ISS On-Orbit Status 18 Nov 2002

All ISS systems continue to function nominally, except as noted previously
or below. Week 24 and Day 166 in space for Expedition 5.

After wake-up at the current sleep-shifted 11:00am EST, the crew completed
Kentavr ("Centaur") preparations, postponed from 11/11, for
their return to Earth. After the adjustment, CDR Valery Korzun tagged
up with a Kentavr specialist at TsUP. [The Russian Kentavr garments are
a protective anti-g suit ensemble to facilitate the return of a long-duration
crewmember into the Earth gravity. Consisting of shorts, gaiters, underpants,
jersey and socks, it acts as countermeasure for circulatory disturbance,
prevents crewmember from overloading during descent and increases orthostatic
tolerance during post-flight adaptation. Sizing consists of adjusting
lacing on the outer side of the shorts and on the inner side of the gaiters
to achieve a tight fit.]

CDR Valery Korzun, FE-2 Sergei Treschev and FE-1/SO Peggy Whitson today
are occupied mostly with regular maintenance tasks in the Russian and
US segments.

Korzun started out, at 1:45pm EST, with demating BITS2-12 telemetry connectors
to allow changeout of two DS-7A smoke detectors (nos. 6 & 8) in the
Service Module (SM). He will then reconnect the BITS TMI and re-enable
fire detection mode on the controlling laptop.

Treschev is scheduled to work in the DC-1 docking compartment, changing
out its two dust filters and cleaning the grills of the V1 and V2 ventilators.

Later, CDR Korzun moves to the FGB cabin to replace the filters of its
PS1 & PS2 dust collectors, followed by cleanup of the removable screens
on the FGB’s three GZhT gas-liquid heat exchangers.

After lunch (6:30pm), Treschev is to switch absorption bed #1 of the
harmful impurities removal unit (BMP) to the 24-hr. regeneration cycle,
leaving channel 2 in Purify mode.

Sergei will then perform cleanup of the protective fan screens on the
TsV1 & TsV2 ventilators in the FGB.

FE-1/SO Peggy Whitson is scheduled for similar servicing tasks in the
US segment, conducting inspection and cleaning of bacterial filters and
smoke detectors (SDs) in the Node, Lab and Joint Airlock (AL). [After
the maintenance, the Node SD will not be enabled since it is suspect and
may generate a false alarm, and the AL SD is already off and will stay
off, since the CCAA (common cabin air assembly) air conditioner in the
AL is not running.]

Whitson will power up the EVARM (EVA radiation monitoring) reader and
conduct another pre-EVA background radiation reading from all twelve badges.
She will then restow the badges in the reader lid.

Afterwards, Peggy is to conduct the regular weekly inspection of the
RED (resistive exercise device), followed today by the monthly procedure
of tightening the RED bolts. Along with Valery, she is also scheduled
for the weekly maintenance of the TVIS treadmill, consisting of SLD (subject
load devices) inspection before and after the exercising crewmember is
harness-configured for the workout.

The crew again has time allotted for early prepacking and departure preparations
for 11A.

The daily physical exercise program is scheduled for all crewmembers.

The daily routine servicing tasks of SOSh life support systems maintenance,
IMS inventory delta file preparation for downlink, and Lab payloads status
checkup will be performed by Korzun, Treschev and Whitson, respectively.

Peggy Whitson has completed the procedures review for the upcoming removal
and replacement of the ASV valves of the CDRA carbon dioxide removal assembly,
once the spare valve sets have arrived with 11A.

The crew was notified of the very dynamic event of tomorrow’s Leonid
meteor "bombardment" of Earth, which will visibly peak over
Europe at 3:50 GMT on 11/19, i.e., 10:50pm EST on 11/18. This will be
the last major outburst of this meteor shower for us, at least until the
return of its parent comet, P55/Tempel-Tuttle, in about 30 years. [The
ISS crew, which has the best viewing platform, was advised to use the
Sony PD100 video camcorder, starting at 10:30pm, to record the shower
from the DC-1 EVA hatch window #1 (looking into flight direction), the
SM Transfer Compartment window, and the Lab nadir window. Meteor rates
are expected to be 500-1000 per hour. The comet’s discarded cloud of celestial
dust thawed from its icy body back in 1766 when the comet streaked around
the sun at about 75,000 mph. Each year in November, the Earth passes through
some debris left by Tempel-Tuttle, but this year’s passage should be extraordinary
since Earth passes through the big 1766 cloud itself like last year. As
it encounters the myriads of dust particles head-on, their fiery trails
seem to radiate from a point within the constellation Leo (the Lion),
and the annual showers are therefore called "Leonids".]

Today’s targets for the CEO (crew earth observation) program are Industrialized
SE Africa (ideal low-sun opportunity to shoot industrial haze, looking
both sides of track), Tuamotu-Austral Islands (crew was to focus on coral
reefs), Sydney, Australia (nadir and a touch right; ESC [electronic still
camera] requested), Jakarta, Indonesia (left of track on the N coast of
Java; ESC. In the crew’s line of sight, the smoking Papandayan Volcano
should have been visible inland. Also, ISS passed almost directly over
the famous Krakatau Volcano, an island situated in the narrow straight
between Java and Sumatra), Lagos, Nigeria (a touch left of track on a
coastal lagoon. It has been many weeks since the last good opportunity.
ESC), Industrialized SE Africa (aerosol buildup. Particular request: views
taken at the coast looking right of track back over the coastal lowlands
towards the mountainous plateau escarpment. Smog densities differ strongly
above and below the escarpment), and Johannesburg, South Africa (nadir
pass. Looking left and right to document the Witwatersrand metroplex,
the largest industrial complex south of the Sahara).
