Vast, a US-based space habitation technology company, has revealed its ambitious plans for Haven-2, a proposed successor to the International Space Station (ISS). Unveiled during the 75th International Astronautical Congress (IAC), Haven-2 represents a significant leap forward in commercial space station design and capabilities.
Timeline and Development
Vast aims to launch the first Haven-2 module by 2028, contingent on winning NASA’s Commercial Low Earth Orbit Destination (CLD) contract in 2026. The company plans a phased approach to building the full station:
- 2028: Launch of the first Haven-2 module
- 2029-2030: Deployment of three additional Haven-2 modules
- 2030-2032: Addition of a larger 7m diameter core module and four more Haven-2 modules
This gradual expansion will allow Vast to incrementally increase the station’s capabilities and accommodate growing research and habitation needs.
Design and Capabilities
Haven-2’s design builds upon Vast’s experience with Haven-1, its precursor single-module station set to launch in 2025. Key features of the completed Haven-2 station include:
- An unprecedented 3.8m diameter cupola window for Earth observation
- External payload hosting capabilities
- A robotic arm for space operations
- Visiting vehicle berthing capabilities
- An external payload airlock
- An extravehicular activity (EVA) airlock
Each Haven-2 module will be 5 meters longer than Haven-1, nearly doubling the available living space for astronauts. The station’s modular design allows for flexible expansion and customization to meet evolving needs.
Research and Manufacturing Facilities
The Haven-2 Lab is a cornerstone of the station’s scientific capabilities. It offers:
- State-of-the-art laboratory facilities for microgravity research and in-space manufacturing
- Larger payload and laboratory equipment accommodation compared to Haven-1
- Extensive integration options for experiments and specialized equipment
- Increased operational flexibility with ample power and thermal control
The lab meets all of NASA’s Basic Laboratory Capabilities for the CLD program, ensuring it aligns with the highest standards for orbital research facilities.
International Collaboration
Haven-2 is designed with international partnerships in mind. The station offers:
- Dedicated modules or lab facilities for international partners
- Seamless integration capabilities for diverse research projects
- Opportunities for global participation in microgravity research and technological advancements
This focus on collaboration aims to foster a truly global approach to space exploration and scientific discovery.
Technological Advancements
As Vast deploys additional Haven-2 modules, the company plans to introduce increasingly advanced and efficient life support technologies. This iterative approach will allow for continuous improvement of the station’s systems and capabilities over time.
Comparison to Other Proposals
Vast’s design for Haven-2 is projected to surpass other proposed on-orbit space stations in terms of volume, functionality, and operational efficiency. The company aims to set a new benchmark for next-generation space stations, ensuring that the United States and its international partners maintain leadership in the growing low Earth orbit economy.
Summary
Haven-2 represents an ambitious and comprehensive plan to create a successor to the ISS. With its modular design, advanced research capabilities, and focus on international collaboration, Haven-2 has the potential to play a crucial role in the future of space exploration and scientific discovery. As NASA prepares to retire the ISS in 2030, Vast’s proposal offers a promising vision for maintaining and expanding human presence in low Earth orbit. The phased development approach, cutting-edge facilities, and commitment to technological advancement position Haven-2 as a strong contender in the next generation of space stations.
