This is a list ofTracking and Data Relay Satellites. TDRS spacecraft are all ingeostationary orbit and are operated by the United StatesNational Aeronautics and Space Administration, and are used for communication between NASA facilities and spacecraft,[1] including theSpace Shuttle,Hubble Space Telescope, andInternational Space Station.
As of 1 March 2019, 12 of the TDRS satellites launched were operational, two (TDRS-3,TDRS-5) had been placed in storage, two (TDRS-1 andTDRS-4) had been retired, and one (TDRS-B) had been lost in alaunch failure.[2][3][4]
