*Expedition 9 Crew*

Success was the key word this week aboard the International Space 
Station as maintenance efforts by the Expedition 9 crew paid off on 
several major equipment items.

Early this week, NASA Flight Engineer and ISS Science Officer Mike 
Fincke performed the most complex spacesuit repair job ever conducted in 
flight on a U.S. spacesuit, replacing a water pump in the suit's cooling 
system. The four and a half hour replacement job on Monday was followed 
by several hours of tests on Tuesday. The tests showed the new pump 
worked perfectly, and engineers on the ground will now determine whether 
to declare the spacesuit usable in the future. If so, the Station would 
have a complement of two operational U.S. spacesuits. A third suit is 
aboard as well but has a cooling problem. However, a second spare water 
pump is aboard the Station in the event managers choose to attempt 
similar maintenance on the third suit.

Flight controllers lauded Fincke's work, relaying to him that such 
efforts provide not only a better understanding for future Station 
operations, but also important data for all future long duration space 
travels.

Also on Monday, Fincke replaced major components in one of the Station's 
exercise machines, a resistive exercise device that uses tension to 
simulate weights during a workout. He installed new canisters in the 
device, designed to be twice as durable as the previous canisters used 
for the machine. He then checked their operation with a workout, finding 
the device in excellent condition. Exercise is vital for the crew as one 
method of counteracting the effects of weightlessness on the body. The 
spare spacesuit pumps and exercise canisters were delivered to the 
Station aboard the Russian Progress cargo craft that arrived Aug. 14.

As this week progressed, Fincke and Station Commander Gennady Padalka 
turned their attention toward their fourth and final spacewalk, 
scheduled for next week. During the Sept. 3 spacewalk, they will use 
Russian spacesuits and exit the Russian Pirs airlock. Their work outside 
will include installing three antennas on the exterior of the Zvezda 
living quarters module that will aid the navigation of a new Station 
supply craft, called the European Automated Transfer Vehicle, during its 
maiden flight set next year. Other tasks include replacement of a pump 
panel on the Zarya module that is part of the Russian segment's cooling 
system; installation of guides for spacesuit tethers on Zarya handrails; 
and the installation of handrail covers near the Pirs hatch.

This week, Fincke and Padalka reviewed timelines for the spacewalk, 
gathered gear and checked the tools they will use. On Monday, they will 
power up their Orlan spacesuits to check their operation as they 
continue their preparations. The spacewalk on Friday will begin at 11:50 
a.m. CDT and last about six hours. The activities will be broadcast live 
on NASA Television, beginning at 10:30 a.m. CDT.

Other activities this week included a Wednesday evening reboost of the 
Station, firing thrusters on the Progress craft to increase the altitude 
of the complex by an average of about two and a half statute miles. The 
reboost moves the Station closer to the orbital altitude desired for the 
arrival of a Soyuz spacecraft and new crew in October. Another reboost 
is planned in September to complete the move. The Station's current 
orbit has a high point of about 230 miles and a low point of about 218 
miles.

On Monday and Tuesday, Station cameras operated by flight controllers 
recorded video of Typhoon Chaba as it moved quickly across the 
Philippine Sea with winds of 165 mph. Today, Fincke reported taking a 
still photo of Hurricane Frances in the Atlantic Ocean as the Station 
flew above the storm.

The next ISS status report will be issued on Friday, Sept. 3, after the 
spacewalk, or earlier if events warrant.
