NASA Space Station On-Orbit Status 17 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.
Station reboost occurred at 9:12am EST as scheduled, producing a delta-V of 1.6 m/s, against an expected value of 2.6 m/s. Resulting altitude increase was 2.9 km instead of 4.4 km expected. MCC-Moscow (TsUP) is investigating the underburn of the Progress thrusters. [Attitude control was transferred from the U.S. (USOS) to the Russian segment (RS) at ~6:45am, followed by TsUP-commanded maneuvering to LVLH (local vertical/local horizontal) reboost attitude at 6:53am. Station attitude control returned to USOS at ~10:00am, to remain in LVLH TEA (torque equilibrium attitude) until about mid-December.]

Previous Reports ISS On-orbit Status [HQ] |
FE Salizhan Sharipov spent most of his working hours in the Docking Compartment (DC1) to conduct a thorough functionality checkout of Russian Orlan-M spacesuit #27 and its power, telemetry, communications, BSS cooling interface unit and other environment control & life support (ECLS) subsystems in its backpack. More EVA suit work is scheduled tomorrow when Salizhan will deinstall recyclable components like the Beta-8 ECG (electrocardiogram) equipment from Orlan #12 prior to the latter’s disposal in Progress 15. [For the Orlan checkout, the US/Russian C&T/audio and STTS/video systems were reconfigured for covering the EVA work from the DC1 and later reset to nominal config. Later in the day, Sharipov also recharged the batteries of the DVCAM (DSR PD-1O) video camera used for the activity.]
CDR/SO Leroy Chiao set up another activity run of the SNFM (Serial Network Flow Monitor) application. [First, activation of EXPRESS Rack 5 (ER5) was ground commanded, followed by power up of its laptop (ELC-5) by Chiao to support subsequent network flow monitoring/capturing downlinked LAN-2 traffic with ELC-5, then of LAN-2 ops using the ELC of ER4. Once initiated, downlink traffic (of directory file lists for each ER active on this increment) via SNFM was under ground control and did not require crew support.]
Both crewmembers completed the standard emergency medical operations CHeCS OBT (Crew Health Care Systems/on-board training) drill, a 30-min. exercise to refresh Crew Medical Officer (CMO) acuity in applying (advanced cardiological life support (ACLS) in an emergency. [Today’s computer-based proficiency drill focused on re-familiarization with the Respiratory Support Pack (RSP) under various alternate applications, Defibrillator, and Crew Medical Restraint System (CMRS).]
Leroy Chiao conducted Inventory Management System (IMS)-supported cleanup activities in the Lab/Node “rack corridor”.
Later, the CDR filled out his regular weekly FFQ (food frequency questionnaire), his fourth, which keeps a log of his nutritional intake over time on special MEC (medical equipment computer) software. Work continues on the ground to put together the food allocations for launch on Progress 16P. [The FFQ provides for recording consumed amounts during the past week of such food items as beverages, cereals, grains, eggs, breads, snacks, sweets, fruit, beans, soup, vegetables, dairy, fish, meat, chicken, sauces & spreads, and vitamins.]
Salizhan completed the daily standard maintenance/inspection of the SM’s environment control & life support systems (SOZh) and prepared the regular IMS “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, and VELO cycle with bungee cord load trainer. Afterwards, Chiao downloaded TVIS and RED exercise data files to the MEC.
Sharipov worked on his BIO-5 Rasteniya-2 (“Plants-2”) zero-G growth experiment, today collecting the plants grown in the Lada-5 “greenhouse” and stowing the bagged samples for later return to Earth.
After manual full and zero calibrations of the U.S. MCA (major constituents analyzer) yesterday and Monday, the MCA is indicating invalid partial pressure readings. Troubleshooting is underway. [With the exception of ppN2 (nitrogen), all partial pressure values have jumped up after the calibration and are not supported by CSA-CP (compound specific analyzer-combustion products) and other sources. In spite of its inaccuracies, the MCA is left up and running for now so that fault and trend data can be dumped from its computer to help in diagnosing the problem.]

ISS Location NOW |
Update on PL-2 MDM: MCC-Houston and POIC (Payload Operations & Integration Center/Huntsville) are working on a recovery plan for the failed #2 payload computer.
Update on SIGI GPS2 failure: Failure investigation of the newly upgraded SIGI-2 (space integrated GPS/inertial navigation system #2) continues. Based on results of an antenna/electronics test, GPS antenna assembly #2 has been determined to be failed at this time. Next step is to load test data to SIGI2 only, in order to exonerate the antenna problem as a possible cause of the SIGI-2 firmware issue. [While state vector solutions from SIGI-2 are good, as indicated by comparison with SIGI-1 and Russian data, specialists are continuing today to assess the attitude output performance and to verify the full set of memory parameters against the ground configuration in the test facility. Early this morning, ISS has transitioned to LVLH TEA attitude after the reboost maneuver; the new attitude now provides a different environment in which to characterize the R2 firmware performance. Meanwhile, both SIGI-1 and Russian attitude sources remain available.]
Today’s CEO photo target, limited in the current XPOP attitude by flight rule constraints on the use of the science window, which is available for only ~1/4 of each orbit when not facing forward (in ram), were Smog, North China Plain (Dynamic event. Looking for a visibility boundary between smoggy air nearer track [Shanghai region] and clearer air off track further north over Beijing), and Dust, smoke, India (Dynamic event. A polluted air mass, generated in the Ganges plain against the Himalaya range, is flowing E, then S, out into the Bay of Bengal. It then circulates back into southern India. It should be possible to document this large circulation from the streamlines in the air mass: looking mainly left towards India. Images to the right may show up the margin between the polluted and clear air over the dark sea surface).
