According to the China Manned Space Engineering Office, at 8:56 on September 16, 2021, Beijing time, the Shenzhou 12 manned spacecraft was successfully separated from the space station's sky and core modules.
Up to now, the Shenzhou 12 astronaut crew has worked and lived in the space station complex for 90 days, setting a record for Chinese astronauts’ space residence time in a single mission.
Before the separation, the astronaut crew, with the cooperation of ground scientific and technical personnel, completed the pre-evacuation tasks such as setting the state of the space station assembly, sorting and downloading experimental data, and clearing and transferring the orbiting materials.
