“TDRS-M, to be renamed TDRS-13 upon entry into service, is an American communications satellite operated by NASA as part of the Tracking and Data Relay Satellite System. The thirteenth Tracking and Data Relay Satellite, it is the third and final third-generation spacecraft to be launched, following the 2014 launch of TDRS-L.

TDRS-M was constructed by Boeing, based on the BSS-601HP satellite bus. Fully fueled, it has a mass of 3,454 kg (7,615 lb), 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.”

NASA dixit:

“On Friday, August 18, NASA launched the third in a series of three advanced, Tracking and Data Relay Satellites, known as TDRS-M, from Cape Canaveral Air Force Station, in Florida. This latest addition to the fleet will augment a space communications network that provides the critical path for high data-rate communication to a host of spacecraft including the International Space Station and its resupply vehicles, the Hubble Space Telescope and many of NASA’s Earth-observing fleet spacecraft.”
