Recent developments have marked a significant achievement for Vast as the company moves closer to launching its first private commercial space station. The completion of testing for the Haven-1 qualification article in Mojave, California, represents a pivotal step in realizing Vast’s ambitious plans for low-Earth orbit (LEO) operations.
The successful testing of the Haven-1 qualification article reinforces Vast’s timeline, aiming for a launch aboard a SpaceX Falcon 9 rocket no earlier than May 2026. This timeline is important, as it aligns with NASA’s upcoming selection process for partners to maintain U.S. presence in LEO post-International Space Station (ISS) deorbiting, scheduled for 2030.
Strategic Initialization and Growth
- Vast’s CEO, Max Haot, emphasized the company’s need for profitability to sustain its operations, pointing out the importance of securing a NASA contract as an anchor customer. “If we don’t win [the contract], we don’t think we can even exist, so it’s a matter of survival,” Haot said.
- The Haven-1 mission serves as a preliminary testbed for the larger Haven-2 space station, which Vast hopes to position as a replacement for the ISS. By demonstrating a successful crewed mission with Haven-1, Vast aims to improve its chances in NASA’s selection process for the Commercial Low Earth Orbit Destination Phase II Contract.
The Haven-1 space station is designed as a single-module platform. Although it will not remain permanently crewed, it is expected to host multiple missions throughout its operational lifespan of two to three years. That’s a departure from traditional space station designs, emphasizing a more modular and flexible approach to space use.
Engineering Solutions and In-House Manufacturing
- Vast’s strategy includes extensive in-house manufacturing, allowing for faster production timelines. This method is essential for designing complex components, saving both time and resources as compared to relying on external supply chains.
- For the construction of Haven-1’s main shell, the company evaluated two materials: stainless steel and aluminum, ultimately transitioning to aluminum for its preferred balance of strength and weight.
Haot explained the engineering philosophy behind Haven-1’s design. “The lower the center of gravity, the better the launch,” he noted. This principle drove design considerations such as the placement of propellant tanks, optimizing weight distribution to maximize launch efficiency.
Operational Dynamics of Haven-1
- The station is not intended for a permanent human presence. Instead, it will facilitate crewed missions using SpaceX’s Crew Dragon, with each mission planned for approximately two weeks.
- A key challenge for crewed missions lies in managing consumables, especially considering the limited payload capacity of the Dragon capsule. Crews will need to ensure they bring enough supplies to support their stay, with the logistics considerably differing from the ISS resupply model.
Vast is aware of the challenges ahead, particularly regarding life support systems. The company has ordered carbon dioxide scrubbers from SpaceX to handle the atmospheric needs of the crew during their missions. To improve sustainability, Vast aims to develop a closed-loop life support system by the time of Haven-2’s operation.
Future Outlook and Technological Innovations
- The design of Haven-2 will incorporate modular features that allow for redundancy and maintainability. Each module will be capable of standalone operation, providing resilience to the overall station.
- Vast plans to launch a series of modular components on SpaceX’s Falcon Heavy to gradually build out the station architecture by 2032. This phased approach not only reduces initial costs but also allows for iterative improvements based on operational feedback.
To demonstrate its technological capabilities, Vast is also planning to launch a 500 kg satellite in an upcoming SpaceX rideshare mission, which will evaluate critical components and systems intended for the Haven-1 station. “It’s designed to test all of our propulsion, avionics, RF systems, all the subsystems [of Haven-1],” Haot explained, indicating a commitment to rigorous testing and iteration.
As the commercial space industry evolves, Vast’s innovative plans for the Haven-1 and Haven-2 stations exemplify a shift towards private initiatives in LEO, capturing the potential for advancements in space exploration and habitation.
