MEDIA ADVISORY: M10-159
INTERNATIONAL SPACE STATION SPACEWALK LIVE ON NASA TV MONDAY
HOUSTON -- Two Russian cosmonauts on the International Space Station
will conduct a spacewalk Monday, Nov. 15, to prepare the outpost for
future assembly work. The spacewalk will be broadcast live on NASA
Television beginning at 8 a.m. CST, Nov. 15.
During the six-hour spacewalk, Expedition 25 Flight Engineers Fyodor
Yurchikhin and Oleg Skripochka will work outside the Zvezda service
module. They will clean thermal insulation around the vents for the
Elektron oxygen-generation system, install a work platform, replace
material sciences experiments and move a television camera from one
Russian docking module to another.
Wearing Russian Orlan spacesuits, the duo will exit the Pirs docking
compartment airlock at approximately 8:25 a.m. The spacewalk will be
the fifth for Yurchikhin, who will wear a spacesuit marked with red
stripes, and the first for Skripochka, who will wear a suit with blue
stripes.

Russian Cosmonauts to Have Pre-EVA Dress Rehearsal Today
12.11.2010
ISS-25 flight engineers Fiodor Yurchikhin and Oleg Skripochka will have pre-EVA dress rehearsal today.
The cosmonauts will put on their suits and pressurize them in order to simulate EVA pressure. With their suits on, Yurchikhin and Skripochka will ‘walk’ to the airlock to validate all the steps of the EVA procedure, including off-nominals. The cosmonauts will also operate umbilical cords, locks, tools, etc.
The EVA scheduled for Nov 15, 5.30 p.m. MSK, is to last about 5 hours 55 minutes. It will cover mounting of the universal platform for scientific payloads on the outer surface of Zvezda module, Test experiment which implies sampling of the ISS outer surface, demounting of the Robotik monoblock from Zvezda surface, photo-imaging of the IPI-SM plasma injector, installation of the soft hand-rail on the Pirs module, installation of the SKK cassette on the Poisk module, operations with Zvezda and Poisk scientific hardware.
This is to be the first space walk for Skripochka, and the second one for Yurchikin during this expedition. Yurchikhin will also mark a kind of jubilee, as this will be the 5th EVA in his orbital flight career.

Just a heads-up: NTV coverage has started. The spacewalkers are inside the Pirs airlock preparing to egress on schedule.
-
Oh we have a thread. Anyone willing to provide some coverage (doesn't have to be full on like a Shuttle EVA), it'd be appreciated.

I will throw up some snaps from time to time as work permits
-
I won't be able to do much due to work but will chip in if I can.
-
-
I'll chip in where I can, too.
A shot of DC-1.
-
Great stuff. If a few people chip in, the combination will be great :)
-
They are working on depres in DC-1. Stopped to preform leak-checks
(It's 22.40 pm here in Hong Kong and I have an exam in Cantonese tomorrow so can't help out the whole EVA but can as previous posters chip in from time to time)
-
The EVA was scheduled to begin at 2.30 GMT so they are running a little behind schedule and the EVA is planned to last 6h 10m
-
Switching the Orlan suits to battery power.
Can you call the Orlan suits EMUs?
-
-
Coming up on a 4 min LOS so we will probably miss the start of the EVA since they will start opening the hatch as soon as they have switched their suits to battery power.

Setting up tethers and equipment
8.54am CET is the official beginning of EVA
-
Fyodor (EV-1) has the all-white suit
Oleg (EV-2) has 2 red stripes on the back
-
The crew has now moved from DC-1 to SM
First task is:
Install the URM-D portable multipurpose workstation on Plane IV of
the SM RO (Work Compartment) LD (Large Diameter).

Interesting, here (http://www.nasa.gov/mission_pages/station/expeditions/expedition25/russian_eva26.html)is written sth else :
"Monday’s spacewalk will be the fifth for Yurchikhin, who will wear the spacesuit marked with red stripes and the first for Skripochka, who will wear the suit with blue stripes. "

You are probably right my feed is bad but it looked like Fyodors was completely white
-
According to NASA PAO this is the first russian EVA preformed not just over Russian ground-stations since data is now feed through TDRS/MCC-H to MCC-M
-
CMG are maintaining attitude control, don't they usually use russian attitude control during russian EVAs?
-
Oleg and Fyodor are both working on the set-up of the workstation install on the SM
-
-
Gotta love this conversation
"did you break it?"
"of course"
-
We can now get Oleg's helmet cam through the ISS feed
-

Yup, that is correct. For reference, here is more info from the Expedition 25 thread:
From ISS On-Orbit Status Report for 10/11/2010.
RS EVA Flight Rule Change:
IMMT (ISS Mission Management Team) today approved a change in a Flight Rule which in the past called for RS EVA to take place only over RGSs (Russian Ground Sites) for downlinking Orlan suit telemetry via VHF (Very High Frequency). ISS, Soyuz, and Orlan suits utilize VHF-2 frequency pair. VHF-2 up to now had been limited to spacecraft emergencies or any contingency scenarios. The FR change allows Orlan spacesuit EVA operations over CONUS (Continental US) using the VHF-2 channel as well as spacecraft emergencies and contingencies. Use of VHF over CONUS requires GSFC network director pre-coordination due to frequency proximity to those of general aviation.

helmet cam views..

They are working on the installation of workstation
I don't know it it's the translator but the conversation between the crew sounds really funny from time to time
-
CMG are maintaining attitude control, don't they usually use russian attitude control during russian EVAs?
I thought also that it was played like that but now I'm not sure. Probably Space Pete will know :)
-
-
It is hard to follow along with updates since they don't use the same system with an IVA that reads from a check-list. We can mostly hear the conversation between Oleg and Fyodor.
As a side-note the best russian translator I heard on NASA TV just came on.
-
First area of attachment complete and finally checks are in place to make sure it's secure before moving on to next location
-
If I understood correctly they are just installing gap-spanners before they start driving the 4 bolts that will hold the workstation in place.

On the last Russian EVA (25), attitude control was handed over from USOS CMGs to RS Thrusters prior to egress. So I don't know why it's different this time. It could be an error on the part of the PAO.

It might be depending on their work location; if they are in the way for the thrusters but I'm not sure.
-
Reminding the crew to make sure their temperature in the suits are right.
Night-pass now so asked to remove covers.

MCC reminding the crew to take rests
-
Quiet on the loop as ISS heads out over the Indian Ocean
-
Something floated away so they will do an inventory shortly to find out what that was.
They want the crew to rest for at least 10 minutes.
-
Another great quote from Oleg or Fyodor when asked to take a break and MCC-M is making sure they really do take one:
"we are both adults, right"
-
-
As they have been working on the workstation they have also taken samples of the outside of the SM for later examination
(o Conduct space experiment "Test" on SM & DC-1 (i.e., take samples
from external surfaces).)
-
reminder of where everyone is
-
NASA PAO stating that Kaleri and Kelly have to stay in their Soyuz when they in fact freely move around in MRM-2 as well. When will the PAOs stop making these basic mistakes?

-
The bolts for the workstation are installed and they are working on tightening them

Doing inventory check
(sorry for my bad coverage but I have to study for my exam at the same time, and I truly think Cantonese is harder to learn than to fly the shuttle :-[)
-
The crew is now translation the the next task
Next task is to remove a experiment (Expose-R) from the outside of the SM

You're doing fine, and it's appreciated (for those who can't always use streaming during work hours)
-
Sounds like they mixed up some of the tethers
-
-
On the video it looks like Oleg is trying to tangle out his tethers while the loop is quiet.
-
He has worked it out and are now continuing.
-
-
-
Ground asking if solar array rotation will interfere with their translation route.
-
Solar rotation in work
-
They are at the next station and beginning to prepare for experiment removal.

just noticed - is this discolouration on the handle or paint missing?
-

-
Disconnecting cables connected to Expose-R

Looks like missing paint.
Great coverage, more than I had expected, especially for a non-shuttle EVA.
-
ground - "you must be getting cold"
Oleg - "no"
ground - "are you sure"
Oleg - "yes"
ground - "you're temperature seems to be low"
Oleg - "well i think I will have enough time to get warm today"
-
Oleg - "I'm like a maid here with a towel"
Oleg must be working with wiping down the Kontur science hardware
-
-
Oleg is starting to slightly moving the hardware away from it's mounting point on the SM.
-
Experiment removed from the SM and are now being transferred to the DC-1.
-
-
-
As ISS heads into a audio LOS the crew keeps working on the outside of DC-1 installing an experiment.
-
-
Bringing out the camera to take some photos of the installation.
-
It is quiet on the loop as I have to leave to get some sleep before a long day tomorrow.

the depress is done on Russian control. During the EVA it is usually CMGs unless the location/activities dictate otherwise.

Wouldn't these flakes require immdiate mitigation in order not to add to any more debris in orbit that might impact a Shuttle or other spacecraft ??

Russian Cosmonauts Returned to the ISS after EVA.
Russian cosmonauts completed their EVA activities outside the International Space Station.
Fyodor Yurchikhin and Oleg Skripochka returned to the station at 00.23 MSK, Nov. 16, after a 6-hour, 28-minute excursion.
The spacewalk was the fifth for Yurchikhin, and the first for Skripochka.
Cosmonauts successfully completed a set of planned EVA operations, which included installation of multipurpose workstation on the starboard side of the Zvezda service module’s large-diameter section, cleaning and removing a robotics experiment known as Kontur, installing a new materials experiment on a handrail on the Rassvet module, collecting samples from the exterior of Zvezda and Pirs, installation of the soft hand-rail on the Pirs module, installation of the SKK cassette on the Poisk module.
They also removed a television camera from the Rassvet docking compartment.

Superb work guys! Really appreciated.
Seconded!
That was great teamwork.
Of course now I'm concerned about the flaking paint...maybe a MLI blanket could be made & fitted? Pain in the butt no matter what is attempted. Can't believe it would be left like that.

Successful premiere – German robotic arm completes its five-year ISS mission.
Germany's first experiment in space robotics has now come to an end. On the evening of 15 November 2010, Russian cosmonauts Fyodor Yurichikhin and Oleg Skripochka performed a space walk during which they removed the Rokviss robotic arm developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) from the experimental platform on the Russian service module Svezda and took it inside the ISS. By 2 November 2010, the Rokviss team from the DLR Robotics and Mechatronics Center in Oberpfaffenhofen had moved the robot arm into the required position for this operation. Only in this position could Rokviss be easily transported through the air lock and into the interior of the ISS.
For the last five and a half years – from 22 March 2005 until 2 November 2010 – this robot arm, measuring 50 centimetres in length and weighing seven kilograms, has been operating in space and has completed somewhere in the region of 500 successful tests. With its two articulated joints and a metal finger, Rokviss has been able to perform high-precision work in space.
Four to six contacts a month
The technology experiment was controlled either fully automatically or by means of a technique known as telepresence operation – remote control by the DLR Rokviss project team based in Oberpfaffenhofen. Four to six times a month, the researchers established contact with the robot arm, whenever the ISS passed over the reception area of the antenna system at the DLR facility in Weilheim, near Oberpfaffenhofen, thereby making the transfer of data possible.
The aim of the experiment was to test and verify new hardware and powerful robot control concepts during real mission operations. In future, this technology will support astronauts and lighten their workload during complex tasks, and it will also help to repair satellites in orbit. Conditions in space are radically different from those on Earth; there is no air and temperatures inside the robot joints range from minus 20 to plus 60 degrees Celsius.
However, removal of Rokviss from the ISS does not complete the work of the DLR researchers. By March 2011, the two joint units are to be unfastened from their baseplate and the camera unit is also scheduled for disassembly. This is the only way to get the joints to fit in the small storage space available on the Soyuz capsule in which they are to be returned to Earth. By the end of April 2011, project manager Klaus Landzettel and his colleagues expect Rokviss to be back in the DLR Robotics and Mechatronics Center in Oberpfaffenhofen. Then, by carefully examining the extent of the mechanical wear, further essential information can be obtained and then applied to the building of future space robots.

Expedition 25 - Russian EVA Highlights - November 15
http://www.space-multimedia.nl.eu.org/index.php?option=com_content&view=article&id=6295

Uh, what just happened, and how? Look at the altitude change....
ISS On-Orbit Status 11/16/10
http://www.nasa.gov/directorates/somd/reports/iss_reports/
All ISS systems continue to function nominally, except those noted previously or below.
Wake – 6:00am EST (day shortened by 5 hrs); Sleep – 4:30pm (returning to nominal).
The Russian Orlan EVA-26 by FE-2 Oleg Skripochka & FE-5 Fyodor Yurchikhin concluded successfully last night at 4:22pm EST, with a total duration of 6h 27m (begin: 9:55am). It was the first EVA to utilize the Orlan telemetry via S-Band matching unit, instead of executing the EVA on VHF over RGS (Russian Ground Sites). Russian EVA specialists reported successful telemetry throughout the EVA, i.e., also over CONUS (Continental US).
Tasks completed by the spacewalkers were –
Installation of the URM-D portable multipurpose workstation in Plane IV (starboard) on the SM RO l.d. (Service Module Working Compartment large diameter);
Removal of the ESA/German ROKVISS hardware and stowing it in DC-1 (Docking Compartment 1);
Installation of SKK removable exposure plates on MRM2;
Installation of DC-1 Gap Spanner
Collecting four samples from underneath MLI (Multi-Layered Insulation) at two locations: (1) on the SM l.d. near the Elektron hydrogen-vent, (2) on the DC-1; purpose: looking for the existence of bio-organisms and FORP (Fuel/Oxidizer Reactive Products) beneath MLI; and
Removal of the MRM1 TV camera from the zenith location and bringing it inside the DC-1 for future EVA deployment (Note: camera could not be relocated on the MRM1 and installed as planned due to interference with some insulation at the final site).
Mean altitude gain in the last 24 hours – 171 m (due to RS EVA-26)
-
Uh, what just happened, and how? Look at the altitude change....
Mean altitude gain in the last 24 hours – 171 m (due to RS EVA-26)
Obviously with the amount of paint that peeled off during the EVA the entire complex became lighter and therefore gained altitute.. ;) - "set sarcasm button=off"

This thread is the only place where I've heard about the removal of EXPOSE-R. TsUP and NASA (and anik !) don't mention it.
Are you sure it was removed during VKD-26 ?
-
From the beginning of the thread:
http://www.nasa.gov/images/content/499764main_r26_RS_EVA_26_task_list.jpg
-
Yes, but even ESA doesn't mention this activity. Are you sure it wasn't deferred to VKD-27 (or later), as it is the case for IPI-SM ?
-

From what I remember they removed of an experiment but I never heard the name of it. According the the work-list Expose-R was the only experiment to be removed to I assumed it was Expose-R that was removed.
-
The experiments that were removed were:
• KONTUR ("ROKVISS" robotics) monoblock.
• EXPOSE-R.
• IPI-SM monoblock unit (accelerator channel) of the IMPULSE plasma pulse injector.
