All ISS systems continue to function nominally, except those noted previously or below. Underway: Week 5 of Increment 26.
FE-4 Dmitri Kondratyev conducted the regular daily early-morning check of the aerosol filters at the Russian Elektron O2 generator which Maxim Suraev had installed on 10/19/09 in gaps between the BZh Liquid Unit and the oxygen outlet pipe (filter FA-K) plus hydrogen outlet pipe (filter FA-V). [Dima will inspect the filters again before bedtime tonight, currently a daily requirement per plan, with photographs to be taken if the filter packing is discolored.]
Scott undertook his 11th weekly U.S. "Bisphosphonates" biomedical countermeasures experiment, ingesting an Alendronate pill before breakfast. Cady Coleman joined him in this experiment, her 2nd weekly pill ingestion. The required ~10h fast period started last night for both of them. [The Bisphosphonates study should determine whether antiresorptive agents (that help reduce bone loss) in conjunction with the routine in-flight exercise program will protect ISS crewmembers from the regional decreases in bone mineral density documented on previous ISS missions. Two dosing regimens are being tested: (1) an oral dose of 70 mg of Alendronate taken weekly starting 3 weeks prior to flight and then throughout the flight and (2) an intravenous (IV) dose of 4 mg Zoledronic Acid, administered just once approximately 45 days before flight. The rationale for including both Alendronate and Zoledronic Acid is that two dosing options will maximize crew participation, increase the countermeasure options available to flight surgeons, increase scientific opportunities, and minimize the effects of operational and logistical constraints. The primary measurement objective is to obtain preflight and postflight QCT (Quantitative Computed Tomography) scans of the hip. The QCT scans will provide volumetric bone density information of both cortical and trabecular (spongy) bone regions of the hip.]
FE-5 Paolo Nespoli continued his controlled diet for his first (FD15) Pro K session. His diet menu is being recorded on his diet log over the next 3 days. [For Pro K, there will be five in-flight sessions (FD15, FD30, FD60, FD120, FD180) of samplings, to be shared with the NUTRITION w/Repository protocol, each one with five days of diet & urine pH logging and photography on the last day. The crewmember prepares a diet log and then annotates quantities of food packets consumed and supplements taken. Urine collections are spread over 24 hrs; samples go into the MELFI (Minus Eighty Laboratory Freezer for ISS) within 30 min after collection. Blood samples, on the last day, are centrifuged in the RC (Refrigerated Centrifuge) and placed in MELFI at -80 degC. There is an 8-hr fasting requirement prior to the blood draw (i.e., no food or drink, but water ingestion is encouraged). MELFI constraints: Maximum MELFI dewar open time: 60 sec; at least 45 min between MELFI dewar door openings.]
FE-6 Cady Coleman concluded her first (FD15) NUTRITION/Repository/Pro K 24-hr urine collection period, with samples deposited in MELFI. Cady also began her first NUTRITION/Repository/Pro K generic blood collection, with CDR Kelly assisting with the phlebotomy as operator and FE-5 Nespoli taking documentary photography. FE-6 then set up the RC (Refrigerated Centrifuge) for spinning the samples prior to stowing them in the MELFI. [The operational products for blood & urine collections for the HRP (Human Research Program) payloads were revised some time ago, based on crew feedback, new cold stowage hardware, and IPV capabilities. Generic blood & urine procedures have been created to allow an individual crewmember to select their payload complement and see specific requirements populated. Individual crewmembers will select their specific parameter in the procedures to reflect their science complement. Different crewmembers will have different required tubes and hardware configurations, so they must verify their choice selection before continuing with operations to ensure their specific instruction.]
FE-4 Kondratyev configured the hardware for the Russian MBI-21 PNEVMOKARD experiment, then conducted the 1h15m session, his first, which forbids moving or talking during data recording. The experiment is controlled from the RSE-med A31p laptop and uses the TENZOPLUS sphygmomanometer to measure arterial blood pressure. The experiment was then closed out and the test data were downlinked via OCA. [PNEVMOKARD (Pneumocard) attempts to obtain new scientific information to refine the understanding about the mechanisms used by the cardiorespiratory system and the whole body organism to spaceflight conditions. By recording (on PCMCIA cards) the crewmember's electrocardiogram, impedance cardiogram, low-frequency phonocardiogram (seismocardiogram), pneumotachogram (using nose temperature sensors), and finger photoplethismogram, the experiment supports integrated studies of (1) the cardiovascular system and its adaptation mechanisms in various phases of a long-duration mission, (2) the synchronization of heart activity and breathing factors, as well as the cardiorespiratory system control processes based on the variability rate of physiological parameters, and (3) the interconnection between the cardiorespiratory system during a long-duration mission and the tolerance of orthostatic & physical activities at the beginning of readaptation for predicting possible reactions of the crewmembers organism during the their return to ground.]
FE-1 Kaleri terminated the overnight (10-hr) charging of the Kelvin-Video battery for the Russian KPT-12 payload with its BAR science instruments suite, and then he conducted a one-hour test run with the BAR equipment to check out the performance of the remote IR (Infrared) Kelvin-Video thermometer. [Objective of the Russian KPT-12/BAR science payload is to measure environmental parameters (temperature, humidity, air flow rate) and module shell surface temperatures behind SM (Service Module) panels and other areas susceptible to possible micro-destruction (corrosion), before and after insolation (day vs. night). Besides KPT-2 Piren-B, the payload uses a remote infrared thermometer (Kelvin-Video), a thermohygrometer (Iva-6A), a heat-loss thermoanemometer/thermometer (TTM-2) and an ultrasound analyzer (AU) to determine environmental data in specific locations and at specific times. Activities include documentary photography with the NIKON D2X camera and flash.]
