NASA Space Station On-Orbit Status 30 October 2004
SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by SpaceRef.com (copyright © 2004) to enhance access to related status reports and NASA activities.
All ISS systems continue to function nominally, except those noted previously or below. Saturday — first weekend rest day for the crew.
After breakfast, CDR/SO Chiao and FE Sharipov performed the regular weekly three-hour station cleaning. [“Uborka”, done every Saturday, includes removal of food waste products, cleaning of compartments with vacuum cleaner, wet cleaning of the Service Module (SM) dining table and other surfaces with “Fungistat” disinfectant and cleaning fan screens to avoid temperature rises.]
Afterwards, Chiao shut down the EarthKAM (Earth Knowledge Acquired by Middle School Students) system in the Lab on Day 5 of its operation and stowed the equipment. EarthKAM will be back the first week of February. [By last night, 367 images had been captured with the 50mm lens and over 400 images with the 180mm lens.]
Leroy worked on the IBM 760XD SSC (station support computer) client laptops in the SM (SSC1 & SSC2), loading them with the new vers. 23 software brought up on Progress 15P. [Due to the timing of load releases and Expedition crew assignment changes, the current software (vers. 21.01) does not have the login IDs for either Chiao or Sharipov. Vers. 23 has Leroy’s profile, and Salizhan can access his email on the SSCs in the SM with a temporary new login. Three new ThinkPad A31p laptops for use in the Russian segment (RS) are planned for launch on 16P, along with a new software load.]

Previous Reports ISS On-orbit Status [HQ] |
At 8:20am EDT, Sharipov and Chiao had their first weekly planning conference (WPC) with the ground to discuss the “Look-Ahead Plan” for next week (regularly prepared jointly by MCC-H and TsUP planners), via S-band/audio.
Afterwards, at 9:50am, after their lunch break, the crew also held the once-every-two-weeks teleconference with ISS Program Management in Houston via S-band/audio.
The FE performed the daily routine maintenance of the SM’s SOZh life support system, including ASU toilet facilities.
Both crewmembers completed their daily 2.5-hr. physical exercise program on TVIS treadmill, CEVIS bike ergometer, RED exerciser and VELO cycle with NS-1 with bungee cord load trainer.
Leroy downloaded TVIS exercise data files to the MEC (medical equipment computer) as is standard procedure when several sessions have been performed on the treadmill since last download.
Yesterday’s CEVIS/TVIS inspection showed that the CEVIS aft overhead isolator exhibits wear on three or four of the 12 wire ropes that make up the isolator. The TVIS inspection was nominal. [For the CEVIS, this level of fraying is considered nominal wear, but a more detailed evaluation is underway by ground specialists. At this time, the crew is still “Go” to exercise on the bike, since a total of eight wire ropes must show excessive fraying before the isolator is considered failed.]
Elektron Status: The Elektron is operating nominally, and ppO2 levels continue to recover. The crew noted bubbles in one of the EDV water containers used to supply condensate water for the O2-producing electrolysis process. Since the Elektron’s Liquid Unit does not tolerate excessive air bubbles in the water feed, this EDV, which has not yet been connected to the Elektron, was to be subjected to an air/water separation procedure tonight to remove the excess air.
P6 Battery Reconditioning Status: The P6 4B solar arrays battery #2 (4B2) reconditioning operations, begun on 10/25, have proceeded nominally so far. The second battery discharging should be finished in the next 24 hours. Batteries will then be charged, after which there will be one more discharge/charge cycle to test the capacity of the reconditioned battery set. That last cycle is expected to start sometime early next week. After the capacity test, BCDU (battery charge/discharge unit) 4B2 will be brought back on-line. [Initial results indicate that the reconditioning process has increased the capacity of the 4B2 battery, but ground specialists must still complete their evaluation before a quantitative assessment is available.]

Crew Earth Observations (CEO): CEO investigators have received and reviewed a total of 186 of CEO images taken by the new crew to date. They are very impressed with “your long session of imagery acquired on 10/25, the day before we began submitting CEO target lists. The 93 photos were taken with the 800mm lens demonstrated rapidly improving techniques and skills with this challenging camera configuration. We look forward to applying this talent to some of our science targets in the near future”.
Today’s CEO photo targets, in the current LVLH attitude not limited by flight rule constraints on the use of the Lab nadir/science window, were Sobat fans, SE Sudan (this overpass provided an opportunity for high-resolution photography of this mega fan complex. The fans originate from the Ethiopian highlands to the east. They can be recognized by large areas of highly complex drainage patterns and the presence of swampland. Mapping swaths of the drainage patterns are particularly useful for delineating the margins and general form of the fans), Lower Amazon River Basin, S. America (ISS passed over the apex point of the Amazon River delta. This provided an opportunity for high-resolution mapping of this important hydrologic interface for detection of morphological changes), and Beni River dynamics, Bolivia (this flyover presented an opportunity for high-resolution mapping of current and prior river channels. These data are used to track small-scale changes in river morphology and fluvial processes).
