KENNEDY SPACE CENTER, FLA. - A worker on Launch Pad 39B at NASA Kennedy Space Center walks alongside the track of the Rotating Service Structure as it begins rolling back from its position around Space Shuttle Discovery. Rollback of the RSS is a major preflight milestone, typically occurring during the T-11-hour hold on L-1 (the day before launch). Discovery is scheduled to lift off on the historic Return to Flight mission STS-114 at 10 39 EDT July 26 with a crew of seven. On the mission to the International Space Station the crew will perform inspections on orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure.
