Space Shuttle Endeavour approaches the International Space Station during mission STS-118 with the S5 truss section ready to be installed.

S5 at KSC

Description:

• The P5 and S5 trusses are connectors, which will support the P6 and S6 trusses, respectively. The P3/P4 and S3/S4 truss assemblies' length was limited by the cargo bay capacity of the Space Shuttle, so these small connectors are needed to extend the truss.
• The ITS-S5 short spacer is part of the 11-segment Integrated Truss Structure (ITS) which forms ISS's backbone with mountings for unpressurized logistics carriers, radiators, solar arrays and various other elements. It is the third starboard (right-side) truss segment to be delivered. It is attached to the Starboard 4 (S4) truss element. ITS-S5 is used primarily to connect power, cooling lines and serve as a spacer between the S4 and S6 photovoltaic modules. The Boeing-built segment measure 3.37 meters x 4.55 meters x 4.24 meters, weight 1,819 kg and cost $10,971,693. The girder-like structure is made of mostly aluminum and provides several extravehicular aids, robotic interfaces and ammonia servicing hardware.
• The P5 truss was installed on December 12, 2006 during the first EVA of Space Shuttle mission STS-116.

Mission details:

• Launch on August 8, 2007 at 22h36 UTC, from Kennedy Space Center LC-39A, by the Space Shuttle STS-118. Mated to the International Space Station's ITS truss on 11 August 2007 at 17h30 UTC.
