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 at about 1:35 p.m. EDT 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.
