Ahh okay, that helps clear it up. Very much appreciated.

Sorry about that Mission Control question popping up here...It got moved by the sys admin for some reason to this thread so it ended up off-topic from my point-of-view. Thank you for the excellent reply, however.

Why does the left SRB have additional stiffeners added to it?
This person's model of both boosters shows the difference.

I've never seen that in photos of actual SRBs. I believe the moldings of that model kit are in error. As far as I know, the only difference between the left and right SRBs, besides things that are symetricly opposite like the BSMs, is the black identification stripe on the forward skirt and frustrum of the left booster.

(Disclaimer -- I know search button is my friend, but couldn't find this topic covered)
At what point in the STS-134 timeline is STS-335 officially stood down? Logic says rescue is unavailable (and thus STS-335 is pointless) as soon as Endeavour is unable to return to ISS.
Thus, two questions:
1) what is the "point of no return to ISS" in Endeavour's post-undocking journey?
2) is there a formal stand-down time for STS-335?

I have always wondered how the orbiter stays attached to the ET during launch. The way the orbiter is oriented during launch has always scared me. How well do they bolt that thing to the external tank?

There is a ball and socket arraignment for the aft attachments

"Arrangement," perhaps? Otherwise what crime are the aft attachments accused of?

Hi folks,
Two questions:
1) Why do they need to "hot fire" the RCS for landing when they just used them for the "fly around?
2) Why is this section of the tank(circled) a different color?

1. The aft RCS is used for entry until around Mach 2
2. That portion of the foam was applied at a different time and therefore had a shorter exposure to UV light.

1. The aft RCS is used for entry until around Mach 2
And the flyaround is flown using the Orbit DAP, which prioritizes the RCS jets in each pod in each direction and only fires the highest priority jets when commanded to fire. The Aerojet DAP potentially uses all of them so we want to know if they're all available; the flyaround is not a good test of this.

I had already asked this question on the STS-134 landing thread, but it was "flooded" and went unnoticed, so I thought I'd repost it here...
During the final minutes before landing, the Shuttle trail is displayed on the screens of Mission Control. There is a solid line, and two red triangles moving in front of the solid line. The triangles are separated by quite a few miles. My question is: which is indicating the Shuttle's position? The first triangle, the second triangle or the beginning of the solid line?
And what do the two triangles represent exactly?
TIA,
Cristian

Hi all.
I quick question for you. I know it's a silly questions, but I need to answer for a project I'm working on.
the questions is: people working in the OPF at the KSC, are NASA personnel or USA contractors?
thanks very much.

Mostly USA and a few other assorted contractors. NASA supplies some engineering.

end of the solid line and the triangles are 30 and 60 second position predictions, I believe. Search the Shuttle Q&A thread, where also, this question should be.

Are there any photo's or illustrations of the sensors orbiters use to take the 'air data' late before landing?

Why was the AFRSI portion changed on the final 3 orbiters? For example you compare Discovery, Endeavour, and Atlantis from when the first flew to today, you notice the amount of AFRSI is less than what was there before. Why?
