NASA and Vast have signed an order for the sixth private astronaut mission to the International Space Station, targeted to launch no earlier than summer 2027 from Florida.
This private astronaut mission marks the company’s first selection to the orbiting laboratory, underscoring NASA’s ongoing investment in fostering a commercial space economy and expanding opportunities for private industry in low Earth orbit.
“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,” said NASA Administrator Jared Isaacman. “We’re proud to welcome Vast to this growing community of commercial partners. Each new entrant brings unique strengths that fuel a dynamic, innovative marketplace as we advance research and technology and prepare for missions to the Moon, Mars, and beyond.”
The mission is expected to spend up to 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.
“The International Space Station plays an essential role in shaping the future of low Earth orbit,” said Dana Weigel, manager, International Space Station Program at NASA’s Johnson Space Center in Houston. “By hosting private astronaut missions, the station helps accelerate innovation, opens new commercial pathways, and advances research strengthening the foundation of a thriving space economy.”
Vast will submit four proposed crew members to NASA and its international partners for review. Once approved and confirmed, they will train with NASA, international partners, and SpaceX for their flight. The company has contracted with SpaceX as launch provider for transportation to and from the space station.
“Vast is honored to have been selected by NASA for the sixth private astronaut mission to the International Space Station,” said Max Haot, CEO of Vast. “Leveraging the remaining life of the 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.”
The company will purchase mission services from NASA, including crew consumables, cargo delivery, storage, and other in-orbit resources for daily use. NASA will purchase the capability to return scientific samples that must remain cold during transit back to Earth.
NASA made the selection from proposals received in response to its March 2025 NASA Research Announcement.
Missions aboard the International Space Station, including private astronaut missions, help advance scientific knowledge and demonstrate new technologies in the unique microgravity environment. These commercial efforts in low Earth orbit are helping develop capabilities and technologies that could support NASA’s long-term goals for missions beyond low Earth orbit, including deep space exploration to the Moon and eventually to Mars through the agency’s Artemis campaign.
