Not shuttle directly but what is the bay in the back of the VAB used for. I know it had Saturn V's roll out of it in years past I believe but not sure now. Thanks
that is where the ET's are processed and a contingency shelter for a shuttle stack
To add, right now, the non-stacking High Bays (High Bays 2 and 4) are used for the following:
High Bay 2: ET-138 checkout and pre-SRB mating ops for STS-135; contingency shelter for a Shuttle stack if both HBs 1 and 3 are unavailable.
High Bay 4: Recently used for receiving, inspection, and initial integration of Ares I-X; will be used in April/May 2011 as temporary storage location for orbiter Discovery and later in 2011 for temporary storage of orbiter Endeavour.

And pre RPSF construction, the SRB pre stacking ops were done in High Bays 2 and 4

Is there any layman's explanation for what LOX drainback is all about, specifically re: the STS-133 launch hold. Thanks!

It's getting more attention; some posts in the last few pages here, and I highlighted Mark Kirkman's primer several posts back:
http://forum.nasaspaceflight.com/index.php?topic=17437.msg709924#msg709924Maybe not a layman's explanation, but I'd still encourage Shuttle geeks to read it.

Thanks Phil, that'll work! I'll boil it down from there.

Has the shuttle ever done a FD4 rendezvous to the ISS?
Yes, on STS-88 (Node 1 installation on the ODS required the extra day).
Interesting. That's kind of a unique scenario though. Was STS-88 the only time?

STS-74 docked to Mir on FD 4 for the same reason involving the Mir Docking Module.

What I'm driving at is this: Was there ever a time when the shuttle launched on a day when both FD3/FD4 rendezvouses were possible, intending to rendezvous on FD3, but for whatever reason rendezvoused on FD4 instead?

Is it possible that NASA could take a picture with all three shuttles together before Discovery leaves? I'd love to see them in a line abreast, in a file in order of seniority, and with their noses together.

I seem to recall that on one Shuttle mission, the Orbiter's drag chute was not deployed on landing, as it had been decided against it, because a cover (or something similar) had fallen off earlier during the mission.
Which mission was this?
Had there also been other missions, where the drag chute was not deployed (on those missions equipped with a chute, of course)?
Has there ever been a failure of the drag chute?

STS-95. I'm not for sure on the other questions. I'm pretty sure there has never been a failure... I'll let the experts weigh in.

As mentioned above it was STS-95. The door fell off during SSME start. There was some analysis and concern that the chute could have been damaged from the various thermal environments and so it was not used.
There aren't any other missions that I can recall where we just didn't use the chute and there have been no failures of the system as a whole (maybe some tears hear and there).

What was the chute's condition post flight?

Thank you!
Is that chute compartment door hinged, or does it usually pop off on a nominal chute deploy?
What was the reason that it fell off?

It's not hinged but fastened. It always comes off on chute deploy a little "cannon ball" ejects out the back and blows it off.
I wasn't involved at all in this at the time (was still very much a "fresh out" working another system) but as I recall it had something to do with the frame.
