NASA Space Station On-Orbit Status 14 March 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.   Underway: Week 21 of Increment 10.

Main crew activity today dealt with the removal & replacement (R&R) of the corroded heat exchanger (HX) of the EVA Service & Performance Checkout Unit (SPCU) in the Joint Airlock (A/L) with a new unit delivered on Progress 17.  So far, things have been going well and close to schedule.  [The HX R&R, spread over several days, began last Thursday with setup of video equipment to monitor A/L activities, procedures printout, training preps, familiarization with the newly delivered equipment, tagging up with ground specialists, and setup of the FSS (Fluid Servicer System) in the A/L for the TCS work.  Scheduled for today were the removal of the old HX and the installation of the new one in its place, followed by leak checks with special hardware.  The activities are closely monitored by the ground via the A/L video camcorder.  Next steps after the leak checks will be final ops and rack re-rotation.  If everything continues to go well, on 3/16 we should see final cleanup, re-stowage, and dismantling of the FSS.]

FE Sharipov performed the first part of his third round of the Russian preventive health maintenance fitness test series MBI-8 “Profilaktika”, starting with the VELO stationary bike ergometer.   [There will be two more tests, one with the NS-1 Load Trainer tomorrow, the other with the TVIS treadmill on 3/16.  Test procedure is identical to the Russian MO-5 assessment, but in addition to the nominal procedure, it calls for the use of the TEEM-100M gas analyzer, measurement of the lactate level in the subject s blood with the AccuSport device, and subjective evaluation of physical exertion levels during the test.  Results are entered on a log sheet.  TEEM and ECG (electrocardiograph) data are transferred to Laptop 3, also on a tape cassette (Cardiocassette-2000), and prepared for later downlink via OCA or Regul-Packet comm.  The lactate levels were called down to specialists standing by at TsUP.]

Sharipov also conducted the periodic (annual) visual inspection of the Service Module (SM) pressure hull in the Working Compartment (RO) behind panels 130, 134, 135, 138 and in the pit underneath the TVIS treadmill, looking for any moisture, deposits, mold, corrosion and pitting.   [Salizhan inspected the hull surface, which is coated with a primer and dark-green enamel, using cleaning napkins to wipe the area in question if required, taking digital photos before and after the wiping, and reporting results to the ground.]

The FE completed the periodic maintenance chore of changing out components of the SM toilet system (ASU), then checked out the ASU.   [Replaced with new units were the U-receptacle (MP) and filter insert (F-V).  The old items were logged in the IMS (Inventory Management System) database and stowed for disposal.]

Afterwards, Salizhan performed the daily routine inspection of the SOZh life support system in the SM and completed the periodic calibration check of the IK0501 gas analyzer (GA) via its IG-3 oxygen (O2) sensor unit, supported by tagup with ground specialists.   [IK0501 is an automated system for measuring CO2, O2, and H2O in the air, as well as the flow rate of the gas being analyzed.]

FE Sharipov also prepared the regular IMS (inventory management system) delta file for export/import to the IMS databases.

The crew performed their daily 2.5-hr. physical exercise program on TVIS treadmill, RED exerciser, CEVIS cycle and VELO cycle with bungee cord load trainer.  Salizhan’s VELO exercise today was accounted for by his MBI-8 Profilaktika session (see above).

Afterwards, Leroy transferred the daily 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, followed by their erasure on the HRM storage medium.

Working off the voluntary Russian task list, Salizhan performed the regular daily inspection of the BIO-5 Rasteniya-2 (“Plants-2”) experiment, which researches growth and development of plants under spaceflight conditions in the Lada-5 greenhouse.

Also added to the Russian task list was a brief inventory/audit of onboard equipment for recording ASN-M (satellite navigation system) data to Laptop 3 in an important experiment to be conducted by ESA cosmonaut Roberto Vittori during his upcoming VC8 visit.

As a third task list item, Salizhan is to perform an audit of available wipes intended exclusively for cleaning rubber seals on module hatches.

Troubleshooting by TsUP/Moscow is currently underway on the Elektron O2 generator that failed to run properly after the crew s electrolyte/bubble separation activity last Saturday (3/12).  The shutdown was caused by excessive line pressure, indicative of a possible obstruction in either the H2 or O2 vent lines.   [Backup O2 is available from Progress 17 storage and SFOG candles.  By next Wednesday, TsUP will decide whether to go proceed with plans for EVA-13 on 3/28, which would postpone further Elektron troubleshooting until after the EVA, or to delay the EVA until the Elektron is fixed.]
