*Expedition 12 Crew*

It was back to work this week for the Expedition 12 crewmembers after a 
long New Year's weekend that marked the halfway point in their six-month 
stay aboard the space station.

Commander Bill McArthur and Flight Engineer Valery Tokarev had a 
relatively quiet New Year's Day, celebrating with a Russian meal. They 
also took Monday off, talking with family and acquaintances. McArthur 
conducted ham radio contacts with schools on the ground during the week.

Dec. 31 was the first day of the second half of the crew’s stay aboard 
the station. McArthur and Tokarev will spend their 100th day in space on 

Earlier this week the crew worked to unload the cargo of the ISS 
Progress 20 cargo craft that docked to the Pirs Docking Compartment Dec. 
23. Progress 19 remains at the aft docking port of the Zvezda Service 
Module as the crew continues to use its oxygen to replenish the 
station's atmosphere. The Elektron system that provides the primary 
source for oxygen generation on the ISS will be reactivated next week 
after being deliberately shut off since mid-December.

McArthur engaged in computer training for the FOOT experiment this week. 
FOOT measures activity and pressure on a crewmembers’ legs and feet in 
microgravity to help scientists determine how long duration missions 
contribute to bone and muscle loss. He conducted a dry run to calibrate 
the experiment on Wednesday. McArthur also reconfigured power supplies 
to the station’s computers. Thursday, he worked with the Binary 
Colloidal Alloy (BCAT) experiment, which looks at the behavior in 
microgravity of fine particles suspended in a liquid. Paint, milk and 
ink are common examples of colloids.

Tokarev worked much of the week setting up the “Matryoshka” radiation 
detection experiment. It measures radiation levels to which the crew is 
exposed. Tokarev set up detectors around the station and spent time with 
a companion “Phantom" torso experiment, placing about 370 radiation 
detectors around the horizontally-sliced replica of the upper part of a 
human body. With that completed, Tokarev mounted the dummy torso in the 
Pirs Docking Compartment for data collection.

The week drew to a close with additional scientific experiments and the 
installation of a batteries in the U.S. spacesuits on board. Throughout 
the week, the crewmembers also exercised and performed station maintenance.

Information on the crew's activities aboard the space station, future 
launch dates, as well as station sighting opportunities from anywhere on 
the Earth, is available on the Internet at:


The next station status report will be issued on Friday, Jan. 13, or 
earlier if events warrant.
