The STS-112 emblem symbolizes the ninth assembly mission (9A) to the International Space Station (ISS), a flight which is designed to deliver the Starboard 1 (S1) truss segment. The 30,000 pound truss segment will be lifted to orbit in the payload bay of the Space Shuttle Atlantis and installed using the ISS robotic arm. Three space walks will then be carried out to complete connections between the truss and ISS. Future missions will extend the truss structure to a span of over 350 feet so that it can support the solar arrays and radiators which provide the electrical power and cooling for ISS. The STS-112 emblem depicts ISS from the viewpoint of a departing shuttle, with the installed S1 truss segment outlined in red. A gold trail represents a portion of the Shuttle rendezvous trajectory. Where the trajectory meets ISS, a nine-pointed star represents the combined on-orbit team of six shuttle and three ISS crew members who together will complete the S1 truss installation. The trajectory continues beyond the ISS, ending in a six-pointed star representing the Atlantis and the STS-112 crew.
