As for servicing HST, I'm still curious how that is going to shake
out. That crew won't have the option of sheltering at ISS (I don't
know whether there are plans being worked to make a rescue by a second
shuttle - or even perhaps Soyuz - feasible. It is harder than the ISS
case because the wounded shuttle has to provide life support
unassisted long enough for rescue craft to arrive).

Soyuz can't do it. HST's orbital inclination is too low to be reached from
Baikonur, and the mission will be long before the Soyuz pad at Kourou will
be capable of accommodating a manned Soyuz. The rescue would have to be
done by a second shuttle.

It gets even more complicated when you consider that the HST mission will
likely be no earlier than April 2008, a whole year after ESMD's need date
for starting the conversion of pad 39B to CEV/CLV. If those dates hold up,
the rescue mission will have to launch from the same pad the crippled
mission launched from just days earlier.
