Crew rest day.

Station sleep cycle is now back to the regular 1:00am - 4:30pm EST.

For FE-2 Dan Tani, it was Day 1 of the two-day activities of the HRF CCISS (Human Research Facility/Cardiovascular & Cerebrovascular Control on Return from ISS) experiment. CDR Peggy Whitson assisted with electrode placement and documentary photography. (CCISS studies the effects of long-duration spaceflight on crewmembers' heart functions & blood pressure (="cardiovascular") and on the blood vessels that supply the brain (="cerebrovascular"). Learning more about the changes in cardiovascular & cerebrovascular systems in zero-G could lead to specific countermeasures that might better protect future space travelers. Today's activities focus on hardware set-ups including the Holter harness for heart rate monitoring (with PCMCIA card), the CBPD (Continuous Blood Pressure Device) cuffs, and two Actiwatches (not the same as for SLEEP). For the Baro study of CCIS, using finger cuffs, heart rate and blood pressure were recorded for resting and timed breathing for 5 min. Between today and tomorrow, there is also a 24-hr passive data collection period. Exercise, caffeine or food are not allowed prior to the Baro study.)

Peggy Whitson worked on updating and deploying new SODF (Station Operation Data File) Warning Books. (The new books are valid for post-P6 activation. They are deployed in the Lab, Service Module (SM), and FGB.)

FE-1 Yuri Malenchenko performed the regular daily maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including routine ASU toilet facilities replacings.

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 (CDR), TVIS treadmill (FE-1, FE-2), RED resistive exercise device (CDR, FE-2), and VELO bike with bungee cord load trainer (FE-1).

Yuri then transferred the crew's exercise data file to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

At ~7:35am EST, the FE-1 downlinked two PAO TV messages of greetings via S-band to TsUP/Moscow: (1) to Yaroslavl Region Militia Officers on the Day of Militia ("...Yaroslavl Militia honorably and courageously protects law and order at the birthplace of Valentina Vladimirovna Tereshkova, Hero of the Soviet Union and first woman cosmonaut...") ; (2) the other to TsUP Director Vladimir Ivanovich Lobachev who will have his 70 th birthday on 11/8 ("...for almost a quarter of a century, you've been at the helm of the Mission Control Center. We know that you started your professional career working under the direct supervision of Sergei Pavlovich Korolev... Vladimir Ivanovich, we would like to express our deep gratitude to you for your truly fatherly care for us space workers. Once again, happy birthday to you!")

Later, at ~8:40am, FE-2 Dan Tani held a crew conference via Ku- & S-band with the next FE-2, Garrett Reisman, who will be his successor after arriving on STS-123 in February next year. (Performed every other week, these 30-min. crew conferences are being included in the current station crew's schedule to pass on the lessons learned to the upcoming Expedition Crew. The purpose is to begin the handover process prior to the arrival on orbit through Videocons and Data Exchanges between the current crew and the upcoming crew. These tagups should start toward the end of the 1 st month on orbit.)

EWIS Update: After FE-2 Tani yesterday reconnected EWIS (External Wireless Instrumentation System) 1553 cabling in the Lab, EWIS has been successfully activated. (The structural dynamics measuring system is monitoring in "trigger" mode dynamics of the P4, P5 and S4 truss segments. Data of the activation are currently being reviewed by engineers.)

STS-120 Landing Preview: For tomorrow's planned touchdown of STS-120/Discovery, KSC has two opportunities: i.e., from Orbits 238 & 239. Weather at KSC is forecast GO.

First opportunity (Orbit 238): Deorbit Burn (TIG) - 12:00pm EST

Landing --- 1:02pm;

Second opportunity (Orbit 239): Deorbit Burn (TIG) - 1:34pm

Landing - 2:36pm

No CEO (Crew Earth Observations) target uplinked for today.
