NASA Space Station On-Orbit Status 31 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. Sunday, with the crew off duty for the day. Ahead: Week 2 of Increment 10.
Salizhan Sharipov completed the regular daily maintenance/inspection of the Service Module (SM)’s environment control & life support systems (SOZh), including routine toilet system (ASU) replacements. Part of the FE’s SOZh job today was the weekly inspection of the BRPK air/liquid condensate separator apparatus and data collection of the SM’s toilet flush counter readings, with inspection of the urine collection (SP) & pretreat assembly and water supply status (SVO) counter readings, both for calldown to TsUP/Moscow.

Previous Reports ISS On-orbit Status [HQ] |
Leroy Chiao had a second session 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. [The crew personalized Salizhan’s own SSC email folders using file material uplinked overnight, to correct the lack of his profile in the new vers. 23 software for the SSC laptops.]
Both crewmembers completed their daily 2.5-hr. physical exercise program on TVIS treadmill, RED exerciser and VELO cycle with NS-1 with bungee cord load trainer.
Working off the crew-discretionary Russian task list, FE Sharipov completed the periodic 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.
As a second activity from the Russian “job jar” list, Salizhan conducted his first session with the biomedical MBI-9 “Pulse” experiment, preceded by setting up the equipment. [Execution of the medical cardiological assessment is controlled from the Russian payload laptop, using a set respiration rate (without forced or deep breaths) and synchronizing respiration with computer-commanded “inhale” commands. First, arterial blood pressure is measured with the “Tensoplus” sphygmomanometer, followed by the “Pulse” test to record the ECG (electrocardiogram) and a report to TsUP in the next comm pass.]
At ~8:05am EST, ISS attitude control was handed over to the Russian SUD motion control system (MCS), followed by a thruster-effected maneuver to the test attitude required for conducting today’s SM and FGB solar array efficiency testing. The test itself took ~6.5 hrs, and ISS maneuvered to XPOP TEA (x-axis perpendicular to orbit plane/torque equilibrium attitude) at 2:50pm, followed by control handover to the U.S. CMGs (control moment gyroscopes) at ~3:05pm. Part of the time the Elektron was deactivated to reduce RS power loads. [The periodic Russian efficiency testing keeps track of the energy-output performance of the photovoltaics over time under the degrading effects of the space environment (mostly from ultraviolet radiation and atomic oxygen). Since the test requires the full power output of the solar arrays and the FGB itself does not have sufficient loads for drawing it, the U.S. side, on request, increased U.S. loads via RACU 6 (Russian-to-American Converter Unit #6) up to 1238 W today, increasing and decreasing in steps of ~200 W each two minutes. The procedure has been used four times before (4/3/03, 11/11/03, 3/5/04 & 6/16/04.)]
