ISS On-Orbit Status 17 June 2002

All ISS systems continue to function nominally,
except as noted previously. We are off to an excellent start
with Expedition 5.

After wakeup at 2:00 am EDT, the new station crew had their first
work day, though still with light duty.

CDR Valery Korzun completed a 3.5-hour job of periodic maintenance of
the station’s ASU toilet system, changing out the replaceable
elements such as hoses, a receptacle, T-joint, elbow fitting and
filter insert with new parts delivered on Progress 7P and 6P. 
The old components were stowed for subsequent disposal.

FE-1 Peggy Whitson worked on the payload SSC (space station
computers), reloading them with new code including the crew specific
software programs and reconfiguring the network accordingly. 
This task is done regularly within the first two weeks of a new crew
being on board.

FE-2 Sergey Treschev unpacked and stowed UF-2 cargo items placed in
the interim staging areas, particularly in the Node, during the
docked period.

Treschev also completed a familiarization session with the U.S. video
camcorder equipment, reviewing the camcorder procedures and
configuring its cabling in the Node for video downlink of
Progress-257 (7P) stowage operations later this week.  Two
camcorder batteries were to be retrieved from stowage, in preparation
for the time of video downlink.

The crew had 1.5 hours set aside on their schedule for ISS
orientation, i.e., to adjust to living in their new
environment.  This is being maintained for the first two weeks
after UF-2 undock.

Routine maintenance tasks today were SOSh life support systems
servicing by Treschev, Lab payloads status check by Whitson, and
inspection of the BRPK-2 water condensate separator by Korzun. 
Today’s IMS delta file updating was deferred due to the SSC reload by
Whitson.

Korzun and Treschev had a session with the Russian Diatomeya ocean
observation program on their task list for today.  [Objective
was to look for and image seawater bloom features (brown, turquoise
and green spots and bands) in the bioproductive waters of the Pacific
Ocean (California Current) and Atlantic Ocean (North Atlantic
Current, research area of the Research Ship "Academician
Joffe"), as well as in the eastern portion of the Black
Sea.  Instruments used are an SLR NIKON F5 camera (focal length
80 mm) and a Sony PD-1P digital camcorder for panoramic views.]

Also on the Russian task list were observation and photo sessions
for the Uragan ("hurricane") earth viewing program. 
[Today’s targets included Sakhalin Island, Medvezhy Glacier, Altai
Mountains, Lake Baikal (south shore), Bazaro-Karabulak agricultural
test range (Saratov province), Mounts Aksai and Ilek (Stepnoi
district), quarries near Leipzig and Dresden, Berlin, Potsdam, and
Warsaw.]

STS-111/Endeavour landing was called off today for both
landing opportunities at KSC due to inclement weather.  The
alternate landing site EAFB (Edwards Air Force Base) also was closed
due to excessive winds.  Shuttle program is now look/:8at a
landing tomorrow at KSC at 11:55am EDT (deorbit burn: 10:47am) on
Orbit 200, with an alternate opportunity at 1:31pm EDT (deorbit
12:24pm) on Orbit 201.  Today is Flight Day 13 for STS-111 and
Day 194 in space for the returning Expedition 4 crew (189 days on
board ISS).
