All ISS systems continue to function nominally, except those noted previously or below. Saturday - mostly off duty for CDR Volkov, FE-1 Kononenko & FE-2 Chamitoff.
The crew performed the regular weekly three-hour task of thorough station cleaning. ["Uborka", usually done on Saturdays, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the SM (Service Module) dining table, other frequently touched surfaces and surfaces where trash is collected, as well as the FE's sleep station with a standard cleaning solution; also, fan screens and grilles are cleaned to avoid temperature rises. Special cleaning is also done every 90 days on the HEPA (high-efficiency particulate air) bacteria filters in the Lab.]
As part of the house cleaning, the crew also conducted regular maintenance inspection & cleaning on fan grilles in the FGB (TsV2) and SM (VPkhO, VPrK) plus in the COL (Columbus Orbital Laboratory).
For today's VolSci (Voluntary Weekend Science) program, another session with SHERE (Shear History Extensional Rheology Experiment), FE-2 Chamitoff -
[Background: Rheology is the study of the deformation and flow of matter under the influence of an applied stress which might be, for example, a shear stress or extensional stress. In practice, rheology is principally concerned with extending the "classical" disciplines of elasticity and (Newtonian) fluid mechanics to materials whose mechanical behavior cannot be described with the classical theories. SHERE is designed to study the effect of preshear on the transient evolution of the microstructure and viscoelastic tensile stresses for monodisperse dilute polymer solutions in the MSG. Collectively referred to as "Boger fluids," these polymer solutions have become a popular choice for rheological studies of non-Newtonian fluids and are the non-Newtonian fluid used in this experiment. The SHERE hardware consists of the Rheometer, Camera Arm, Interface Box, Cabling, Keyboard, Tool Box, Fluid Modules, and Stowage Tray.]
The FE-2 performed another standard calibration on the new CSA-O2 (Compound Specific Analyzer-Oxygen) units #1043 & #1059, delivered on 1J.
Supporting ground-commanded commissioning preparations in the JAXA Kibo JPM (JEM Pressurized Module), Gregory turned off power output from the Saibo & Ryutai Rack UDCs (Utility DC-to-DC Converters) to the MMA NCU & RSUs (Microgravity Measurement Apparatus/Network Control Unit & Remote Sensor Units), then deactivated the NCU/RSUs themselves.
FE-1 Kononenko completed the routine daily servicing of the SM's SOZh system (Environment Control & Life Support System, ECLSS). [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-2 took measurements for the regular atmospheric status check for ppCO2 (Carbon Dioxide partial pressure) in the Lab, SM (at panel 449) and COL, using the hand-held CDMK (CO2 Monitoring Kit, #1002). [The battery pack was to be replaced with the one from unit #1009 if necessary. Purpose of the 5-min activity is to trend with MCA (Major Constituents Analyzer), i.e., to correlate the hand-held readings with MCA measurements. Greg's CDMK reading in the SM was 0.49; in Lab 0.46, and in COL 0.50.]
Gregory also filled out the regular FFQ (Food Frequency Questionnaire), his ninth, on the MEC (Medical Equipment Computer). [On the FFQs, NASA astronauts keep a personalized log of their nutritional intake over time on special MEC software. Recorded are the amounts consumed during the past week of such food items as beverages, cereals, grains, eggs, breads, snacks, sweets, fruit, beans, soup, vegetables, dairy, fish, meat, chicken, sauces & spreads, and vitamins. The FFQ is performed once a week to estimate nutrient intake from the previous week and to give recommendations to ground specialists that help maintain optimal crew health. Weekly estimation has been verified to be reliable enough that nutrients do not need to be tracked daily.]
The crew conducted 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-1, FE-2), RED resistive exercise device (CDR, FE-1, FE-2) and VELO bike with bungee cord load trainer (CDR, FE-1). Later, Greg transferred the exercise data file to the MEC laptop for downlink, including the daily wristband HRM (Heart Rate Monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).
At ~10:15am EDT, the crewmembers conducted their regular WPC (Weekly Planning Conference) with the ground, discussing next week's "Look-Ahead Plan" (prepared jointly by MCC-H and TsUP-Moscow timeline planners) via S-band/audio, reviewing the monthly calendar, upcoming activities, and any concerns about future on-orbit events.
The two cosmonauts had their weekly PFCs (Private Family Conferences) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on an SSC laptop), Oleg at ~6:30am, Sergey at ~8:10am.
Working off his suggested "time permitting" task list, Volkov conducted another session for Russia's Environmental Safety Agency (EKON), making observations and taking KPT-3 aerial photography with the NIKON D2X camera of environmental conditions near Tskhinvala and the Baikonur launch site.
Also working from the discretionary task list, Oleg Kononenko conducted another session of the Russian GFI-8 "Uragan" (hurricane) earth-imaging program, using the D2X digital camera with the F800 telephoto lens and the HVR-Z1J SONY video camera. [Uplinked target areas were glaciers on the north slope of the main Caucasus Ridge, the Dombai region, after-effects of border conflict operations in the Caucasus, the Kalmyk steppe, the main stem stream of the Volga river (west-most) from Astrakhan to Caspian Sea, a series of overlapping shots of the Ob and Bia river valleys (Bia river head stream, Teletsk lake, confluence of Katun and Bia rivers form Ob river), general photography of Carpathian region on both sides of track and of the river valleys in Moldova, gulley and ravine topography of Central Russia up to Volga river, steppe on the left shore of Volga river to the south of Saratov including Y. A. Gagarin's landing site in nadir, petroleum deposits along both shores of the Ural river and oil drilling fields, former Soviet Army fire ranges in Germany and coal pits after reclamation, scenic shots of Central America and Caribbean basin for educational purposes, and the Gulf Stream.]

WAICO #1 (Waving and Coiling of Arabidopsis Roots at Different g-levels): A troubleshooting plan has been developed to recover all the BIOLAB functionalities. On 8/4, BIOLAB has been activated from ground for about 5 hours, in order to get telemetry about the Smoke Detector sensor and perform a series of BIT (Built-In Test) sequences. This test was positive and we can confirm the full functionality of the Smoke Detector sensor. Next steps will be resumed in the next coming weeks, starting with the BIOLAB Rotor A bellow test (ground only) and later on the remaining WAICO-#1ECs (Experiment Containers) will be disposed and replaced by 6 Reference ECs on Rotor B. Planning for this last activity is currently TBD.
CEO (Crew Earth Observations): Through 8/4 the ground has received a total of 4,002 frames of CEO images for review and cataloging. Photos this week had camera times corresponding to target list times for the following requests: Western Pamirs (34 frames-hazy, soft), Mount Rainier (single frame-clouds), Coast Mountains (10 frames of target area-mostly cloudy), and Slate Island Impact Crater (single frame-target not acquired). "Preliminary review indicates that we will require additional imagery for all of these targets. We'd like to acknowledge your nice oblique views of Tropical Storm Edouard, acquired in two sessions during the afternoon of 8/4. The storm-precautionary closure of JSC that day and the next precluded any timely processing and release of your images. The hurricane season is still young and you will likely have more chances to photograph these dynamic events. An Increment 17 image acquired on 5/29 will be posted on NASA/GSFC's Earth Observatory website this weekend. The photo is a rare, striking view of the Pyramids of Dashur, Egypt (almost all good photos to date of pyramids are of the ones at Giza). Good illumination and focus accentuate the location and shape of these ancient structures.
CEO photo targets uplinked for today were Kwanza Basin, NW Angola (good pass across the center of this site. Mapping swath of overlapping images at nadir was requested as a basic mapping tool for this rapidly changing area. Visual cues were the linear forested ridges at right-angles to track), East Libya megafans (ancient rivers sourced in the Tibesti Mountains when the climate of the Sahara was wet [> 8000 years ago] have laid down vast spreads of sediment as a series of large fans ["megafans"] hundreds of km long and wide. With more than 150 megafans recently discovered worldwide, the significance of megafans has only recently been understood. A continuous pattern of criss-crossing stream channels, large and small, covers the entire surface of megafans. Looking right beyond the black Namus volcano, Greg's visual cue, for detailed overlapping images of the flat channel-covered plains), Gordion, Turkey archaeological site (a close repeat of a prior pass on 8/7 put this archeological left of track. A mapping swath looking ~45 degrees left should have captured this famous site), Mount Vesuvius, Italy (a close repeat pass puts Vesuvius right of track at the head of the prominent Bay of Naples), Palmyra Atoll, central Pacific (this 6 mile-long atoll is surrounded by a continuous reef which is the scientific feature of interest. Detailed handheld images of coral reefs are being widely used), and Kingman Reef, equatorial pacific Ocean (this 4 mile-long, V-shaped atoll appeared left of track. Handheld imagery is a major component in the effort to map coral reefs worldwide).
CEO photography can be studied at this "Gateway" website:
