You kinda had to expect that yesterday's smoothness was not too likely to be repeated.
Great updates folks, thanks a lot! To summarize, they eventually completed the STIS task (after ripping a stripped socket-head-cap screw head off by force) and didn't get to NOBL, correct?
Correct. Completed STIS, no time for NOBL.

HST rotated to +V3 side forward.

She works a Sun Protect attitude during the EVA to protect the space walkers from the sun.
Yes I know (by the way are there also small changes in orientation of Atlantis hidden under "Sun Protect" phrase?).
Imo I don't get it why shuttle is changing this "-ZLV +YVV" into this "-ZLV -XVV". These orientations are connected with lowerin risk of MMOD impact?

Can anyone here recap on what's completely done, what's not?
In particular, I'm a little hazy on if all three of the ACS are done? Any chance for HRC or is that toast?
I assume there's some pretty touchy current protection so the HRC won't take the WFC that's feeding it out. I'm not sure, but I think they didn't rule out the HRC as being the cause of the side 2 PS failure in the first place. If the glitch is the current limiting kicking in, it wouldn't be good.
So no hope for HRC because it is the proximate cause, and we've no plan for repair.
Does that mean it needs to be isolated to keep from killing WFC?
Thanks

Oops, HST is in -V3 side FWD. Will rotate to +V3 FWD.

I've been amazed how much they are getting out of these EVA's. Messing with a cranky old satellite like this is impossible work.

So is NOBL on the cards for tomorrow?

One NOBL is planned. Others will likely depend on how the battery and FGS swaps go on the timeline.

The HRC card bay is separate from the wide field bay - they'd have to have done an identical repair for it as they did for the wide field to guarantee success.
They had some hope that there wasn't a circuit short downstream from the wide field power circuit (going to the original power supply) so the HRC low power circuit could be 'patched in', but it apparently turns out that wasn't the case.
So, yes, the high res camera will be no more.

HST rotated to +V3 side FWD. Visually the insulation on Bays 7 & 8 looks degraded.

Megan says the outer insulation on bays 7 & 8 appears to be pretty torn up.
(first time they've had a view of that area)

Couldn't get a screenshot in time, but Dan Burbank needs a better background image on his PC. He was logging off and I was expecting a nice shuttle picture, not the default green hills picture

Eh, depends on personal preference, really. I have a rather bland blue pattern background and don't bother with pics - it helps to easily see the desktop icons, and since I always have at least one browser window open covering 60% of the screen, and usually others open as well covering much of the rest, there's no sense having a background picture I'll never bother looking at.

The right-hand bay (bay 8 ) was the NOBL replacement originally scheduled for this EVA.

Interesting listening to this little planning meeting for EVA-5 between Tony Ceccacci, Scott Altman, and John Grunsfeld.
Talking about a partial NOBL 8 and full NOBL 5 as baseline, but crew lobbying to be ready to do a full 8 and full 5 if the high priority tasks (batteries, FGS) go ahead of the timeline.
Sounds like they will see where things are tomorrow when they get the FGS task done.
Mission Status Briefing now targeted for 7:30 pm Eastern.

That's a good characterization.
And you're right, it was fascinating listening to the Flight Director. Isn't this the second time he's done that on this mission? How often does a Flight Director speak to the crew?
