Starlab? I guess that is the one with the most ESA buy-in through Airbus.
At this point I just hope someone gets something up and operational before the ISS retires. Seems like Vast will probably be first to get a module launched.
- 2027 Q1: Vast Haven-1
- 2027: Orbital Reef (contingent on Vulcan and/or New Glenn return to flight)
- 2028: Axiom Station
- 2028: Vast Haven-2
- 2028: Bharatiya Antariksh Station
- 2028: Russian Orbital Station (LOL, eat my hat Peter-Beck-style if this schedule holds)
- 2029: Starlab (contingent on Starship Cargo variant)
These timelines are getting kind of close to ISS retirement, and we haven't really seen hardware from anyone other than Vast and Axiom.
