China's first cargo spacecraft, Tianzhou 1, completed an automated fast-docking with Tiangong 2 space lab on 12 September at 23:58 h. Controlled from Earth, Tianzhou 1 began to approach Tiangong 2 at 15:24 h. It took six and a half hours to complete the fast-docking with the space lab. It was the third docking between the two spacecraft using fast-docking technology. Previously, it took about two days to dock. The experiment tested the cargo spacecraft's capability of fast-docking, laying a foundation for future space station building.
