Starlab design as of December 2025

NASA today announced that it has awarded Voyager Technologies a slot to fly a tourist mission to ISS in 2028.

The mission, named VOYG-1, is expected to spend as many as 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

Voyager 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 the launch provider for their flight.

Voyager is the lead company in the consortium that is building the Starlab station, a single very large module to be launched on SpaceX’s Starship.

At this moment three of the five commercial stations that are developing private space stations — Axiom, Vast, and Voyager — now have deals to fly such missions to ISS. The two remaining likely didn’t pass muster with NASA, for different reasons. Max Space is a late comer to this competition, only declaring that it is building its own station this year. Orbital Reef, led by Blue Origin and Sierra Space, is apparently a dead project, with neither company doing anything to sell its project for the past year or so.

In my rankings below of the five American commercial space stations presently in development, the first three are essentially tied at this point.

• 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. It also plans a manned mission to ISS in ’28. The company is already testing an unmanned small demo module in orbit. It has also made preliminary deals with Colombia, Uzbekistan, Japan, and the Maldives for possible astronaut flights to Haven-1. It has also raised more than a billion in cash for this work.
• 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 $450 million in private investment capital. The development of its first two modules has been proceeding, though the first module launch is now delayed until 2028. It has also signed Redwire to build that module’s solar panels.
• 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.
• 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.
