It will hand the OBSS to the shuttle SRMS today (which will provide power for the OBSS and keep the sensors from freezing). Tomorrow, the SRMS will hand the OBSS back to the SSRMS, which will be at the worksite ready to go!

Hope that helps!

That's clear. What I don't understand is why the SSRMS has to move back and forth again from different worksites and can't just stay in place for tomorrow.

Has to ride along the truss to reach the Shuttle, then go back to the array. Large distance. This has been explained on the previous flight day threads.

I guess the SMRS isn't capable of moving the OBSS to the handover position without running into ISS hardware. During TPS inspections, the SRMS can move the OBSS to nearly any position, but then you don't have to worry about ISS clearances ...

OBSS now with SRMS.

Thanks. I read that but confused me again. That means tomorrow it will have to move again to the Shuttle and again back to the array?

Pambo did her exercise during post sleep. working on EVA prep. She wants to be in on the ROBO conference.

Good job to Pambo on keeping ahead of the timeline!

Thanks Andy, glad someone understands this is a live update thread

If anyone has questions, on the array, most which seem to be previously answered, post them here: http://forum.nasaspaceflight.com/forums/thread-view.asp?tid=10542&start=1 I've moved two recent posts there.

All non update posts will be deleted.

Keep the images coming please. A lot of people can't access NASA TV.

No. The SSRMS will move back out to the array today. It can reach the OBSS from there tomorrow now that the OBSS is unberthed from shuttle.

wrapping up cutters in air lock.

Cutters have a sheath (on station but not in photos) Wondering about the sheath and taping.

Going to show MCC what they are talking about

MCC is going to talk about it and let them know!

I'm trying to get configured to take screen shots but I'm having a bit of a hard time

Here they are working in the airlock. I use the countdown webcam page while trying to config for ss

sounds like they are going to get ready to meet for the robo work conference. Dan is giving kudos to the people that worked on the procedures

I´m sorry, but I do not understand, why the SRMS need the help of the SSRMS and cannot direct put the OBSS.

Andy_Small · « **Reply #36 on:** 11/02/2007 01:19 pm »

PAO reports that robo work is behind on the MCC side

shuttle arm is in Undock position till the work starts tomorrow

Elbow pitch is about 2 degrees off of the norm on the shuttle arm. Pam thinks it's fine but wanted to report it to MCC.

They are go to push on but MCC is looking at the joint angle

The Orbiter arm (SRMS) is too short to reach the Solar Array with the OBSS.
It has to be handed off to the Station Arm (SSRMS).
