KENNEDY SPACE CENTER, FLA. -- The payload canister on its transporter leaves the Vertical Processing Facility. Inside the canister are the S5 truss, SPACEHAB module and external stowage platform 3, the payload for mission STS-118. They will be placed in the payload bay on Space Shuttle Endeavour when it arrives at the pad. The mission will be Endeavour's first flight in more than four years. The shuttle has undergone extensive modifications, including the addition of safety upgrades already added to shuttles Discovery and Atlantis. Endeavour also features new hardware, such as the Station-to-Shuttle Power Transfer System that will allow the docked shuttle to draw electrical power from the station and extend its visits to the orbiting lab.

JSC2006-E-43502 (October 2006) --- Computer-generated artist's rendering of the International Space Station after flight STS-118/13A.1. Third starboard truss segment (S5) is delivered and installed. External Stowage Platform 3 (ESP3) is installed on top of the P3 truss segment. Pressurized Mating Adapter-3 (PMA-3) moves to Unity node nadir port.

As the construction continued on the International Space Station (ISS), STS-118 Astronaut Rick Mastracchio and Canada Space Agency representative Dave Williams (out of frame), participated in the first session of Extra Vehicular Activity (EVA) for the mission. During the 6 hour, 17 minute space walk, the two attached the Starboard 5 (S5) segment of truss, retracted the forward heat rejecting radiator from the Port 6 (P6) truss, and performed several get ahead tasks.
