NASA Space Station On-Orbit Status 22 August 2005
SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by SpaceRef.com (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. Another post-EVA crew rest day. Underway: Week 18 for Increment 11.
The crew started their workday by debriefing with ground specialists on last Thursday s successful EVA-14.

Sergei Krikalev initiated the regeneration cycle on absorbent bed #1 of the Russian harmful impurities removal system (BMP). Later tonight, the bake-out to space will be terminated and the vent valve closed. [Regeneration of each of the two cartridges takes about 12 hours; it is not being conducted during crew sleep. The BMP is currently still using the same vacuum vent valve for regeneration as the Elektron (the latter for venting hydrogen), which is still inactive.]
John Phillips performed maintenance work on two EMU (extravehicular mobility unit) batteries with BC3 (battery charger 3). [One battery, #2050, flown up in the LF-1 MPLM (multipurpose logistics module), needs an automated maintenance cycle consisting of a full charge, followed by a discharge, for a total duration of the cycle of about 40 hours. The other, #2062, used for the first and third EVA from STS-114/LF-1, only needs to be discharged, which takes about 16 hours.]
With the Matryoshka payload on the outside of the Service Module (SM) dismantled and retrieved during EVA-14, the CDR today disconnected its SUBA (onboard equipment control system) cable from the Russian payload server (BSPN). The task was supported by ground specialist tagup via S-band. [Matryoshka used a spherical body-simulating Matryoshka-R phantom and a human torso model outside on the SM hull to automatically gather on-orbit radiation and long-term dose accumulation data which were regularly downlinked from the BSPN.]
Working from his discretionary time available task list, Krikalev also replaced two 3COM network jumper cables in the SM, one for the SSC1 (Station Support Computer 1) laptop at the Central Post and the other at the SSC2 laptop in the sleep station, plus their network cards.
FE Phillips used an MPEV (manual pressure equalization valve) internal sampling adapter, VAJ (vacuum access jumper) and scopemeter to conduct a pressure check on the PMA-3 (Pressurized Mating Adapter 3) which the crew used for storage and repressed/depressed in June this year (after which they discovered a very small air leak). When last checked on 6/23, pressure was 21.7 Torr (mmHg). Today s reading was 29 Torr, indicating an acceptable leak rate.
Sergei performed the daily routine maintenance of the SM’s SOZh environment control & life support system, including the ASU toilet system and the weekly inspection of the BRPK air/liquid condensate separator apparatus. He also was asked to adjust a sensor on Channel 2 of the IK0501 gas analyzer (GA) of the SOGS pressure control & atmospheric monitoring system, tagging up with ground specialists.
At ~10:25am EDT, John set up the Sputnik-SM Kenwood D700 amateur radio station in the SM and at 10:30am conducted a ham radio session with high school students in Sapporo, Japan, organized in the Sapporo Junior Amateur Radio Club to foster their interest in electronics. [Questions to the crew were uplinked beforehand. Can you see the lights of Sapporo now? ; What is your fun on the ISS? ]
Both crewmembers conducted their regular 2.5-hr. physical exercise program on the TVIS treadmill, RED resistive machine and VELO bike with bungee cord load trainer. [Sergei s daily protocol prescribes a strict four-day microcycle exercise with 1.5 hr on the treadmill and one hour on VELO plus load trainer (today: Day 3 of a new set).]
Station attitude continues in XPOP (x-axis perpendicular to orbit plane), until 9/2, and the P6 solar array wings are set to dual-angle autotrack, with BGA (Beta gimbal assembly) 2B at -36 deg, 4B at +36 deg angle.
