List of TDRS satellites

Summary

Location of TDRS as of 26 May 2020
Location of TDRS as of March 2019

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 1 March 2019, 12 of the TDRS satellites launched were operational, two (TDRS-3, TDRS-5) had been placed in storage, two (TDRS-1 and TDRS-4) had been retired, and one (TDRS-B) had been lost in a launch failure.[2][3][4]
