Does anyone know who the female PAO is that sort of sounds like a southern cheerleader? She covered the mission after the -127 launch, and mentioned the ISS being "200 ft above the ocean" so I was curious who she was. For that matter any of the PAO's aside from Mr. Diller. Thanks.

Let's hope it's more than 200 ft above the ocean!

Are these explosive bolts attached from inside the shuttle? If so, how do they gain access to this area?
No, the bolts are accessible from the outside

The STS-127 crew has a sleep shift of 2.5 hours so far (12.03 GMT on FD2, 9.33 GMT on FD9). Is this normal, or does STS-127 have any special reason to sleep shift a lot?

In the STS-127 FD 09 execute package at
http://www.nasa.gov/pdf/372278main_fd09_exec_pkg.pdfon page 17 of pdf (or 3-97), there is an entry at 22:00 MET titled
"LOW BACK PAIN QUEST (ASSY OPS, PAYLOADS)". also found on pg 16, at ~22:50
is that real, or is that supposed to be a gag? what is it referring to?

Real. Due to the lack of gravity, the disks in the spine expand and the astronaut grows a couple of inches. This expansion puts some strain on some back muscles and cause pain. The questionnaire is part of a study into alleviating the pain.

looking at old landing video (sts-2, 41-d, etc, etc)....why does the shuttle appear to no longer use the RCS above mach 1. it always left contrails in the sky as quick puffs of white smoke.....i never see them anymore....has something changed?
thanks!

what was the reason for changing the color of the little "flapper doors" over the elevon hinge line from black to white? was this a thermal issue?

I believe those were OMS pulses and I further believe it was used to help the T-38's visually acquire the shuttle.
They weren't OMS and they weren't to help the T-38.
They were yaw thrusters. As far as not seeing them now days is just a coincidence, atmospheric conditions weren't conducive for seeing the pulses.

Figured I'd post this here rather than in the processing thread but few questions on the pull tests for the ET (not there isn't an ET QnA that I missed right?)
How often are the pull tests done?
With so many being done, couldn't that pose a hazard risk of some type, such as failure of the foam in the area, no resealing properly, etc? (sorry, messing with the ET brings lots of safety questions to my mind)
And what is the difference between NCFl foam and the BX manual spray? Does the spray work just as well as the foam?
Sorry if this is in the wrong area...
Sarah.

Thanks for the answers to my earlier questions. I do have a couple of others.
How are the liquid hydrogen and oxygen generated for the shuttle?
How are the gases generated and then subsequently cooled to cryogenic temperatures?
Are they generated on site or transported in?

There is a liquid Oxygen plant in nearby Mims FL. It is trucked from there to the pad. The LH2 is produced from methane in a plant in Louisana.
I would google to get the answers on the production processes.
