*International Space Station Status Report #04-26*
*3 p.m. CDT, Friday, May 21, 2004*
*Expedition 9 Crew*

Aboard the International Space Station, the Expedition 9 crew closed out 
its first month in space with a busy week of spacewalk preparations, 
including a spacesuit dress rehearsal.

During the check of U.S. spacesuits, they discovered a problem with the 
cooling system for Commander Gennady Padalka's suit. As a result, 
troubleshooting and further checks are planned. The suit checkout was 
conducted in preparation for a spacewalk by Padalka and Science Officer 
Mike Fincke that will replace a failed power controller on the Station's 
truss. The repair is expected to restore power to a Control Moment 
Gyroscope (CMG) which lost power in April. Two other CMGs on the Station 
continue to operate well and are controlling the complex's orientation. 
The spacewalk is now expected to take place no earlier than June 16.

The suit checkout was planned to last about seven hours Wednesday, but 
it was cut short when Padalka reported no cooling. He reported small 
bubbles and froth in the water that is supposed to circulate through 
lines to provide the cooling. On Friday, Padalka and Fincke drained and 
replaced the water in the cooling system of Padalka's suit. On Saturday, 
they are scheduled to check Padalka's refilled suit cooling system to 
verify that water will circulate. If needed, they also may test the 
operation of a check valve in the system.

During the Wednesday dress rehearsal, the cooling system for Fincke's 
suit also experienced brief problems, but a sticky valve was quickly 
identified as the likely cause and it is not considered a concern for 
his suit's operation.

If the troubleshooting is successful on Padalka's suit, several steps 
remain before the spacewalk plans are finalized, including another U.S. 
spacesuit dress rehearsal. If needed, the spacewalk could be done in 
Russian Orlan spacesuits.

Also this week, Station ground controllers fired the ISS Progress 13 
engines for 11 minutes, boosting the Stationís altitude by 2.3 statute 
miles and adjusting its inclination by one one-hundredth of a degree. 
ISS Progress 13 is to undock from the Station at 4:19 a.m. CDT Monday, 
clearing the way for the arrival of the new ISS Progress 14. ISS 
Progress 14 is scheduled to launch at 7:34 a.m. CDT Tuesday from the 
Baikonur Cosmodrome in Kazakhstan. The new Progress will dock up to 
Zvezda at 8:55 a.m. CDT Thursday, an event that will be broadcast live 
on NASA Television.

In addition to fuel, food and supplies, the Progress 14 will bring new 
U.S. spacesuit gloves, sized specifically for Padalka and Fincke, as 
well as other suit components.

The crew also continued science work this week, conducting body scans 
using an ultrasound device. This is part of a research program to 
determine if minimally trained crewmembers can perform these advanced 
examinations with the assistance of a doctor in Mission Control. After 
computer-based training last week, the crew spent two sessions this week 
with body scans including scans of the elbow, knees, abdomen and chest.

The crew also replaced the hard drive in the Space Acceleration 
Measurement System, a system that provides data for a research program 
measuring how small vibrations may affect nearby sensitive experiments 
such as crystal growth studies.

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: http://spaceflight.nasa.gov/

The next ISS status report will be issued on Tuesday, May 25, after the 
launch of the ISS Progress 14 vehicle, or sooner if events warrant.
