ISS On-Orbit Status 26 Jun 2003

Part 2 of 3

The crew also received kudos for the successful completion of the RED
(resistive exercise device) Flexpack replacement in canisters #1009
and 1010.  [Both replaced Flexpack units, to be installed in
canisters 1001 and 1003 in a separate IFM, are still judged quite
useable as spares.] 

Moscow reported a problem with RS laptop #1.  [After its failure
during the recent Progress-259/11P docking, it could not be restarted
yet since this requires a boot diskette is needed which the crew as
to date been unable to locate.  For the time being, payload control
laptop #3 has been reconfigured as backup machine to laptop #2 which
has primary station control.] 

SM storage battery #4 continues to be off-line and is considered
failed. [After some restorative cycling in early June, the 800A unit
operated from 6/7 - 6/17, then rapidly lost its capacity.  The
remaining seven batteries in the SM are able to maintain positive
power balance, and negotiations are underway with Khrunichev to use
the spare FGB battery in case it should be needed.]

Moscow continues to analyze data from the failed Klest-140ST-M
television camera mounted externally on the SM aft end, pointing
rearward (+X direction for SM).  Upon activation during a recent
routine check, an electrical short occurred which appears to have
been caused by the camera's cabling inside the module, not the camera
itself.  [Good connectivity measurements by Malenchenko on 6/23 of
the wiring, cable network and connections to the SUBA (onboard
equipment control system) have been received on the ground and are
being analyzed.  This camera is intended to be used for rendezvous
and docking of the European ATV (automated transfer vehicle) late
next year at the SM aft port.  If the camera itself is at fault, it
would need to be replaced via an EVA/spacewalk.]

Science Officer Ed Lu recommended the ground to look into the
possibility of a minor Flight Rule revision regarding usage
restrictions on the Lab nadir window during XPOP attitude.  A slight
change may result in a considerable increase in viewing angles and
viewing opportunity. 

Today's CEO (crew earth observation) targets, limited in the current
XPOP attitude by flight rule constraints on the use of the Lab
nadir/science window, and including the targets of the Lewis & Clark
200-year memorial locations, were Western Mediterranean Haze (reports
of reduced visibility in coastal cities of Spain:  looking left of
track for haze over the Med), Eastern Mediterranean Haze (looking
left and right for industrial haze in the Adriatic Sea off Venice,
where visibility is reduced today as high pressure persists), Berlin,
Germany (cloudfree zone over north-central Europe:  Berlin is
immediately north of track and hard to see despite its great area,
due to the great number of trees.  We are trying to take advantage of
optimal midsummer lighting at the top of the orbit), St. Louis,
Missouri (nadir and a touch left), Detroit, Michigan (nadir pass),
Eastern Mediterranean Dust (early morning sun and gusty winds should
allow blowing dust to be documented off the Libyan coast, left and
right of track), Los Angeles, California (nadir pass), Las Vegas,
Nevada (nadir pass), The Dalles (LEWIS & CLARK SITE:  Crew was to try
mapping the lower Columbia River.  Of particular interest is the area
known as The Dalles, a great southward arc in the river before it
cuts through the Cascade Range), Mekong River Delta (looking right
for views of the delta.  Even obliques are useful due to the power of
the 400 mm lens.  Changes in land use and coastline patterns are the
objects of interest), Gulf of Maine plankton (ISS pass tracked along
the southern side of the gulf: looking left for any color variation
denoting spring plankton growth), and Lower Amazon River Basin
(looking right for the islands of the estuary.  Coastline change,
rapid island migration and the extent of water color change out into
the Atlantic Ocean are of interest [Amazon discharge reduces
salinities in the ocean in an area as large as the Mediterranean]).
