The craft then moved to the front docking port and completed a computer-orchestrated rendezvous and docking. The whole process lasted about four hours, the CMSA said.

It also said that the combination of Tianhe and Tianzhou-2 is in good condition, waiting for docking with the Tianzhou-3 cargo craft and the Shenzhou-13 manned spaceship.
