They will install fasteners on all three of these antennas. The fasteners are designed to prevent the antenna covers from inadvertently coming off – an issue observed back in August 2013.
This task will be followed by a visual check of their spacesuits, glove cleaning, and jettisoning of used towels.
The next activity on the EVA timeline is photography of the Expose-R experiment.
The experiment examines how microgravity and the conditions outside the ISS affect different biological samples.
The pictures taken will reveal to investigators whether there has been any change to the materials involved with this experiment.
Another experiment that the cosmonauts will work with is the Obstanovka experiment, which investigates plasma wave processes in the vicinity of the ISS.
Commander Padalka will dismantle a sensor unit and stow it in his crew lock bag to bring the sensor inside the station towards the end of the spacewalk.
Next up will be the installation of another gap spanner and sampling of a radiator panel surface as part of the Test experiment.
More sampling will take place near the Russian environmental and life support systems overboard vents. The systems sampled will be Vozdukh (carbon dioxide scrubbing) and Elektron (oxygen generation).
After the sampling, the cosmonaut duo will return back to the airlock and stow their crew lock bag which by then will contain the sensor unit from Obstanovka and the used sampling kits. They will retrieve more equipment related to the antenna work and also a brand new antenna to replace the WAL6 antenna.
Next, the EVA crew will install fasteners on the WAL4 antenna.
The final antenna maintenance task is to cut off cabling from the WAL6 antenna, remove the antenna and install its replacement. After they route and connect all the necessary cables for the new antenna, the two will head back to the airlock and jettison the old antenna.
Finally, the spacewalkers will translate to the Poisk module, where they will reposition BKDO, a piece of equipment which measures rocket engine plume impingements on the station’s hull.
Then, they will head back to the airlock to wrap up the EVA. The total duration of the excursion is planned to be 6 hours 28 minutes.

Cosmonauts Working Outside for Russian Spacewalk
Cosmonaut Gennady Padalka takes a photograph during a spacewalk three years ago.
NASA Television will provide live coverage of a Russian spacewalk conducted from the International Space Station beginning at 9:45 a.m. EDT. The spacewalk is scheduled to begin at 10:14 a.m. and run about six hours.
Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency will venture outside the orbiting outpost where they will rig new equipment on the Russian segment of the complex and conduct a detailed photographic inspection of its exterior.

International Space Station Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency began a planned approximately 6-hour spacewalk from the Earth-facing Pirs Docking Compartment at 10:20 a.m. EDT.
Padalka will be designated extravehicular crew member 1 (EV1) and Kornienko will be extravehicular crew member 2 (EV2). Both will wear Russian Orlan spacesuits bearing blue stripes. Their suits are equipped with NASA helmet cameras to provide close-up views of the work they are performing outside the station.
This is the 188th spacewalk in support of space station assembly and maintenance.
The spacewalking duo will install devices called gap spanners on the hull of the station that will facilitate the movement of crew members on future spacewalks. They also will clean residue off of the windows of the Zvezda Service Module, install fasteners on communications antennas, replace an aging antenna used for the rendezvous and docking of visiting vehicles at Russian docking ports, and photograph a variety of locations and hardware on Zvezda and nearby modules. An experiment designed to measure the space environment first deployed in 2013 will be retrieved and brought inside for its return to Earth.
Flight controllers at the Russian Mission Control Center in Korolev, outside of Moscow, are providing primary support for the spacewalk and coordinating with Mission Control at NASA’s Johnson Space Center in Houston.
