     Aboard the International Space Station, the Expedition 9 
crew concentrated on a host of scientific experiments and 
routine systems maintenance work in a busy 13th week in 

Commander Gennady Padalka and NASA ISS Science Officer Mike 
Fincke conducted numerous biomedical experiments. They 
participated in a Russian experiment named "Profilaktika," 
which was designed to measure Padalka's cardiovascular 
condition while he pedaled on a bicycle in the Zvezda Service 
Fincke began working with the Fluid Merging Viscosity 
experiment. This physical science experiment is studying 
viscosity, a property that causes fluids to resist flowing 
because of the internal friction created as the molecules 
move against each other. Understanding the viscosity of 
molten materials is important for everything from designing 
laboratory experiments to industrial production.
Fincke also set up the Earth Knowledge Acquired by Middle 
school students (EarthKAM) hardware for another run. EarthKAM 
is available for students who submit image requests and 
conduct geographic research. The requests are uplinked in a 
camera control file to a laptop computer. The computer 
activates an onboard digital camera at specified times and 
receives the digital images for subsequent downlink.

Marshall Space Flight Center, can be found on the Payload 
Operations Center's Web site at:


The crew spent part of its week stowing trash in the Progress 
resupply craft docked to the far end of Zvezda. The unpiloted 
Progress will detach from the Station by Russian flight 
controllers on July 30 and deorbited to burn up in the 
Earth's atmosphere. A new Progress cargo ship is scheduled 
for launch from the Baikonur Cosmodrome in Kazakhstan on 
August 11 for a docking to the Station on August 14. It will 
carry food, fuel, water, and supplies for Padalka and Fincke 
and for the Expedition 10 crew that is scheduled to launch to 
the Station in October.

On Thursday, Russian flight controllers were unable to upload 
new software into the Zvezda's computers in preparation for 
next year's maiden launch of the unpiloted European Automated 
Transfer Vehicle (ATV) cargo ship that will operate in tandem 
with the Russian Progress vehicles. Russian specialists are 
analyzing what may have caused the unsuccessful upload and 
plan to try again next Wednesday. The computers are operating 
normally with the current load of software.

Earlier today, Padalka replaced a pump assembly in Zvezda 
that malfunctioned on Wednesday, causing the temporary loss 
of one of two redundant loops that provides cooling for 
Russian segment systems. The backup cooling system kept all 
Russian systems operating at the proper temperatures until 
the replacement work occurred. Both cooling loops are now 
working normally.

Padalka and Fincke also participated in a pair of simulated 
emergency drills on board to maintain proficiency in handling 
medical emergencies and the unlikely depressurization of the 
Station cabin.

Next week, Fincke plans to conduct additional troubleshooting 
work on U.S. spacesuits with help from Mission Control. The 
Extravehicular Mobility Units (EMU) have cooling problems, 
which have tentatively been traced to pumps that circulate 
water inside the suits. Fincke plans to remove and examine 
one of the pumps. Repair parts for the suits are to be 
launched next month aboard the next Progress supply craft.

The next spacewalk, using Russian Orlan suits, is planned for 
Aug. 3. During the spacewalk, the crew will retrieve science 
experiments, install others, and prepare the outside of the 
Zvezda module's docking port for next year's first flight of 
the ATV. Next week, the crew will begin preparations for the 
spacewalk and will review procedures for the excursion.
