KSC-00pp0714

The logo for the Tracking and Data Relay Satellite (TDRS-H) is predominantly displayed on the fairing that will encapsulate the satellite for launch. The fairing is in KSC’s Spacecraft Assembly and Encapsulation Facility (SAEF-2) where TDRS is undergoing testing. The TDRS is scheduled to be launched from CCAFS June 29 aboard an Atlas IIA/Centaur rocket. One of three satellites (labeled H, I and J) being built in the Hughes Space and Communications Company Integrated Satellite Factory in El Segundo, Calif., the latest TDRS uses an innovative springback antenna design. A pair of 15-foot-diameter, flexible mesh antenna reflectors fold up for launch, then spring back into their original cupped circular shape on orbit. The new satellites will augment the TDRS system’s existing Sand Ku-band frequencies by adding Ka-band capability. TDRS will serve as the sole means of continuous, high-data-rate communication with the space shuttle, with the International Space Station upon its completion, and with dozens of unmanned scientific satellites in low earth orbit
