the station’s primary structure and other systems. The company’s approach emphasizes in-house manufacturing, with much of the structural work taking place under the same roof.

Building Haven 1 From the Ground Up

According to the video transcript, Vast’s Long Beach facility handles several stages of Haven 1’s structural manufacturing process. Aluminum material is milled, rolled and welded before being tested as the company works toward producing flight-ready hardware.

The facility is part of Vast’s broader effort to maintain greater control over the station’s development. Rather than relying entirely on a large network of outside suppliers, the company says it is pursuing a high degree of vertical integration across areas such as structures, propulsion and avionics.

Haven 1 is designed as a relatively compact orbital platform. The station is expected to measure roughly 10 meters long and 4 meters in diameter, making it considerably smaller than the ISS.

The first module is intended primarily for shorter-duration crewed missions and commercial activities. Its development also represents a test of whether privately built space infrastructure can eventually support a larger commercial ecosystem in low Earth orbit.

A Different Approach to Station Interiors

Vast is also taking a different approach to the interior design of its station.

The ISS has evolved over decades and contains a dense arrangement of equipment, cables, research hardware and life-support systems. Haven 1, by contrast, has been designed with a more streamlined interior in mind.

The company has worked with veteran astronaut Drew Feustel, who spent 197 days in space, on aspects of the crew experience. The goal is to make the limited interior space practical while improving the day-to-day environment for astronauts.

The planned interior includes integrated cable management, crew sleeping areas and dedicated spaces for work and research. According to the transcript, the sleeping stations will use a pressure-regulated air bladder system intended to provide a more supportive sleeping experience in microgravity.

These features may appear relatively small compared with the station’s major engineering systems, but they reflect a broader issue facing commercial space stations: making orbital habitats functional and comfortable enough for people who may spend days or weeks aboard them.

The Business Case for Commercial Stations

The development of Haven 1 comes as NASA and other space agencies look toward a future in which government-operated facilities are joined, and eventually potentially supplemented, by commercial platforms.

Vast is backed by entrepreneur Jed McCaleb, who has provided financial support for the company’s development. The company’s long-term business model is based on treating orbital infrastructure as a commercial service rather than solely as a government-funded project.

Vast has discussed several potential customers for its stations, including private companies, research organizations, sovereign nations and government space agencies.

The company also intends to use commercial launch services to put Haven 1 into orbit. The transcript identifies SpaceX’s Falcon 9 as the launch vehicle planned for the mission.

One of Vast’s stated objectives is to reduce the cost of building and operating space infrastructure through repeatable manufacturing. The idea is that future stations could be produced more like standardized commercial products than individual government spacecraft.

However, commercial space stations remain a challenging business. Companies must overcome significant engineering, launch, safety and operational costs while also developing enough demand for research, crew missions and other activities.

What Comes After Haven 1?

Haven 1 is not intended to be the end of Vast’s plans.

The company has outlined a longer-term vision involving larger, multi-module space stations. Future concepts could incorporate rotating sections designed to create artificial gravity, although those ambitions are considerably more complex than the initial Haven 1 mission.

For now, Haven 1 represents a smaller and more immediate step.

Its development comes at an important point for the human presence in low Earth orbit. NASA is preparing for the eventual end of the ISS era while supporting the development of commercial successors. Several private companies are pursuing different concepts, making the coming years a significant period for the future of orbital infrastructure.

Whether Haven 1 becomes a successful commercial platform will depend on more than simply reaching orbit. The station will need to operate safely, attract customers and demonstrate that privately developed habitats can provide reliable services at a sustainable cost.

For Vast, the work underway in Long Beach is therefore about more than constructing a single space station. It is an attempt to demonstrate a new model for building and operating infrastructure beyond Earth.

If successful, Haven 1 could become an early milestone in the transition from government-dominated orbital facilities toward a broader commercial presence in space.
