NASA TV to Air Russian Spacewalk from International Space Station
 
NASA Television will broadcast live coverage of a six-hour spacewalk by two Russian crew members aboard the International Space Station beginning at 9 a.m. EDT Wednesday, Oct. 22.

Expedition 41 Commander Max Suraev and Flight Engineer Alexander Samokutyaev of the Russian Federal Space Agency will don Orlan spacesuits and exit the station’s Pirs airlock at 9:24 a.m. They will remove and jettison several pieces of hardware no longer needed on the Russian segment of the station and conduct a detailed photographic survey of the exterior surface of the Russian modules.

The spacewalk will be the 184th in support of space station assembly and maintenance, the third in as many weeks for Expedition 41 crew members, and the second career spacewalks for both Suraev and Samokutyaev.

Suraev will be designated as extravehicular (EV) crew member 1 and will wear an Orlan suit bearing red stripes. Samokutyaev will be designated as EV-2 and will wear a suit with blue stripes.

Tasks for Third Spacewalk of Expedition 41

Published on Oct 17, 2014
NASA Spacewalk Specialist Devan Bolch narrates this animation depicting the events scheduled for the Oct.22 spacewalk. Expedition 41 Commander Max Suraev and Flight Engineer Alexander Samokutyaev of the Russian Federal Space Agency (Roscosmos) will remove and jettison experiment hardware and antennas no longer needed on the Russian segment of the complex and perform a detailed photographic survey of the exterior of the Russian modules. It will be the third spacewalk in as many weeks for Expedition 41 crew members on the station, the 184th in support of space station assembly and maintenance, and the second for both Suraev and Samokutyaev.

Adding to the orbital debris environment and not getting much else done.  Why are they removing two KURs antennas?
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

All of the old KURS-A antennas will eventually be tossed given transition to new KURS-NA, GLONASS Navigation System, and the Phased array antennas being installed.

The removal of two Kurs-A antennas does not relate to what you said. They are on other side of Poisk module, not there where spacecraft docks. They are switched off. Probably they stand in the way of moving cosmonauts, so engineers decided to remove them.

Corrected!

They are not Kurs-A, but Kurs-P antennas. So the removal of two Kurs-P antennas does not relate to what you said. They are on other side of Poisk module, not there where spacecraft docks. They are switched off. Probably they stand in the way of moving cosmonauts, so engineers decided to remove them.

Were these used for the first MRM-2 docking, then deactivated?

Are your sure ? I thought they were part of Kurs-A system that was used to dock MIM-2 to SM in 2009.

Yes.

Oh, Nicolas, you and russianhalo117 are right, of course! They are Kurs-A antennas. I am sorry! But again their removal does not relate to what russianhalo117 said (Kurs-NA upgrade, etc.).

This will be the live thread tomorrow. Again, we'll need everyone to chip in with updates like the previous one. More so with this as I'll be missing with work for large chunks of it.

Radiometriya, the first object to be jettisoned, is a 106 kg experiment almost 2 metres across - I had forgotten it was
so big.  It was launched on Progress M-09M and installed during VKD-28 in Feb 2011.

The Expose-R (whose cover is to be retrieved) was installed in the August VKD-49 spacewalk.

I assume the Kurs-P antennas have been on Poisk since its launch.

VKD-29 ;)

They are Kurs-A antennas, and yes they were present at launch because they were needed to dock Poisk to Zvezda.
Some of the Kurs-P antennas, however, were added during VKD-24, on 14th January 2010.

Great job David on an awesome article overview!

Right then folks. We ALL need to chip in with coverage as I'm going to be missing for about half of this.
