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.)

Peggy Whitson continued her work with the InSPACE-2 (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment in the MSG (Microgravity Science Glovebox), today conducting runs #23 and #24, then powering down the payload and switching the MSG to standby. (After activation of MSG plus InSPACE & InSPACE-2 equipment, Peggy checked on alignment & focusing of MSG video cam #2, repositioned the sample vial, changed out video recorder tapes and later deactivated InSPACE & MSG. InSPACE, conducted last in June 2006 by Jeff Williams on Increment 13, obtains basic data on magnetorheological fluids, i.e., a new class of "smart materials" that can be used to improve or develop new brake systems, seat suspensions robotics, clutches, airplane landing gear, and vibration damper systems. The dispersed particles are contained in CAs (Coil Assemblies) in the MSG that subject them to electric fields of certain strength and frequencies.)

FE-1 Malenchenko supported TsUP-Moscow in the third of four days of ASN-M Satellite Navigation System testing. (Today's activities by Yuri consisted in transferring raw ASN date from yesterday's ATV (Automated Transfer Vehicle) approach rehearsals from Laptop3 to PCMCIA memory card and setting it up for data downlinking to TsUP for analysis and determination how the test is proceeding. The purpose of the week long testing is to confirm ASN-M hardware readiness for the upcoming ATV 'Jules Verne' vehicle docking.)

Dan Tani performed his daily status check on the BCAT-3 (Binary Colloidal Alloy Test-3) science payload, running by itself in Node-2 since 12/13/07 (briefly interrupted for EVA-13 photo support). (The status check, conducted on the last image taken by the DCS 760 digital still camera which is controlled by EarthKAM software on an A31p laptop, is to verify proper image focus and camera alignment. The SSC (Station Support Computer) is taking photography of the phase separation occurring in the BCAT Sample 3, with the photo flash going off every half hour.)

Dan also relocated the IVCPDS/TEPC (Intravehicular Charged Particle Directional Spectrometer/Tissue Equivalent Proportional Counter), the primary radiation measurement tool in the ISS, from Node-2, where it was positioned on 12/24/07, to the Service Module (SM) on panel 410, plugging its power/data cable into the CHeCS (Crew Health Care Systems) outlet 1 on SM panel 210.

FE-1 Yuri Malenchenko underwent the periodic (generally monthly) health test with the cardiological experiment PZEh MO-1 ('Study of the Bioelectric Activity of the Heart at Rest') on the TVIS (Treadmill with Vibration Isolation System). (During the 45-min. test, the FE-1 tagged up with ground specialists on a Russian ground site (RGS) pass via VHF and downlinked data from the Gamma-1M ECG (electrocardiograph) for about 5-6 minutes.)

The FE-2 took air samples for the periodic (weekly) atmospheric status check for ppO2 (Partial Pressure Oxygen), using the hand-held CSA-O2 (Compound Specific Analyzer-Oxygen) sensors. 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.)

After printing out newly uplinked procedures for the US EVA-14 next week (1/30), the CDR & FE-2 conducted a two-hour review of the briefing package, covering topics like egress plan, timeline ordering of tasks, translation/fairleads/tether plan, hazards, and ingress plan. Later (~9:10am EST), Peggy and Dan tagged up with ground specialists to discuss particulars. Using the crew input, final procedures are now being prepared. (The spacewalk of ~6 hrs duration has one major objective, broken into several steps: (1) Set up BMRMM (Bearing Motor Roll Ring Module, 'broom') worksite; (2) Removed failed BMRRM (~35 min); (3) Install replacement BMRRM (~35 min); (4) Clean up worksite; and (5) Inspect STBD SARJ (Solar Alpha Rotary Joint).)

In the U.S. Airlock, Whitson initiated charging EMU (Extravehicular Mobility Unit) batteries in the BCA (Battery Charger Assembly).

Malenchenko again had several hours for cargo transfers from Progress M-62/27P to the ISS and stowing trash on the drone spacecraft for disposal (2/4), tracking movements in the IMS (Inventory Management System).

The FE-1 completed today's routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables.

Yuri also conducted 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).

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

Dr. Whitson broke out and set up the PFE-OUM (PFE-Oxygen Uptake Measurement) equipment on the HRF-2 (Human Research Facility 2) rack, including the HRF PFM/PAM (Pulmonary Function Module/Photoacoustic Analyzer Module), Mixing Bag System and GDS (Gas Delivery System). Data collection on herself and Dan, taking turns, is scheduled tomorrow. (The Periodic Fitness Evaluation with Oxygen Uptake Measurement experiment, using the CEVIS ergometer for workout, demonstrates the capability of crewmembers to perform periodic fitness evaluations with continuous oxygen consumption measurements within 14 days after arrival on ISS, and once monthly during routine PFEs. Once the capability of the pulmonary function system (PFS) to perform PFEs is verified, crewmembers will be able to integrate their monthly PFE with oxygen consumption measurements to fulfill the requirement for cardiovascular fitness evaluations during long-duration space flight.)

Working off his discretionary 'time permitting' task list, Yuri performed the daily monitoring and picture-taking 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 will be receiving photo images taken by Yuri.)

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 (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 ~11:25am EST, the CDR and FE-2 supported an interactive PAO interview with students, teachers, administrators and guests of Anderson Elementary School in Wichita, KS, gathered at the Exploration Place in Wichita.

At ~2:05pm, Dan 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 the SSC-10 laptop).

Robotics Preview: On 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.

CEO (Crew Earth Observation) photo targets uplinked for today were Heard Island, S. Indian Ocean (a clear weather window is predicted to be present in the region of Heard Island at the time of the ISS pass. Looking to the right of track as the station approached Antarctica. Mapping photography of the island was requested to capture snow and ice extent), S. Georgia/S. Sandwich, S. Atlantic Ocean (weather was predicted to be clear over these South Atlantic islands during the ISS pass. Looking to the right of track for the islands. Mapping photography of snow and ice on the islands was requested. There may also have been sea ice visible to the S-SW of the island for photography, including a large iceberg (A53A)), and Patagonian Glaciers, S. America (ISS track provided a traverse across the northern portion of the Patagonian ranges. Overlapping, nadir mapping frames of summit glaciers and icefields, taken along track, were requested).
