I've noticed that most landings at KSC lately have been at RWY15. The last one at RWY33 was STS-120. Is 15 favored due to weather?
I know one of the criteria is to not have a huge turn to line up on the runway. Anything over about 300 degrees is frowned on because it become more difficult to fly these large turns for many different reasons.

Actually, main runway selection at KSC is
generally determined (prior to the primary EOM day) by the sun angle relative to the runway. Morning landings will generally favor Runway 33 so the final approach is flown with the sun behind and to the right of the CDR and PLT. In this way, runway 33 would be the prime target with winds and specific weather patterns factoring into the
final decision for which end of the runway to target.
Case in point:
-- STS-114 was targeting RNWY 33 (but diverted to DFRC);
-- STS-121 targeted RNWY 33 until 10 minutes or so before landing when a shower popped up to the south. Discovery's CDR then targeted RNWY 15.
-- STS-115 targeted and landed on RNWY 33 just before dawn in September 2006.
-- STS-120 targeted and landed on RNWY 33 in the early afternoon (with head and tail winds making the the final decision for MCC to stick with the RNWY). Energy management of the vehicle was also a consideration in the initial selection of the RNWY 33 for this mission.
-- STS-122 initially targeted RNWY 33 for a morning landing but -- before the deorbit burn -- MMC switched to RNWY 15 at the discretion of the Steve Lindsey in the STA.

what was the white plume coming out of Discovery's wings shortly before touchdown??

Won an auction for a piece of the shuttle and was wondering if someone could fill me in on what the numbers mean.
Tag reads TCS 2-27-2682, I know it belonged to Columbia but what was the purpose. What do the V070 numbers mean, catalog numbers I would assume? It's a TCS Strap, has 6 snaps on it. Will post a picture if someone needs.
Sorry if this is in the wrong spot, thanks.

Drawing number, which with the dash number ends up being the part number.
V070 means it is a Rockwell drawing

Hello!
I really want to have a transcript of a man who comments on nasatv whether it goes for take-off or landing. Is this possible to get, if it is, where?
Thanks for your help

@fcmadrid: I do not know exactly how you would get this, but if you go to
http://www.nasa.gov/about/contact/index.html I bet you could get the phone number and/or e-mail address of an Office that would get you to the right person or whatever :-) On the right side of webpage is a frame called 'Contact NASA' - I would start there myself...
HTH, and good luck,
ALex

I saw some replays of 128's
liftoff and you could see tip vortices during the roll just above the pad.

I realize that 'research' would likely give me this info, but isn't the airspeed (over wings) as Shuttle clears tower and 'rolls just above pad' approximately same as landing airspeed of which C5C6 asks above?
Thanks,
Alex

A question on the filament wound casing SRBs intended for polar flight from SLC-6 at Vandenberg AFB:
I have managed to find one black&white image of the FWC SRM segments stacked together, and it seems like they only have field joints where each segment is stacked with the previous segment but no factory joints like on the steel segments.
Is this correct? Was this a weight-saving feature of the FWC SRM segments along with the case material change? Also, was the ET Attachment Ring built into the aft SRM segment like it was on to be the ASRM?

Thanks for the answers. On the ETAR: Was it a 270° ring like on the standard steel segments or was it a full 360° ring that would be used after the STS-51L accident?

Quick question, sorry if this is the wrong thread but upon shuttles retirement, for which ever shuttle goes out west (IF it happens) why land the orbiter at KSC instead of just landing at EDW and keep it there?
I realize that the OPF is only in KSC but I'm trying to think outside of the box here. What all is going to go into preping the shuttle for displays, would any of it be able to be done out at EDW?

No, OPF is required for down loading all the hazardous commodities and passivating all the hazardous systems.

Just do what we do at the chemical plants down here in Houston, wait until the middle of the night, dig a big hole, drain the nasty stuff in the hole, then cover it up
If anyone asks, you have no idea why the fish in a local pond now have 3 eyes.

What do the Square root symbols (that are shown before many of the steps in the crew checklists) actually mean?
For example, this is from the ascent checklist:
√ ADI (two) – LVLH
√ H → +400 (θmax = 75°)
AT FINE COUNT:
√ Pitch Dn to α = -2°
√ MECO, ET SEP
√ Pitch Up
√ MM602
Go to RTLS ---MECO--- (FB)

It has been a while, but I think a key to a checkmark is there should be no action at this step. But if something is not correct, maybe an action is needed.
No check mark means an action (i.e. a switch throw) is needed at the step. Maybe someone with more active brain cells and closer to training can confirm.

That's correct. The check step gives the *expected* config and if the config is as expected, no action.
