Ahead: Week 13 of Increment 16.
CDR Whitson & FE-2 Tani started out with the daily reading of SLEEP (Sleep-Wake Actigraphy & 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.)
FE-1 Malenchenko prepared for today's last day of his five-day wearing test of the spring-loaded 'Penguin-3' antigravity pressure/stress suit with its load measuring system (SIN), donning the suit and its equipment, then going about his business and downloading performance measurements several times. (Each day, Yuri has selected higher symmetrical (shoulders) & asymmetrical (chest & back) loads (~20-30 kgf), after calibrating the system with no load on the suit's internal tension straps. Load data are then collected by the SIN electronics (via analog-to-digital converters) and downloaded to a A31p laptop three times daily, followed by downlink to the ground via BSR-TM.)
FE-2 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.)
Malenchenko completed today's routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM), including ASU toilet facilities systems/replaceables, the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP.
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).
The CDR and FE-2 each had their 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), Dan at ~9:05am EST, Peggy at ~12:00pm.
Working off his discretionary 'time permitting' task list, Yuri conducted another session of the Russian "Uragan" (hurricane) earth-imaging program, using the Nikon D2X digital camera with 800 mm focal length lens. (Targets uplinked for today were Patagonia Glaciers and Icebergs in the Drake Passage.)
A second job item on the FE-1's voluntary list for today was another KPT-3 session to make observations and take aerial KPT-3 photography of environmental conditions for Russia's Environmental Safety Agency (ECON) using the Nikon D2X digital camera with SIGMA 300-800mm telephoto lens.
Task items on Peggy's and Dan's discretionary 'job jar' task list today were (1) a thorough review of uplinked draft material on the BMRRM (Bearing Motor Roll Ring Module) hardware and EVA-14 procedures for its upcoming R&R, (2) an audit of CTB (Cargo Transport Bags) and their contents, and (3) installation of a ground wire on the PFA (Portable Fan Assembly).
No CEO photo targets uplinked for today.
