NASA Space Station On-Orbit Status 10 June 2003

All ISS systems continue to function nominally, except as noted previously or below.

In preparation for Progress 11P docking tomorrow morning, CDR Yuri Malenchenko supported MCC-Moscow/TsUP in a test of the Soyuz Klest-103Ts video camera, activating it and using the VKU2 TV display screen to monitor its operation over a 3-hr. period.  [At about 8:00am EDT, test images of the ISS interior were downlinked to TsUP, with the transmitter activated/deactivated by the SPP automated daily timeline system.]

Science Officer Ed Lu powered up the MSG (Microgravity Science Glovebox), then supervised another experiment session with the InSPACE (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment.  Afterwards, the MSG was powered down again.  [Today’s test was the first for coil assembly #6 (CA006).  Three remaining test runs are planned with CA006, which contains the largest particles (0.66 microns).  These tests will be used to complete the planned matrix and may also be used to check for recurrence of an observed phenomenon of particle/wall interaction.  Today’s test (#23) had current amplitude (1.048 amps) and frequency (10 Hz) remaining constant throughout its duration.]

Malenchenko completed a 80-min job of periodic maintenance of the station’s ASU toilet system, changing out two T-hoses and two sensors, viz., the urine line sensor (VD-U) and the flush water sensor (VD-SV).  The old hoses and sensors were discarded.

Ed Lu opened the MCA (major constituents analyzer) valve in the Lab, in support of a full calibration run commanded by the ground.  Afterwards, the valve was closed again

The CDR terminated the 24-hr. regeneration cycle for adsorbent bed #2 of the BMP harmful impurities filtration unit.  Both filter channels are now back in Purify mode.

Malenchenko continued the current maintenance cycle on the RS (Russian segment) ventilation system, today changing out the four dust collector filters (PF1-4) in the Service Module (SM).  Last time done: 5/15. 

In the FGB/Zarya module, Yuri then cleaned ventilation fan grilles behind interior panels.  Last time done: 5/8.

In preparation for the video taping of the Progress docking, Ed Lu had time reserved for cleaning VTR (video tape recorder) heads.

The Science Officer completed the daily routine maintenance of the SM’s SOZh environment control & life support system as well as the daily preparation of the IMS inventory “delta” file.

Both crewmembers conducted their regular daily physical exercise program of 2.5 hrs.
As part of his physical exercise time, Ed Lu completed another 1.5-hr. session of the periodic general MedOps PFE (periodic fitness evaluation), which checks up on blood pressure and electrocardiogram during programmed exercise on the CEVIS in the Lab.  Readings were taken with the BP/ECG (blood pressure/electrocardiograph).  Yuri Malenchenko assisted his crewmate as CMO (crew medical officer).  [BP/ECG provides automated noninvasive systolic and diastolic blood pressure measurements while also monitoring and displaying accurate heart rates on a continual basis at rest and during exercise.]

Progress 11P continues its flight, slowly catching up with the ISS for tomorrow morning’s docking at 7:17am EDT.  Major activities for today, third flight day, were tests of onboard systems and functions.  As Progress is approaching the station, trajectory measurements and systems monitoring are continuing.  [Test procedures involved the Klest-M TV camera system, starting at 5:19am EDT on Daily Orbit 1 (DO1) over Russian ground sites (RGS), with activation of the camera, its transmitter, wide-angle and narrow-angle lenses, alphanumerical display and the spotlight.  Maneuver data for the third correction burn (DV3) were uplinked in two parts on DO1 and DO2, and the maneuver was performed at 7:45am.  Also tested was the MCS (motion control system), which maneuvered from solar-oriented attitude (ISK) to inertial attitude (OSK) and back.  During DO3 (orbit 34), at 8:24am, the TORU backup docking system was checked out, including its VHF primary transceiver.]

During the docking process, MCC-H plans a data take with the IWIS (internal wireless instrumentation system).  At the same time, the IWIS run is also intended to determine battery performance, as they are allowed to be depleted during the run.  Before the next data take, for the 10P/Progress undocking, the batteries will be changed for all IWIS units.  [IWIS uses radio-linked accelerometers (RSUs, remote sensor units) in SM, Lab and Node to take structural dynamics (vibratory) measurements.]

Today’s CEO (crew earth observation) targets, no longer limited in the current LVLH attitude and including the targets of the Lewis & Clark 200-year memorial locations, were Johannesburg, South Africa (the South African capital lied to the right of track), Karachi, Pakistan (this Pakistani port city lied to the right of track.  Looking for dusty conditions as well), Tigris-Euphrates, Turkey (CEO is monitoring lakes levels in this rugged area where numerous dams are being constructed), Tunis, Tunisia (the Tunisian capital is located on the north coast, just left of track), Lima, Peru (the crew had a near-nadir pass over the Peruvian capital on the coast as they approached from the SW), Delhi, India (CITY AT NIGHT: The air may have been be dusty, but this mega city was just to the right of track), Council Bluff, IA (LEWIS & CLARK SITE: This Iowan city lies just across the Missouri River from Omaha, Nebraska), and Omaha, NE (LEWIS & CLARK SITE: Nebraska’s largest city is located on the west side of the Missouri River).
