Two Big Falcon Spaceships docked at a conceptual station in the 2020s, one carrying crew and one Cargo variant delivering the last major module for the stations construction.Thinking about what sorts of habitat modules might be optimal for BFS-launch. The payload bay is sorta weirdly shaped, so to make full use of its volume, the modules would have to be mostly conical, with a short cylindrical section at the bottom. By pure coincidence, the large modules in Lockheed Martin's Mars Base Camp architecture are nearly the exact size that can fit in BFS, just a tad short. Each of those would be some 300 m^3 of pressurized volume, giving a total station volume some 2.5x that of ISS.I was inspired some as well by this early Shuttle concept from the 70s: 1.bp.blogspot.com/--10VRiEx6zM…
