Mission 1E Flight Day 7 (FD7).

Crew sleep cycle remains at 4:45am EST - 8:15pm for both crews.

Mission 1E's EVA-2 was completed successfully by Rex Walheim & Hans Schlegel in 6h 45m, accomplishing all its objectives and get-aheads.
(During the spacewalk, Walheim (EV1) & Schlegel (EV2) removed the new NTA (Nitrogen Tank Assembly) from the Shuttle PLB (Payload Bay), 'flew' it to the CETA (Crew & Equipment Translation Aid) cart for transfer to the P1 truss, installed it in place of the failed NTA, which they returned via CETA for stowage in the PLB, and performed Get-Aheads, viz.: Clean up Lab MMOD (Micrometeoroid/Orbital Debris Shield) & install Columbus Trunnion Covers.) Official start time of the spacewalk was 9:27am EST, about 8 min ahead of the timeline, and it ended at 4:12pm. Total EVA duration (PET = Phase Elapsed Time) was 6h 45min. It was the 103rd spacewalk for ISS assembly & maintenance and the 75th from the station (28 from Shuttle, 53 from Quest, 22 from Pirs) totaling 457h 56min, and the 7th for Expedition 16 (totaling 50h 04min). After today's EVA, a total of 127 spacewalkers (95 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 646h 18min outside the station on building, outfitting and servicing. It was also the 125th spacewalk involving U.S. astronauts.)

Final COL (Columbus Orbital Laboratory) activation procedures were put on hold for today due to an onboard computer issue between a C&C MDM (Command & Control Multiplexer/Demultiplexer) computer and the MMC (Mission Management Computer). (Clearing the command queue in the CCS (Command & Control System) memory, blocked by a bit that erroneously indicates the queue to be empty, is requiring MCC-Houston to create, test, uplink and execute a special command sequence 'from scratch'.)

To establish ventilation allowing crew activities inside COL, COL-CC (Columbus Control Center) in Oberpfaffenhofen attempted a workaround by uplinking commands via VTC (Vital Telemetry Telecommand Computer) to cycle COL IMV (Intermodular Ventilation) valves and turn on the IRFA (IMV Return Fan Assembly), establishing module ventilation. The attempt was not satisfactory. At this time, there is no IMV, and smoke detection, dependent on ventilation, is currently prime crew responsibility.

COL activation operations, on hold due to the CCS command issue, will deal mostly with moving European payload systems from their launch locations and setting them up at their operational rack positions. The work ahead by FE-2 Dan Tani & FE-2-16 Leo Eyharts is to include among else -

Installing K-BAR capture mechanisms in COL and relocating a ZSR (Zero-G Stowage Rack) and its pivot fittings from position A2 to O3 (or F3 to O4) in COL,
Rotating COL Rack D1 forward (away from the cell wall),
Installing RPDA (Remote Power Distribution Assembly) items and a front panel on the Biolab (BLB),
Relocating the BLB to its ISPR (International Standard Payload Rack) location & installing its DC converter,
Tilting the D1 rack back and securing it,
Relocating the EDR (European Drawer Rack) to its final ISPR position,
Activating the PWS (Portable Workstation) in COL, and
Setting up PCS (Portable Computer System).
(Biolab (Biological Experiment Laboratory in Columbus) is a biological and physiological facility for studying the effects of microgravity on microorganisms, cells, tissue cultures, small plants and small invertebrates. EDR is a multi-discipline facility that provides an opportunity for compact experiments of low mass, supporting a variety of small payloads. Each payload will have access to power, data communications, cooling among other accommodations.)

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.)

As part of pre-EVA activities, Dan Tani closed the protective Lab science window shutters, while Yuri Malenchenko powered down the ham radio equipment in SM (Service Module) and FGB at ~6:30am EST to prevent RF interference with the EMUs during the spacewalk.

The FE-2 performed the periodic offloading of the Lab CCAA (Common Cabin Air Assembly) dehumidifier's condensate tank, filling CWC (Contingency Water Container) #1062 with the collected water slated for processing. No samples required this time. (Estimated offload time before termination (leaving ~6 kg in the tank): ~25 min.)

Malenchenko used the standard pump/hose gear to collected a water sample of ~200 mL from the SM BV1 Rodnik storage tank for return to Earth.

Afterwards, the FE-1 activated the Russian KTsP2 (Central Post Computer 2) RS2 laptop with its new display software, installed yesterday, for backup, before working on the KTsP1 RS3 laptop to repeat the software upgrade from a flash drive, then making a backup copy.

Yuri also conducted the periodic (currently daily) checkout/verification of IP-1 airflow sensors in the various RS (Russian segment) hatch openings (8) in the SM, FGB and DC1 (Docking Compartment).

Later, Malenchenko transferred the ATV (Automated Transfer Vehicle) control panel (PU) to its operational location and installed it.

The FE-1 continued his work with the Russian KPT-2 science payload BAR-RM, Kelvin, Ira and TTM, begun yesterday, today running tests and taking the first measurements (temperatures, relative humidity, dew point temperatures), using the RSK1 laptop (which he reconfigured afterwards). The data are being used for experimenting with ISS leak detection based on environmental data anomalies (temperature, humidity, and ultrasound emissions) at leak locations. After the data gathering, downlinking was via BSR-TM channel. (BAR-RM is designed to develop a procedure for detection of air leakage from ISS modules based on environmental data anomalies (temperature, humidity, ultrasound emissions). The payload uses a remote infrared thermometer (Kelvin-Video), a thermohygrometer (Iva-6A), a heat-loss anemometer/thermometer (TTM-2), an ultrasound analyzer (AU-01), and a leak detector (UT2-03) to determine physical background signs of loss of ISS pressure integrity which could be indicative of leaks in the working compartments of the station. Measurements are taken in specific zones (13 in SM PkhO and 4 in DC1), both with lights & fans turned on and off.)

During today's spacewalk by Rex & Hans, PLT Alan Poindexter provided IVA support, while MS1 Leland Melvin and MS4/EV3 Stan Love worked the SSRMS (Space Station Remote Manipulator System) to assist with the NTA R&R (Removal & Replacement).

After the spacewalkers' ingress at 4:12pm, post-EVA activities by CDR Steve Frick, CDR Peggy Whitson, Schlegel and Walheim in the Joint Airlock (A/L) consisted of recharging the EMU/spacesuits with water from PWR (Payload Water Reservoir), then reconnecting the LTAs (Lower Torso Assemblies) to the EMUs and capping the UIA (Umbilical Interface Assembly), initiating and monitoring the regeneration of the METOX (Metal Oxide) CO2 filter canisters, initiating the discharge/recharge process on the EMU batteries in the BSA (Battery Stowage Assembly), and reconfiguring EVA tools.

In preparation for upcoming experiment activities, FE-1 Yuri Malenchenko continued the current extended performance check of the Russian KRIOGEM-03M refrigerator system, powered up yesterday to -22 degC with an AX ice pack from storage installed, for once-daily monitoring of its displayed temperature for the next five days (through 2/17).

Yuri also completed the routine servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM). (Regular daily SOZh maintenance consists, among else, of checking the ASU toilet facilities, replacement of the KTO & KBO solid waste containers and replacement of EDV-SV waste water and EDV-U urine containers.)

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

Other voluntary items on Yuri's 'job jar' list for today were -

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 BIO-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.), and
The regular checkup on the Japanese experiment GCF-JAXA (Granada Crystallization Facility) in the Russian TBU incubator, maintained at +20 degC, including a temperature check on its ART (automatic temperature recorder). (This is a daily monitoring/temp checking, carried on the Russian voluntary task list for the duration of Expedition 16.)
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).

Malenchenko later 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).

ETCS Shutdown: Loop A of the ISS ETCS (External Thermal Control System) suffered an inadvertent shutdown yesterday afternoon after the begin of COL MTL IFHX (Moderate Temperature Loop Interface Heat Exchanger) integration into the ETCS Loop A. The shutdown occurred when the loop's flow control valve was unable to compensate for a warm (~65 degC) slug of ammonia passing through the system from the first IFHX that was discovered to have been left powered on (to provide extra margin against freezing). After recovery of the ETCS loop per procedure, the heater was deactivated and both COL IFHXs were integrated without further incident.
