Skylab's Size

Sincde the board's rather slow right now, I thought I'd ask something
I've been wondering about- at what point did ISS surpass Skylab as the
largest space station? Either in tonnage or habitable space? Did Mir
ever beat Skylab in either?

A rough estimate for Skylab gives a weight of 90 tonnes with a pressurised
volume of 361 cubic metres.

Mir with all additional modules added (Kvant, Kvant-2, Kristall, Spektr,
Priroda) was about 110 tonnes with a volume of 380 cubic metres.

Don't know about the ISS without more extensive research.

According to one of NASA's websites the ISS is currently 404,069 lbs and
15,000 cubic feet - which is about 183 tonnes & 424 cubic metres.

When did ISS exceed Mir?

The addition of the Destiny module in February 2001 enabled the ISS to
exceed the volume of Mir. ISS weight was then ~100 tonnes, about 10
tonnes less than Mir. During 2001 the addition of the Canadarm2 (4889kg)
and the Quest airlock (6064kg) would have pushed the weight past that
of Mir - the Quest module was launched July 12 2001.

That's right but the key is also how this space was organized.



The whole Skylab was almost one big cylinder, and Mir was made of a few
pieces that you've mentioned. All this leads to a different organization of
the useful working space. For example, we all saw astronauts in Skylab
spinning almost like in Kubrik's "2001: Space Odyssey" and in Mir it was all
very much cramped, especially at the end of its life.

....The amazing thing is that if you've been inside the 1G Trainer,
you'd see it's not as big as one might think from the pictures and
films. It's not cramped, but it's not cavernous. Like with the Apollo
CM, when you remove gravity, the perceived amount of usable space
almost triples because you're adding planes of reference that weren't
accessable due to gravity.

An interesting point!
