All ISS systems continue to function nominally, except as noted previously or below.

CDR/SO Michael Foale set up the video hardware for recording imagery of his subsequent general MedOps PFE (periodic fitness evaluation), which checks up on blood pressure and electrocardiogram during programmed exercise on the CEVIS in the Lab.  Readings were taken with the BP/ECG (blood pressure/electrocardiograph), with FE Alexander Kaleri assisting his crewmate as CMO (crew medical officer).  The video equipment was then stowed again. [BP/ECG provides automated noninvasive systolic and diastolic blood pressure measurements while also monitoring and displaying accurate heart rates on a continual basis at rest and during exercise.  The video is required for biomechanical evaluation of the subject and his equipment setup during data collection.]

Kaleri replaced the BKO multifiltration unit of the SRVK-2M condensate water processor, which has reached its service life limit.  The BKO was replaced with a new unit and stowed for deorbiting in Progress 12P.  [The BKO, which contains five purification columns to rid the condensate of dissolved mineral and organic impurities, has a service lifetime of at least 450 liters throughput.]

At the Russian SVO-ZV water supply system, Sasha Kaleri changed out the EDV container, hose and other equipment, then started a three-day activity to disinfect and wash the SVO-ZV gear with disinfectant solution, delivered on Progress-248/12P, and water, using a hand pump and special receptacles.  The disinfection and flushing will continue tomorrow and Wednesday.

Mike Foale checked out the MedOps cardiac defibrillator, a periodic routine task that is scheduled as soon as possible from Expedition start and every 60 days thereafter.  [For the checkout, the defib is connected to the 120V outlet, equipped with its battery, today #1007, and then allowed to charge, for about five seconds, to a preset energy level (e.g., 100 joules).  After the button-triggered discharge, a console indicator signals success or failure of the test.  The pacing signal was to be downlinked via S-band for 1.5 min.]

Kaleri began another round of monthly preventive maintenance of the Russian segment (RS) ventilation system, starting out with cleaning the Group A fans and grilles in the SM, then replacing the four SM dust collector filters (PF1-4) with new cartridges (last time done: 9/22).

CDR Foale printed out new uplinked procedure pages (Loss of CMG Attitude Control) and incorporated them in the onboard caution table library.

Mike also changed out the battery of the back-up CSA-CP (compound specific analyzer-combustion products), which provides the daily measurements of air constituent partial pressures (pp).

Later, Mike called down the “ad hoc” ppO2 of the cabin air. [O2 data for trending analyses by the ground are collected daily by the crew with the CSA-CP.]

At 9:10am EST, Foale set up the PAO video equipment.  At 9:30am, he and Sasha Kaleri downlinked several greeting messages in support of upcoming PAO events, viz., for (1) an All Hands meeting of the ISS Program Office at JSC tomorrow (11/6); (2) a tour of KSC by a NATO Parliamentary Assembly group on 11/10 (on Excursion Day from their 49th
Annual Session in Orlando, FL, 11/7-11); and (3) the fifth Anniversary of the launch of FGB “Zarya”, the first ISS element launch, on 11/20/1998.

Both PCUs (plasma contactor units) have been activated and are currently in Discharge mode, at the request of the Plasma Hazard Evaluation Process (PHEP) Team to collect additional data to continue establishing a relationship between the charging hazard, ambient ionospheric conditions, and the flight configuration/attitude.  [The station’s two PCUs, attached to the Z1 truss (deployed on Mission 3A), emit a stream of charged xenon atoms (ions) and electrons into space.  The plasma acts as a “ground” to the environment, which prevents large charges from building up on the station, thus controlling the voltage between the ambient plasma and the ISS structure.  Today’s PCU activation was not done to mitigate a perceived risk, but to gain data on PCU performance for this flight attitude/configuration and the current ambient ionospheric conditions.]

First instructions for troubleshooting the failed Russian cycle ergometer (VB-3) were uplinked for the crew.  Sasha was to open the control module panel cover and inspect the panel mount for possible defects.  Results are to be reported to TsUP for IBMP.

The crewmembers again had a “free” hour each for station familiarization and acclimatization, as is standard daily rule for the first two weeks after starting station residency.

At 6:31pm EST today, Moscow is scheduled to reboot/reintegrate the three lanes of the SM’s Terminal Computer (TVM) that is currently running on only one lane.  There will be no crew involvement.  [The TVM restart will be done with “context data”, where the USOS (U.S. segment) remains in control throughout the restart after appropriate reconfiguration (to inhibit actions involving the TVM, such as desaturation requests, automatic attitude control handover to the RS, etc.).  Prior to the restart, prestored commands (cyclograms), uplinked ahead of time by TsUP, will shut down the Elektron oxygen generator, the SKV air conditioner and the BMP micropurification system in the RS, returning it to service afterwards.]

Today’s CEO (crew earth observation) targets, taking into account the current LVLH attitude, and including the targets of the Lewis & Clark 200-year memorial locations, wereAthens, Greece (looking a touch left),Nile River delta, Egypt(land use patterns in the intensively farmed delta are changing, due to increasing population pressure, urbanization and particularly due to salt poisoning of fields from modern irrigation practices [every acre newly colonized from the desert along the fringes of the delta is lost within the delta from salt]),Cairo, Egypt(looking a touch right.  The city now straddles the entire width of the delta [near its base] having developed in the last two decades in the direction of the pyramids on the west side),Lancaster, PA (LEWIS & CLARK SITE:  Looking a touch right of track. Lewis spent three weeks here with Andrew Ellicott, mathematician and astronomer, who instructed him in the technique of determining latitude and longitude and advised him on the purchase of navigational instruments),Philadelphia, Pennsylvania(LEWIS & CLARK SITE: After being commissioned by President Jefferson, Lewis moved to Philadelphia in early 1803. He took crash courses in medicine, botany, zoology, and celestial observation. He studied maps and journals of traders and trappers who had already reached as far up the Missouri River as the Mandan villages in North Dakota.  By the time he set out he knew as much about the West as any man in America.  Looking at nadir for a pass over the city center), Rio de Janeiro, Brazil(looking at nadir on the major bay on the coast.  The city airport lies on an island in this large, well-protected bay), Las Vegas, Nevada(nadir pass),Phoenix, AZ(nadir pass.  Two 180-mm-lens images should be sufficient to capture the whole urban area),Tucson, Arizona(nadir pass),Mexico City, Mexico(looking a touch left for this vast city of about 25 million people),Puebla, Mexico(looking a touch right for this city that lies on the opposite side of the volcanic chain from Mexico City.  As these two cities grow towards one another, they constitute one of the largest urbanized regions in the world), and Lake Poopo(handheld imagery has shown that water levels in this lake on the high desert of the central Andes fluctuates not seasonally but according to the longer El Nino cycles.  The antiphase relationship means that the lake should be filling in the present inter-ENSO phase).
