Ahead: Week 16 of Increment 16.
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 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.)
Upon wakeup, CDR Whitson performed another urine collection for the NASA/JSC experiment NUTRITION w/Repository, collecting a final urine sample for storage in the MELFI (Minus-Eighty Laboratory Freezer for ISS), after which the experiment was turned off. The next urine collection closed out with the first void of today. Peggy's next Nutrition/Repository activity is the FD180 session. (The current NUTRITION project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight. It includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes, expanding the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)
For today's VolSci (Voluntary Weekend Science) program, CDR Whitson continued her work with the MSG (Microgravity Science Glovebox) and the InSPACE-2 (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment,
FE-2 Dan Tani's VolSci program for today consisted of another session (the fourth) of the LOCAD-PTS (Lab-on-a-Chip Application Development-Portable Test System)/Phase 2 operations, sampling four of the sites that were identified in the CHeCS SSK (Crew Health Care Systems/Surface Sampler Kit) procedure also scheduled for today. (The goal is to compare LOCAD results with the SSK colony growth results. LOCAD uses small, thumb-sized 'microfluidic' cartridges that are read by the experiment reader. The cartridges contain dried extract of horseshoe crab blood cells and colorless dye. In the presence of the bacteria, the dried extract reacts strongly to turn the dye a green color. Therefore, the more green dye, the more microorganisms there are in the original sample. The handheld device tests this new analysis technology by sampling for the presence of gram negative bacteria in the sample in about 15 minutes, showing the results on a display screen. Background: Lab-on-a-Chip technology has an ever-expanding range of applications in the biotech industry. Chips are available (or in development) which can also detect yeast, mold, and gram positive bacteria, identify environmental contaminants, and perform quick health diagnostics in medical clinics. The technology has been used to swab the MERs (Mars Exploration Rovers) for planetary protection. With expanded testing on ISS, began by Sunita Williams in March/April this year, this compact technology has broad potential applications in space exploration--from monitoring environmental conditions to monitoring crew health. The current study should prepare for long-duration exploration by demonstrating a system that enables the crew to perform biochemical analysis in space without having to return samples to Earth.)
After Houston Flight Controllers started deactivating the CDRA (Carbon Dioxide Removal Assembly) early this morning and cooling was no longer required, the FE-2 disconnected the ITCS LTL QD (Internal Thermal Control System/Low Temperature Loop/Quick Disconnect) jumper to the CDRA rack (LAB1D6).
The FE-1 completed the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables plus the weekly collection of the toilet flush counter (SPK-U) and water supply (SVO) readings for calldown to TsUP/Moscow.
Malenchenko 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.
Whitson and Tani had their weekly PFCs (Private Family Conferences) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on the SSC-9 laptop), Peggy at ~10:00am EST, Dan at ~11:25am.
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 (FE-2), TVIS treadmill (CDR, FE-1), RED resistive exercise device (CDR, FE-2), and VELO bike with bungee cord load trainer (FE-1).
Working off his 'time permitting' discretionary task list, Yuri conducted his sixth run of the Russian DZZ-2 "Diatomeya" ocean observations program, using the NIKON-F5 still camera with 80-200 mm Nikkor zoom lens and the SONY PD-150O camcorder to record color contrasts on water surface and irregular cloud cover pattern in the World Ocean target areas. (Uplinked target zones in the Atlantic Ocean were offshore areas of Argentina, the Gulf of Guinea and the coastal area of Northwest Africa, the Amazon river runoff area and the Madeira Islands water region.)
Also from his discretionary 'time permitting' task list, Malenchenko used the updated Symantec AntiVirus program to run a check on the RSS2 laptop and download data logs.
On Dan Tani's 'job jar' task list for today was to fill out an uplinked questionnaire on the post-EVA condition of the EMU overgloves.
No CEO photo targets uplinked for today.
