In the third month of a six-month mission, the International Space 
Station Expedition 12 crew worked this week on science experiments, 
maintenance and the setup of hardware for future activities. After a 
light duty weekend, Commander Bill McArthur and Flight Engineer 
Valery Tokarev began the week with science tasks. 

McArthur, the NASA station science officer, worked with the Human 
Research Facility 2, setting up a refrigerated centrifuge for 
biological samples for future experiments. He also conducted 
experiments with the Binary Colloidal Alloy Test-3. It uses small 
particles called colloids to study fundamental physics. It gathers 
data that may provide insight into a wide range of applications, from 
the development of new pharmaceuticals to new rocket engines. 

McArthur also inspected samples for the InSPACE magnetic materials 
experiment. The investigation studies the physics of magnetic 
particles in a fluid to gain insight into the processes used in many 
electromechanical applications on Earth. McArthur also repaired a 
trace contaminant monitor in the Destiny Lab. The monitor measures 
the amount of gases in the cabin air. He replaced thermal fuses and 
will activate and check the device next week. 

During the week, the crew performed a variety of maintenance 
activities, labeled fire ports in the Unity Node, conducted an 
inventory of water containers and performed preventative maintenance 
on a ventilation system in the Russian segment. McArthur took time 
out to talk to students at two schools via amateur radio, the 
Hawthorne Brook Middle School in Townsend, Mass., and the Ralph 
McCall School in Airdrie, Alberta, Canada. 

Tokarev worked with the docked Progress resupply spacecraft and 
repressurized the station atmosphere using oxygen from the craft. The 
Elektron oxygen generation system in the Zvezda Service Module was 
intentionally shut down last week to use the oxygen from the 

Tokarev continued unpacking the craft and loading it with unneeded 
gear. Propellant from the Progress tanks was transferred to station 
tanks on the Zarya module. Both crew members completed routine 
medical officer proficiency training. 

Station managers are evaluating a proposal from Russian engineers to 
delay the scheduled Dec. 20 Progress undocking. The proposal would 
leave the Progress attached to the station longer, allowing the crew 
additional time to use it for trash disposal and to use its oxygen 
supply. Regardless of whether the Progress is docked or undocked, 
launch and docking of the next Progress is Dec. 21 and Dec. 23. The 
new Progress will deliver food, water, fuel, air and holiday gifts 
for the crew. It will be the 20th Progress to go to the station.
