Quick question, sorry if its been asked before, but POA mentioned on NASA tv last night that Discovery's crew was installing a chair for Kopra so he can adjust to gravity easier on entry. Is this the usual chair you would see on mid-deck or how does it differ?
Thanks.

It's a recumbent seat, so Kopra will be lying down.

Thanks! If I may ask, how is it positioned, doesn't seem to be much room on mid-deck. So he will be laying down with aspect to the shuttle being horizontal, would the head be towards the nose then?
Sorry there for a minute I was picturing a seat laying down while shuttle is vertical. *face palm*

No, feet toward nose.

Here's a link to a picture from STS-79:
http://spaceflight.nasa.gov/history/shuttle-mir/multimedia/sts-79-photos/79p-006.htmFor comparison, I've attached that photo along with a rotated screenshot that Ford posted during strap-in for this mission's launch that shows the typical mid-deck seats in horizontal orientation.

If they're expecting difficulty with afternoon weather in Florida, why not try a descending node landing? Is the boundary layer DTO the reason?

The issue with noctilucent clouds is in the summer (well, northern hemisphere summer).
For a non-contingency case, there's also sleep-shift issues...the descending nodes are closer to crew sleep.

Ascending node or decending node don't really matter when the weather concerns are in and around the 30 nmi circle of KSC. Still violates constraints. Plus a decending node would take the vehicle over the US during the final phase of entry and that is something that is avoided as much as possible post-STS-107.

It's not just afternoon, as we've been mentioning - it's raining about all the time around KSC. Some pretty heavy rain knocking on the door right now even!

Descending node is 12 hours earlier so that's what I was thinking - not the route chosen. But Rob mentioned bad weather in the mornings too, so there goes that idea!

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?

Usually the winds in Florida are blowing from the east (off the water.) I don't know if they sent any other sort of preference ahead of time, but at landing the runway is picked from weather / visibility / STA recommendations.

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.

That is a very complex question with many different answers. First of all, do you mean a launch, or the "price" of an Orbiter.
