2\06 ISS On-Orbit Status 06-02-2003
Part 1 of 2

ISS On-Orbit Status 2/6/03

All ISS systems continue to function nominally, except as noted 
previously or below. Day 75 in space for the Expedition 6 crew.

Kudos went up to the crew for their great work yesterday in tracking 
down all consumables on board. This gives MCC-H and MCC-M a head start 
on developing plans for the remainder of this increment and continued 
manned station occupancy.

CDR Ken Bowersox yesterday also took an inventory audit of CWCs 
(contingency water containers). With water being the limiting 
consumable in the current Shuttle stand-down situation, onboard water 
storage and getting the Russian SRV-K H2O processing system to work 
for U.S. condensate are of prime importance.

Bowersox and FE-1 Nikolai Budarin continued unloading Progress 
10P/M-47, accompanied by careful bookkeeping for the IMS (inventory 
management system) database, using an uplinked extensive cargo list 
for 10P with assigned ISS stowage locations. Unpacking a Progress, 
with its often surprising "care packages", is always a thrill for a 
station crew.

FE-2/SO Don Pettit worked on the MSG (microgravity science glovebox), 
which tripped a circuit breaker upon activation yesterday, very 
similar to what was seen before the MSG failure on 11/20/02. As MSG 
specialists from ESA and NASA are developing a troubleshooting plan, 
Pettit's activities today focused on salient data gathering, following 
specific instructions uplinked last night in an EFN (electronic flight 
note).

Nikolai Budarin performed preventive maintenance on the FGB 
ventilation system, replacing its two dust filters (PS-1 and 2).

Budarin also conducted his regular daily checkup and watering, as 
required, of the BIO-5 Rasteniya-2/Lada-2 ("Plants-2") plant growth 
experiment. Later, he copied its accumulated photo/data files to a 
floppy disk for transfer to the Russian laptop 3 and subsequent 
downlink via Regul-Packet.

Bowersox took the two daily carbon dioxide (CO2) readings in the 
Service Module (SM) and Lab with the CDMK (CO2 monitoring kit), in 
support of the currently ongoing investigation of the discrepancy 
between the CO2 readings of the MCA (major constituents analyzer) in 
the U.S. segment and the CO2 measurement in the Russian segment with 
the SM gas analyzer (GA). [At issue are not only the suspect data of 
the GA, but also the lack of proper IMV (intermodular ventilation) 
between the segments.]

Sox also set up for tomorrow's scheduled Foot (foot/ground reaction 
forces during space flight) experiment run, preparing the equipment 
for EMG (electromyography) calibration with video recording, and for 
the actual data take in the specially equipped outfit.

Budarin transferred newly arrived Russian med/tech Bradoz A3 hardware 
from the Progress and deployed it in the SM, after taking pictures of 
the hardware for the record and saving them from the Nikon 
CompactFlash card to a laptop HDD (hard-disk drive). [Bradoz (RBO-2) 
is a bio-radiation dosimetry experiment that uses kits deployed in 
specific SM locations with minimum, maximum or average levels of 
radiation protection within two days after delivery. After the 
completion of the experiment, the samples must be isolated from 
exposure to electromagnetic radiation as much as possible.]

Bowersox and Pettit conducted another session for the 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).  Each of the two in turn 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.]

Nikolai performed the daily routine maintenance of the SOSh life 
support system as well as the preparation of the IMS "delta" file for 
downlink.

MCC-M/TsUP performed a smoke detector test in the DC-1 docking 
compartment via S-band, then deactivated the "cycle" mode of FGB 
battery #5 and activated it for battery #6. SM battery #6 was also set 
to cycling mode. [In cycle mode (RTs), the battery is twice discharged 
down to 24 volts, then recharged to 32.5V at least once every two 
weeks. Each battery requires about 18 hours for the process. Cycle 
mode is performed to rid the battery of its "memory" and restore the 
electrical characteristics of the storage unit. It also resets 
accumulated errors in the battery's charge/discharge current 
integrator (MIRT).]

The Cupola RWS PCS (robotic workstation/portable computer system) 
suffered a hard failure over last weekend. PCS spares are on board but 
are not usable until after the pending 12A software transition.

The Russian LiOH (lithium hydroxide) canister test performed over the
weekend, lasting more than 38 hrs, was deemed successful by MCC-M. The 
test was in support of re-certification of the LiOH canisters' 
lifetime.

Next ISS reboost, by Progress 10P, is scheduled for 2/11 (Tuesday), at
6:49am EST. The burn will last 21 min 48 sec and provide a delta-V of 
6 m/sec, increasing station altitude by 10.4 km.

Today's targets for the CEO (crew earth observations program) were Red
Basin, China (Dynamic event. The break in cloudy weather continues 
with high pressure promoting continued smog buildup: these conditions 
allow comparative views of this site from two days ago. The circular 
Red Basin [oblique left of track] has 100 million people and major 
cities. Suggested were obliques and short lenses [or series of tighter 
views] to capture the full span of the basin and the smog event. Any 
flow lines in the smog indicating a sense of the transport direction 
would be interesting to document), Three Gorges Dam, Yangtze R. (nadir 
pass. Mapping swath requested (i.e., overlapping views). The dam wall 
lies in a dark and deep canyon and can be difficult to discern, but 
the vast construction sites on both banks should stand out), Kinshasa, 
Congo (this capital city lies a touch right on the south bank of the 
Congo River [where the river widens at "Stanley Pool"]), Baghdad, Iraq 
(nadir pass; ESC [electronic still camera]. Also, this was an 
opportunity to shoot sun glint views of the complex river pattern in 
Mesopotamia, and the new dusting of snow on the Zagros Mts and other 
ranges in Iran [for about 1.5 mins after Baghdad]), Eastern 
Mediterranean Dust (gusty winds were kicking up dust off the coast of 
Egypt.  [Then there was an opportunity to shoot Crete in sun 
glint--right of track]), Algiers, Algeria (nadir pass for this coastal 
city; ESC), Bogotá, Colombia (nadir pass; ESC. The city appears as an 
elongated gray mass in the valley [valley reported cloud free compared 
with mountain ranges to east and west cloudy]), St. Louis, Missouri (a 
touch left of nadir; ESC), and Detroit, Michigan (nadir pass; ESC).
