LIVE: Expedition 35 US Spacewalk (EVA-21) - May 11, 2013

[Avron]

I don't recall ever seeing an image of a MMT meeting before that photo gallery.

now thats managed... your tax dollars or euros hard at work..

Some images of the EVA preparation now up in the ISS gallery:

Looks like Russia reps were absent, or perhaps were via phone only, or had stepped out when pic as taken.

[jcm]

So just to clarify for myself, we have a total of 11 PFCS on board:

2 on P6 IEA (2B and 4B), 2 on P4 IEA (2A and 4A), 2 on S6 IEA (1B and 3B), 2 on S4 IEA (1A and 3A)
2 spare on P6 Long Spacer, 1 spare on ESP-1.

Is that correct?
Do we have any ID or serial numbers for the spares?

I missed the beginning of the live broadcast, but the start in the clip is choppy -- was that as broadcast?

thanks

video has been replaced

Thanks -- appreciate your continuing work to make these available.

You are correct on the number, but I don't have any serial numbers.

...and I see a new slide

Will there be any inspection of the failed Progress KURS antenna while they're out there? Visual confirmation of position/clearances from a distance? It'd give them something "useful" to do while waiting for ammonia bake-out at the end of the EVA (though, I'm sure they won't mind floating around and looking at the Earth).

I'm not sure if there's a clear translation path from P6... and the last line of the second paragraph here: http://research.jsc.nasa.gov/BiennialResearchReport/2009/TEA-6.pdf seems to also add weight to concern.

Also, will they be setting up any cameras to monitor the PFCS? Given that Loop B has had this problem for a fairly long time... A different view of ISS would be cool too

No; if that's necessary, it would be done from the Russian segment on a separate EVA.

No.

JSC says everything was approved.

The Russian management always call in to the IMMT from Russia via phone.  Unless they happen to be in town for some other reason, which is not the case right now.

I was reading Pete Harding's great article about tomorrow's spacewalk, and one item he wrote prompted me to ask a layperson's question...

The spare PFCS's on station have been up there (and outside) for roughly 12 years.  How high is NASA's confidence that the replacement PFCS will work fine after being so long in space in storage?  Why so?

Thanks!

That confuses me. I thought we're "partners"... if it is not a lot of trouble why wouldn't we just go look? Maybe it's not a perfect look[1] but it's better than nothing...

I was wondering that too.
PS this MTU grad loves your avatar

1 - less familiarity? But are the Russian cosmonauts that familiar with the equipment? Everyone can speak Cyrillic I would think,

I wouldn't assume that it wouldn't be a lot of trouble.  What are you basing that assumption on?

No basis. How far away is it from P6 (in minutes of translation time or whatever)?

houston cleared for airlock video--will it show on the ISS feed?

Depends what downlink they are using for the video, normally downlink 1 is used on the live iss stream.
