KENNEDY SPACE CENTER, FLA. - Viewed from a camera in the midst of Florida greenery across the marshy water, Space Shuttle Discovery leaps through billows of smoke and steam on Launch Pad 39B on the historic Return to Flight mission STS-114. Liftoff occurred at 10:39 a.m. EDT. This is the 114th Space Shuttle flight and the 31st for Discovery. The 12-day mission is expected to end with touchdown at the Shuttle Landing Facility on Aug. 7. On this 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.
