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.

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.

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)

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 ?

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 ?
