All documentation going on L2. Round ups and news updates in here.

Hi folks. I'm absolutely amazed at the wealth of incredible information this site offers. I'm nothing more than just a regular, average-joe shuttle fan from saskatchewan, canada (and I think I saw someone else from Saskatchewan on another section of the forums..good stuff :-)). This place makes me wish I'd paid closer attention in my highschool physics/chemistry classes fifteen years ago..HA.
Anyway - regarding the minimum duration, seven day flight timeline. If, on the TPS inspection, they find that the TPS has taken a significant hit, at what point would they do any repairs? Would they extend the P3/P4 truss installation EVA to include any TPS repairs? It seems as though there's only room on the timeline for one EVA (as Wayne Hale alluded to during the news conference yesterday).
I apologize if this has already been dealt with in another thread, but when I read the timeline just now, that question came to mind.
Thanks for creating an incredible place for fans of the space shuttle program :-)
-Ian.

A seven day mission (+ 1 weather ??) would result in a launch window until September 12 or 13, am I right? But this is not enough for a fuel cell swap, is it?

And this was as short as I could make it
http://www.nasaspaceflight.com/content/?cid=4770Includes some of the poll answers on yesterday's decision. We will get all the MMT documents - errr before the MMT gets them
- on L2 over the next few hours.
There's a lot more to add, so I'll update as fast as I can, as we go.

There's no way prelaunch that they're going with an MDM, this flight is too important for that. Maybe if it was STS-121 then just maybe they would do it.

I don't think they would launch into a MDF; if there's some increased risk that the fuel cell would need to be shut down, then they are looking at a MDF.
The time issue on-orbit is docked duration -- they have to undock by Sept. 17th. After they are undocked, they could stay up for weather; however, in a MDF scenario they probably have more strict landing rules (which would tend to minimize weather extensions).
Fuel cell swap at the pad would take a couple of weeks, so yes -- they're out of the daylight launch window if they make that choice.

Welcome to the site, Ian
Here's a scan of one image from the Sept, 24 Launch Window Document (on L2)

Just a quick comment...my 8-year old has gone overboard on his interest now thanks to this site and NASA-TV on DirecTV...he asked his teacher to be able to watch the launch during class, and has a list of the website he can do so on the classroom computers since NASA-TV is not available on the local cable system. Thanks Chris, esp. for L2...best money I've spent in the last 6-months.
Now a question: The most interesting thing the Go/No Go discussions from yesterday is the (I'm percieving this probably) acknowledgement that outside criticism will come from a GO decision. Is this climate a realtively new opinion inside the Agency (post-Columbia) or is this just me seeing in print/etc. for the first time?

It's probably more obvious since the decision to fly the existing ET ice-frost ramps as-is. I would imagine that upper management is aware of outside criticism, but it's not a good decision making input (which I think they're also acutely aware of).

Thanks, that's very nice of you to say. I can't answer that question as they shouldn't be criticised for any decision, they are doing their homework!

20 more documents/presentations to today's MMT on L2. Some are fascinating, especially the e-mail from Tim North saying "no go".
Also, 10 new images of the Fuel Cell in questions (some likely taken last night).

Update:
L-1 Wx Brief (----)
Weather looks good for tomorrow. 30% chance of weather prohibiting launch. Northrop is still wet, but should dry out if the rain stops.
There was mention of the potential for a Saturday attempt. Not clear what/who has to give in order to get that extra attempt.

Obviously we can't see the L2 content here, but can you provide context? Who does Tim North represent?

Who does Tim North represent?
The EGIL officer on console for the STS-93 ascent. Could be influential. Might make an article out of this anyway.
It's a very long e-mail (absolutely brilliant if you're into engineering).
Ends with this:
"Given the failure we've already experienced, I don't think you can draw any strong or definite conclusions that fuel cell 1 coolant pump will not experience an additional winding failure. So, I think you essentially drop back to the discussion from the MMT regarding whether you want to go into a flight with the distinct possibility that FC1 may not support an entire mission."

Is Tim North on the engineering team?
