What We Do
Vast is developing next-generation space stations to ensure continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and unlocking a new space economy for government, corporate, and private customers. Using an incremental, hardware-rich and low-cost approach, Vast is rapidly developing its multi-module Haven Station. Haven Demo’s 2025 success made Vast the only operational commercial space station company to fly and operate its own spacecraft. Next, Haven-1 is expected to become the world’s first commercial space station when it launches in 2026, followed by additional Haven modules to enable permanent human presence by 2030. With more than 1,000 employees at its Long Beach, California headquarters and over a billion dollars in private capital invested, Vast has built the facilities required to manufacture and operate America’s next space station. The company plans to develop future habitats for the Moon and Mars, dedicated space stations for government partners, and other crewed systems that will unlock the expanding long-term space economy.
