Tracking and Data Relay Satellite M (TDRS-M) is the last of three satellites that comprise the third generation of the TDRSS constellation. The name TDRS-M is temporary, as spacecraft in the series are given an alphabetical designation before launch which is then changed to a numeric one once on station in orbit. TDRS-M is expected to become TDRS-13 once in orbit.

The Tracking and Data Relay Satellite System, or TDRSS, is a fleet of geosynchronous communications satellites that form part of NASA’s Space Network. Introduced in the 1980s to support the Space Shuttle, TDRSS continues in service today, providing a relay for communications, scientific data, telemetry and commands between operators on the ground and spacecraft in Earth orbit – including the Hubble Space Telescope and the International Space Station.
