This is interesting.
APAS is a pretty obsolete system, but it would be nice to have a docking standard for everyone, for safety and rescue reasons, and flexibility. I’m sure that Frank Wolf would have a hissy fit, though, if we were to share the NDS with the Chinese. The question is, would the station share an orbit with the ISS, or be in a different one? One of my dreams is seeing an actual community and infrastructure develop in one place, which again, would promote safety, and eliminate the idiotic (in my opinion, as I describe in my book) requirement for a “lifeboat” to evacuate everyone in the ISS all the way back to earth.
