Launched on August 8, 2007, the top priority of mission STS-118 is to deliver and assemble the S5 truss segment to the International Space Station (ISS). The 11 + 3 day mission marks the 22nd shuttle trip to the ISS, and the 20th flight of space shuttle Endeavour. Canada's contribution is once again crucial. During the mission, astronaut Dave Williams, a veteran of shuttle mission STS-90, will set a Canadian record by spending over 19 h outside the space station during three scheduled spacewalks. In addition, Canadian-made robotics and sensor technologies will help ensure the success of the mission and the safety of the shuttle and crew.
