How did they handle to umbilicals on STS-49? I do remember that, in order to fit in the airlock with the backpacks, two crew members were right-side up while the 3rd was upside down relative to the other two.

Edit: Jim has answered the umbilical question.

IIC, the 3rd EV first went on umbilical and "supercooled" his suit and then went solo when the other two were ready to go on umbilical

Clay's been hilarious on the loop, to a CAPCOM with no sense of humor.

CAPCOM: "Clay for the (something)...."

Clay: "Ah ah ah. I sleep during the day and work during the night.

CAPCOM (Confused) "copy that."

Not ENTIRELY true, CAPCOM called up with "Houston for the COUNT..."... instead of saying "Clay"...

Clay: "Good Eeevening, hah, hah, hah... I am able to do that, because I sleep during the day and I work at night!"...

I'm going to miss Clay...

Just getting back from lunch and not seeing MSB on Media Channel - any news on a change?

Delay of 5 minutes or so.

Think outside the box - you have a Shuttle and a ISS Air lock - Stage the EVA from both airlocks - that could put 4 EVA outside 2 working SARJ 2 working SAW. If I remember correctly, it requires closing hatches between the shuttle/ISS but they certainly did a bunch of EVAs from the Shuttle prior to QUEST. Lots going on - but about as far apart from each other as possible on the complex. I don't know about radio freqs for communication and everyone left inside would be needed to keep track of what's going on - but it would allow you to collapse the timeline a bit. I imagine it would give the ground guys fits trying to keep track of and choreograph it - but if you are starting to impact your downstream work more then more creative solutions may be required.

The only shuttle airlock would be the ODS, which is currently docked to the ISS.

We have the opening notes from the repair plan on L2 (added an image to the main story on site). Will write up some more into the article.

Meanwhile, great image:

Mike S confirms the second tear, about a third the size of the orginal tear.

Chris Bergin · « **Reply #132 on:** 10/31/2007 05:14 pm »

We believe one of the three guidewires snagged on one of the grommets, which started tearing out the hinge."

"We retracted one bay to relieve some of the stress."

"This is our priority as a program. We need this array. It could gain further damage if we leave it in this configuration."

Chris Bergin · « **Reply #134 on:** 10/31/2007 05:17 pm »

"We have a very high stress point at the tear (the main one). If we damage this array enough, we may not have it for the remainder of the program.

"This is the prority for the remainder of the STS-120 mission.

"We've stood down from the SARJ effort. EVA-4 will be Friday. Today and last night is about plans on repair work."

OK so use the ISS crew from QUEST and use the Discovery crew on Discovery - EVA 5 will be just the ISS crew anyway.... This is about thinking what can work and finding a way to make it work - not about why it won't work and then dismissing an idea.

"We've got a lot of great ideas (for the repair) - creative solutions.

"We feel pretty good about getting out for an EVA-4 on Friday.

"If we have the proceedures in place tonight, we will formally ask the crew to go ahead on Friday.

"Friday is best, as we may need another opportunity to go out and look at it.

"If it's successful on EVA-4, we will standdown and let Shuttle go home.

"If EVA-4 is not successful, which is a possibility, we would like to have the option to persue EVA-5 on Sunday. We would have to delay departure of Discovery by another day."

"Clear the snag. Add some load bearing (somethings? help please) and try and do this on Friday."

"I just came back from Building 9. We're looking like we have a chance to use the boom without retracting the array. We look like we'll have a way to cut the snag.

"We could insert some wire into exsisting holes. Blanket restraint system for the ride to orbit. So we have a reinfornced strip we could transfer to load to, instead of the hinges."
