If something does go wrong with Atlantis, we had better hope we can do
one quick turnaround on pad 39A.


...IIRC - and Jorge can confirm/deny this - we've done thought
exercises on this in the past over on .shuttle, and IIRC the quickest
"safe" turnaround was ~4 days. Of course, there's quite a few
x-factors here, such as when in the mission the need for a rescue
occurs, how much pad refurb can be done while the rescue vehicle is
being moved from either the VAB or the other pad, and how much can
either be slapdashed or skipped over altogether in order to get the
rescue shuttle launched in time.


More like 7, I think. But still possible. Both single-pad and dual-pad
plans were considered for 125/400 the first time around, and dual-pad won
out since it would take less labor on short notice, and there wouldn't be
much impact on Ares I-X. Now that the slip has increased the impact of
dual-pad ops for 125/400, single-pad is being reconsidered.

...Also, here's one I think we discussed, but I can't recall the
answer right off, is whether a Progress resupply could be launched to
Hubble orbit on short notice. This goes back to all the talk about
"What If?" in the weeks following Columbia, and the n00b/Press
questions about "why couldn't they just throw up food/water/fix-a-flat
kits/etc until another shuttle could be launched?"


No. Progress can't launch to 28.5 from Baikonur, Kourou has no handling
facilities for Progress, and no deal is being negotiated.
