The Expedition 15 crew and the visiting STS-118 crew continue joint 
operations aboard the International Space Station.

Since the seven STS-118 astronauts arrived on Aug. 10, the station has 
grown in size and received a new attitude control gyroscope during two 
spacewalks. The Starboard 5 (S5) truss segment was attached Saturday 
during STS-118ís first spacewalk. The S5 will serve as a spacer segment 
between the Starboard 4 and 6 (S6) segments. The S6 and its solar arrays 
will be attached during a future shuttle mission.

During Mondayís spacewalk, a faulty control moment gyroscope (CMG) was 
replaced. The station has four CMGs that control its orientation in 
space. They are located in the Z1 truss. Two more spacewalks will take 
place during STS-118ís stay at the station.

In other activities, the two crews have been transferring cargo between 
Endeavour and the station. STS-118ís stay at the station is slated to 
wrap up when Endeavour undocks Aug. 20.
