TDRS-12, known before launch as TDRS-L, is an American communications satellite operated by NASA as part of the Tracking and Data Relay Satellite System. The twelfth Tracking and Data Relay Satellite, it is the second third-generation spacecraft to be launched, following TDRS-11 in 2013.
== Spacecraft == TDRS-12 was constructed by Boeing, based on the BSS-601HP satellite bus. Fully fueled, it has a mass of , with a design life of 15 years. It carries two steerable antennas capable of providing S, Ku and Ka band communications for other spacecraft, with an additional array of S-band transponders for lower-rate communications with five further satellites. The satellite is powered by two solar arrays, which produce 2.8 to 3.2 kilowatts of power, while an R-4D-11-300 engine is present to provide propulsion.
