Docking. A rotating airlock can; assembly by Canadarm3-class remote arms; androgynous 3 m berthing ports with 2 m doors, self-bolting and rotatable 90°. Specs follow Nexus Aurora OCS lamontagne, 2023-01-19.
A 3 m UBM berthing port with a 2 m door that rotates at 1–5 rpm only while a ship is docked lamontagne, 2023-01-24.
Cost. ~60 Starship launches at $10M ≈ $600M of launch lamontagne, 2023-01-19.
Testing. Cans can be tested in 0 g first. A baton of cans to find the best rpm and g lamontagne, 2023-01-20.
Video. A 3 rpm can station with rotating airlock lamontagne, 2023-01-23. Panels moved to the "bottom" (sun side); 0.6 g chosen from the earlier baton test station; momentum wheels in the centre modules lamontagne, 2023-01-22; lamontagne, 2023-01-23.

With no ship docked, the docking configuration is unstable, so momentum wheels or thrusters are needed lamontagne, 2023-01-20.
