Already the largest human-made object orbiting the Earth, the
International Space Station continued its on-orbit growth spurt with the
addition of the Starboard 5 (S5) truss segment. The S5 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. The S5 is the newest piece of the station’s backbone,
called the Integrated Truss Structure, which will eventually span the
length of a football field and contain four sets of solar arrays.
Three more spacewalks will take place during STS-118’s stay at the
station. One of the tasks during the upcoming spacewalks is the
replacement of a faulty attitude control gyro. The two crews are also
transferring cargo between Space Shuttle Endeavour and the station.
Expedition 15 Commander Fyodor Yurchikhin and Flight Engineers Oleg
Kotov and Clay Anderson welcomed the seven-member STS-118 crew aboard
the station Friday at 4:04 p.m. EDT. The STS-118 crew arrived at the
station a couple of hours earlier when Space Shuttle Endeavour docked at
STS-118’s stay at the station is slated to wrap up when Endeavour
undocks Aug. 20.
*Command and Control Computer Shuts Down, Backup Takes Over*
The main command and control computer in the International Space
Station’s Destiny Laboratory shut down about 3:52 p.m. EDT Saturday. The
primary backup computer immediately took control and assumed the backup
duties. There was no impact to the spacewalk being conducted by the
STS-118 crew. Flight controllers are working to resolve the issue.
