NASA has selected Vast, a space technology company, to conduct the sixth private astronaut mission to the International Space Station (ISS). The mission, targeted for launch no earlier than summer 2027 from Florida, marks Vast’s first crewed mission to the orbiting laboratory and underscores the agency’s commitment to expanding commercial opportunities in low Earth orbit. This initiative is a key part of NASA’s broader strategy to foster a thriving commercial space economy and prepare for future missions to the Moon, Mars and beyond.
The agreement between NASA and Vast, announced on February 12, 2026, builds on a growing trend of private companies sending astronauts to the ISS. These missions aren’t simply about tourism; they represent a significant shift in how space exploration is funded and executed, opening doors for new technologies and research opportunities. NASA Administrator Jared Isaacman emphasized that private astronaut missions “create opportunities for new ideas, companies, and capabilities that further enhance American leadership in low Earth orbit,” according to a NASA press release.
Vast, based in Long Beach, California, is actively developing next-generation space stations. This mission to the ISS will serve as a crucial testbed, generating invaluable insights into the infrastructure and processes required for human spaceflight, particularly as the company works towards its goal of launching its own commercial space station, Haven-2. The company views leveraging the remaining operational life of the ISS with science-focused missions as a critical step in transitioning to these fully commercial platforms.
Mission Details and Crew Selection
The Vast private astronaut mission is expected to last up to 14 days aboard the ISS. The exact launch date will depend on the overall schedule of spacecraft traffic to and from the station and other logistical considerations. SpaceX’s Falcon 9 rocket will be used to launch the crew in a Dragon spacecraft, as previously announced by both companies.
Currently, Vast is preparing a list of four proposed crew members to submit to NASA and its international partners for review and approval. Once confirmed, the crew will undergo extensive training alongside NASA astronauts, international partners, and SpaceX personnel to prepare for the demands of spaceflight. The training will cover all aspects of mission operations, including spacecraft systems, emergency procedures, and scientific experiments.
Focus on Research and Commercialization
Vast is planning a robust portfolio of scientific research for the mission, with a particular emphasis on biology, biotechnology, physical sciences, human research, and technology demonstrations. Last year, the company issued a call for research proposals, seeking innovative projects that could benefit from the unique environment of the ISS. This commitment to research highlights the potential for private missions to contribute meaningfully to scientific advancement.
Dana Weigel, manager of the International Space Station Program at NASA’s Johnson Space Center in Houston, stated that the ISS “plays an essential role in shaping the future of low Earth orbit.” She added that hosting private astronaut missions “helps accelerate innovation, opens new commercial pathways, and advances research strengthening the foundation of a thriving space economy.”
Expanding Access to Space
This mission represents a continued effort by NASA to broaden access to space and encourage private sector investment in space technologies. The agency has been actively working to create a sustainable commercial space ecosystem, believing that competition and innovation will drive down costs and accelerate the pace of discovery. The selection of Vast for this mission is a testament to the company’s capabilities and its vision for the future of space exploration.
The growing number of private astronaut missions also raises questions about the future role of government-funded space programs. While NASA continues to pursue ambitious goals like returning to the Moon with the Artemis program and eventually sending humans to Mars, commercial partnerships are becoming increasingly important for maintaining a presence in low Earth orbit and developing new space technologies.
Haven-2: Vast’s Vision for a Commercial Space Station
Vast’s long-term goal is to build and operate Haven-2, a multi-module, continuously crewed commercial space station. The experience gained from this ISS mission will be invaluable in preparing for the development and operation of Haven-2, which is intended to succeed the ISS as a primary destination for research, manufacturing, and tourism in low Earth orbit. The company believes that a commercially owned and operated space station will be more flexible and responsive to the needs of its customers.
The next step for Vast is submitting its proposed crew members to NASA for review. A specific launch date will be announced pending spacecraft traffic and final mission preparations. Updates on the mission’s progress can be found on the Vast Space website and through NASA’s official channels.
As private companies like Vast continue to push the boundaries of space exploration, the future of human presence in orbit looks increasingly dynamic and innovative. This mission to the ISS is not just a single event, but a stepping stone towards a new era of commercial spaceflight and a more accessible future for all.
