MEDIA ADVISORY M13-123
NASA Television to Broadcast Two Russian Spacewalks in August
NASA Television will provide live coverage as two Russian cosmonauts venture outside the International Space Station on spacewalks Friday, Aug. 16, and Thursday, Aug. 22.
NASA TV coverage will begin at 10 a.m. EDT both days.
Flight Engineers Fyodor Yurchikhin and Alexander Misurkin will install equipment for the arrival of a new Russian module and begin preparations for the installation later this year of an optical telescope.
The two cosmonauts will exit the Pirs airlock at about 10:40 a.m. on Aug. 16 for a spacewalk scheduled to last about 6.5 hours. They plan to continue routing power and Ethernet cables for the future arrival of the Russian Multipurpose Laboratory Module, which will be launched aboard a Proton rocket from the Baikonur Cosmodrome in Kazakhstan. They also will install on the Poisk module a panel of experiments designed to collect data on the effects of the microgravity environment in low-Earth orbit..
The spacewalks will be the 172nd and 173rd in support of space station assembly and maintenance, the seventh and eighth of Yurchikhin’s career and the second and third for Misurkin. Yurchikhin will wear a Russian Orlan suit bearing red stripes, and Misurkin will wear a suit with blue stripes. Misurkin’s suit also will be equipped with a U.S. helmet camera to provide close up views of the work he will be performing outside the station.

Russian EVA 34
Published on Aug 13, 2013
EVA Specialist Devan Bolch discusses Russian EVA 34 and Flight Engineers Fyodor Yurchikhin and Alexander Misurkin who will begin Friday's spacewalk at 10:40 a.m. EDT.
Their first task once they exit the Pirs docking compartment will be to deploy the Strela boom which is a portable, telescoping crane that can move gear and a spacewalker outside the station. They will use Strela to install connector panels and gap spanners outside the Zarya and Poisk modules.
Yurchikhin and Misurkin will also install the Vinoslivost experiment panel on Poisk which exposes different materials to the space environment. After that they will route and secure power and Ethernet cables outside Zarya and Poisk. Before reentering the space station and if time allows, the duo will stow the Strela boom.

Really going to need all your help covering this one folks. I might just get time to write the article, but day job is in the way most of the day.
I'll think up special bonus prizes for those who provide more than one hour of coverage.

The EVA starts in a little over an hour.
Somebody please check if these notes are correct:
- UECC - Universal EVA Cable Carrier - carries the power cables that will be routed.
- СЭС-1 and СЭС-2 - connector pannels where the cosmonauts will connect the power cables.
- The ethernet cable won't be connected anywhere, just stowed on FGB GA (the docking adapter that connects to PMA-1)
-
12 minutes into pre-breathe; 18 minutes left. Luca assisting with EVA prep.
-
Leak checks successfully completed. The airlock hatch is tightly sealed.
-
Alright, it's on! Coverage starting in a couple minutes.
-
NASA TV coverage started now.
-
-
-
Rob Navias is providing the commentary.
Pavel and Chris will spend the day in MRM2 and their soyuz. Luca and Karen are free to move around the USOS.
Fyodor will wear a suit with RED stripes
Sasha will wear BLUE stripes

Russians cracking jokes again :)
"Why wasn't I blessed with a longer arm?"

Stop motion, start retracting (that's what the interpreter says, I think they're doing the opposite)
edit: confirmed, extending Strela

Looking at the timeline posted here earlier, it appears they are over 30 minutes ahead of the timeline.
Going into darkness in a few minutes
-
Up next:
securing the Strela in a cradle on the FGB. Retraction of the arm back to Poisk is planned as a get-ahead.
-
Gap spanner to be installed:
-
Sasha now working on installing the Vinoslivost experiment; then gap spanners from Poisk to Zvezda and Zarya.
-
Looks like the material experiment panel has already been installed?

Fyodor is working on routing the first power cable, unfortunately he doesn't wear a helmet camera.
Meanwhile, Sasha is preparing to install the connector pannel number 1

I don't understand why they retarct the GStM (what the US call a "Strela crane") after each EVA ? During Mir, they let the GSt (the predecessor of GStM) in position, this way they didn't had to deploy it during the next EVA...
-
They're taking some rest.
.. And I'm going to get some dinner - back in 15 minutes.
-
The Spacewalkers were instructed to take a 5-minute break :).
-
Aleksandr Misurkin installs a gap spanner between Poisk and Zarya.

Sterling work so far guys! Amazing how useful these live threads are when you pop back in and catch up with the pages,

Actually, they don't retract it fully. Before this EVA, the end of the boom was stowed on Pirs, while the base is on Poisk. I don't think they're going to need it extended this far forward in the future EVAs, thus the get-ahead to retract it.

2 hours into the EVA!

You guys are doing a fabulous job, many thanks.
Can only get a few minutes in through work server with flash stream
-
Alright, I'm lost. Which task are we at? Sasha is translating down the boom to meet up with Fyodor but why? I thought Fyodor was suppposed to route the power cable himself. Also, the Strela doesn't look to be secured in the cradle - it's moving around too much. Can anyone enlighten me?
-
Meanwhile, a nice view down the Strela

Sasha is routing the power cable via fairleads while Fyodor is unwinding it from the carrier.
-
Thanks guys. Not much happening right now - no KU for some time. I think they're still working on routing the power cable.
-
Half way through the first cable routing - on handrail 1310
-
The first cable has been routed, now they're working to wire tie the cable to some handrails and plug it in the connector pannel number 1.
-
45 minutes ahead of the timeline
"I thought we were behind." - So that's why they're working so fast! :)

-
The cosmonauts are worried that they're slowly losing the FGB as a translation path with all these cables flailing around.
-
So, the power cable is connected to СЭС-1, now wiretying the rest of the cable.
-
Ready to take the ethernet cable.
And I'd like to point out that Rob Navias said the ethernet cable is wound on the universal cable holder, while the cable is in fact on its own reel, shown in the second picture.
-
-
Working together with ethernet cable reel
-
20 minutes or so to sunset. I know that because they're passing over me in 15 minutes :D
-
Waving at Pavel Vinogradov inside the MRM2. You can see his face through the reflection.
-
The views right now over the side of Poisk and Zarya are unreal.
-
More Cable please...

-
Unusual view of the truss
-
Cables, cables and more cables.
-
Still ahead of timeline.
-
Not much Ku at the moment.
-
Late to the party, thanks everyone for the coverage
I assume they are using the same suits as last time? (Yurchikin MK No. 5,
Misurkin MK No. 6)
-
Still routing the power cable. Tedious work when you have to take care of your tethers.
-
-
Now securing the cable.
-
Fyodor will take some photos while hes waiting for Sasha to finish with a cable fairlead.
-
"And there are no Singapore Airlines flight attendants here" HA!!
-
Going over the tip of Florida it would seem.
-

-
Spacewalkers taking a short break.
-
Sorry, couldn't resist

Back to work.
London pass coming up.....too far south for me I think.
-
Shows how hard it is to get that connector in.....over London.
-
WOW! ISS pass right over head!!
Too much light pollution to get a photo, but that was a very bright pass over York, Northern England!
-
Sasha (?) complaining that 10 min rest is too much, he'll get cold. "All right, 5 minutes"
-

Got to say, that was pretty emotional. Don't get to see many passes. That was only my third pass. Brightest yet.
-
Sounds like they are wrapping up.
Going to rest and then assess, but the likely call is to return to Pirs.

Know how you feel, had the same feelings when the HTV passed over.
-
Discussing EVA extension! Today's get-ahead is retracting Strela back to Pirs.
-
Now eaten up the time they had saved.
-
Ah! We have Sasha at Strela operator post.
-
Talking about using the MUT - obviously a USOS tool - anyone know what that is?
-
-
Anyone know if we have another pass over England coming on this next rev?

EVA start time now revision to 26 minutes part the hour (three mins earlier).
7 hrs 10 mins. Six mins to longest ever Russian EVA.
-
PAO described the Jul 1990 EVA (previous Orlan record) as repairing insulation on Mir's exterior. It was actually insulation blankets that were flapping loose on the Soyuz TM-9 reentry vehicle.
-
Out of Ku as they break the record.
-
The overall record was March 11, 2001 - STS-102 - Jim Voss and Susan Helms 8 hrs 56 mins, per Rob.
-
Out of Ku as they break the record.
Not just Ku but S-band as well. S-band is what is used when the Ku band antenna is unable to lock on to a TDRS. S-band is omni-directional so it doesn't have to track a TDRS with a narrow beam like the Ku band antennas have to. This is why S-band coverage is greater than Ku band coverage.

Because of NASA rule: from battery power to repress.

Still not good if your suit springs a leak - and Ed White was on umbilical throughout his EVA, you're not going to count that?

Thanks everyone for the great coverage - this thread is a lifesaver for people like me who weren't able to follow it live, but still want to get the play-by-play coverage without having to watch through a 7.5 hour YouTube video. :)

I couldn'nt find any notice of any opportunity to drop an antenna cover, as was observed drifting outside two days later. Was there a cause-and-effect with the EVA or a coincidence, do you think?

Well considering the cover had close to zero momentum (as it was just hanging around), one would think that something just gave way, as an inadvertent knock would send it flying away in a relative hurry.

Even more important, the differential drag would have quickly instilled a separation rate even with zero relative motion. So I agree the object was seen very soon after it separated.
Moving in an aft direction is precisely the vector you'd expect early on. But very soon afterwards, not more than an hour or two, it would appear to drop, pick up forward speed, and pass beneath and out ahead of the station.
Now, WHY was it spotted? The crew doesn't regularly scan the skies, who was at the window, doing what?
