In its continuing effort to sign customers (and earn income) outside of NASA funding, the space station startup Vast today announced it has signed a deal with the Czech Republic to fly one of its astronauts to ISS on its planned mission there in 2027.

This agreement builds on the memorandum of understanding that Vast, and the Czech Republic signed in 2024. Subject to Multilateral Crew Operations Panel (MCOP) review and approval, Aleš Svoboda, one of the 12 members of the astronaut reserve selected by ESA in November 2022, will serve as the mission pilot. The MCOP’s decisions are reached through a consensus among representatives from all five space station partners: NASA, ESA, Roscosmos, the Japan Aerospace Exploration Agency, and the Canadian Space Agency. Pending approval, Aleš Svoboda will become the first Czech astronaut to visit the International Space Station. Svoboda is planned to join ESA Astronaut Thomas Pesquet who is the named Commander for the mission.

Pesquet is a French astronaut flying under the deal France signed with Vast only two weeks ago.

Unlike the Starlab and Axiom stations, Vast is building its single module demo station, Haven-1, with no government funds. It is not only flying this private two-week mission to ISS, it is also planning four two-week missions to Haven-1 during if three year mission, once it launches next year. All will use SpaceX’s Falcon 9 as a launch provider, with one of its Dragon capsules for crew transport.

Below is my updated ranking of the five American space stations presently under development:

• Haven-1 and Haven-2, being built by Vast, with no NASA funds. The company plans to launch its single module Haven-1 demo station in 2027 for a three-year period during which it will be occupied by at least four 2-week-long manned missions, one of which will include a French astronaut. It planned manned mission to ISS in ’28 will also include both a French and Czech astronaut. It has also made preliminary deals with Lithuania, Colombia, Uzbekistan, Japan, the Czech Republic, and the Maldives for possible astronaut flights to Haven-1. It has raised more than a billion in cash for this work, and has already tested an unmanned small demo module in orbit.
• Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with extensive partnership agreements with the European Space Agency, Mitsubishi, and others. Though no construction has yet begun on its NASA-approved design, it has raised $383 million in a public stock offering, the $217.5 million provided by NASA, and an unstated amount from private capital. It has also begun signing up station customers, as well as a number of companies to build the station’s hardware. It also plans a mission to ISS in ’28.
• Axiom, being built by Axiom, has launched four tourist flights to ISS, with the fourth carrying government passengers from India, Hungary, and Poland. A fifth mission is now planned for ’27. The company has now raised $625 million in private investment capital. Thales Alenia in Europe has been building its first two modules, with the first scheduled to launch in 2028. The company has also now established a subsidiary in Europe as well as signed Redwire to build that module’s solar panels.
• Thunderbird, proposed by the startup Max Space. It is building a smaller demo test station to launch in ’27 on a Falcon 9 rocket, and has begun work on its manufacturing facility at Kennedy in Florida. Its management includes one former NASA astronaut and one former member of the Bigelow space station team that built the first private orbiting inflatable modules, Genesis-1, Genesis-2, and BEAM (still operating on ISS).
• Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. This station looks increasingly dead in the water. Blue Origin has built almost nothing, as seems normal for this company. And while Sierra Space has successfully tested its inflatable modules, including a full scale version, its reputation is soured by its failure in getting its Dream Chaser cargo mini-shuttle launched to ISS.
