Technicians who moved one half of the payload fairing into place over NASA's Tracking and Data Relay Satellite, TDRS-K, pose inside the Astrotech payload processing facility in Titusville, Fla., near NASA’s Kennedy Space Center. Launch of the TDRS-K on a United Launch Alliance Atlas V rocket is planned for January 29, 2013. The TDRS-K spacecraft is part of the next-generation series in the Tracking and Data Relay Satellite System, a constellation of space-based communication satellites providing tracking, telemetry, command and high-bandwidth data return services.
