The STS-118 patch represents Space Shuttle Endeavour on its mission to help complete the assembly of the International Space Station and symbolizes the pursuit of knowledge through space exploration. The flight will accomplish its ISS 13A.1 assembly tasks through a series of spacewalks, robotic operations, logistics transfers and the exchange of one of the three long-duration expedition crew members. On the patch, the top of the gold astronaut symbol overlays the starboard S-5 truss segment, highlighting its installation during the mission. The flame of knowledge represents the importance of education, and honors teachers and students everywhere. The seven white stars and the red maple leaf signify the American and Canadian crew members flying aboard Endeavour.
