This is a list of Tracking and Data Relay Satellites. TDRS spacecraft are operated by the United States National Aeronautics and Space Administration, and are used for communication between NASA facilities and spacecraft,[1] including the Space Shuttle, Hubble Space Telescope, and International Space Station.

As of 5 February 2014, seven of the TDRS satellites launched were operational, one (TDRS-L) had not yet entered service, one (TDRS-3) had been retired, two (TDRS-1 and TDRS-4) had been retired, and one (TDRS-B) had been lost in a launch failure.[2][3]
