NASA Space Station On-Orbit Status 14 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. Sunday — off-duty day for Sergei Krikalev & John Phillips, except for some housekeeping and voluntary tasks. Ahead: Week 17 for Increment 11.
The crew’s sleep cycle remains shifted two hours to the right, with wakeup this morning at 4:00am EDT. Sleep period begins at 7:30pm tonight. The crew will remain on this schedule until Tuesday, August 16.
As part of today’s morning inspection after wake-up, CDR Krikalev did the periodic checkup behind panel 139 in the Service Module (SM) on a fluid connector of the urine collection system, checking for potential moisture.
Sergei also performed the daily routine maintenance of the SM’s SOZh environment control & life support system, which today included the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP/Moscow.

FE/SO Phillips worked on the preparation of his Kodak DCS 760 digital still camera for the spacewalk on Thursday (8/18), assembling batteries, three lenses with caps (25mm, 35mm, 50mm) and a special 1-gigabyte EVA flash card for image storage.
Working off his Russian “time available” task list, Sergei performed the long-term recurring task of imaging the externally mounted PKZ-1V Kromka 1-3 contamination experiment tablet. [The Kromka tablet, deployed on handrail 2614 of the DC-1 “Pirs” docking compartment, collects thruster plume effluents. The pictures are taken with the Kodak 760 DSC from the EVA hatch 1 (VP1) “illyuminator” (window) in the DC-1.]
As in the last few days, TsUP/Moscow continued primary testing of the ASN-M satellite navigation system in the SM for the European ATV (Automated Transfer Vehicle), without crew participation.
Tomorrow morning, in an effort to increase orbital drag of the station to meet Soyuz 11 rendezvous requirements, the P6 PV (photovoltaics) solar array wings 2B and 4B will be set to 120 deg sweep (dual angle mode) without the usual drag reduction during eclipse (Earth’s shadow portion), until autotrack is required for EVA-14. [For the XPOP (x-axis perpendicular to orbit plane) period directly after EVA-14 until 18P undock, the P6 PV arrays will be operated in autotrack with specific angular bias settings. The drag increase can be tracked in the regular ISS Orbit table, below.]
As usual, the US segment MCA (Major Constituent Analyzer) was set to rapid sampling mode about 30 min before the periodic repress of the cabin atmosphere with gaseous O2 from Progress 18 and later returned to nominal auto sampling sequence (4x Lab, 4x Node, 4x Airlock).
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).]
