NASA Selects Vast for Sixth Private Mission to Space Station

NASA has announced a significant milestone in commercial spaceflight by selecting Vast, a California-based aerospace company, to conduct the sixth private astronaut mission to the International Space Station.[1][5] This selection represents a pivotal moment for both the company and NASA’s broader strategy to transition low Earth orbit operations to private industry.

The Mission Details

Vast’s private astronaut mission is targeted to launch no earlier than summer 2027 from Florida, with the crew expected to spend up to 14 days aboard the orbiting laboratory.[1][4] The company has already contracted with SpaceX for transportation, utilizing the Falcon 9 rocket and Crew Dragon spacecraft—the same vehicles that have supported previous commercial missions to the station.[1][6]

According to NASA, a specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.[5] Vast will submit four proposed crew members to NASA and its international partners for review and approval. Once confirmed, these astronauts will undergo training with NASA, international partners, and SpaceX before their flight.[1][5]

Strategic Importance for Vast

For Vast, this mission represents far more than just a trip to the space station. The company is leveraging this opportunity to gain critical insights into the infrastructure and processes required to safely conduct human spaceflight missions.[4] These lessons will directly inform the development of Haven-2, Vast’s proposed successor to the International Space Station—a multi-module, continuously crewed commercial space station that the company is positioning as a candidate to replace the ISS when it is decommissioned in 2030.[1][6]

Vast’s path to this selection was unconventional. The company was not chosen by NASA in its original pursuit of commercial space station developers, but it has been rapidly catching up through aggressive development and private investment.[1] In 2025, Vast successfully launched Haven Demo, a small spacecraft developed with SpaceX, demonstrating its operational capability as the only commercial space station company to fly and operate its own spacecraft.[4] The company plans to launch Haven-1, featuring a habitable area approximately the size of a moving truck, in 2027, with additional modules to enable permanent human presence by 2030.[1][4]

NASA’s Commercial Space Strategy

This selection underscores NASA’s commitment to fostering a dynamic commercial space economy in low Earth orbit. NASA Administrator Jared Isaacman emphasized the broader significance of private astronaut missions: “Private astronaut missions represent more than access to the International Space Station — they create opportunities for new ideas, companies, and capabilities that further enhance American leadership in low Earth orbit and open doors for what’s next.”[5]

The agency made this selection from proposals received in response to its March 2025 Research Announcement, demonstrating a competitive process designed to identify the most promising commercial partners.[5] By hosting these missions, the International Space Station accelerates innovation, opens new commercial pathways, and advances research that strengthens the foundation of a thriving space economy.[5]

Competition and Market Development

Vast is not alone in this emerging commercial market. Axiom Space continues to lead with four completed missions to the ISS and has signed an order for a fifth mission launching no earlier than January 2027.[1] Axiom was the first company to visit the station and has expanded the global community of space explorers, contracting astronauts from India, Hungary, Poland, Sweden, and Saudi Arabia for its previous missions.[1] Both companies have chosen SpaceX as their launch provider, reflecting the dominance of commercial spaceflight capabilities in the current market.

Science and Research Focus

Vast has developed an ambitious science and research portfolio for its mission, with a focus on biology and biotechnology, physical sciences, human research, and technology demonstrations.[1][4] The company previously announced a call for research proposals and has established an agreement with CASIS (Center for the Advancement of Science in Space) to enable increased throughput of high-quality science aligned with its strategy.[4] This emphasis on research-driven missions reflects NASA’s vision of using the remaining operational life of the International Space Station to advance scientific knowledge and develop technologies applicable to future deep space exploration.

Mission Services and Resource Sharing

Under the agreement, Vast will purchase mission services from NASA, including crew consumables, cargo delivery, storage, and other in-orbit resources.[1][5] In return, NASA will purchase the capability to return scientific samples that must remain cold during transit back to Earth—a practical arrangement that demonstrates the mutually beneficial nature of commercial partnerships in space.[5]

Looking Forward

Max Haot, CEO of Vast, captured the significance of this moment: “Leveraging the remaining life of the International Space Station with science and research-led commercial crewed missions is a critical part of the transition to commercial space stations and fully unlocking the orbital economy.”[1][5]

As NASA prepares for the eventual transition away from the International Space Station, missions like Vast’s demonstrate the agency’s confidence in private industry’s ability to maintain continuous human presence in low Earth orbit. These commercial efforts are developing capabilities and technologies that will support NASA’s long-term goals for deep space exploration, including missions to the Moon and Mars through the agency’s Artemis campaign.[5] With Vast’s selection, the commercial space economy enters a new phase of maturity and capability.
