Do you know what is a "ВЧ" cable ?
Thanks !

ВЧ - высокочастотный - high-frequency
НЧ - низкочастотный - low-frequency

14/01/2010:

The Russian Orlan EVA-24 spacewalk by FE-1 Maxim Suraev & FE-4 Oleg Kotov began at 5:05am EST and lasted 5h 44min, concluding successfully at 10:49am. Attitude control authority was handed over to Russian MCS (Motion Control System) thrusters at 2:50am and returned to U.S. momentum management at ~6:50am. All scheduled objectives were completed. The two spacewalkers:
  - Routed and mated Kurs-P SM (Service Module)-to-MRM2 cables
  - Routed and mated Ethernet SM-to-MRM2 cables
  - Installed docking targets, antennas, and two handrails on MRM2
  - Removed & returned a Biorisk experiment container from the DC-1
[This completes MRM2 (Mini Research Module 2) outfitting in preparation for future rendezvous operations. Besides the outfitting, the crew also jettisoned two MLI (Multi-Layer Insulation) bundles. EV1 noted that the "blurry" spot on his suit display observed during the Dry Run was also apparent during the EVA. In addition, both the Primary and Backup Fans were activated on EV2’s suit. The EV crew noted corrosion on the SM Hydrogen vent valve and possible MMOD strikes on the SM PkhO. Nominal SM Kurs system performance following the EVA was confirmed via testing.]

CDR Williams assisted EVA-24 preparations by readying the two EVA digital cameras, while FE-5 Noguchi closed the protective shutters of the Lab and Kibo JPM (JEM Pressurized Module) science windows and deactivated the onboard ham radio equipment to prevent stray RF interference with suit communications.

After conclusion of EVA-24 at ~10:49am, Oleg & Maxim:
  - Repressurized the SM PkhO transfer compartment
  - Conducted their second MO-9 “Urolux” biochemical urine test
  - Reset STTS communications in the SM/PkhO
  - Re-installed the air duct through the PkhO hatch
  - Restored systems configurations in the SM to pre-EVA conditions
  - Set up the Orlan-MK suits, umbilicals and BSS interface units for drying out

hhmmm...I wonder if that corrosion would be from free atomic oxygen around the station? Would love to see some images.

01/15/2010:

FE-4 Kotov & Suraev cleaned up after yesterday’s EVA-24 spacewalk. Specifically, Oleg & Maxim:
  - Held an EVA debrief/close-out conference with ground personnel at ~5:00am EST
  - Removed the BK-3 portable oxygen repressurization tanks (primary & backup) from the DC1 BSS (Orlan Interface Unit)
  - Repressurized the interior from the BNP portable repress tank #7 in the DC1 until empty
  - Removed the BNP portable repress tank from the SM Work Compartment (RO) and relocated it to Soyuz TMA-17/21S
  - Removed the Orlan BRTA radio/telemetry unit batteries
  - Took post-EVA radiation readings of the “Pille-MKS” dosimeters carried by the spacewalkers in their Orlan suits
  - Put the EVA medical kits back in storage
  - Downlinked EVA-24 digital photography
  - Set up the first 825M3 Orlan battery for complete discharge/recharge
  - Removed the US EMU (Extravehicular Mobility Unit) lights, video camera, REBA battery & electric power cable from Orlan-MK for return to CDR Williams
  - Refilled the Orlan feedwater bladders as required
  - Configured the Orlan-MK suits for drying out
  - Took their post-EVA PMCs (Private Medical Conferences), via S- & Ku-band audio/video, Oleg at ~12:05pm, Max at ~1:15pm

I have been told that, if Elektron works in a mode with the maximum power consumption, it allocates alkali, which promotes corrosion occurrence.

I did not notice these items on Russian spacesuits during yesterday's spacewalk.

Thanks anik!

Depending on how serious, another lesson learned, and maybe something to remedy in future, or at least to avoid, depending on the severity.

During the comentary Im sure I heard that the lights (as used on American suits) were not being used,but it was clear that the Russian versions were,are the Russian lights "new" ?

Here's a pic of both lights "on"
The lights on the right were being cycled on and off as I got the grab,

This type of lights (with diode lamps) are using on our spacesuits since spacewalk on February 22, 2007.

I knew they'd got lights but always asumed they were the American ones,

Our spacesuits got lights on Orlan-DM spacesuits (first use - on August 2, 1985) on Salyut-7 station. If I understand correctly, this type of lights (with two filament lamps in each light) have been used on Orlan-DM, Orlan-DMA and Orlan-M spacesuits (till February 22, 2007).

(see image 1)

From February 22, 2007 on Orlan-M and Orlan-MK spacesuits another type of lights (with 42 diode lamps in each light) is using.

(see image 2)

In many spacewalks on ISS we have used combination of Russian and US lights.

(see image 3)

Do you offer to read it in French? :)

On figure 12 it is not AR-2AR-VKA antenna, it is 4AO-VKA antenna. AR-2AR-VKA antenna has two dish-like objects on one stanchion (see image below).

01/17/2010:

In final close-out activities after the Orlan EVA on 1/14, Maxim & Oleg worked in the DC1 (Docking Compartment) to re-integrate the Progress 35P cargo ship, docked at the nadir port, with the ISS by:
  - Opening the hatches and installing the QD (quick disconnect) screw clamps (BZV) of the docking & internal transfer mechanism (SSVP) to rigidize the coupling
  - Installing the ventilation/heating air duct
  - Dismantling the docking mechanism (StM, Stykovochnovo mekhanizma) between the cargo ship and the DC-1

Would much rather see exterior shots of the ISS they must have taken.
