ISS On-Orbit Status 24 Jun 2003

Part 1 of 2

All ISS systems continue to function nominally, except as noted
previously or below.  This is Week 8 of Increment 7.

After breakfast at 2:40am EDT, work plan review, and morning DPC
(daily planning conference) via S-band, CDR Yuri Malenchenko started
the day with the TV downlink of the geophysical GFI-1 Relaksatsiya
("relaxation") video footage which had not been completed
satisfactorily on 5/20.  [The downlink of the recorded footage was
initiated by the Russian SPP automated daily timeline system during a
Russian comm pass on Daily Orbit 3 (DO3).  The videocassette of the
experiment was then stowed.] 

In a 1.5-hr. maintenance task in the FGB (funktsionalnyi-grusovoi
blok), after the FGB cooling system was switched to Internal Loop #1,
Malenchenko removed the Loop #2 (VGK2-1) replaceable pump panel (SPN)
and installed  a new SPN unit delivered on 12P/Progress-259.

FE/SO Ed Lu meanwhile worked on the CSA-CP (compound specific
analyzer-combustion products) system in the Lab, resupplying the
equipment and its stowage kit with two new CSA-CP units with fresh
carbon monoxide (CO) and hydrogen chloride (HCL) sensors, ten new
battery packs, one new zero filter and two spare pump filters.  He
then deployed the new CSA-CPs outside the stowage kit in the open
environment and readied the old CSA-CP for subsequent data takes.
[CSA-CP is a toxicology monitoring device for early CO
detection/warning and post-fire decontamination.  It also checks for
HCl and other combustion products and contaminants.] 

Next, Lu conducted a "zero" calibration run on the CSA-CP, then
activated the device for 5-min. readings in SM and Lab before
deactivating it and attaching it at its regular location at the SM
port wall central post. 

A planned 1-hr. activity by Yuri Malenchenko to reconfigure
electronic cables in the SM to connect the Regul-OS antenna feeder
unit (AFU) to the antenna feed in a new arrangement was deferred.

The Science Officer had 2.5 hours for performing the scheduled
functional video downlink test of the HRF (human research facility)
Ultrasound equipment (UVND).  [Ed Lu's task had two main objectives:
First, setting up and activating the HRF Ultrasound (U/S), followed
by downlinking a series of video test pattern images to the ground so
that HRF specialists can assess real-time video image downlink
quality from the U/S.  Then, in an experiment of remote-guidance
telemedicine with privacy-protected access, Space Medicine
specialists at the JSC TSC (Telescience Support Center) were to guide
him via privatized audio channel through acquisition of a series of
human subject internal images, in order to assess the degree of
downlinked U/S video and still-image degradation from clinical
perspective.  The U/S equipment is part of HRF Rack 1, launched on
5A.1 in March 2001. Its applications include echocardiography,
abdominal U/S (deep organ), vascular U/S, muscle and tendon U/S,
transcranial U/S and U/S contrast studies.  The procedure was jointly
prepared and conducted by the JSC TSC, POC (Huntsville Payload
Operations Center), and MCC-H.] 

In the SM, Yuri Malenchenko performed a 2-hr. hardware upgrade on the
BRPK condensate separation and pumping units by replacing the old
pipe conduits, including safety valves, with new units.  [The latter
have no filters and use higher safety valve trip pressures.  Purpose
of the upgrade is to prevent unwanted flow of the fluid through the
bypass line during condensate transfer cycles.]

Yuri also completed the regular weekly checkout of the IP-1 air flow
sensors in the various RS hatchways and the passage between FGB and
Node. 

Ed Lu completed the periodic transfer of accumulated physical
exercise data files of the TVIS treadmill and RED resistive exerciser
to the MEC (medical equipment computer), for subsequent downlink to
the ground.  [The downloads are scheduled after more than four
sessions have been performed since the last session.]

Ed also conducted the daily routine maintenance of the SM's SOZh
environment control & life support system, while Yuri later prepared
the daily "delta" file for updating the inventory management system
(IMS).

At 11:50am EDT, both crewmembers participated in an interactive
televised PAO interview (Ku-band & S-band) with Spaceflightnow.com's
Steven Young. [The interview was taped for later placement on the
client's website, and also broadcast live on NASA-TV.  It focused
primarily on how the crew is spending its time onboard; the arrival
of Progress 11 and its deliveries; daily life aboard ISS; ability to
maintain the station with only two persons; thoughts on the recovery
from the Columbia accident, the future of international cooperation
for further development of ISS, and space tourism. Questions had also
been submitted by visitors to the website.] 

The crew completed their regular daily 2.5-h program of physical
exercise, on TVIS treadmill, RED expander and, for Yuri, on the
Russian VELO cycle ergometer with load trainer.

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 Tucson forest fire, AZ (Dynamic
event:  Many dozens of homes feared destroyed in the Catalina Mts.
north of Tucson as the nation's largest fire rages.  Looking right
for the smoke clouds moving northward. Nadir view of Phoenix),
Denver, Colorado (nadir view of the city  detectable immediately east
of the dark forested Front Range of the Rockies), Taiwan smog
(looking right of track for probable smog buildup on the heavily
industrialized west side of the island.  The west coast is often
invisible from space due to industrial haze.  A second series of
images, slightly overexposed, might reveal structure in the smog
mass [structure indicates varying density and transport direction]),
Angolan Biomass Burning (as light slowly improves on the descending
passes, conditions are ideal to document the more subtle smoke
loadings in the atmosphere over this most flammable part of the
globe.  Looking left for source fires in the dense Angolan savanna;
looking right for the views of this mass moving out into the Atlantic
Ocean.  The latter views--of the haze "exhaust" from the continent--
are being specifically requested by scientists), and Marietta,
Ohio (LEWIS & CLARK SITE(S):  Marietta is noted as the oldest
settlement on the Ohio River.  It is located about ten miles upriver
from Parkersburg, West Virginia, where the Muskingum River enters
from the north and the Ohio makes a large meander north [looking just
right of track].  In the summer of 1803, on their return to St.
Louis, Lewis and Clark stopped here for a visit.  It was one of the
few settlements they encountered on their way west). CEO images can
