Still waiting for ATVC installation as of this morning KSC time. Getting a bit tight (though I'm not sure how long they need to physically install it). Atlantis is powered up.
If the ATVC cannot be installed by today (My expectation is that the install will go well), I assume efforts continue tomorrow and are we in a day-for-day slip of the NET date, or are there other items in play that push out the NET date?

Would have been, but latest L2 info shows them to be completed by 18:00 local.

Chris can you confirm as of yet if the ATVC has been installed? Thank you so much for keeping us well informed on this issue over the weekend!

We don't have it fully documented yet (which is what I prefer...but the expansive processing documentation runs Monday to Friday). However, we have short notes and references from engineers that it was second shift today.
I've also written up the launch date related article, with some of the quotes from Cathy Koerner's memo:

Thanks Chris for the great updates on these issues. Glad to see NASA is working hard to clear up those inaccurate media reports on the possible launch dates of STS 122!

No problem, though that memo from Cathy was not released to the media. Cathy sent the memo to other flight directors and MOD. Given we've got a load of NASA people on site (L2), we also got hold of it. Think of it as more to do with them clarifying where they stand to themselves.

Two schedules from L2 presentations, now that engineers are just hours away from starting the installation process.
First one is USA. Shows they are on time for Feb 2.
Second schedule from NASA MSFC, shows they are on target for Feb 2 (Or - as you can see here, Feb 7 with a tanking test - decision on that is to come).
They are screenshots from the PDFs, so click the images for larger, readable versions.

Thanks for the update. I was not able to access the thread over the weekend so am glad for the update and to clear up the launch date. I also enjoyed the video of the re-entry and landing. It must really be an experiance being on board and watching the shuttle glow.

And now documented as completed on time with the ATVC.

I'm looking for pics of the repair apparatus onthe pad, as viewed from the usual photo distance. Is there anything visible?

New article coming later tonight. Lots going on ahead of testing proper at MSFC on ET-125's removed hardware, but via the current investigations they've found a new problem with the glass that the pins of the connector are embedded into (cracking has been observed and they are worried LH2 can leak through during ascent = bad, crit 1). They are needing to carry out more testing, and we don't know how bad this could be until then.
Will write it up.

This does not sound good for making a February launch but it is good that they are finding these problems now and can work on a solution to fix them. I look forward to your update Chris.

Don't even hint at eliminating February based on the above... There's no reason to make that leap yet.

Yeah, not to worry. They are confident this isn't going to mess up the forward plan.
Headache of an article to write, but will be within the next hour or so.

Is NASA now paralized in Analysis? Is this good engineering? Planning with no schedule pressure.. no need to deliver.. sounds too good to be true..
Well at least at the end of the program, one would hope that a Dumb drop tank could be made that works.
This is a connector, a basic piece of hardware used on many a tank on many a launch vehicle.. is this a make work project? or a QC problem..?
Maybe zero risk is the only option.. don't fly until the LV is re-certified?

Article on the new issue. Note that it was written without a dramatic "run for the hills" angle, as I really have nothing but admiration for the engineers on this. They could so easily of said "never been a problem before, don't worry about it" but instead they are bending over backwards to cover all the bases. Ironically, that's my retort to some of Avron's post

Someones got to cover the larger angle...
But the questions still remain. (without heading for any hills)
