*International Space Station Status Report #05-60*
*9 a.m. CST, Friday, Dec. 9, 2005*
*Expedition 12 Crew*

Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev 
focused on keeping the International Space Station in good working 
condition this week as managers reviewed plans for the change out of 
cargo vehicles at the complex.

On Monday, McArthur finished repairing an atmospheric contaminant 
monitor, called a Volatile Organic Analyzer (VOA), in the Destiny Lab. 
He replaced thermal fuses in the device, which measures amounts of gases 
in the cabin air. He is scheduled to replace a circulation fan for the 
rack the unit is housed in on Friday. He will activate and check the 
apparatus next week.

In the Russian segment, the crewmembers performed routine cleaning of 
the smoke detectors in the Zarya module. Tokarev repaired air ducts to 
improve airflow into the U.S. segment. In addition, Tokarev installed an 
adjustable fan with mufflers in the sleeping quarters to reduce the 
amount of noise the fan produces.

McArthur recorded a brief explanation of the space station's solar 
panels as part of NASA's educational programs. The curriculum-based 
activities in space by the crew are planned to demonstrate the basic 
principles of science, math, physics, engineering and geography. The 
programs show students how familiar objects on Earth may behave 
differently in weightlessness. The videotaped session will be 
incorporated into educational products that NASA will make available for 
use in classrooms.

McArthur updated the operating software of the five racks designed to 
house science experiments in the Destiny lab. He also prepared the 
canisters of a materials exposure experiment for installation on the 
outside of the complex during the next Space Shuttle mission.

Both crewmembers spent time this week rounding up unneeded equipment and 
trash for disposal in the ISS Progress 19 cargo craft now docked to the 
aft port of the Zvezda module. They also removed the Progress vehicle’s 
Kurs automatic docking system. The unit will be returned to Earth for 
refurbishment and reuse.

Station managers are reviewing a proposed change in the plan to undock 
the Progress Dec. 20. The new plan would leave the Progress attached to 
the station for a few more months, allowing the crew additional time to 
use it for trash disposal and to use up its oxygen and fuel supplies.

The next cargo vehicle, ISS Progress 20, launches Dec. 21 from the 
Baikonur Cosmodrome in Kazakhstan. If the new plan is approved, Progress 
20 would dock to the Pirs Docking Compartment Dec. 23. It will bring 
almost three tons of food, water, fuel, oxygen, air, spare parts and 
holiday gifts to the outpost.

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


The next ISS status report will be issued on Friday, Dec. 16, or 
earlier, if events warrant.
