On the early morning of October 30th, the launch of the Shenzhou-19 manned spacecraft was a complete success, and the vast space welcomed Chinese visitors born in the 1990s for the first time. At 4:27 am on the same day, the Long March 2F Y19 carrier rocket carrying the Shenzhou-19 manned spacecraft was ignited and launched from the Jiuquan Satellite Launch Center. About 10 minutes later, the Shenzhou-19 manned spacecraft successfully separated from the rocket and entered the predetermined orbit. The crew was in good condition and the launch was a complete success. The crew of astronauts carrying out the Shenzhou-19 manned flight mission consists of three astronauts: Cai Xuzhe, Song Lingdong, and Wang Haoze. Among them, astronaut Song Lingdong and astronaut Wang Haoze are the "post-90s" who have carried out their first flight mission. According to the China Manned Space Engineering Office, after entering orbit, the spacecraft will perform autonomous rapid rendezvous and docking with the space station assembly according to the predetermined procedure. The crew of Shenzhou-19 will rotate in orbit with the crew of Shenzhou-18. During their work and life on the space station, the crew of Shenzhou-19 astronauts will conduct multiple extravehicular activities, carry out experiments and applications in the fields of microgravity basic physics, space materials science, space life science, aerospace medicine, aerospace technology, etc., and complete various tasks such as the installation of space station debris protection devices, installation and recovery of extravehicular payloads and extravehicular platform equipment. This mission is the fourth manned flight mission of China's manned spaceflight project entering the stage of space station application and development. It is the 33rd launch mission since the project was approved and implemented, and also the 543rd flight of the Long March series carrier rocket. At present, the space station assembly has entered the docking orbit and is in good working condition, meeting the requirements for rendezvous and docking with the Shenzhou-19 manned spacecraft and the entry of astronauts.
