At great risk of being fired for not going through proper channels I can tell you that the plan is this: If we have not launched by Wednesday, the lightning protection system will be taken down as protection against FOD. The shuttle weather protection system will be removed and the RSS will be retracted. An MLP has been moved into the VAB but save for a few SRB segments little stacking has been done and 103 is safely in OPF 3 so we can then send techs up onto the VAB roof to retrieve tarps to cover 104. If not enough tarps remain there is a Walmart in Titusville and we will get whatever else we need from there.

Don't you think they will have sold out by that time? :-)

Craig Fink - 27 Aug 2006 19:08 GMT During Hurricane season lots of store will bring in lots of stuff to prepare for it. All the common things, plywood, batteries, water ... I would doubt that blue tarps are plentiful.
But, if it takes two days to get it back in the VAB, I would think Tuesday or sooner would be...

Yep, being serious - if it's not launched by Tuesday night and this storm stays on its forecast track I have to think they'll be taking a serious look at a rollback. Let's keep 'em crossed that we launch on Tuesday...

Actually I just heard they'll decide late tonight about starting to roll back Tuesday. Damn weather.

Let's keep 'em crossed that we launch on Tuesday... You'll be getting outer feeder bands of the storm, or worse, swamping you by Tuesday. I think Monday is the last chance for a rollback.

Let's keep 'em crossed that we launch on Tuesday... Does NASA have fixed metrics on how much wind/rain a shuttle can widthstand at the launch pad ? I know that it has, in the past published specs on what its buildings can survive.
If Ernesto ends up being only a Car I or tropica storm by the time it reaches KSC, does the Shuttle really have to be moved back to the VAB ?
Someone mentioned retracting the RSS. If NASA decides to leave the shuttle at the pad, woudln't the RSS remain over it to protect it ?

If the decision is made *not* to go to rollback prep and to instead go for launch on Tuesday, a see a possible problem.
I recall a lauch once being scrubbed *after* main engine ignition but obviously before SRB ignition. If that were to happen on Tuesday (or something similar that happens late in the countdown that prevents launch), doesn't that mean the system gets stuck at the pad during the arrival of Ernesto because of insufficient time to detank, prep for rollback and rollback?

Improved engines since then make it unlikely nowadays. Most last minute delays in the last decade have been for... wait for it... the weather.

I don't think they'd have time to roll back, last-second launch abort or not, after Tuesday. They either go for launch Tuesday, or roll back Tuesday. Weather will be too bad for either on Wednesday (and I have my doubts about Tuesday's weather, too.)

That lightning strike killed this window. When does the next one open?

Finally found confirmation of this:
"The forecast for Tuesday calls for showers in the area and if NASA failed to get Atlantis off, engineers would not have time to get the shuttle back to the VAB before high winds from Ernesto reached the area."

Heard that NASA would make a decision no later than 07:00am KSC time on Monday.
My guess is that unless the weather outlook for tuesday is *great*, they'll probably play it safe and decide to move the shutle back to VAB.
Even if the weather looks great, they have to look at the possibility of some glitch that forces a scrub at the last minute on Tuesday, and whether at that time, there would be enough time left to bring the shuttle back to VAB (or whether it is save to keep shuttle on the pad during the weather event).
Jim Kingdon - 28 Aug 2006 12:32 GMT > whether it is save to keep shuttle on the pad during the weather event That's the crux of the matter, as I understand it. They were waiting because they thought maybe the storm would weaken or change course.
It has changed course a bit, but in the direction of going *closer* to the Cape: http://spaceflightnow.com/shuttle/sts115/060828rollback/5am.gif
So they have decided to roll back.
Craig Fink - 28 Aug 2006 14:39 GMT >> whether it is save to keep shuttle on the pad during the weather event > [quoted text clipped - 6 lines] > > So they have decided to roll back. If you look at how Ernesto is moving with respect to the model predictions, it's not even close. It's at or outside the range (bounds) of predicted tracks. Not even close to the little black line in the middle of the range.

At the current rate of the groundtrack's eastward migration, it looks like Ernesto will pass the Cape well offshore. They might be able to avoid the rollback.

Contiuning to try to launch is going to cost us another crew......

Latest as of this morning is no launch attempt Tuesday, prep for roll back decision to be made on actual roll back Tuesday.
