ISS On-Orbit Status 12 Feb 2003
All ISS systems continue to function nominally, except as noted previously
or below. Day 81 in space for Expedition 6.
After wake-up (1:00am EST) and before breakfast, FE-1 Nikolai Budarin
concluded his current MBI-8 "Profilaktika" (countermeasures)
fitness session, today conducting the blood test part, measuring lactate
and creatine kinase levels with the AccuSport equipment, and the physical
exercise on the TVIS treadmill. [The TVIS test is identical to the MO-3
test performed on the treadmill in idling mode with free choice of speeds
within a certain specified range. In addition to the nominal test procedure,
it calls for the use of the TEEM-100M gas analyzer during the test, the
blood measurements, and subjective evaluation of physical exertion levels
during the test. Gas analyzer and ECG (electrocardiograph) data were
transferred to Laptop 3 and prepared for later downlink via Regul-Packet
comm.]
Later, Budarin conducted a checkout of the Russian GAMMA-1M blood pressure
(AD) monitor, by testing the AD cuff, with its cuff hose and cable, on
a simulated arm (a rounded container).
CDR Ken Bowersox and Budarin continued unloading and transferring Progress
10P cargo, with IMS record-keeping.
FE-2/SO Don Pettit set up the acoustic dosimeters for static noise measurements.
Using the MEC (medical equipment computer) with special "EARQ" software,
all crewmembers later recorded audiograms measured by their individual
portable dosimeters for several hours.
Nikolai Budarin completed removal and replacement of two components
of the SM BITS2-12 on-board measurement telemetry system, viz., an old
memory unit (ZU1-A) and the BP11-A on-board transmitter. During the R&R,
a number of Russian subsystems were temporarily disabled, such as the
SKV-1 air conditioner, Vozdukh control algorithm, BMP micropurifier,
Elektron, and the BITS itself. [The ZU memory device, one of four, uses
200m of magnetic tape to store and reproduce data. The BP11-A transmitter,
one of four, is used to transmit telemetry data from the SM to the ground.]
Budarin also checked the gas analyzer in the SM, to verify its readings,
then tagging up with ground specialists via S-band.
Later, Nikolai, working at the SM Central Post, continued and completed
the battery cycling of the three new laptops delivered by Progress 10P.
Bowersox performed troubleshooting on EXPRESS Rack 2 (ER2). [He focused
on two main approaches: (1) re-cabling the ER2 laptop back to nominal
Ethernet configuration with a clean rebooted RIC (rack interface controller),
then trying to re-establish Ethernet Comm. If successful, the ground
was to continue with the loading of the laptop with the new software.
(2) If not successful, ground was to continue with the second troubleshooting
activity, which uses the ER3 laptop and Ethernet cable on ER2.]
Bowersox and Pettit conducted a refresh review of the DOUG (dynamic
operational ubiquitous graphics) software with new files for tomorrow’s
SSRMS/Robotics operations. [DOUG is a sophisticated software program
that provides a graphic birdseye-view graphical image of the SSRMS (space
station remote manipulator system), showing its real-time location and
configuration on a PC during its operation.]
In the morning and evening, Don Pettit again sampled ppCO2 (carbon dioxide
partial pressure) levels in the SM and Lab with the CDMK (CO2 monitoring
kit).
Budarin downlinked video recorded previously of the Russian Plasma Crystal-3
(PK-3) payload. He also completed his routine 24-hr. checkup and watering
of the Russian BIO-5 Rasteniya-2/Lada-2 ("Plants-2") plant
growth experiment.
Ken Bowersox completed the daily routine maintenance of the SOSh life
support system in the SM (incl. ASU toilet system) as well as the daily
IMS (inventory management system) delta file preparation for automated
export to MCC-M/TsUP. Sox also performed the daily Lab payload status
checkup of the autonomous PCG-STES010 payload.
The planned R&R of the LAB1P5 RPCM (remote power controller module),
which controls the VTR1 video recorder, has been deferred. [When trying
to perform a preemptive refresh of the RPCM, the ground received an unexpected
health flag. While it is believed that the event is fully understood,
engineers want to assess it completely before proceeding.]
The crew was congratulated on their outstanding interactive TV downlink
for PAO yesterday. Today, at 10:30am, they shared in a second and equally
successful TV interview with a number of media clients, viz., CNN, ABC
World News Tonight, CBS Early Show, and NBC Nightly News. All exchanges
went exceedingly well. [As yesterday, the crew found confident words
in responding to media questions on the topics of the tragic loss of
Columbia, the resumption of Shuttle flights and the potential difficulties
associated with reducing ISS crew size to two.]
ECLSS (environment control and life support systems) engineers on the
ground are continuing troubleshooting (t/s) of the degraded IMV (intermodular
ventilation). [The t/s performed by the crew last week was sufficient
enough to focus on an examination of the flow straightener that is integrated
on the Node IMV fan package. The straightener is of a honeycomb structure
and approximately 4-millimeter diameter. For the next t/s, the crew will
remove the flexible air duct below the IMV fan and examine the flow straighteners
with a mirror to check for blockage. Depending on the results, the crew
may have to scavenge a corresponding Lab IMV fan for use in the Node
location.]
Onboard water supply: There is currently a total of 986.3 L water onboard,
which will provide approximately 164 days, assuming condensate recovery
and processing in the Russian SRV-K system as well as use of potable
water for technical purposes.
R&R of SM battery #7 is scheduled for tomorrow.
Today’s targets for the CEO (crew earth observations program) were Industrialized
Southeastern Africa (a stagnant area of high pressure is located over
southern Africa allowing for atmospheric aerosol accumulation over the
region. The ISS pass was NW of most of the area of interest, and the
crew was to try for oblique or limb views to the right of track to detect
the depth and extent of the smog pall), Lower Amazon River Basin (with
ISS tracking over the northwestern portion this target, crew was to look
right of track for views of the southeastern estuaries of the Rios Para
and Tocantins. Some sun glint enhancement was possible this pass), Eastern
Mediterranean Dust (satellite imagery continues to show dust streaming
northeastward off the Libyan-Egyptian coast. Looking obliquely right
of track to document this phenomenon), Western Mediterranean Smog (winds
and weather favor smog formation in central Med between the big islands
of Sardinia and Corsica and the Italian mainland. Looking left of track
for oblique views), and Eastern Mediterranean Smog (crew was asked to
continue to look left of track for smog formations, especially over the
Po River valley and the northern Adriatic Sea).
