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.

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.

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.

:)

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.

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 :)

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

:)

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.

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.

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.

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)

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.
