According to the China Manned Space Engineering Office, at 23:08 on November 29, Beijing time, the Long March 2 F Remote 15 carrier rocket carrying the Shenzhou 15 manned spacecraft ignited and launched at Jiuquan Satellite Launch Center. About 10 minutes later, the Shenzhou 15 manned spacecraft separated from the rocket and entered the scheduled orbit. The astronauts were in good condition and the launch was a complete success. All 12 launch missions in the key technology verification and construction phase of the space station have been completed. After the spacecraft enters orbit, it will conduct autonomous and rapid rendezvous and docking with the space station assembly according to the predetermined procedure, and the crew of Shenzhou 15 will rotate with the crew of Shenzhou XIV on orbit. During the working and living period of the space station, the astronaut crew will carry out several extravehicular activities to complete various tasks such as installation, commissioning, maintenance and repair of on-board and extravehicular equipment, assembly management, space science and technology practice (trial) inspection. This is the 27th flight mission since China's manned space project was approved and implemented, and also the fourth manned flight mission after entering the space station stage. The success of the launch marks the successful completion of all 12 launch missions planned in the verification of key technologies and construction phase of the space station. (Liu Xinshe)
