It sounded to me like they lost a bolt in the structure.
It was from one launch lock, so there shouldn't be more consequences than other bit of orbital debris out there...

That would be my guess as long as no one comes back and says it could affect the truss in any way. SFN comfirms it was a lost bolt, spring and washer from the launch lock.

An object of that size should be trackable by ground radar. Presumably they will monitor it to ensure it won't recontact the stack at some point later. I have a faint memory of something being lost on a spacewalk before and it being tracked.

Yeah it was Piers Sellers favorite spatula during tile repair technique testing on the final spacewalk for STS-121
I imagine it'll just stay down in the truss structure.

Joe said he was pretty sure it skittered over the cover and went overboard. He looked over and around quite a bit there and in the direction it went and couldn't see it.

Images of the array base with our spacewalking friends kind of puts it in perspective how big this truss structure is. Quite stunning! It's going to be absolutely beautiful once they get those wings deployed. Are there 16 launch locks that have to be removed from the SARJ?

Guess it's a pretty good thing that these things get moving and stay moving in one direction away from the station then huh? Funny thinking that it'll find it's way back to Earth eventually in the form of a charred piece of metal.

Well, they're already verifying they have everything inside the retrieval bag... so the spacewalk is about to end

Hopefully they won't lose anymore lock thermal cover bolts tomorrow.

Correct me if I'm wrong but it seems the SARJ won't be able to allow the arrays to move 360 degrees until 12A.1 retracts the port array on P/6 or the P/4 arrays will come in contact with it. Am I seeing that wrong or did I miss some information completely?

You're right nathan, they need to retract that P6 wing to allow full rotation of the SARJ - I guess they could test it a little though.
I'm wondering whether the lost bolt (if still inboard) could interfere with the working of the SARJ....

Correct. Also until 12A.1 P4 will only have survival power as it won't generate any energy.
This one of the major objectives of 12A.1, to recofigure the station from it's early interim cooling and power generation, to the permanent configuration which uses power from P4 and cooling from S1/P1 trusses.

Solar panels don't have to be exactly facing the sun to still be able to generating power. On Earth they generate power even when it's cloudy.

Heh. Good work today.....some of the calls going up were really complex, as the mission is supposed to be.

Yeah that's what I was beginning to think would happen. I guess they've got it configured to move around a little bit to make sure it works and add some power. I guess that's why 12A.1 is designated a "power reconfig" huh? Haha. Yeah I knew they didn't have to face the sun directly to provide power. And in any case, P/6 is enough to power the station on its own for a good while longer. So these arrays won't make much difference until they start getting more modules hanging off the front of the station. Thanks for the answers!
I imagine it'll just stay down in the truss structure.
