NASA Space Station ISS On-Orbit Status 18 November 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.
FE Sharipov continued his current work on EVA systems in the Docking Compartment (DC1), today stripping still-useful components off the to-be-discarded #12 Orlan-M suit, in particular the electronic processor box (BPU) of the “Beta-08” ECG (electrocardiogram) equipment,for return to the ground. [Other removed nondisposable items include the BK-3 backup oxygen tank, the KVO liquid cooling garment, the ShL headset and the emblem patches on the Orlan’s sleeves. Before disassembling a pressure sensor (2DS-450) from the BK-3M tank, Salizhan released the tank’s residual O2 (~180 at) into the cabin atmosphere.]
CDR/SO Chiao completed the IMS (Inventory Management System)-supported rack “corridor” consolidation & cleanup, which he started yesterday. The last portion of today’s task was a teleconference with specialists at MCC-H to discuss Leroy’s disposition tables line item by line item.

Afterwards, Chiao printed out latest procedures for Node, Lab and Airlock fire source locations for bringing the two EMER-2 warning & emergency operations books up to date, including a new location for the backup CSA-CP (compound specific analyzer-combustion products) and pump. Along with the EMER-2 updates, Leroy later also installed temporary ID labels at the various fireports (=panel openings for fire extinguisher nozzle insertion).
Sharipov set up the equipment for a video downlink, subsequently activated/deactivated by the Russian SPP automated daily timeline sequencer, of a 10-min clip of the spectrometric recordings of the reentry of 8S/Soyuz TMA-4 with the geophysical GFI-1 Relaksatsiya (“relaxation”) experiment’s ultraviolet (UV) camera on 10/24.
At ~7:10am EST, Leroy and the ADUM (Advanced Diagnostic Ultrasound in Micro-G) ground team held their post-session analysis to discuss the successful ultrasound scans performed on Salizhan earlier this week.
In the DC1, Salizhan was to install labels (if missing) on two air duct covers, one between the BVN1 screen and DC1 airduct in the Soyuz Habitation Module (BO), the other in FGB stowage for the BVN2 screen.
The FE also performed the periodic replenishing of the Elektron’s condensate water supply for electrolysis, his fourth, filling the KOV thermal loops EDV container with purified (deionized) water from the BKO multifiltration/purification column unit.
After reviewing an uplinked procedure and setting up the video camcorder, the crew spent ~20 min on an EPO (Educational Payload Operation) demo of Living Onboard the Station, in which they took the viewer on a tour of the space station’s habitation areas. The scenes were downlinked via S- & Ku-band and recorded on the ground for NASA educational use.
The FE completed the regular daily maintenance/inspection of the Service Module (SM)’s environment control & life support systems (SOZh), today including the weekly inspection of the BRPK air/liquid condensate separator apparatus. He also prepared the regular IMS “Delta” file for export/import to the IMS databases.
At ~6:45am, Salizhan also tagged up with IMS specialists on the ground to conduct his weekly review of open issues concerning identification of equipment and storage locations for IMS updating. [Today’s main topic dealt with the current location of the laser retroreflectors (LSV) and their covers and other database entries.]
An additional task for Sharipov, on the Russian discretionary task list, was the removal of the Nikon D-1 ESC (electronic still camera)’s digital memory card and its replacement with a newer LEXAR 512MB card.
The crew performed their daily 2.5-hr. physical exercise program on TVIS treadmill, RED exerciser, and VELO cycle with bungee cord load trainer. Afterwards, Chiao attended to the daily transfer of TVIS and RED exercise data files to the MEC (medical equipment computer).
A “marathon” activity of Leroy Chiao for the next five days will be to perform the periodic maintenance on EVA batteries, which regularly are taken through charge-discharge cycles for reconditioning. In preparation for the activity, the CDR was to secure a hardcopy of the procedures since the responsible SSC (station support computer) laptop will be occupied with battery discharge commanding.
Last night, about one hour prior to crew sleep, the CHeCS (Crew Health Care Systems) rack smoke detector annunciated a fire alarm, which careful investigation determined to be false, probably triggered by a transient piece of debris. [The ground performed the False Fire Alarm Recovery procedure, reactivating step-by-step the equipment that was shut down by the software response to the fire alarm. The CHeCS rack was not powered up again until this morning so the crew could get to sleep on time.]
Yesterday’s functional checkout on Orlan suit #27, which had been delivered on 15P, by Sharipov went generally well, except for problems with suit communication on Russian VHF-1 radio. The Orlan-M was stowed, and Moscow is investigating whether the comm problem was ISS- or ground-based.
Ground-commanded operation of the SNFM (Serial Network Flow Monitor) application continued, today including configuration of the PEHB (Payload Ethernet Hub/Bridge) and enabling/disabling the ARIS POP (Active Rack Isolation System/Payload On-orbit Processor) power by the Payload Rack Officer (PRO).
Update on 15P reboost: A special troubleshooting team convened by Moscow/RSC-Energia continues to investigate yesterday’s Progress-350 thruster underburn, which yielded a delta-V of only 1.63 m/s as opposed to the expected 2.6 m/s. Resulting altitude increase was 2.4 km instead of 4.4 km. Preliminary reports are that both Progress hardware and software performed nominally. One of the aspects under investigation is available propellant supply. Also under study is the issue how soon to conduct a second reboost (which Progress-350 apparently would not be able to perform for lack of prop).
Update on SIGI GPS2 failure: Failure investigation of the newly upgraded SIGI-2 (space integrated GPS/inertial navigation system #2) continues. Separate from the firmware issue, it appears that GPS antenna assembly #2 is failed, even before the software loading. The SIGI-2 antenna system is nonredundant, i.e., if the antenna itself is found to be failed, only SIGI-1 would be left for attitude determinations (state vector updates remain unaffected), in addition to Russian attitude sources. Antenna-2 is EVA-replaceable, and a spare is available, but on the ground.
Today’s CEO photo targets, no longer limited in the current LVLH attitude, were Typhoon Muifa, W. Pacific Ocean (Dynamic Event. This Category 2 storm is predicted to move westwards towards Manila. The best cloud banding features should have been on the eastern edge of the storm system), Salamat Basin fans, Chad (this overpass provided an opportunity for oblique photography of these megafans. Looking for wetlands and contorted drainage patterns that delineate fan boundaries. Oblique images of the fans provide useful context for mapping), and Internal waves, E & W Florida coasts (weather was predicted to be clear over the western Florida coast for internal wave photography. Looking to the left of track close to the coastline for the sunglint point).
