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.
