For the long-term Russian sleep study, FE-1 Oleg Kononenko terminated his third MBI-12 SONOKARD experiment session upon wake-up by taking the recording device from his SONOKARD sports shirt pocket and later copying the measurements to the RSE-MED laptop for subsequent downlink to the ground.

CDR Sergey Volkov in turn will start his third overnight MBI-12 session tonight. (SONOKARD objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.)

To provide cooling for the ground-commanded activation of the U.S. CDRA (Carbon Dioxide Removal Assembly), FE-2 Reisman connected the regular ITCS LTL (Internal Thermal Control System/Low Temperature Loop) coolant jumper connection to the LAB1D6 rack. (CDRA was activated today at 4:15am-4:45am EDT to reduce cabin CO2 levels.)

After CDR Volkov set up the NOA/Nitric Oxide Analyzer (MBI-21) experiment, he and Kononenko completed a data take session (his second, Oleg's first), later filling in the electronic log book on the RSE1 laptop for downlink and restowing the hardware. Each subject took two NO (Nitric Oxide) measurements in exhaled air. (Purpose of the ESA experiment ESANO1, consisting of the 'Platon' analyzer and its power supply, is to monitor expired NO in the subject's exhaled air to detect signs of airway inflammation and indications of venous gas emboli (bubbles) that may be caused by inhalation of pollutants in the closed environment of the ISS cabin and increased risk of decompression sickness.)

FE-2 Reisman made further preparations for the arrival of the JPM (Japanese Experiment Module Pressurized Module) next week by attaching the JTVE (JEM TV Camera Equipment) on the boom and returning it to stowage. (For his work in the JLP (JEM Logistics Module Pressurized Section), Garrett briefly activated the JLP MKAM (Minimum Keep-Alive Monitor) fan and temporarily moved the JLP's PBA (Portable Breathing Apparatus) from its location COL1PF in the COL (Columbus Orbital Laboratory) to the JLP endcone (JLP1F3). Afterwards, Garrett deactivated the JLP MKAM fan and returned the PBA to its COL location.)

Also in the JLP, the FE-2 repositioned the front bracket of the DMS1 rack to eliminate future interference with the rack's fire port.

Starting a new round of preventive ventilation system maintenance in the Russian Segment (RS), Volkov cleaned Group A fan screens in the Service Module (SM) and inspected equipment & structural elements in the maintenance areas to check for residue & condensate, taking photographs of the latter if found, for subsequent downlink.

Reisman meanwhile performed the periodic 5-min checkup on active U.S. payloads, i.e., cleaning the ANITA (Analyzing Interferometer for Ambient Air) inlet plus inspecting and filter cleaning of the CGBA-5 (Commercial Generic Bioprocessing Apparatus 5) incubator payload. (The CGBA incubator is controlled from the ground, with automatic video downlinked to Earth. ANITA monitors low levels of potential gaseous contaminants in the ISS cabin atmosphere with a capability of simultaneously monitoring 32 gaseous contaminants. The experiment is testing the accuracy and reliability of this technology as a potential next-generation atmosphere trace-gas monitoring system for ISS and future spacecraft. This is a cooperative investigation with ESA.)

The CDR completed the routine maintenance of the SM's SOZh/ECLSS system, including ASU toilet facilities systems/replaceables. (Regular daily SOZh maintenance consists of replacement of the KTO & KBO solid waste containers, replacement of an EDV-SV waste water and EDV-U urine container, and processing U.S. condensate water as it becomes available in a filled CWC from the Lab humidifier.)

As part of the ECLSS servicing, Sergey also performed the periodic functional check of the IP-1 airflow sensors in the various RS hatchways. (The inspection includes the passageways PrK (SM Transfer Compartment) -ATV, PrK -RO (SM Working Compartment), PkhO (SM Transfer Tunnel) -RO, PkhO -DC1, PkhO -FGB PGO, FGB PGO -FGB GA, FGB GA -Node-1.)

FE-1 Kononenko ran a standard checkout/test on the AST spectrometer of the Matryoshka-R (RBO-3) radiation payload on FGB panel 429 and its ALC-948 memory card, using the RSK-1 laptop. (Purpose of the test was to ascertain the continued usability of the 948 memory card and the AST at its FGB location. RBO-3 has taken over the former ESA/RSC-Energia experiment ALC (ALTCRISS/Alteino Long Term monitoring of Cosmic Rays on the ISS) with its AST Spectrometer and ALC equipment.)

In preparation for the subsequent R&R (removal & replacement) of the BSV-M Master Clock unit in the SM, Kononenko switched the Russian Vozdukh CO2 removal system to automated mode on both beds. After the R&R, the system was returned to manual Mode 5 via the on-board computer system. (Mode 5 uses 2 adsorbent cartridges with 10 min cycle time, a vacuum pump cycle time of 1 min, plus 40% airflow during sleep, 60-80% during the day, and 100% during physical exercise, for 3-4 crewmembers.)

The R&R, by Oleg, of one (A1) of the two redundant BSV-M (Frequency & Time Synchronization System, i.e., Master Clock) units has been pending since last December, awaiting the arrival of a new BSV-MA1 unit on the last Progress cargo ship. After the installation of the new clock unit (with the BITS2-12 Onboard Telemetry Measurement System turned off), the clock was activated on TsUP Go and adjusted manually. Upon nominal operation, Vozdukh was to be switched back to manual mode. (BSV-M A1 is needed for nominal operation with the payload server which had temporarily been switched to BSV-M A2 by FE-1 Malenchenko on 12/23.)

Later, with the IK0501 GA (Gas Analyzer) of the SOGS Pressure Control & Atmospheric Monitoring System deactivated, Sergey Volkov installed and connected a new BKS (Onboard Cable Network) telemetry cable harness between the IK0501 and the BITS2-12.

Volkov completed the periodic (about twice a month) replenishing of the Elektron oxygen generator's water supply for electrolysis, filling the KOV EDV container with water collected in CWC (Contingency Water Container) #1050 from the Lab CCAA (Common Cabin Air Assembly) dehumidifier. (The 40-minute procedure is specially designed to prevent air bubbles larger than ~10 mm from getting into the BZh Liquid Unit where they could cause Elektron shutdown.)

Garrett conducted the periodic offloading of the Lab CCAA (Common Cabin Air Assembly) dehumidifier's condensate tank, filling a CWC (Contingency Water Container, #1054) with the collected water slated for processing. No samples were required this time. (Estimated offload time before reaching the tank's neutral point (leaving ~6 kg in the tank): ~20 min.)

During the untended filling process, Reisman had 30 min reserved for personal departure preparations.

Garrett also had an additional hour set aside for more equipment prepacking for return on the Shuttle.

The FE-2 activated the SAMS ICU (Space Acceleration Measurement System Interim Control Unit) in its Drawer 1 in the LAP2 Rack. (SAMS measures structural dynamics (vibrational) data.)

In preparation for the upcoming STS-124 spacewalks, the two Flight Engineers spent time in the US Airlock checking out three PGTs (Pistol Grip Tools, #1001, #1005, #1008), including inspection of their collars and also two SAFER (Simplified Aid for EVA Rescue) units (#1004 & #1007.)

CDR Volkov meanwhile had ~2 hrs set aside for continuing the annual inspection and photo-documentation of window panes in the SM, started earlier (5/14). The observed defects were recorded in image and text files on the RSK1 laptop for subsequent downlink via U.S. OCA assets. (Objective of the inspection, which uses a digital still camera (Nikon D1X w/SB-28DX flash) and voice recorder, was to assess the pane surfaces on SM windows 6, 7, 8, 12, and EV hatch VP2 for any changes (new cavities, scratches, new or expanded old stains or discolorations affecting transparency properties) since the last inspection, performed by Oleg Kotov on 6/26/07. The new assessment will be compared to the earlier observations. Defects are measured with the parallax method which uses eyeball-sighting with a ruler and a right isosceles triangle to determine the defects' size and position with respect to the window's internal surface (parallax being the apparent change in an object's position resulting from changing the observer's position).)

Garrett retrieved two EGSAs (Element Ground Strap Assemblies) from their stowage bag for relocation to a JPM/JLP-designated bag in Node-2.

Also in Node-2, Reisman uninstalled and removed a failed RFCA (Rack Flow Control Assembly) of the ITCS (Internal Thermal Control System). During the 1J docked period, an accumulator from one of the JEM racks is to be installed in its place, and the failed RFCA will be returned.

Oleg performed the daily IMS (Inventory Management System) maintenance, updating/editing its standard 'delta file' including stowage locations, for the regular weekly automated export/import to its three databases on the ground (Houston, Moscow, Baikonur).

Working on the MELFI (Minus Eighty Degree Laboratory Freezer for the ISS), Reisman moved the Japanese CW/RW (Cell Wall/Resist Wall) KFT kits with their harvested RNA samples from the +2C dewar to a -95C dewar.

From their discretionary 'time permitting' task list, CDR Volkov & FE-1 Kononenko performed more Progress 29P unloading & cargo transfers, logging movements in the IMS.

Garrett completed the periodic (monthly) inspection of the RED (Resistive Exercise Device) canister cords and accessories.

The crew conducted their regular 2.5-hr. physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (CDR, FE-2), TVIS treadmill (FE-1), RED (CDR, FE-1, FE-2) and VELO bike with bungee cord load trainer (CDR).

Afterwards, Reisman transferred the crew's exercise data file to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM (Heart Rate Monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

At ~10:00am EDT, the ISS crew held its weekly teleconference with ISS Program Management at JSC/Houston via Private S/G2, S-band/audio.

At ~4:40pm, FE-2 Reisman is scheduled for his weekly PFC (Private Family Conference) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on an SSC laptop),

ATV Water Transfer Update: The amount of US condensate water transferred to the ATV 'Jules Verne' tanks from 4 EDV containers was about 88 liters

CEO (Crew Earth Observation) photo target uplinked for today was South Tibesti Megafans, Chad (ISS had a nadir pass over the Tibesti megafans of Chad. Looking for discontinuous and overlapping stream channels - interpreted to be the result of shifting river courses in the region during a wetter climate (approximately 8000 years ago). Overlapping frames, taken along track, were requested).
