PORT CANAVERAL, Fla. – The United Launch Alliance barge Delta Mariner arrives at Port Canaveral, Fla. delivering the Centaur stage of the launch vehicle that will boost the Tracking and Data Relay Satellite-K, or TDRS-K, into Earth orbit atop an Atlas V rocket. After off-loading, the Centaur will be transported to the Atlas Spaceflight Operations Center, ASOC, at Cape Canaveral Air Force Station to begin processing. 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.
