TDRS-5 spacecraft

Geostationary tracking and data-relay satellite

TDRS-5 spacecraft was a about 5,000 pounds (2,270 kilograms) with deployed antennas NASA communications platform carrying s-band multiple-access array, steerable s-band and ku-band single-access antennas, telemetry, command, and station-keeping systems. Atlantis deployed TDRS-E, later TDRS-5, adding S-band and Ku-band forward and return services that strengthened scheduling flexibility and redundancy for a growing fleet of human and robotic spacecraft.
