Will we get a joint rollout photo-op for STS125 and STS-126?
Hopefully at worst we will see the RSS retraced with the xeon lights illuminated one evening?

Will an Astronaut be able to see city lights when flying over a big city during orbital night when he/she is space walking with an EMU suit?

Certainly feasible, but if done intentionally, it would be out of the norm. The current plan has the HST shuttle on Pad A for a long time before the LON shuttle arrives at Pad B.
I believe the only time there was that type of photo-op style situation was by chance when the STS-41 shuttle rolled out to Pad B after RSS rollback for another STS-35 launch attempt (5 Sept 1990). That was during the "summer of the hydrogen leak" where all three active orbiters got backed up (and in fact that launch attempt was scrubbed for that reason).

yes, just like the crew inside the vehicles

will they also be able to see the stars? As far as I know the ISS itself doesn't have star facing windows.

They can see them from the shuttle

Other way around, Endeavour will roll out to Pad-B first then Atlantis will go to Pad-A

Nope; that was the original plan. They were able to move up the STS-125 launch date by about a month by switching it around (something that became moot a while ago).

Yep, summer of the hydrogen leaks. But there was another photo (which is attached) that was taken during the rollout of Atlantis while Columbia was temporarily stored outside the VAB.
Also, there is currently no planned photo op for this event (and rollout of the two vehicles will be a few days apart), but you never know if that could change with an RSS rollback photo op, though as mentioned above, that would be out of the norm for NASA.

Yes,
already noted. FWIW, it was the other way around; the STS-38 stack was rolling back from Pad A and the STS-35 stack was rolling out from HB-3. HB-2 wasn't a safe haven back then and the STS-41 stack was being built up in HB-1 for the Ulysses planetary window.

hi, I've been trying to find a picture of the recumbent seat used in the shuttle by returning ISS Expedition's astronauts....has anybody got any???

OV-101 did not have a thermal protetion system. It was not needed for the approach and landing test program. The tile pattern was for show.
What about RCC

Fiberglass mockups.
Real RCC is around $800k per panel, no point wasting that on Enterprise.

What is the distance of the ground track of the ISS (assume a 350km altitude) from the time it rises above the horizon to the zenith? I make it about 2060km?

By hand I make it 2065km (assuming a mean earth radius of 6371km).
If my math is right then:
track length = [ pi/2 - asin(r/(r+h)) ] * r
where h = satellite height above earth, r = earth radius, and asin result is expressed in radians.

It might not have been RCC, but it would have been a bit more substantial than fibreglass and also would have had to simulate the rough weightloadings of RCC

Every source and the CAIB states the OV-101 WLE panels was fiberglass.

Yes they were fibreglass. Test results were extrapolated to Columbia's RCC.
In addition RCC from Discovery was used for tests also and I assume, replaced with new/spare. You can spot the new RCC in the STS-114 photos and even now I think.
