Latest is that the leak checks went well and the ET LH2 Tank is being repressurized. Fairing and Strut Cover installation in works this morning.

Has the testing at MSFC now confirmed that the connector was the culprit (could they repeat the behaviour?).. or is it still only "the most probable cause"?

Great timing. We're getting the presentations into L2 as we speak, literally right now! Need to read through them and will report back. -

Meanwhile, the Media Gallery has been updated with some images of the feed-through installation (what we saw in the webcams, only in higher-res and over-the-shoulder) and wire splicing results. The whole process can be seen in them, I only attach a few to illustrate:

Looks like very good news. Over the weekend, on LH2 runs, they had circuit instability on LH2 ECOs 2 and 4.
Will write it up as this looks hopeful that it IS the external connector at fault. -

Thanks for the article Chris.
Just like the STS-117 tank repair, this is NASA showing off how good it is at solving a problem and fixing it to ensure maximum safety for vehicle & crew.
February 7 here we come! -

I had to laugh today. The Jan. 7 Aviation Week & Space Technology has a letter to the editor condemning NASA for not having enough sensors.
"Give me a break. Put more sensors in the tank if that's what it takes to stop sensor-related scrubs. Sounds to me like it's time to break out Cost-Benefit Analysis 101."
Sounds to me like it's time to let NASA do their job. They're pretty good at it! -

There's so many things wrong with that letter to the editor, but thankfully it doesn't need explaining to this site's readership as to why. -

That's great news about the test results. Imagine if they had found it was the internal connector, then we'd be in a mess.

I would like to know what kind of seal is used to avoid any LH2 leak.
Are they round shape metallic one's ? in copper ? Are they put in the two round grooves ?
