After the spacecraft enters orbit, it will carry out autonomous and rapid rendezvous and docking with the core cabin of Tianhe in accordance with the predetermined procedure. During the flight of the composite body, the astronauts will be stationed in the space and core module, complete a three-month in-orbit residency, carry out manipulator operation, exit activities, etc., verify the astronauts’ long-term stay in orbit, regeneration life insurance, etc. Key technology.
At present, the combination of Tianhe core module and Tianzhou-2 is operating in a near-circular docking orbit of about 390km. It is in good condition and meets the mission requirements for rendezvous and docking with Shenzhou 12 and the conditions for astronauts to be stationed.
