The Shenzhou XV mission crew entered the Tiangong space station on Wednesday morning. They were given warm hugs from their Shenzhou XIV peers already orbiting for nearly six months. Following the arrival of the Shenzhou XV spaceship, the Tiangong space station has developed into its largest size. As one of the largest space-based assets mankind has ever deployed in outer space, the station now consists of the Tianhe core module, the Wentian and Mengtian lab modules, the Shenzhou XIV and Shenzhou XV spacecraft as well as the Tianzhou 5 cargo ship.
