Tianlian II-04, China's second-generation geosynchronous orbit data-relay satellite, will provide data relay and TT&C (telemetry, tracking and command) services for manned spacecraft such as spaceships and space stations, for medium and low-Earth-orbit resource satellites, and TT&C support for spacecraft launches.

This was the 565th flight mission of the Long March carrier rocket series.
