Progress M-63/28P is continuing its 3-day flight to the ISS for docking tomorrow morning (2/7) at ~9:38am EST at the DC1 nadir port.

After wakeup and before breakfast, FE-2 Dan Tani completed his daily access of the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for downlink. (To monitor the crewmember's 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 began Part 1 (of 5) of the periodic acoustic measurement protocol by deploying crew-worn acoustic dosimeters, to be carried for 24 hours (with a microphone on the shirt collar). (Last time done: 12/26). (Tonight, after about 15 hours of measurements, dosimeter data will be downloaded and the hardware power-cycled for another data take starting tonight after 8.5-hr. sleep. At that point, the crew will deploy the dosimeters statically in the station for the duration of the day, record measurements tomorrow noon and stow the instruments. Acoustic data must be taken twice per Increment, each time for the duration of the 16-hour crew workday.)

Before breakfast and exercise, FE-1 Malenchenko completed his second session with the periodic Russian MedOps test "Hematokrit" (MO-10), measuring red cell count of the blood. (The blood samples were drawn from a finger with a perforator lancet, then centrifuged in two microcapillary tubes in the M-1100 kit's minicentrifuge, and its hematocrit value was read off the tubes with a magnifying glass. It is a well-known phenomenon of space flight that red blood cell count (normal range: 30-45%) tends to go down over time. After the exam, the data were saved in the IFEP software (In-Flight Examination Program) on the MEC (Medical Equipment Computer), and Oleg Kotov stowed the equipment.)

Also upon wakeup, Malenchenko terminated his ninth MBI-12 SONOKARD experiment session, started last night, 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. (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.)

All three crewmembers participated in the periodic training exercise for emergency response to fire on-board the ISS. Today the emergency simulation was a burning odor in Node 1. A conference between the crew and ground specialists was held after the simulation to assess the training exercise.

CDR Whitson and FE-1 Yuri Malenchenko conducted a TV downlink test via Ku-band. The purpose of this test was to convert the Russian video signal into a National Television Standards Committee (NTSC) video signal for downlink via Ku-Band, as well as Motion Picture Expert Group (MPEG)-2 streaming video via Operations Local Area Network (OPS LAN). This procedure can be used during Soyuz, Progress, and Automated Transfer Vehicle (ATV) dockings or Russian-based Extravehicular Activities (EVAs). The test was nominal.

Whitson and FE-2 Dan Tani worked in the U.S. Airlock (A/L), successfully completing numerous EVA hardware configuration activities. (Peggy and Dan reconfigured EMU 3018 for use by Stan Love during Flight 1E and configured EMUs 3006 and 3008 for Flight 1J/A. Tani also gathered US EVA tools, reprogrammed PGTs (Pistol Grip Tools), and checked out two SAFER (Simplified Aid for EVA Rescue) units. These activities were all in support of Flight 1E. In addition to EMU resizing, the CDR initiated an EMU battery discharge cycle to completely discharge EMU battery 2041. Completely discharging this battery will maximize its effectiveness in supporting EVAs during Flight 1J/A.)

Using the vacuum cleaner and other tools, the FE-2 performed the periodic 80-min US segment (USOS) hatch seal inspection (Node-1 forward, aft & starboard, Lab aft & forward, Node-2 aft, and Joint Airlock) in support of ACS (Atmospheric Control System) maintenance (last time done: 11/17).

Continuing his support of the NUTRITION experiment, Dan Tani collected urine samples for the Repository payload. (Repository utilizes a storage bank to maintain biological specimens over extended periods of time and under well-controlled conditions. Samples from ISS crewmembers, which include blood and urine, are collected, processed, and archived during the preflight, inflight, and postflight phases of ISS missions. These biosamples will serve as a resource for future spaceflight-related medical research.)

CDR Whitson completed T+2 in-flight microbiology analysis of water samples she collected in MCDs (Microbial Capture Devices) on 2/4. (The water samples were taken from the SM SRV-K (Service Module/Condensate Water Processor) Hot and Warm water taps. Some of the samples taken on 2/4 will return on Flight 1E for ground analysis.)

Last night, when TsUP-Moscow performed a TORU system test on the SM, it failed, showing zero output voltage on the primary VHF receiver. During the next ground pass (Daily Orbit 4), when the output voltage was still 0 on the primary VHF receiver, Moscow switched to the backup VHF receiver, on which it was nominal. The TORU system test was nominal on the backup VHF receiver. (TORU is still available for docking, but now zero-fault tolerant. Per Flight Rules D2-8 para. D, D2-10 para. B.2 docking is still possible since the Kurs system is available. Since TORU is a backup to KURS and is only used if the crew needs to perform manual docking, Progress 28P is still GO for docking tomorrow morning at ~9:38am EST.).

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

Whitson 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).
