The Tracking and Data Relay Satellite (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. Launch of the TDRS-K on the Atlas V rocket is planned for January 29, 2013. The first stage of the Atlas V rocket that will carry the Tracking and Data Relay Satellite, TDRS-K, into orbit has been erected at Cape Canaveral Air Force Station’s Space Launch Complex 41 in Florida.Photo Credit: NASA/Ben Smegelsky
