KENNEDY SPACE CENTER, FLA. - In the Orbiter Processing Facility, STS-114 Mission Specialist Wendy Lawrence looks closely at Discovery’s wing leading edge. The leading edge panels of the orbiters’ wings have 22 Reinforced Carbon-Carbon panels, made entirely of carbon composite material. The molded components are approximately 0.25-inch to 0.5-inch thick. Lawrence and other crew members are at KSC for Crew Equipment Interface Test activities. During CEIT, the crew has an opportunity to get a hands-on look at the orbiter and equipment they will be working with on the mission. Return to Flight Mission STS-114 will carry the Multi-Purpose Logistics Module Raffaello, filled with supplies for the International Space Station, and a replacement Control Moment Gyroscope. Launch of STS-114 has a launch window of May 12 to June 3.
