2\17 ISS On-Orbit Status 17-02-2003
Part 1 of 2

ISS On-Orbit Status 2/17/03

All ISS systems continue to function nominally, except as noted 
previously or below. Begin of Week 12 for Expedition 6.

CDR Ken Bowersox undertook the scheduled Week 12 water sampling for
in-flight chemistry/microbiology analysis, using the WS&A (water 
sampler & archiver) for collection and the WMK (water microbiology 
kit) for processing within 6 hrs. of the collection. [Samples were 
taken in the Service Module (SM) at the heated-water SRV-K port and at 
the warm-water SVO-ZV outlet. The system was then flushed and the 
chemical analysis performed. After heating SRV-K again, Bowersox then 
took the microbiology sample. Special Flight Surgeon instructions had 
been uplinked to conserve onboard water: Sox was to take the flush 
samples for both the SRV-K Hot and SVO-ZV in his drink bags rather 
than the small waste water bags, after the drink bag was flushed with 
water (the water collected in the drink bags is good for consumption). 
As an alternate to using the drink bags, Sox could also collect the 
flushes into a small waste water bag (from WMK). If the SRV-K hot 
galley port was used within the last hour prior to the sampling 
activity, the flush for this port could be eliminated. After microbial 
water processing was completed, all bags used were to be stowed into 
the WMK.]

FE-1 Nikolai Budarin changed out the Russian SVO-ZV water supply 
system (EDV container, hose and other equipment), then started a 
three-day activity to disinfect and wash the SVO-ZV gear with 
disinfectant solution delivered on Progress-247/10P and water, using a 
hand pump and special receptacles. The disinfection and flushing will 
continue tomorrow and Wednesday.

Bowersox and FE-2/SO Don Pettit took another 30-min. CBT 
(computer-based training with video and audio) refresher course to 
hone their CMO ACLS (crew medical officer/advanced cardiac life 
support) proficiency. [Objectives of today's exercise, which is 
regularly scheduled once a month, were to re-familiarize crewmembers 
with IV (intravenous) fluid infusion, and identification of potential 
causes and complications for treating a tension pneumothorax, using 
the RSP (respiratory support pack).]

Budarin performed the regular inspection/maintenance of the BRPK-2
air/liquid separator in the SM.

Nikolai also completed the daily routine maintenance of the SOSh life
support system, incl. ASU toilet subsystem, as well as the preparation 
of the IMS inventory database for automated file import/export, while 
Sox checked up on Lab payload status (PCG-STES010 temperature).

Pettit took the daily ppCO2 (carbon dioxide partial pressure) readings 
in Lab and SM with the CDMK (CO2 monitoring kit), after breakfast and 
again before dinner.

Bowersox performed the regular monthly maintenance of the CEVIS (cycle
ergometer with vibration isolation), examining the wire rope isolators 
for damage. Later in the day, he also completed the periodic 
inspection of the RED (resistive exercise device), which includes 
checking its bolts for retightening.

All crewmembers worked out on TVIS (treadmill), RED and VELO with load
trainer, completing their daily physical exercise program of 2.5 hrs.

At about 3:20am EST, attitude control of the station was handed over 
to the Russian MCS (motion control system) for conducting a dynamic 
test of an SM ODU manifold-2 yaw thruster (RZ, plane II), which failed 
during the recent Progress 10P docking. For the test, ISS attitude was 
inertial (free drift), then returned to XPOP and handed back to U.S. 
CMG momentum management at 3:48am.

Don Pettit had two hours scheduled for the SIS (Surround Imagery for
Station) procedure, a photographic activity to capture the digital 
still pictures needed to create an advanced 360-degree-view graphics 
of the ISS interior. The illusion of a total surround image is then 
created on the ground by digitally "stitching" the images together 
using QTVR (QuickTime Virtual Reality) software. [The on-board 
photography uses the Kodak DCS 760 (digital camera system) with zoom 
lens between 17 and 35 mm, taking one shot from the center of each 
short module, two shots from the one-third and two-third points in the 
longer modules, and mapping in a circular motion with approximately 
50% overlap between shots. Suggested work-forward sequence was SM, 
DC-1, FGB, Node, JAL, and Lab.]

Budarin sent down another video record from a previous run of the 
Russian "telescience" Plasma Crystal-3 (PK-3) experiment, today from 
1/23/03. For the downlink, the ISS had to be in sight of RGS (Russian 
ground sites).

Also over RGS, at 3:35am, the crew downlinked two PAO TV messages to
MCC-M/TsUP on the occasion of the upcoming (2/22) Russian national 
holiday, "Defenders of the Fatherland Day". One greeting from ISS was 
addressed to the participants of the Russian Armed Forces Day ceremony 
and opening of a Youth Arts Palace in Krasnoznamensk ("Space Heart of 
Russia"), the other to the celebratory gathering at the Kremlin and 
all Russian citizens on 2/22.

Today's targets for the CEO (crew earth observations) program were 
Lake Nasser, Toshka Lakes; Egypt (the crew was asked to continue to 
monitor the vicinity of this large man-made lake in southern Egypt, 
especially looking for changes in the small new lakes to the west of 
the Nile River), Lake Volta in Sun Glint (looking right of track to 
detect details of the shoreline and rivers of this large man-made 
lake), Eastern Mediterranean Smog (although the weather pattern may be 
breaking down by the time of this pass, the view of the Adriatic Sea 
to right of track was too good to pass up. Crew was to look for 
patterns in the smog plumes over this basin in oblique views), and 
Chicago, Illinois (while the Windy City may not have been visible this 
pass, crew was to try looking left of track up the shores of Lake 
Michigan. Of interest is ice in the bays and inlets and views of the 
patterns of lake-effect snows on the western side of lower Michigan).
