Cosmonauts Anton Shkaplerov and Alexander Misurkin are also preparing for their next spacewalk set for next Friday when they open the Pirs docking compartment hatch at 10:34 a.m. The veteran station residents will don their Russian Orlan spacesuits for a near six-and-a-half-hour spacewalk outside the International Space Station’s Russian segment. The duo will retrieve science samples exposed to outer space and install a high gain antenna on the rear of the Zvezda service module.

NASA TV coverage starts 9:45 a.m.

NASA TV to Air Russian Spacewalk at the International Space Station
 
Two veteran Russian cosmonaut spacewalkers will venture outside the International Space Station on Friday, Feb. 2, for a planned 6.5-hour station servicing session. Live coverage of the spacewalk will air on NASA Television and the agency’s website beginning at 9:45 a.m. EST.

Expedition 54 Commander Alexander Misurkin and Flight Engineer Anton Shkaplerov of the Russian space agency Roscosmos are set to float out of the space station’s Pirs docking compartment airlock in Russian Orlan spacesuits at 10:34 a.m.

Misurkin and Shkaplerov’s primary objectives during the spacewalk will be to remove and jettison an electronics box for a high-gain communications antenna on the Zvezda service module and install an upgraded electronics box to communication between Russian flight controllers and the Russian modules of the orbital outpost. The cosmonauts also will take detailed photos of the exterior of the Russian modules and retrieve experiments housed on Zvezda’s hull.

The Russian spacewalk will be the fourth in Misurkin’s career and the second for Shkaplerov, as well as the 207th spacewalk in support of space station assembly and maintenance. Both of their suits will be marked with blue stripes.

From the ISS Expedition 54 thread:

Google translation:

Quote
You have to accomplish a spacewalk during the flight. What is the planned program?

- The main task of the output is to change the electronic unit at the antenna of the retransmission system "Luch". There is such a satellite antenna in the Russian segment that was delivered to the ISS along with the Zvezda service module during the assembly of the station. Then it was assumed that in the nearest future, satellite retransmitters "Ray" will appear and through them we will have a direct connection with the Earth. But, unfortunately, these were the 2000s and funding was inadequate, satellites were not created.

This antenna idled in space for 17 years, and although it physically works, but the element base there is already outdated. The satellites of the Luch system created today operate on a new element base. Therefore, in order to make the entire retransmission system for the ISS work, it is necessary to change the electronic unit on the antenna - the subscriber relay equipment.

The difficulty lies in the fact that when this service module was launched with the antenna, no one thought that it would have to change this unit in space. Therefore, we are going to have a very difficult and jeweled work: we will have to unscrew tens of bolts in thick gloves of the spacesuit, dismantle the block and put a new one. For this, three types of instruments were invented. We will unscrew one, if it does not go - the second, again not - the third. And earlier, during the previous exits, no one has tried to work in the place where the antenna is. I hope that we will do everything and we will have our onboard-to-Earth connection via the Luch retransmission system (currently the Russian segment uses the NASA retransmission system when the ISS is out of line of sight from Russia - TASS comment).

Probably, let's start some microsatellites

Also there are additional works during this exit. In particular, it will be necessary, if time is enough, to disconnect and dismantle the measuring blocks from the experiment "Furnishings" with subsequent disposal by the method of throwing away from the ISS, to take some samples off the cladding of the station.

Probably, we will start some microsatellites. They are launched in a certain direction with their hands, and it is necessary that they do not rotate. I plan to go to outer space on February 2.

"How do you like the new spacesuit?"

- In the new spacesuit added automatic temperature control - it's like in cars climate control. Earlier it was necessary to manually make it warmer or colder, depending on which side of the station is at the exit: on the sunny or shady. Now this is all done by the automation, which redistributes the water streams inside a special thermoregulating water suit, put on you under a spacesuit.

In the new spacesuit the material of the hermetic shell changed - it seems to have become tougher, well, it needs to go out and work, then I can make a conclusion.


What is the planned schedule for starting to use Luch relay and go beyond relying on ground stations in Russia alone? And what would the initial coverage area/time be?

A pair of empty Russian Orlan spacesuits (Orlan-MKS nr. 4 and MK nr. 6) are pictured inside the airlock of the Pirs docking compartment. The spacesuits will be worn during a Feb. 2 spacewalk with cosmonauts Alexander Misurkin and Anton Shkaplerov.

Not to be nitpicking, but the spacesuits are MKS nr.4 and MK nr.6.

A little A little summary of Procedure:
the two spacewalkers (wearing their thermal undergarments) entered the Pirs module where they began activating their suits and performing a series of checks.
As usual, the PKhO Transfer Compartment of Zvezda Service Module (with which Pirs and Poisk interface) is sealed off during Russian EVAs to serve as a backup airlock.
 
Inside Pirs, they ingressed their Orlan spacesuits. and then perform a series of leak checks, and MCC-M control that good telemetry and biomedical data are received from both crew members.
The crew completed a one-hour pre-breathe to remove nitrogen from their blood.

When all checks had returned good results, Alexander and Anton received the green light to start depressurizing the Pirs Airlock by opening its pressure release valve.
The depressurization included a hold for additional leak checks of the Orlan and the  airlock.

I've written an article and it'll go on site when the EVA begins.

The detailed spacewalk page for the previous Russian EVA is http://www.mcc.rsa.ru/out170817.htm
but I don't see one yet for this one (i.e.  http://www.mcc.rsa.ru/out020218.htm does not exist) - has anyone found one,
or does it not go up until after the EVA?
