From ISS On-Orbit Status Report for 26/07/2010:

Shifted crew day/night cycle:
Due to tonight's Russian EVA-25, the wake-up time of the station residents has been shifted by 12 hours 40 minutes to 6:40 PM GMT.
Sleep = tomorrow (27/07) at 3:00 PM GMT.

For tonight's EVA, CDR Alexander Skvortsov in the course of the day:
• Set up the MPEG-2 video transmission system on Ku-band.
• Monitored the TV signal on the SSC-1 (Space Station Computer-1)
  laptop during the subsequent MPEG-2 transmission test (Ku-band) with
  the ground.
• Prepared MRM-2 & Soyuz TMA-18/22S for the EVA.
• Supported ground-commanded close-down of the Elektron O2
  generator by performing the regular N2 purge.
• Removed the ventilation air ducts from DC-1 (skip B3 fan removal) and MRM-2.
• Conducted other routine pre-EVA ISS onboard systems configuration,
  e.g., closing SM window shutters for protection.
• Started with FE-2 Tracy Caldwell-Dyson the isolation period in MRM-2
  during the EVA.

On her part, Tracy joined Alexander in MRM-2, where she:
• Had gathered CTBs (Cargo Transfer Bags) and required equipment for audit and
  reconfiguration.
• Collected fully-charged batteries from deployed SSCs, powered down
  SSC-18, and relocated batteries and SSC to MRM-2 for use during
  MRM-2 isolation.
• Configured her Pro K diet selection by organizing food items per crew
  preference for another Pro K session series.
• Reorganized the "battery pantry" CTB for easier crew use and audit.
• Reviewed the procedures and material of the
  ECWS (EMU Caution & Warning Simulator) OBT (Onboard Trainer).

FE-3 Mikhail Kornienko & FE-5 Fyodor Yurchikhin made final preparations for their EVA tonight by:
• Checking the EVA cameras by "test firing" them and transferred them to DC-1.
• Checking out the Orlan-M spacesuits and their systems, as well as the
  suit interface control panels (BSS) in DC-1 & SM PkhO
  (Transfer Compartment).
• Retesting the BK-3 primary & backup O2 tanks of the Orlans and DC-1.
• Disassembling the DC-1 air duct, but leaving the V3 fan in place.
• Setting up the STTS communications/telemetry links necessary for the
  EVA from DC-1, including switching over the caution & warning system
  from the regular PSS console to the EVA support panel (POV).
  [Most activities are paced by RGS (Russian Ground Site) comm.
  window passes].
• Testing the bio-medical parameter telemetry to RGS, including
  VHF (Very High Frequency)/voice & biomedical electrode belt and
  *telemetry hookups via the BSS (later by the wireless in-suit Tranzit-B
  radio telemetry system) for vital signs and equipment monitoring.

EVA-25 will begin tomorrow (27/07) morning at ~3:45 AM GMT.

International Space Station operations team met late yesterday to review results of last week’s dry run for using Canadarm2 and its Dextre robotic helper to replace a failed Remote Power Control Module (RPCM) in the P1 truss. The team elected to defer additional work with Dextre until additional analysis of the forces required to remove the smart circuit breaker from its housing in the truss is completed.

From ISS On-Orbit Status Report for 27/07/2010:

Today's sleep/wake cycle:
Wake last night = 6:40 PM GMT. Sleep = 3:00 PM GMT today (until 6:00 AM GMT tomorrow morning).

Russian EVA-25 spacewalk by FE-3 Mikhail Kornienko & FE-5 Fyodor Yurchikhin began at 4:11 AM GMT (26 minutes behind schedule) and lasted 6 hours 42 minutes, concluding successfully at 10:53 AM GMT. Attitude control authority was handed over to Russian MCS (Motion Control System) thrusters at 1:25 AM GMT and returned to U.S. momentum management at ~4:05 PM GMT. All scheduled objectives were completed.

During the EVA, the two spacewalkers:
• Replaced the ATV Klest-154 video camera.
• Routed and mated external KURS-P AFU (Antenna Feeder Device)
  MRM-1-to-FGB cables to the FGB.
• Routed and mated SUBA (Onboard Equipment Control System)
  Ethernet cables to the SM.
• Jettisoned the old ATV Klest-154 video camera.
• Brought the MRM-1 cable reels back inside the ISS (instead of jettisoning them as originally planned).
[The new SM ATV video camera that was installed was checked out successfully. The KURS cables have not yet been tested but Moscow plans to do that later this week. During the EVA, several objects were detected floating away from the ISS. One was tentatively identified as a cable clamp. The videos are being reviewed by the Russians to determine the identity of the other objects.]

After the conclusion of the EVA, Mikhail & Fyodor:
• 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.

CDR Alexander Skvortsov, who remained isolated in MRM-2 during EVA-25 with FE-2 Tracy Caldwell-Dyson:
• Opened the MRM-2-to-SM(SU) hatches.
• Installed the air ducts in SM, MRM-2 and DC-1.
• Supported the ground-commanded reactivation of the Russian Elektron
  O2 generator by monitoring the external temperature of its secondary
  purification unit (BD) for the first 10 minutes of operations to ensure
  that there was no overheating. [The gas analyzer used on the Elektron
  during nominal operations for detecting H2 in the O2 line (which could
  cause overheating) is not included in the control algorithm until 10
  minutes after Elektron startup.]
• Completed post-EVA MRM-2 reconfiguration to nominal and
  Soyuz TMA-18/22S deactivation.

After the EVA, Tracy:
• Relocated the SSC-18 (Station Support Computer-18) laptop from
  MRM-2 to its nominal plug-in location in the Cupola & returned
  batteries to deployed SSCs.
• Returned stowage equipment, CTBs (Cargo Transfer Bags) and other
  required hardware from MRM-2 to their nominal locations for
  reconfiguration.

From ISS On-Orbit Status Report for 28/07/2010:

FE-5 Fyodor Yurchikhin & FE-3 Mikhail Kornienko spent most of their workday on close-out activities after yesterday's EVA. Activities included:
• Holding an EVA debrief/close-out conference with ground personnel.
• Removing the BK-3 portable O2 repressurization tanks
  (primary & backup) from the DC-1 BSS (Orlan Interface Unit).
• Removing the BNP portable repress tank from the
  SM Work Compartment (RO) and relocating it to Soyuz TMA-19/23S.
• Removing the Orlan BRTA radio/telemetry unit batteries.
• Taking post-EVA radiation readings of the "Pille-MKS" dosimeters
  carried by the spacewalkers in their Orlan suits.
• Putting the EVA medical kits back in storage.
• Setting up the first 825M3 Orlan battery pack for complete
  discharge/recharge.
• Removing the US EMU lights, video cameras,
  REBAs (Rechargeable EVA Battery Assemblies) & electric power cables from
  the Orlan-MK suits for return to FE-2 Tracy Caldwell-Dyson.
• Refilling the Orlan feedwater bladders as required.
• Configuring the Orlan-MKs, umbilicals and BSS interface units
  for drying out & subsequent storage.
• Taking their post-EVA PMCs (Private Medical Conferences),
  via S-band & Ku-band audio/video.

Meanwhile, Tracy & FE-4 Doug Wheelock worked on preparatory tasks for their US EVA-15 on 05/08. Activities included:
• Gathering & configuring EVA tools.
• Installing REBA #1008 into EMU 3005 (Wheels) & REBA #1012 into EMU
  3009 (Tracy).
• Installing & checking out Video Camera #19 & HL (Helmet Light) #1008
  on EMU 3005 and Camera #20 & HL #1006 on EMU 3009.
• Checking out SAFER (Simplified Aid For EVA Rescue) units 1006 & 1007.

In final close-out activities after yesterday's EVA, CDR Alexander Skvortsov worked in DC-1 to re-integrate Progress M-05M/37P (docked at DC-1 Nadir) with the ISS by:
• Conducting a leak check on the DC-1/37P vestibule.
• Opening the DC-1/SU & SU/37P hatches and installing the QD
  screw clamps (BZV) of the docking & internal transfer mechanism
  (SSVP) to rigidize the coupling.
• Deactivating Progress.
• Installing the ventilation/heating air duct.
• Dismantling the docking mechanism between the cargo ship and DC-1.

Alexander also purged & charged the SrPK (air supply tankage) Section 2 of Progress M-06M/38P (docked at SM Aft) with N2 and later, on TsUP Go, was to repressurize the ISS cabin atmosphere with N2 from 38P to make up total pressure.

Quote from: NASA's main ISS webpage
The International Space Station crew members will not need to take shelter in their Soyuz spacecraft when a piece of debris from a Chinese satellite makes its closest pass by the station at 1:47 PM EDT/5:47 PM GMT today. Mission Control gave the all-clear to the Expedition 24 crew at 12:45 PM EDT/4:45 PM GMT, after additional tracking information showed the debris would not come any closer than 5 miles (8 kilometers).

Mission Control Centers in the U.S. and Russia have been keeping a close eye on the piece of orbital debris for the past several days, but the object has proven difficult to track precisely. Earlier in the week, tracking data on the debris showed that it would pass near the station, but not close enough to require a debris avoidance maneuver. Early Thursday, however, new tracking data on the object showed that it might pass close enough to require the crew members to take shelter in their Soyuz spacecraft when the debris made its closest approach. Additional tracking today showed the Soyuz sheltering was unnecessary.

In the on-orbit report of 17th july, it is written :

Quote
After configuring the usual pumping equipment (Compressor-M, hoses, adapters), Alex Skvortsov initiated the transfer of urine from 8 EDV-U containers to the empty BV1 Rodnik storage tank of Progress M-06M/38P at the SM Aft port. [After the urine had been transferred, the CDR flushed the tank with 5 L of disinfectant solution from an EDV w/Disinfectant, running the compressor for 4 min. Each of the spherical Rodnik tanks BV1 & BV2 consists of a hard shell with a soft membrane (bladder) composed of elastic fluoroplastic. The bladder is used to expel water from the tank by compressed air pumped into the tank volume surrounding the membrane and is leak-tested before urine transfers, i.e., with empty tanks, the bladders are expanded against the tank walls and checked for hermeticity.]

But the M-06M's BV1 had a leak, so how did they manage to achieve the transfer ?

From ISS On-Orbit Status Report for 29/07/2010:

In preparation of the planned installation of the PDGF on the exterior of the FGB during US EVA-15 by FE-2 Tracy Caldwell-Dyson & FE-4 Doug Wheelock (currently scheduled for 05/08), Doug configured the brackets for the Russian-built PDGF adapter ("rama" = frame), delivered on Progress M-05M/37P. [The additional PDGF with its power/data cabling, the first on the RS, will extend the "roving" range of the SSRMS, which moves itself inch-worm like from PDGF to PDGF.]
(NOTE: An image of the "rama" is attached (first image). The 3 brackets on the "rama" attach to the 3 mount points on the Port side of the FGB GA/Pressurized Adapter (shown in second image), and the PDGF then attaches to the "rama").

In DC-1, FE-3 Mikhail Kornienko terminated the discharge process on the first 825M3 Orlan battery pack in the ZU-S recharge unit and started it on the second set.

Wrapping up their post-EVA closeout activities, Mikhail & FE-5 Fyodor Yurchikhin returned EVA tools & equipment to stowage, updating the IMS appropriately.

In the JPM, FE-6 Shannon Walker successfully completed the first activation and checkout & functional test of the MELFI-3, which was delivered to the ISS in April on STS-131/19A. Later it was deactivated.

Payload Milestone:
An important milestone was completed today when 12 utilization racks were active at one time. Over the course of the day a combination of 12 of the following 13 payload racks were active and conducting or preparing to conduct weekly science operations: ER-1 (ExPrESS Rack-1), ER-2, ER-3, ER-4, ER-6, CIR (Combustion Integration Rack), FIR (Fluids Integrated Rack), MSG (Microgravity Science Glovebox), MELFI-1, MELFI-2, MELFI-3, SAIBO and RYUTAI.

Kurs MRM-1 Testing:
Following the Kurs cable installation task during Russian EVA-25 this week, TsUP-Moscow performed a Kurs test from the FGB Kurs equipment to MRM-1 antennas and did not receive good results due to incorrect uplink settings. Later the test was completed with the correct settings and successful results were achieved.

NASA announced that both spacewalkers had blue stripes. But according to these pictures from Roskosmos, this is not true. Yurtchikhin's Orlan-MK n°4 had blue stripes, Kornienko's Orlan-MK n°6 had red stripes.

According to MCC-H EVA-25 ended at 10:53 GMT and lasted 6 h 42 mins
and according to MCC-M it was longer by 1 minute !?

My theory is: different rounding of timing of hatch closure.

It's funny how the Russians don't care about privacy: apparently Yurchikhin needed phone numbers of some people to call and a few minutes ago, MCC-M gave him those two numbers for all the world to hear.
