After an early morning rollout, Space Shuttle Atlantis, atop the Mobile Launcher Platform, passes by the American flag as it moves through the gate at the launch pad. After being stacked with its solid rocket boosters and external tank, Atlantis began its rollout to Launch Pad 39B at 2:27 a.m. EDT in preparation for launch to the International Space Station. The Shuttle arrived at the Pad and was hard down at 9:38 a.m. Launch is scheduled no earlier than Oct. 2 for mission STS-112, the 15th assembly flight to the International Space Station. Atlantis will carry the S1 Integrated Truss Structure, which will be attached to the central truss segment, the S0 truss, during the mission.
