Default ISS On-Orbit Status, 25-04-2004

ISS On-Orbit Status 25 Apr 2004

All ISS systems continue to function nominally, except those noted
previously or below. During the night (~1:13am EDT) the station completed
31,000 revolutions of the Earth since FGB/Zarya launch. Day 5 of joint
Exp.8/Exp.9 operations. Ahead: Week 27 for Expedition 8 -- their last week
in space.

*Sunday* -- though not much of a rest day for the five station residents,
after their wake-up at midnight (EDT), followed by another demanding
15.5-hr. day (sleep: 3:30pm). But they must have felt good on receiving
more kudos on a "really good job with the payload and SSRMS ops yesterday".

Handover activities between Exp. 8 & Exp. 9 continued on schedule, with a
last-minute change for Mike Foale and Mike Fincke for resizing the onboard
EMU/spacesuits. Gennady Padalka and Alexander Kaleri worked Russian
experiments besides their handovers. [In his handover, Kaleri particularly
emphasized procedures (incl. "lessons learned") for rebooting the PACKET
laptop and ISS "Wiener" power laptop every morning, including
synchronization of the Matryoshka's BSPN payload server from the Wiener
after setting up the latter with the exact time as per the station clock,
working with Email on the PACKET laptop (receiving, printing, archiving,
copying), and working with photographs on the ŇĐ1 laptop (pictures of EVA,
Earth, service systems & devices, inside and PAO views, Uragan, personal,
etc.).]

VC6 FE-1 André Kuipers, on his FD7, again concentrated on his scheduled
payloads of the European "Delta" science package, today predominantly
featuring the experiment ARGES, for which he performed the manual Helical
Instabilities investigation on lamps 11-20 in the MSG (Microgravity Science
Glovebox). This completes ARGES, and the MSG was powered off. Other
experiments for Kuipers were ICE in its incubator, SAMPLE, MOUSE, MOP,
MUSCLE, and Seeds in Space. In addition, on his optional task list André
had the photographic activities of documenting his work and taking pictures
of Holland during suitable overflight passes. [An investigation is underway
why four of the six "Makita" batteries did not seem to charge properly in
support of CIRCA (and would not run the power tool), as reported by "Spanky"
Fincke.]

Foale and Fincke had two hours set aside for resizing three EMUs plus one
hour for a communications check. [The resizing of all three on-orbit EMUs
was necessary to prepare for an unscheduled EVA in support of the
replacement of the failed CMG-2 RPCM (remote power controller module). The
resizing, which involved EMUs #3011 for Fincke (EV1) and #3005 for Padalka
(EV2), plus EMU #3013, kept in stowage as backup, was entirely successful.
The subsequent comm check was to test both radios of #3011 on high and low
frequency as well as hardline. After the midterm checkout a data drop out
had been noticed that might be tied to the transition procedure between comm
modes. All modes operated as expected. The switch from Alternate to
Primary radio again experienced a delay of ~4 min, but good data was
received in all modes. It was determined that this delay is peculiar to the
data processing software. The crew commented that the suits look really
good and that the task was excellently suited for Mike Fincke to familiarize
himself with the "Quest" Airlock.]

Sasha Kaleri worked on the Russian segment (RS) air ventilation system to
restore the nominal IMV (intermodule ventilation) configuration up to the
4/29 departure of 7S/Soyuz-213 from the DC-1 docking module. [The task
involved disconnecting an air duct from the SKV-1 air conditioner,
re-installation of a ventilation grille in its nominal location and stowing
the removed air duct.]

Mike Fincke performed the daily leak check of the Lab window's inter-pane
volume, using the "Aeolus" scopemeter with pressure probe. The pressure at
1:40am EDT this morning was 58.8 Torr (yesterday @ 1:55am: 28.5 Torr).

Fincke then floated through the station to set up the 16 new RAMs (radiation
area monitors) that had arrived with Soyuz-214. After the deployment, he
took digital pictures to document the placements.

FE Sasha Kaleri set up the equipment for the Russian MBI-2 Deuraz
("Diuresis") experiment, to be conducted by him tomorrow and on Tuesday.
[Deuraz requires Sasha tomorrow to record toilet use time in the morning,
perform urine sample collections throughout the day, and log meal and fluid
intake on a record card. Additional work, to be completed on Tuesday,
consists of collecting his venous blood samples, followed by centrifugation
to separate the blood into cells and plasma, and finally closeout and
stowage.]

Kaleri used the IPD Draeger tube air samplers to sample for ammonia (NH3),
collecting samples in the SM. [NH3 sampling is regularly done before and
after the MBI-2 Deuraz experiment.]

Also, the MCA (major constituents analyzer) was activated for a "zero"
calibration and data take, after exhibiting a "MCA Pressure Out of
Tolerance" caution that cleared within 10 seconds. MCA has now been placed
back in LEM (Life Extending Mode).

CDR-9 Padalka attended to the daily routine maintenance of the SOZh
environmental control & life support systems in the SM and prepared the
daily "delta" file for updating the IMS (inventory management system)
database.

Alex Kaleri worked on the electronics of the GTS (Global Timing System),
replacing the used flash card with a new one, delivered on 8S. [The
electronics systems of the Russian/German GTS (Global Timing System) are
installed in the SM, with two transmitters intended to broadcast a time
signal at 400.1 MHz (1 watt) and 1428 MHz (0.5 watt) straight downward
(nadir) for worldwide clock synchronization. The system has been
experiencing problems for a long time.]

Sasha also performed his regular daily inspection of the BIO-5 Rasteniya-2
("Plants-2") experiment which researches growth and development of plants
under spaceflight conditions in the Lada-4 greenhouse.

Later, Kaleri also set up the equipment for the Russian MBI-11 Gematologia
("Hematology") experiment, which he will undergo tomorrow. [MBI-11
investigates the decrease in red blood cell mass during long duration
exposure to micro-G. The test requires drawing blood samples for analysis
with the special "Erythrocyte" kit.]

Gennady Padalka conducted another run with the Russian Fluorestsentsiya
("Fluorescence") experiment using the FORREY apparatus, again being
photographed by Kaleri during the activity with the Nikon D1. Begun on
4/22, the experiment is performed daily until 4/28.

André had another live television event with media in Holland, during which
he was interviewed by TV journalists Frits Barend and Henk van Dorp.

A second media event for Kuipers was a Dutch radio interview on "NOS Radio 1
Journaal" by journalist Sander van Hoorn.

During today's experiment session with the ARISS ham radio equipment in the
SM, Kuipers chatted with students of the "Saltoschool Hanevoet" elementary
school, "Sint Joriscollege" middle school and the Technical University of
Eindhoven, assembled at Hanevoet School in Eindhoven, Netherlands.

The two Expedition crews performed the full regimen of physical exercise on
RED (resistive exercise device) and TVIS (treadmill with vibration isolation
and stabilization), and Foale took Fincke through a familiarization session
of scheduled RED inspection as well as the monthly tightening of the RED's
bolts.

Yesterday's Robotics handover and training operations with the Mobile
Servicer System (MSS) went well, introducing Gennady Padalka and Mike Fincke
to the on-orbit hardware and Ground-as-M2 operations (for a 2-person crew).
[The ops went as planned except for a problem encountered during the grapple
exercise: Near the end of the "rigidize" step during the grapple at MBS
PDGF-3 (Mobile Base System/Power & Data Grapple Fixture #3), the capture
aborted and the SSRMS "safed" itself due to a lower than required tension
value indicated by the carriage load cell. The crew performed a manual
procedure to recover from the capture abort and completed the grapple
successfully.]
