Anyone having dreams about LH2 Feed-through connectors yet?

No, but dreaming she'll fly on the 7th.
Great article, as always. -

Thanks.
One last thing to get out of the way is the inspections to Atlantis' Radiator hoses. If that's ok, then that's her pretty much sorted.
Or specifically, as per L2: "They are also doing a check of the radiator flex hoses that carry the coolant from the system to the radiators."

They have posted in KSC's Media Gallery some images showing how the connector area is looking, now that the foam has been reapplied. Much clearer area, though it's quite small so I think it won't be too noticeable.
(Future reference to all, attach images, otherwise you mess up the format - James).

Into the final cure (18 hours) so right on track for Friday completion. Work already starting on launch configuration.

Chris, any word yet on when activity really picks up for launch? Astro's flying in, countdown start, cryo load etc?
I know probably getting ahead of myself. But with all the activity going on I won't be comfortable that Feb 7th is a real launch date until the tank is loaded. -

DaveS posted a prelim TV schedule last week -- a few pages back in this thread:

Other prelim schedules are around, as on Bill Harwood's site (link), extrapolating from the timelines during the first countdown in December. As long as things continue to track well, they'll set a launch date next week and start the countdown.
Splitting hairs, but tanking to me signifies they'll make a launch attempt and that's well after setting a date and well after starting the countdown. (And even after tanking is completed, there's a lot of things that have to happen correctly to get to liftoff.)

As per L2:
Root cause found for ET-125's ECO sensor system anomalies.
Kryrox grease contamination (electrical insulator at cryo temps). Will write it up.
Consideration of Feb 6 as launch date (but looks like Feb 7 still). Holding that part of the documentation until after the FRR. Very solid for launch now.
Massive LCC discussion at the PRCB yesterday (about eight presentations).
http://www.nasaspaceflight.com/content/?cid=5340 (Summary. Would have been about 20,000 words if I'd of used all of the content
)
Another article will follow from the FRR (which we'll cover live in L2). -

Thanks for all the coverage. Been really interesting to follow this troubleshoot. -

Really is a brilliant turnaround of the problem. If you're not on L2, then you really should be. The amount of documentation on this has been amazing, and easy to get a hang of with lots of pictures and images. I'm very proud of this space program from following this.

That's awesome news. Many congratulations to the engineers who have worked on this.

Still going through the FRR documentation on L2, as there's so much of it (they've had to re-write a lot of things due to the delay) but all looks great.
I'll look at writing some of it up for an article tomorrow morning (might need two articles, we'll see).
Couple of weeks and we'll have the Shuttle Surge back on. Three launches over about 10 weeks from that point! -

We'll be back in launch fever!!! Yeah!!!
