Full mission success when the NOBLs are installed. Absolutely awesome.
The NOBL's were not in the full mission success list were they Chris?
Low rank on the mission priority list I think.

Sorry for the long post, but:
As with every space shuttle flight, NASA has established a set of mission priorities and defined what is required for minimum and full mission success. The priorities, in order, are:
Three Rate Sensor Unit (gyroscope) removal and replacement
Wide Field Camera 3 installed in place of Wide Field Planetary Camera 2
Science Instrument Command & Data Handling System swap out
Cosmic Origins Spectrograph installation
Battery Module replacement installation (Bays 2 and 3)
STIS or ACS repair
Fine Guidance Sensor 2 removal and replacement
Remaining instrument repair (choice will be prioritized based on actual EVA progress)
New Outer Blanket Layer installation (Bays 8, 5 & 7)
Soft Capture Mechanism installation
Reboost Hubble Space Telescope altitude
Minimum Mission Success, i.e., what NASA would focus on if a problem prevents a full-duration mission, is defined as installation of:
Two Rate Sensor Units (four gyroscopes)
Wide Field Camera 3
Science Instrument Command & Data Handling system
Cosmic Origins Spectrograph
Bay 2 & 3 Battery Module replacements (six new batteries)
Full Mission Success is defined as installation of:
Three Rate Sensor Units (five gyroscopes)
Wide Field Camera 3
Science Instrument Command & Data Handling system
Cosmic Origins Spectrograph
Bay 2 & 3 Battery Module replacements (six new batteries)
Space Telescope Imaging Spectrograph repair, or Advanced Camera for Surveys repair
Fine Guidance Sensor 2

Still plenty of work to be done, though. Need to install the NOBL's, need to get the EVAs inside safely, need to get the aperture door open, need a successful HST deploy, and especially need to get the crew back home safely.

Sounds like there's a little wiggle room at the end. Ground says hard time for EVA cleanup to start is MET 23:45. That works out to about 2:47 pm Eastern...don't have the cleanup duration in front of me, but think it's a bit more than 15 minutes...
Correction (off by one) -- MET 23:45 would work out to 1:47 pm Eastern. (Not so much wiggle room, actually...)

Tracking a hard time to head into closeouts, to ensure they get to bed on time. Still enough to complete the NOBLs it would seem.

NOBL 5 is out and ready for installation. Have to write an article, so if we could have some of you updating/screenshoting while the regulars have vanished, it'd be appreciated.

Just checked some times.
MET is currently 22:21 and all three NOBL tasks nominally take 1:10.
Final closeout/ingress is 1:10 in duration (but they start that at 23:45 MET)

Yeah, I screwed up; was off by one (updated earlier post).

Bottom and top wires are cut, they are ready to start peeling.
As they start peeling, they are experiencing some debris.

Looks like we have removal of a big piece of blanket, and a little piece hanging on to the bitter end.
