Happy Birthday, Dan!

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 wears 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.)

Before breakfast, CDR Whitson completed her 120-Day NUTRITION/w Repository session (blood collection only). Whitson also set up NUTRITION w/Repository hardware for the 24-hour urine sample collections that will begin tomorrow morning and end Sunday morning.

Also before breakfast, CDR Whitson, FE-1 Malenchenko and FE-2 Tani started the day with the periodic session of the Russian biomedical routine assessments PZEh-MO-7/Calf Volume Measurement and PZEh-MO-8/Body Mass Measurement (third for CDR & FE-1, second for FE-2), using the IM mass measurement device which Yuri Malenchenko afterwards broke down for stowage. (Calf measurements (left leg only) are taken with the IZOG device, a custom-sewn fabric cuff that fits over the calf, using the knee and lower foot as fixed reference pints, to provide a rough index of deconditioning in zero-G and effectiveness of countermeasures. For determining body mass in zero-G, where things are weightless but not massless, the Russian IM "scales" measure the inertial forces that arise during the oscillatory motion of a mass driven by two helical metering springs with known spring constants. By measuring the time period of each oscillation of the unknown mass (the crewmember) and comparing it to the period of a known mass, the crewmember's mass is calculated by the computer and displayed.)

FE-2 Dan Tani assisted ground controllers in MCC-Houston by successfully walking the SSRMS (Space Station Remote Manipulator System) from the MBS (Mobile Base System to the Node-2 PDGF (Power & Data Grapple Fixture. (The SSRMS is now in the 1E start position. Robotics ground controllers also translated the MT from WS4 (Worksite 4) to the WS7 for Flight 1E. The MT translation was successful, but only one of two IMCA (Integrated Motor/Controller Assembly) 'ready for latch' microswitches on the primary string showed ready for latching at WS7. Ground controllers switched to the redundant string and both microswitches on that string showed ready for latching, then switched back to the primary string and both microswitches showed ready for latching at that time. The MT was successfully latched at WS7 and keep alive power was restored to the MBS. The MT will be translated back to WS4 after Flight 1E.)

FE-1 Yuri Malenchenko and CDR Whitson installed the Docking Mechanism (StM) between Progress M-62/27P and the DC1 nadir port. (The StM is the "classic" probe-and-cone type, consisting of an active docking assembly (ASA) with a probe (SSh), which fits into the cone (SK) on the passive docking assembly (PSA) for initial soft dock and subsequent retraction to hard dock. The ASA is mounted on the Progress' cargo module (GrO), while the PSA sits on the docking ports of the SM, FGB and DC1.)

Malenchenko and Whitson also conducted another TORU OBT (Tele-operator Control System On-Board Training) session in preparation for the docking of 28P on (The TORU training session consisted of procedure and docking data reviews, a tagup with ground instructors, and onboard simulator training. 27P will undock from ISS on 2/4 (5:27am EST). 28P will dock to ISS on 2/7 (9:38am EST).)

Tani completed various EVA equipment preparation and reconfiguration tasks today, including EMU (Extravehicular Mobility Unit) water refills and cooling loop scrubs, cooling loop configurations, and METOX (Metal Oxide) regeneration operations. (EVA Postscript: It was reported that during the Airlock (A/L) hatch closing at the end of EVA-14, a tether was caught in the hatch requiring the hatch to be re-opened to remove the tether before re-closing. Ground specialists speculated that the tether might have damaged the hatch seal due to this event. Further review has determined the part of the tether caught in the hatch was Nomex cloth which would not have damaged the A/L hatch seal. Additionally, positive indication of seal integrity was provided by the leak check during A/L repressurization. No further analysis is planned at this time.)

TsUP-Moscow conducted a successful retest of the Medium Gain-2 (WAS2) antenna as part of the PCE (Proximity Communication Equipment) checkout required for ATV-1 (Automated Transfer Vehicle 1) rendezvous and docking. (The retest required an attitude control handover from USOS (US Segment) momentum management control to RS (Russian Segment) thruster control (~11:50am EST) and back (~2:35pm). The attitude for the test was LVLH (Local Vertical/Local Horizontal) 0, 0, 0. TsUP specialists indicated the WAS2 antenna passed today's test.)

Peggy worked with the DCS-760 still cameras, taking blank and white images to 'clean' and calibrate the CCDs (Charge-Coupled Devices). The test photos were stored on a 1GB Microdrive PCMCIA and downlinked to MCC-Houston for determining which cameras will be used for the actual RPM activities before STS-122/1E docking.

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

Working off his discretionary 'time permitting' task list, the FE-1 also 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).

At ~3:35am EST, the crew held the regular (nominally weekly) tagup with the Russian Flight Control Team (GOGU), including Shift Flight Director (SRP), at TsUP via S-band/audio, phone-patched from Houston and Moscow.

At ~9:20am, the station residents convened for their weekly teleconference with ISS Program Management at JSC/Houston via S-band/audio.

At ~2:40pm, the crew was scheduled for their eighth weekly tagup with the Lead Flight Director at JSC/MCC-H via S-band/audio. (S/G-2 (Space-to-Ground 2) phone patch via SSC-10 (Station Support Computer 10)).

The crewmembers completed 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), TVIS treadmill (FE-1, FE-2), RED resistive exercise device (CDR, FE-2), and VELO bike with bungee cord load trainer (FE-1).

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