NASA Space Station On-Orbit Status 22 October 2007

All ISS systems continue to function nominally, except those noted previously or below. Day 137 for Anderson. Underway: Week 1 of Increment 16. Crew rest day.

Crew wake/sleep cycle has “normalized”, Today’s wakeup – 1:00am, sleeptime – 4:30pm EDT.

By her voluntary choice, CDR Whitson conducted her first work with the CFE (Capillary Flow Experiment) payload, completing the detailed mapping of the CFE VG-1 Vane Gap 1) vessel. After a successful session, Peggy disassembled the equipment and stowed it. [CFE consisted of three experiments – CFE-CL (Contact Line), CFE-ICF (Interior Corner Flow), and CFE VG, for the study of different aspects of capillary flow of fluids in containers with complex geometries. Except for today’s run on the model of fuel tanks with locating vanes (to determine the maximum allowable vane gap and sensitivity to asymmetry), the CFE experiments have been concluded.]

In further preparation for the upcoming STS-120/10A docked period, the crew performed a 90-min. review of the 10A timeline, followed by a timeline teleconference with ground specialists via audio/S-band.

Peggy Whitson disconnected the UOP DCP (Utility Outlet Panel/Display & Control Panel) bypass power cable from the Lab RWS (Robotics Work Station).

The crewmembers worked out according to their regular daily 2.5-hr physical exercise 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 exerciser (CDR, FE-2), and VELO cycle with bungee cord load trainer (FE-1).

Afterwards, Clay Anderson transferred the crewmembers’ exercise data file to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM (Heart Rate Monitor) data, followed by their erasure on the HRM storage medium (done six times a week).

At ~7:45am EDT, the crew downlinked a PAO TV message of greetings for an upcoming Science Festival at Rice University, to be held on Saturday, 10/27, sponsored by Sally Ride, with Eileen Collins as keynote speaker. Special emphasis of the event will be on female students at Rice and the importance of their pursuing a future in science and math.

At ~12:10pm, FE-2 Clay Anderson supported a “Crew Choice” linkup with Grade K students, college students and faculty at Hastings College, Nebraska (Clayton’s school). Questions for the FE-2 were uplinked beforehand. [“Did you know you wanted to be an astronaut when you were in 6th grade?”; “I’ve heard reports that astronaut food is “gross”. Any truth to this?”; “What are the possible risks for not following the work-out routine?”; “While a student at Hastings College, did you ever think that one day you would be an astronaut for NASA and is that what you were striving for while working toward your undergraduate/graduate degrees?”]

Later today, Whitson and Anderson will have their weekly PFCs via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on the SSC-9 laptop), Peggy at ~1:25pm, Clay at ~5:05pm.

SARJ Anomaly: At ~10:36am, Flight Controllers in Houston started a 3-hr. test on the starboard Solar Array Rotary Joint (STBD SARJ) in order to troubleshoot the cause of some vibration observed on the STBD side of the station’s truss structure when the SARJ on that side rotates, combined with some off-nominal readings on some STBD SARJ parameters. After the test, the STBD SARJ remains “parked” at 240 deg angle until the wing feathering prior to 10A docking. [Purpose of the TAS (Torque-As-Stepper) test, which torqued the array through 360 deg with small angular steps, was to help in characterization of the SARJ’s friction. Both BGAs (Beta Gimbal Assemblies) and TRRJ (Thermal Radiator Rotary Joint) remained in Autotrack mode. The regular BGA Bias setting (for drag reduction) was zero to maximize power generation during the test.]

EWIS Update: Most cables for EWIS (External Wireless Instrumentation System) were successfully installed by the crew last Saturday (10/20). Last step was not completed, but it is on the “job jar” task list to be finished when the crew has time.

Conjunction: A possible ISS conjunction with space debris on 10/24 (Wednesday) at 8:59pm EDT is currently being assessed by station and Shuttle teams. Early prediction of miss distance: 25 km.

KOB-2 Heating Loop Pump Failure: The Russian TCS (Thermal Control System) in the Service Module (SM) experienced an off-nominal automatic switch from KOB-2 (heating loop 2) to KOB-1. Checkouts determined that one of two pumps on the 4SPN2 pump panel is not working. The KOB-1 loop is running nominally with two pumps functioning on its pump panel and nominal software algorithms. Specialists are considering installing two new pumps (delivered on 15S) for restoring both panels with two pumps functioning on each.

SRVK-2 Failure: Also in the SM, channel 2 of the SRVK-2 water processing/supply system failed during the last four days. SRVK-1 is operating normally. Assessment by RSC-Energia specialists is underway.

Correction: Re yesterday’s item on the offnominal ballistic re-entry of Yurchikhin, Kotov & Shukor in Soyuz TMA-10: Bowersox, Budarin & Pettit, who re-entered ballistically on 5/3/03 in TMA-1, were ISS Expedition 6, not Expedition 3. (See pictures from Kustanai yesterday, below)

No CEO (Crew Earth Observation) photo targets uplinked for today.

CEO photography can be viewed and studied at the websites: (about 700,000 NASA digital photographs of Earth are downloaded by the public each month from this “Gateway” site);

STS-120/Discovery Launch Update: The launch window opens tomorrow, 10/23, at 11:33am EDT and closes 10 min later, at 11:43pm. Optimal launch time is 11:38am.
