I find it odd that if damage had/has occurred that would warrant a
rescue mission then how can you possibly even consider launching the
Atlantis shuttle. Surely you are then running the risk of just
compounding the problem by possibly having two damaged shuttles in
orbit.
And anyway, what would be the need to launch a second shuttle any way,
they can stay on the ISS for quite some time and come back via Soyuz.
