NASA Space Station On-Orbit Status 3 December 2005

 SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by (copyright © 2005) to enhance access to related status reports and NASA activities.

All ISS systems continue to function nominally, except those noted previously or below. Saturday — off-duty day for Bill McArthur & Valery Tokarev, except for housekeeping and voluntary work…and undoubtedly for some concerns by the CDR about the Army-Navy Game (rooting for the former).

The crew performed the regular weekly three-hour task of thorough station cleaning, wearing protective garment.   [“Uborka”, normally done every Saturday, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the Service Module (SM) dining table, other surfaces and the FE’s sleep station with “Fungistat” disinfectant and cleaning fan screens to avoid temperature rises.]

FE Tokarev also performed the daily routine maintenance of the SM’s environment control & life support system (SOZh), including its toilet system (ASU).

Both crewmembers completed their regular 2.5-hr. physical exercise program on the TVIS treadmill, RED resistive exerciser and VELO bike with bungee cord load trainer.   [Valery’s daily protocol prescribes a strict four-day microcycle exercise with 1.5 hr on the treadmill in unmotorized mode and one hour on VELO plus load trainer (today: Day 2 of the first set).]

Afterwards McArthur transferred the TVIS and RED exercise data files to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM (Heart Rate Monitor) data from the workouts, followed by their erasure on the HRM storage medium (done six times a week)

After successfully completing the first part (of three) of the VOA (Volatile Organics Analyzer) repair yesterday, today the CDR performed the second portion, i.e., getting on with replacing the thermal fuses of both traps and IMS (Ion Mobility Spectrometer) cells as well as components such as the nitrogen dryer, oxygen scrubber, sieve packs, pumps, fans, and filters.

After McArthur’s cleaning of the CHeCS rack’s AAA (Avionics Air Assembly) fan and plenum orifices on 12/1 did not result in increased air flow from the AAA (to support VOA activation), specialists are developing a plan of action, viz., to let the CDR finish the VOA IFM (in-flight maintenance), and then replace the AAA next week.  Last night, McArthur also offered to do further troubleshooting on the CHeCS (Crew Health Care Systems) rack and provided several suggestions, which are under consideration.

At ~8:35am, the crew held their regular weekly planning conference (WPC) with the ground, discussing this week’s “Look-Ahead Plan” (prepared jointly by MCC-H and TsUP/Moscow timeliners), via S-band/audio, reviewing upcoming activities and any concerns about future on-orbit events.

Valery Tokarev worked approximately five hours yesterday transferring cargo from Progress 19 and stowing the items in ISS, with commensurate updates of the IMS (Inventory Management System) database.  Last night, the FE indicated he would need approximately three more hours to complete 19P unloading of 19P.

Measurements indicate a slightly higher ppCO2 (carbon dioxide partial pressure) level in the US segment (USOS) than in the Russian segment (RS).  The ventilation ducts in the FGB are in nominal configuration and the instruments in the RS (SM GA/Service Module Gas Analyzer) and USOS (Lab MCA/Major Constituents Analyzer) are tracking nominally together.  Ground specialists continue to evaluate this condition, but no CDRA (Carbon Dioxide Removal Assembly) operations are necessary at this time.
