NASA announced on April 2, 2025, they would be seeking bids for two private missions to the ISS.[2] All prior private ISS contracts had been performed by Axiom.[lower-alpha 1] Both upcoming missions would spend 14 days at the ISS.[2] On January 30, 2026, NASA announced that Axiom had won one of the two missions for Ax-5, targeted to launch no earlier than January 2027.[1] The other mission was awarded to Vast while a third mission, VOYG-1 by Voyager Technologies, was announced on April 16.[3]
Payload integration will be performed by Voyager.[4] Ax-5, as with prior missions, will develop the techniques required for Axiom employed private astronauts to dock with their own private space station, the in-development Axiom Station.[4] The funds from the awarded contract, alongside a restructuring of Axiom's debt, will help Axiom continue to finance their Extravehicular Mobility Unit that they are developing for NASA for use on the Moon during the lunar landing scheduled for Artemis IV.[5]
Crew
The mission will carry a professionally trained commander and three private astronauts.
The Czech government had signed a memorandum of understanding with Axiom on September 6, 2024, to launch a Czech astronaut, ESA astronaut Aleš Svoboda, on a future mission as part of the "Czech Journey to Space".[6] A week later the Portuguese government announced that they had signed a similar memorandum to send Emiliano Ventura to space.[7][8]
Also in 2024 the British government announced they plan to buy all four seats on an upcoming Axiom mission for astronauts Meganne Christian, Rosemary Coogan, John McFall, and Timothy Peake.[6]
On July 2nd, 2025, CONAE, the Argentine space agency, announced that they had also signed a memorandum of understanding with Axiom to launch Noel de Castro into space on a future Axiom mission in 2027.[9]
Upon announcement of the mission, Axiom said they would send four different crew proposals to NASA who will select the final crew.[1]

Mobile page views accounted for 60% to 70% of all page views from 2020 through 2025. Briefly, these templates are not included in articles because 1) they are not well designed for mobile, and 2) they significantly increase page sizes—bad for mobile downloads—in a way that is not useful for the mobile use case.
