List of TDRS satellites
This is a list ofTracking and Data Relay Satellites.TDRS spacecraft are all ingeostationary orbitand 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-1andTDRS-4) had been retired, and one (TDRS-B) had been lost in alaunch failure.[2][3][4]
