KENNEDY SPACE CENTER, FLA. - Members of the Space Shuttle Discovery’s Return to Flight STS-114 crew are conducting a payload Crew Equipment Interface Test (CEIT) in the Space Station Processing Facility at NASA’s Kennedy Space Center, Fla. Seen here is Mission Specialist Andrew Thomas, looking at the Control Moment Gyroscope, part of the mission payload. The launch window for STS-114 is May 15 to June 3, 2005. During CEIT, the crew is inspecting the resupply stowage racks installed in the Italian-built Multi-Purpose Logistics Module Raffaello and performing tool and equipment interface checks with the Thermal Protection System (TPS) repair sample box, the Control Moment Gyroscope (CMG) and the External Stowage Platform-2 in preparation for the mission’s three scheduled spacewalks. The seven-member crew will fly to the International Space Station primarily to evaluate procedures for flight safety, including Shuttle inspection and repair techniques. The TPS repair sample box contains tile samples for the Detailed Test Objective (DTO) that will enable the crew to test new on-orbit TPS repair techniques. The CMG installed on the Lightweight Multi-Purpose Experiment Support Structure Carrier (LMC) is a replacement for an inoperable CMG on the International Space Station. The CMGs provide altitude control for the outpost keeping it properly oriented toward the Sun without use of rocket fuel. The ESP2 will carry replacement parts, known as orbital replacement units (ORU) to the Station. The platform will be deployed and attached to the Station’s airlock and will be used as a permanent spare parts facility.
