ISS On-Orbit Status 11 Jul 2003

Part 1 of 3

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

CDR Yuri Malenchenko performed maintenance on the common power
switching unit (BSK) of the Russian segment's (RS) onboard equipment
control system (SUBA), replacing five fuses in a circuit breaker plug
with new fuse links, then storing the old fuses as spares.  The
activity was supported by tag-up with MCC-M.  [The SUBA controls,
monitors, and diagnoses Service Module (SM) systems status.  It
operates using sensor output signals and command radio link SM
functional outputs, onboard computer system (BVS) units, SM control
panels, and system relay outputs.  Its software resides in the SM
central computer (TsVM) and terminal computer (TVM).  The BSKs are
used to switch electrical power and protect electrical circuits with
fuses against overloads.]

Later, Malenchenko reconfigured electronic cables in the SM to
connect the Regul-OS antenna feeder unit (AFU) to the antenna feed in
a new arrangement. This task was deferred from 6/24.

FE/SO Ed Lu performed another ppCO2 (carbon dioxide partial pressure)
data take from the new CSA-CP (compound specific analyzer-combustion
products) brought up on 11P.  (Last time done: 7/3).   [CSA-CP is a
toxicology monitoring device for early CO detection/warning and
post-fire decontamination.  It also checks for hydrogen chloride
(HCl) and other combustion products and contaminants.  Data takes are
regularly collected for downlink.]

Malenchenko performed the periodic air sampling in the station, first
using the standard Russian AK-1M sampler device in the SM and FGB.
Later, testing for CO (carbon monoxide) levels, he collected SM air
samples with the IPD Draeger tubes sampler.

Ed Lu conducted an inventory and inspection of fire ports in the
Node, to verify emergency clearance constraints.  [Primary purpose
was to video record the fire ports (panel access openings) for ground
evaluation of potential blocking in an emergency.  Rearrangement of
easily movable items could be done at the discretion of the crew,.]

The Science Officer also took documentary photography for POC
(Payload Operations Center) of the MSG (microgravity science
glovebox) umbilical connections, for the historical record.  [FOV
(field-of-view) data and downlink info was uplinked overnight.]

The CDR concluded the current run of the Molniya-SM/LSO experiment
and uninstalled its hardware from SM window #3 for stowage.  [This
latest session was started on 7/7.]

After the aborted installation of the electrical heater of the
catalyst cartridge (PKF-T) in the SM's micropurification filtration
system (BMP) on 7/2, which apparently did not fit in place,
Malenchenko today was scheduled to check the dimensions of the heater
unit and tag up with ground specialists via S-band.

Later, Yuri continued the latest maintenance cycle on the RS
ventilation system, today removing and replacing the two PS1/PS2 dust
collector filters in the FGB air ventilation system, disposing of the
old filters (last time done: 6/6).

After a very successful week's run, the current EarthKAM (Earth
Knowledge Acquired by Middle school students) operations came to an
end today.  Ed Lu deactivated the system, dismantled the equipment at
the Lab nadir window and stowed its components.  [This was the first
ever "Summer" mission for EK and the results have reportedly been
"terrific".  In addition to the normal student use, many teachers
received hands-on training so they can bring EK into their
classrooms.] 

Ed supported the ongoing NGL (Next Generation Laptop) testing, which
today called for the third data collection and log file take.  [Ed's
periodic support consists of copying  the accumulated files of the
automated test program from the new laptop's microdrive over to the
SSC (station  support computer) laptop for data collection and
subsequent downlink.  The microdrive is then returned to the NGL and
the DOS-based test program restarted.]

Ed Lu completed his ninth weekly filling-out of the FFQ (food
frequency questionnaire), which keeps a log of his nutritional intake
over time on special medical equipment computer (MEC) software.

Yuri Malenchenko attended to his regular daily inspection of the
BIO-5 Rasteniya-2 ("Plants-2") experiment which studies growth and
development of plants (peas) under spaceflight conditions in the
Lada-2 greenhouse.

The CDR also completed the regular periodic (weekly) inspection of
the active BRPK-1 air/liquid condensate separator in the SM.

The SO performed the periodic transfer of physical exercise data
files of the TVIS treadmill, RED resistive exerciser and CEVIS cycle
ergometer to the MEC (medical equipment computer), for subsequent
downlink to the ground (last time done: 7/3).  [The file transfers
involve PCMCIA (portable computer memory card international adapter)
cards from TVIS and CEVIS, plus the entries from the RED exercise log
book, individually for each crewmember.]

Later,  Ed Lu also copied the accumulated data files from the
receiving stations of the wrist-worn HRM (heart rate monitor) to the
MEC for downlink, then deleted them on the HRM (last time done: 7/3).

On the operational PCS (portable computer system) laptops in the ISS,
Ed performed the regular once-a-week maintenance reboot.

Yuri prepared the daily inventory management system (IMS) "delta"
file for updating the database and conducted the weekly IMS tagup
with the ground via S-band, in response to a number of uplinked
questions on stowage locations. 

Ed Lu took care of the daily status checkup of autonomous Lab
payloads (SAMS, MAMS, PCG-STES010).

Also on Ed's schedule was the third session for his recording of
video scenes of a two-day onboard tour for the "Live on ISS" PAO TV
program, started on Thursday.  Today, he edited the recordings, which
will be downlinked on 7/17 (Thursday next week).  The downlink, with
live crew narration, will be aired on NASA TV.

At 10:50am EDT, Yuri Malenchenko participated in a teleconference
with school children at TsUP/Moscow in a PAO TV downlink initiated by
the RS automated daily time sequencer (SPP).  [The live-TV exchange
featured student winners of a Space Science Projects competition from
different towns of Russia, assembled at TsUP for the ISS event.]

Later in the day (3:55pm EDT), Ed Lu is scheduled to tag up with
science students at Los Alamos University, NM, via S-band/audio.

The crew will also have their weekly teleconference with the ISS
Flight Director at MCC-H.

At 2:41pm EDT, the station will maneuver to LVLH +YVV/"barbecue"
attitude (vertical y-axis in velocity vector, i.e., facing "top"
forward) for six orbits, to allow gathering temperature and power
data for the scheduled mid-Beta angle range analysis test.
Afterwards, at 1:36am tomorrow morning, flight attitude will return
to XPOP.  [Projected power availability in YVV (autotrack): 24.1 kW
from 2B & 4B combined.  XPOP (autotrack w/bias): 22.4 kW from both.]
