They can't retract the Array.
Did they say why they can't retract? Can't watch or listen right now, but I was afraid this was the case...

It is thought that the guide wire is snagged on a grommet which has broken free from the first tear area and is starting to damage the second fold where the smaller rip is. The grommet could be snagged on a wire fray. They are not happy with the present config and moving the array in either direction could make matters worse.

Mobile Transporter from site 8 to site 3. OBSS out of Discovery, back to site 8 with the boom.

I presume unbearthing via SSRMS, handoff to SRMS for MT translation, then handback to SSRMS. Not sure the loaded SSRMS could do the translation.

No, they specifically stated the translation would be while still grappled to the OBSS.

Yeah, grapple, move with OBSS, to worksite. So the first move is getting the MT to Discovery, pick up the OBBS, head back out.

Won't the loads induced by the OBSS be likely to damage the SSRMS as well?

Probably depends on what the arm and OBSS positions would be before starting MT translation.

Just listening to the replay of the status briefing and per STS-122 preps, I parse Mike Suffredini a little differently: he said that they are asking the shuttle program to preserve the 6 December launch date -- meaning continue the hardware processing and mission training that's mostly independent of the ISS preparations. So the shuttle program will probably be ready by early December, but it's the stage work on-orbit that is critical path.

Another detail from the briefing on the changes to the 10A stage -- with the PMA-2 prep EVA back in the stage, they will sleep shift ahead of that, which probably also changes the time of day for the subsequent robotics...

it is much lighter than P6

Loads are not a problem. Dynamics when crew is on the OBSS will likely require careful control of movement. We have been runnings sims

Remember all the swaying when they were running the TPS repair simulation? Do not want something like that near high voltage or least want it fully under control. Probably one of the reasons only one crewman on the arm.

Thanks for the note. Please check your PMs.

Hmm, interesting from Bill Harwood...I'm assuming this would be descending node entry and landing:

Quote

In yet another major change for mission planners - and the Discovery astronauts - the Mission Management Team today approved a revised landing strategy that would move re-entry next week from before dawn to the afternoon. The change will require the astronauts to adjust their sleep cycles and fly a trajectory that will carry them over the heartland of America, a northwest-to-southeast flight path NASA has avoided since the 2003 Columbia disaster. The change will permit additional landing opportunities.

(Apologies if I missed this from earlier...)

Is this the SSPF S6, or an engineering/spares unit?

Do you mean the one that is in the SSPF right now? Then that is the real S6 undergoing preflight processing. All the elements in the SSPF is real space hardware, no mock-ups.

I apologize if this has been covered, but I don't see it here. Where are these "cufflinks" being obtained, and what was their originally intended purpose?

Yes, but in the images you can note that 1) the BGA is by itself on a stand, 2) there is only one blanket box attached, and 3) the overhead crane track and crane itself in the upper background are yellow (which means it's not in the SSPF), so unless they removed one of the S6 BGA/Blanket box assemblies and moved it to a new location then disassembled and opened it, it has to be an additional assembly.

They're being made on-orbit from parts and pieces of things currently available, and are a fix idea only thought of (including their parts and construction) within the last 36 hours or so.

The array pictured is in the Space Vehicle Mockup Facility, Building 9, at Johnson Space Center. It is used for training.
