At 9:22 on June 17, Beijing time, the Long March 2 F Yao 12 carrier rocket lifted the Shenzhou 12 manned spacecraft to tow the red tail flame into the air. "The Strongest Double Twelve" teamed up to send three astronauts Nie Haisheng, Liu Boming, and Tang Hongbo into space. This is the first manned mission of the Chinese Space Station during the orbital construction phase, and the space station construction mission has once again taken a big step forward.

     The Shenzhou 12 manned spacecraft is the first manned spacecraft in the mission phase of the Chinese space station. It is also the manned spacecraft with the highest standards and the most stringent requirements for various indicators developed by China so far.

     According to the scheduled plan, the Shenzhou XII spacecraft will adopt an autonomous rapid rendezvous and docking mode to form a combination with the space station’s sky and core module forward docking interface. The three astronauts will return to the ground after staying in space for about 90 days. 

    In fact, the leap-forward development of the Shenzhou manned spacecraft was not achieved in one step. Since the establishment of the "three-step" development strategy of China's manned space project on September 21, 1992, the Shenzhou manned spacecraft has passed verifications time after time. Yifa's success continues to accumulate experience and technology.

    Shenzhou 1 to Shenzhou 4 achieved unmanned verification of the space-to-earth round trip, Shenzhou 5 carried astronaut Yang Liwei to realize manned round-trips, Shenzhou 6 realized multi-person and multi-day round-trip activities, and Shenzhou 7 realized astronaut out-of-cabin activities. , Shenzhou 8 to Shenzhou 10 broke through unmanned rendezvous and docking and manned rendezvous and docking, and Shenzhou 11 realized the mid-term residency of astronauts.

    Today, the successful launch of the Shenzhou XII spacecraft has laid a good start for the space station construction mission for manned spacecraft to and from the world. At this point, Shenzhou 12 has gathered all the "skill points" needed for all missions and all modes to go back and forth between heaven and earth.
