Expedition 15 Commander Fyodor Yurchikhin and Flight Engineers Oleg 
Kotov and Clay Anderson continue joint operations aboard the 
International Space Station with the STS-118 crew, which arrived at the 
International Space Station Aug. 10. STS-118’s stay has featured three 
spacewalks to continue the on-orbit construction of the station.

In addition to the seven STS-118 astronauts, Space Shuttle Endeavour 
carried the Starboard 5 (S5) truss segment to the station and STS-118 
spacewalkers installed it Aug. 11. The S5 truss segment is part of the 
station’s Integrated Truss Structure that will eventually be the length 
of a football field and contain four sets of solar arrays.

The station received a new control moment gyroscope (CMG) on Monday 
during the second spacewalk. The station has four CMGs that are used to 
control its attitude in orbit. The new CMG replaced a faulty gyroscope 
that will return to Earth on a future shuttle mission.

On Tuesday, the International Space Station’s first component to go into 
space, the Zarya control module, passed the 50,000th orbit mark at 11:17 
a.m. EDT(1517 UTC). Zarya, which is Russian for “Sunrise,” was funded by 
the United States and built by Russia. It launched atop a Proton rocket 
from Baikonur Cosmodrome in Kazakhstan on Nov. 20, 1998.

The third spacewalk occurred Wednesday. It featured preparations for the 
relocation of the Port 6 truss from atop the station to the end of the 
Port 5 truss when STS-120 visits later this year. A fourth spacewalk is 
scheduled for Saturday.

In other activities, the two crews have been transferring cargo between 
Endeavour and the station.

The STS-118 astronauts are scheduled to exit the station on Sunday and 
undock Monday. STS-118 is the 22nd shuttle mission to visit the station.
