EXP 13 ISS STATUS REPORT #06-30 - 23 JUNE 2006


*International Space Station Status Report #06-30*
*1 p.m. CDT, Friday, June 23, 2006*
*Expedition 13 Crew*

The International Space Station crew this week bid farewell to one cargo 
craft and prepared for the arrival of another. The crew also continued 
to prepare for the arrival of the Space Shuttle Discovery, which is set 
for launch July 1.

On Monday, Pavel Vinogradov and Jeff Williams watched as the ISS 
Progress 20 cargo vehicle automatically backed away from the station's 
Pirs docking port, making room for the next one's arrival. The new 
Progress is scheduled to launch from the Baikonur Cosmodrome at 10:08 
a.m. CDT June 24 and dock to the station at about 11:30 a.m. CDT June 
26. It will bring about 2.5 tons of equipment and supplies to the 
orbiting outpost.

Vinogradov took a refresher course on the Toru manual docking system 
Monday. Vinogradov would use the system to guide the cargo craft in the 
event its primary automated docking system did not function properly.

Throughout the week the station crew also prepared for Discovery's 
anticipated arrival. On Tuesday, Vinogradov and Williams reviewed the 
timeline of activities for the shuttle mission and held a conference 
with mission experts on the ground. On Friday, the crew continued to 
prepare U.S. spacesuits that will be used during the shuttle visit.

They also continued to pack equipment that will be returned to Earth on 
Discovery. On Wednesday, Williams installed the centerline berthing 
camera system in a window of the station's Unity connecting module. The 
camera view will assist with the attachment of a pressurized logistics 
module named Leonardo, which will be carried aboard Discovery to that 
module's port. The Leonardo module will be attached to Unity for 
unloading and reloading during the mission. It will be loaded in 
Discovery's cargo bay for the trip home.

Also on Wednesday, Vinogradov worked with the Russian experiment that 
studies self-propagating combustion materials. The investigation looks 
at mechanisms for forming high-porosity, heat-resistant, thermal 
insulating materials for spacecraft.

Williams spent more than three hours Thursday on station robotic arm 
activities, first training with a simulation program on a laptop 
computer and then exercising the arm itself. Supported by flight 
controllers on the ground, he moved the Canadarm2 in much the same way 
he will during Discovery's visit. He left it parked in position for 
Discovery's arrival.

While Williams worked with the robotic arm, flight controllers noted 
elevated spin motor command currents and vibrations on one of the 
station's four control moment gyroscopes, "CMG 3." The indications 
returned to normal several hours later, and the gyroscope has continued 
to perform normally.

The next station status report will be issued on Saturday, June 24 
following the ISS Progress 22's launch. For more about the crew's
