But that's not going to change orbital mechanics, which is what
determines if it stays up or not.

Plus, as far as I know, Progress and ATV could both dock and perform
reboosts even while ISS is unmanned. So even if ISS was in danger of
"coming down", there is still something we could do about it.

lack of pressurization would likely make any problem worse. lots of
systems may overheat without cooling air.


What lack of pressurization? You don't have to let all the air out
just because you're leaving, do you? If you can't keep air in it,
that's going to be REAL hard on the crew you're leaving up there,
isn't it?

If the crew does leave ISS, they'll surely shut all of the hatches
between modules so that if one does become depressurized, it won't
impact the others.

As usual Bob is worrying about the unlikely while simultaneously
thinking NASA and the Russians are both stupid and don't know how to
plan for such contingencies.
