Thanks for the kind words, though we have the best sources and credit goes to them.

I hope it is not the 7th. I liked the idea of the 2nd a lot more.
It won't be the 2nd. Hale already made that clear.

Is there a launch window chart for the entire January window? All I've seen so far is the 5:45 am time for 1/2 (Bill Harwood and some areas on this forum) and the one chart going up to the 7th on L2.

I have calculated the launch time for a 7th launch to be approx. 3:50 am EST.
Here's my launch window list:
Jan 2: 5:45 am EST
Jan 3: 5:22 am EST
Jan 4: 4:59 am EST
Jan 5: 4:36 am EST
Jan 6: 4:13 am EST
Jan 7: 3:50 am EST

"Regarding the LH2 feedthrough area, I liked the theory proposed by someone here that perhaps in addition to the cryo environment, it had something to do with the mass loading of the tank. That is, as the tank gets loaded with tons of fuel, the structure deforms in a way (unnoticed until ... next Tuesday!) that is causing those connectors to lose contact. On one hand it doesn't make sense because the tank isn't hanging off the shuttle, it's the opposite, so the mass loading of the tank should have no effect on that interface, but perhaps it does strain the tank structure between the shuttle attachment points in a way that causes a strain / disconnect at that feedthrough. Anyway, that was the most interesting theory I've heard so far."
OK to add my two-penneth worth:
If the ECO connection could become open circuit when the ET is loaded, then when the ET is depleted (like before MECO) couldn't the connection close again?
I dream for the time and money for L2

Will Jan 10 still be ok for STS-123?

Good move by Wayne Hale to move the date. There's a lot of tired people working 122.

Hopefully it will be January 10, but whenever it will be, it is still a spectacular thing to watch. Lucky to be able to see a little bit of it from our backyard on clear days (we live on the West Coast of Florida).

From L2 information, including a key presentation, dated today:
STS-122: Troubleshooting begins at pad - NASA identify fault candidate
http://www.nasaspaceflight.com/content/?cid=5309
Very impressed by the work the engineers aer putting in on this fault tree. Thanks for the excellent write up.

I guess a Jan. 10 launch date still won't impact STS-123? The only thing I can think of that will have to be done quickly is the pad turnaround. Wise move moving the launch date, in my opinion. The team deserves some time off during the holidays after the phenomenal work they've done this year.

Couldn't they use the other pad for STS-123?

Looks like the next beta angle cutout wouldn't be until early/mid May.

Probably not, given the renovation and Constellation work being done there right now:
http://www.nasaspaceflight.com/content/?cid=5042The requirement was to support LON for STS-125 (some of the caveats are noted in the article above), which likely won't be needed until early summer.
