> I would call the ISS a permanent station.

Since the ISS end of life is scheduled for 2030 - just four years from now - I really would not call it "permanent". Even if gets a few years reprieve, that's quite temporary.

There comes a point with buildings and with space stations where tearing down and completely replacing them is a better and cheaper option than repairing or extending them. The ISS is nearing that point.

Something that was permanent and is now scheduled for destruction is still permanent, no?

Or can we at least agree that it was permanent at some point of its life?

Sure, but that's the case for everything, including permanent things. My house won't be around forever, I would still call it a permanent housing.

No, the ISS never was permanent. It had a limited lifespan from the outset. It's actually beyond the original 15-year life. But it is not indefinite.

That's true, in the sense that "A word means whatever I choose it to mean". If you were in a flat in an apartment building scheduled for demolition in 2030, would you call that "permanent housing" ?

I think it depends on the context, but for a home, I would still call it permanent housing if it’s supposed to be demolished in 2070, but probably not by 2030.

I’m not sure the bases in Antarctica all have a set lifetime so it doesn’t really matter for the original point.
