Ahead: Week 9 of Increment 17.
First activity this morning for Gregory Chamitoff was to start on his Flight Day 15 session with the NASA/JSC experiment NUTRITION w/Repository. This is an all-day session, the first for Greg, of collecting urine samples several times for 24 hrs, to continue through first void tomorrow morning.
Oleg Kononenko conducted the routine daily servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM), including the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP-Moscow. (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.)
The FE-1 also gathered weekly data on Total Operating Time & 'On' durations of the Russian POTOK-150MK (150 micron) air filter unit of the SM's SOGS air revitalization subsystem for reporting to TsUP.
For Sergey Volkov, today's Russian discretionary task list held one job - continuing the GFI-8 "Uragan" (hurricane) earth-imaging session begun two days ago, using the D2X digital camera with the F800 telephoto lens. (Uplinked target areas were the forest cover on mountain slopes on the north shore of Lake Sevan, drilling platforms near the western shores & on the eastern shores of the Caspian Sea, the coastal strip of the Aral Sea (overlapping frames), the Katun river valley in nadir & to the right of track, the Eastern shores of Lake Teletsk, the forest condition in the Sayan mountains, the northern shore of Lake Baikal, wooded areas in Greece, the Danube river valley all the way to the estuary, scenic photography of the Crimea from different points on orbit, the Kerch Strait, the Don river valley, conditions of the Volga-Akhtubinsk flood plain during water reservoir releases, drill well fields along & to the south of Ural river, general views of the Pyrenees, of the Alps and the Carpathian mountains from various points on orbit, the Oka river and Don river valleys, and the valley of any other river between Don and Volga.)
Also working from the 'if time permits' task list, the CDR conducted another run, his fifth, of the Russian DZZ-2 "Diatomeya" ocean observations program, using the NIKON-F5 DCS still camera and the HDV (high-definition) video camcorder from SM window 8 for ~20 min to record high production water areas for obtaining data on color field composition in dynamic regions of the ocean and in near-estuary areas of large rivers, plus the current cloud cover above these waters, its rating, and special forms of cloud formation. (Target zones today were in the Atlantic Ocean (Cape Hatteras & English Channel).)
For the FE-1, a discretionary task list job was another session for Russia's Environmental Safety Agency (EKON), making observations and taking KPT-3 aerial photography of environmental conditions of water contamination in the Kerch Strait using the Nikon D2X with the SIGMA 300-800mm telephoto lens.
At ~5:00pm EDT, Greg Chamitoff 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 an SSC laptop).
The three crewmembers conducted their regular 2.5-hr. physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the TVIS treadmill (CDR, FE-1, FE-2), RED resistive exercise device (CDR, FE-1, FE-2), and VELO bike with bungee cord load trainer (CDR, FE-1).
No CEO (Crew Earth Observation) photo targets uplinked for today.
