CAPE CANAVERAL, Fla. – In the Hangar AE Mission Director's Center at Cape Canaveral Air Force Station in Florida, NASA and contractor managers and engineers monitor progress of the countdown for the launch the agency's Tracking and Data Relay Satellite, or TDRS-L, spacecraft atop a United Launch Alliance Atlas V rocket. The TDRS-L spacecraft is the second of three new satellites designed to ensure vital operational continuity for NASA by expanding the lifespan of the Tracking and Data Relay Satellite System TDRSS fleet, which consists of eight satellites in geosynchronous orbit. The spacecraft provide tracking, telemetry, command and high bandwidth data return services for numerous science and human exploration missions orbiting Earth. These include NASA's Hubble Space Telescope and the International Space Station. TDRS-L has a high-performance solar panel designed for more spacecraft power to meet the growing S-band communications requirements. TDRSS is one of NASA Space Communication and Navigation’s SCaN three networks providing space communications to NASA’s missions.
