Asked on the STS-131 thread, but I'll ask here as well. Is the ATA flying on 131 the same one that returned on 128? Thanks!

Here's a math problem for our rocket scientists in the audience
What would be the performance increase of STS if NASA were to (hypothetically) launch from St. Anthony, Newfoundland (which is at approximately 51.6 degrees North)?
Put a different way, do we benefit from the due east launch to ISS there, or does the slower rotation of the Earth there more than cancel out the benefits of a due-east launch?
For the purposes of this question, you can ignore the usual gotchyas like "it's too cold there!" or "That's in Canada!".

As a first order approximation, the advantage from the due east azimuth and the disadvantage of the lower rotation speed cancel out. They'd cancel out exactly if the Earth were a perfect sphere. In the real world, KSC has a slight advantage due to the Earth's equatorial bulge.
Edit: found my earlier, more detailed answer:

IIRC they sad the tank returned on STS-128 was going to be filled up and flown back up again.

That's what I remember as well, but wanted some confirmation. Thanks!

Can some one explain how the payload canister is installed into the Shuttle's payload Bay?. is the payload removed form the canister at the pad and installed or is the canister being just loaded into the pay load bay?

They move the payloads from the canister to the Payload bay at the launchpad. The canister is just used for transporting the payloads to the launchpad from the processing facility.

Not directly...I think this has been answered in the Q&A threads before, but I'm not finding a specific post at the moment. There was an early thread that outlines things, though:

QUESTION: somebody has drawings of a seat of the commander of the Shuttle. (The front , behind, below views, etc.) Thanks

Your question has been moved to another thread so if this thread gets deleted you know where to look -
http://forum.nasaspaceflight.com/index.php?topic=17437.msg567352#msg567352Someone else on the forum most likely has more information than me, but as far as I know Shuttle seats are a variant of the SR-71 Blackbird's seats.
The one with the lady in it is an actual shuttle seat.

I agree. To would be about the same. The Russian's hurt their performance a bit because they have to launch a little bit north to avoid China, then they come back south to 51.6. I learned this over vodka shots with them in Houston in about 1993, so it must be true

What is the advantage of 3G throttling over shutting down one engine a little earlier?
And we all know the shuttle throttle's to 3G to allow Navy fighter pilots to be able to fly the shuttle

P.S. I used to love to put this dig in my entry overview class to the Navy test pilot school class visiting at JSC. It always generated a belly laugh and a groan.

The original seats installed in Columbia were. The other orbiters never had the original seats; they had lightweight non-ejection seats. In the late 90s the seats were replaced again with even lighter seats for performance enhancement for ISS missions.

Thanks Jorge. The last picture probably shows the newest seat design.

I believe you're right. I think the seat upgrade was completed before MEDS.
