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-118’s 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 Monday’s 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-118’s stay at the station.

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