SE&I, NESC, KSC and JSC engineers all want rollback and a tank swap.
So then it's QUITE safe to say that will be the scenario, unless they're overrulled by the 'suits'. :frown:

Hard to say, as the likes of SE&I, NESC and JSC Engineering are the usual suspects in "being different" but KSC "Engineers" and JSC "Engineers" - thus we could be talking about many depts. makes this a bit more solid.
I doubt anything will be decided today as they are speaking about coming back to this on Jan 3.

The way it's looking right now (can change).
TPS removed, access to external connector - done.
Remove external plug and connector, send off to MSFC for testing.
See what comes back on the test results, compare with tanking test and ET-120's connector (which was tested).
PRCB on Jan 3 to decide on which option to take (R&R at the pad, or Rollback and swap tanks).

Is the internal part of the wiring and of the connector definitely considered to be in good condition ?

In America we're going through a holiday time, so by default that slows things down... I wouldn't call deciding in a few days to be "paralysis"

... and without analysis, we wouldn't launch at all. We'd never been able to develop the necessary technology...

That'll be inspected (and documented) as soon as the pass-through is ready to be removed.
Reading all the documentation involved, IMO if they want to preclude the internal-to-passthrough pin connections from being a problem, they're going to have to 'go the extra mile' to ensure the pin connections with the internal connector have no "contaminations" at all (physical, or gasses remaining that could freeze at LH2 temps) during the connection and sealing of the internal connector with the new pass-through. And without internal tank access, that's an additional big challenge to be assured and confident of no failures during cryo temps from fueling until MECO.

Wayne Hale's finishing off a teleconference on nasa.gov's audio feed. Basically as we've noted in the latest article (though I've got more to go into there.)

Repair timelines on L2 show best case scenario placing R&R effort to be completed late Jan. So there's a chance STS-122 can launch early Feb at present.

Ok, what we'll do is leave the modified article on site, as that's your basic Option A/Option B overview, but I'll write another based on the presentations that came in later that expanded on the work required and schedules etc....plus this is ongoing, so we'll keep the coverage up and see where they go with this.
As of right now we're looking at the Option A to allow for work to be completed late Jan, which would work towards an early Feb launch. However, they have beaten schedules before, so one to keep an eye on.
Option B (rollback) which shuttle managers don't seem to like, doesn't have a timeline yet.
http://www.nasaspaceflight.com/content/?cid=5319 - modified from earlier with extra info. Not the greatest article, just wanted to get some raw quote content from presentations out there. Next one will be more mapped out.

Good work Chris, more impressed with you getting the PRCB presentations on L2 just as the PRCB sat down!

I have a Question
Can the NASA postpone the launch STS-123 by again postponing the launch of STS-122 ,Can the NASA then as first STS-123 launch and then STS-122?

My understanding is that you're wondering whether or not they can launch STS-123 while they're trying to solve the problems of STS-122. At this point, I suppose it could be possible, but I don't think it's an option they're actively looking at.

Real Madrid, this has been discussed. Please scroll back a couple pages in this thread. In addition to ISS sequencing issues, and VAB stacking resources, they wouldn't want to go with ANY shuttle launch until they knew what the real problem is. It could (probably is) affecting all tanks or shuttles. We're getting close to a resolution, but we're not there yet.

Thank you sir.
Ok, we're up to date. Next event is the external connector coming out of ET-125 at the pad Saturday, ahead of being shipped off to MSFC.
Looking at writing an article around that to keep with the timeline.

Will we get to see anything on the webcams, or will the RSS obstruct the view?
