NASA Space Station On-Orbit Status 21 August 2005

SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by (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 18 for Increment 11. 

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.

Krikalev finished EVA-14 closeout ops by discharging the second Orlan backpack battery (825-M3) during the day, then stowing it with the ZU-S charge/discharge unit in the DC1 docking compartment.

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.

At ~8:00am EDT, the crew held their weekly 20-min. teleconference with ISS Program Management at JSC/Houston via S-band/audio. 

Later, at ~10:00am, Sergei had his weekly PFC (private family conference) via S-band/audio and Ku-band/NetMeeting video (which employs a USB camera at the SSC laptop).   [Controllers had to overcome some temporary audio relay problems between Goddard and Sergei’s party at TsUP/Moscow, later also a 5-min. loss of video before the link was re-established satisfactorily.]

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 2 of a new set).]

The crew reported another LHA (Lamp Housing Assembly) failure in the Lab (pos. LABOS5).  John Phillips replaced it with an LHA scavenged from the Raffaello MPLM (Multipurpose Logistics Module) during LF-1.

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.
