ISS On-Orbit Status 01/24/08

CDR Whitson and FE-2 Tani started out with the daily reading of SLEEP (Sleep-Wake Actigraphy and Light Exposure during Spaceflight) experiment data accumulated during the night, for logging and filling in questionnaire entries in the SLEEP session file on the HRF-1 laptop for downlink.

(To monitor the crewmembers' sleep/wake patterns and light exposure, Dan and Peggy wear a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.)

Dan Tani dismantled the InSPACE-2 (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment in the MSG (Microgravity Science Glovebox) and stowed the equipment, including the video gear.

CDR Whitson performed 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 termination (leaving ~6 kg in the tank): ~40 min.)

The CDR also conducted the weekly 10-min. CWC audit as part of on-going WDS (Water Delivery System) assessment of onboard water supplies. (Updated 'cue cards' based on the crew's water calldowns are sent up every other week (currently #16-0018O).)

Whitson and Tani set up and activated the OUM-PFE (Oxygen Uptake Measurement - Periodic Fitness Evaluation) equipment at the HRF-2 (Human Research Facility 2) rack for another session, requiring a CEVIS cycle ergometer workout. Both crewmembers then completed the evaluation protocol, wearing HRMs (Heart Rate Monitors), with each one in turn acting as subject and operator, obtaining measurements on each other during the workout. The CEVIS control panel required some crew intervention. (The equipment includes the HRF PFM/PAM (Pulmonary Function Module/Photoacoustic Analyzer Module), Mixing Bag System and GDS (Gas Delivery System). In a change to previous procedures, the calibration of the DPFM (Differential Pressure Flowmeter) was done manually for the first time. Later, Peggy and Dan updated the evaluation protocol, deactivated & stowed the gear, and powered down the OUM-PFE laptop. Purpose of OUM-PFE is to measure aerobic capacity during exercise within 14 days after arrival on ISS, and once monthly during routine PFEs. The data allows exercise physiologists & flight doctors to assess the crew's health & fitness and to provide data for modifying & updating crew-specific exercise regimes. PFE-OUM is a collaborative effort between NASA and ESA (European Space Agency).)

FE-1 Malenchenko again had several hours for trash transfers to Progress M-62/27P for disposal (2/4), tracking movements in the IMS (Inventory Management System).

Yuri also performed the daily monitoring, picture-taking and downloading on the newly set up BIO-5 Rasteniya-2 ("Plants-2") experiment. (Rasteniya-2, researches growth and development of plants (peas) under spaceflight conditions in the Lada-12 greenhouse from IBMP (Institute of Bio-Medical Problems, Russian: IMBP). During its operation, the experiment requires regular daily maintenance of the experiment involving monitoring of seedling growth, humidity measurements, moistening of the substrate if necessary, and photo/video recording. During the duration of the BI O-5 experiment, students of the Moscow City Palace for Youth Creativity of the Meshchansky inter-regional center #15 in Moscow) and the Prince of Oldenburg Lyceum in St. Petersburg will be cultivating plants in parallel on the ground and conducting comparative observation of plant growth and development under gravity and zero-gravity conditions. They are receiving the photo images taken by Yuri.)

With the Elektron-VM O2 (oxygen) generator currently off, a 5-min cabin air refresh was to be performed by the FE-1 from Progress 27P storage (SrPK) as required.

Malenchenko conducted a search to gather the necessary equipment for the ATV (Automated Transfer Vehicle) hand controller of the PCE (Proximity Communications Equipment; Russian: MBRL) system preparatory to its installation on 1/26 for testing. (To assess the impact of the installed Matryoshka gear on the planned installation of the PCE hand controller box, TsUP-Moscow sent up a picture of the PCE installed on the ISS in 2005.)

CDR Whitson worked in the U.S. Airlock on preparations of the spacesuits for herself and Dan for EVA-14 on 1/30. (After terminating battery recharge, Peggy installed REBA 1005 in EMU 3018 (Peggy's) and REBA 1011 in EMU 3006 (Dan's), PGT (Pistol Grip Tool) batteries 1008 & 1009 in the EV1 & EV2 PGTs, PGT battery 1004 in the spare PGT, HL (Helmet Light) 1015 & 1017 on EMU 3018, and HL 1019 & 1021 on EMU 3006.)

The CDR also installed the METOX (Metal Oxide) CO2 absorber canisters (in lieu of LiOH cans) in the suits, and checked out the EMUs and the SAFER (Simplified Aid for EVA Rescue) units

As part of his standard fitness evaluation, Malenchenko undertook the Russian MO-5 MedOps protocol of Cardiovascular Evaluation during Graded Exercises on the VELO cycle ergometer, with CDR Whitson assisting as CMO (Crew Medical Officer). (The 50-min assessment, supported by ground specialist tagup via VHF and telemetry monitoring, uses the Gamma-1 ECG equipment with biomed harness, skin electrodes and a blood pressure and rheoplethysmograph cuff wired to the cycle ergometer's instrumentation panels. For the graded exercise, the subject works the pedals after a prescribed program at load settings of 125, 150, and 175 watts for three minutes each. Data output involves a kinetocardiogram, rheoplethysmogram, rheoencephalogram and a temporal pulsogram.)

The FE-2 took air samples for the periodic (currently daily) atmospheric status check for ppO2 (Partial Pressure Oxygen), using the hand-held CSA-O2 (Compound Specific Analyzer-Oxygen) sensors that were readjusted on 1/22. Batteries were to be replaced if necessary. (CSA- O2s #1041 & #1052 were to be activated (if not already on) for taking readings in the Lab. Afterwards, both units were to be turned off and returned to their stowage. Purpose of the 15-min activity is to trend with MCA (Major Constituents Analyzer), i.e., to correlate the hand-held readings with MCA measurements, prior to US EVA-14 scheduled for next Wednesday. Daily CSA- O2 readings will be compared to the MCA to ensure the hardware is operating to a known calibrated device. Two CSA- O2s are required to support the Airlock campout for the upcoming US EVA-14.)

At the HRF1 (Human Research Facility 1) rack, Tani deactivated the MedOps cardiac defibrillator and conducted its periodic checkout, which was to be recorded on video and later dumped to the ground (Last time done: 12/4/07). (This routine maintenance task is scheduled as soon as possible from Expedition start and every 60 days thereafter. For the checkout, the defib is connected to the 120V outlet, equipped with its battery (today #1020) and then allowed to charge, for about five seconds, to a preset energy level (e.g., 100 joules). After the button-triggered discharge, a console indicator signals success or failure of the test. The pacing signal is downlinked via S-band for 1 min. The HRF was powered down afterwards.)

Dan completed today's routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables.

The FE-1 performed the daily 20-min. IMS 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).

The FE-2 set up the video configuration for the upcoming weekend Robotics operations by putting in place the necessary cable hook-up of the UOP DCP (utility outlet panel/display & control panel) power bypass cable at the CUP RWS (Cupola Robotic Work Station).

The crewmembers performed 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-2) and VELO bike with bungee cord load trainer (FE-1).

Afterwards, Tani copied the exercise data file to the MEC (Medical Equipment Computer) laptop for downlink, including 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 ~9:25am EST, the CDR and FE-2 supported an interactive PAO interview with Cathi Erdman of the Chicago Daily Herald.

Robotics & SARJ Preview: Tomorrow, 1/25, the SSRMS (Space Station Remote Manipulator System), currently based on Node-2, will be 'walked off' inchworm-style to the MT MBS (Mobile Transporter/Mobile Base System), detached from Node-2 and re-based on MBS PDGF-1 (Power & Data Grapple Fixture 1). On 1/26-27, the SSRMS will be maneuvered to the subsequently planned Stbd SARJ (Solar Alpha Rotary Joint) inspection via ground control. On Saturday, SSRMS will inspect the race ring's outer canted surface, while on Sunday the survey will focus on the Datum A surface. During each inspection, the SARJ will be rotated using 12 degree directed positioning moves every 5 minutes (requires 8 orbits for a full 360 degree inspection). Meanwhile, ground analysis of the root cause continues. Power analyses for upcoming missions are scheduled to be completed over the next month. SARJ cleaning and lubrication techniques are being evaluated. A grease gun will be added to 1E manifest. ULF-2 manifest will likely have 12 TBAs (Trundle Bearing Assemblies) and 1 DLA (Drive Lock Assembly). Increment 18 and ULF-2 crew will receive training on outboard mode R&R and SARJ cleaning operations.

Progress 26P Reentry: On 1/22, 26P completed its deorbit burn and destructive reentry into the Earth's atmosphere. The 83.16 m/s deorbit burn began at approximately 2:06 pm EST and lasted for 2 minutes and 24 seconds. 26P undocked from the DC1 (Docking Compartment) nadir port on 12/21/07 to make room for 27P.

CEO (Crew Earth Observation) photo targets uplinked for today were Canberra, Australia (weather was predicted to be mostly clear over the capital city of Australia. The nadir pass provided an opportunity to acquire a SW to NE transect across the metropolitan area. Nadir imagery of the rural-urban fringe transition zones is of particular interest), Sydney, Australia (shortly after leaving Canberra, ISS orbit track brought the crew over the most populous city in Australia - Sydney. Similarly to the Canberra target, a nadir image transect across the metropolitan area and into the harbor was requested), and Lake Eyre, Australia (looking to the right of track for Lake Eyre, a large and mostly dry lake bed in south-central Australia. General context views using the short lens were requested to capture the entire lake area. This will augment higher resolution images of the lake that the crew acquired earlier in this Expedition).
