What is the development history of shenzhou spaceship?

Shenzhou spaceship is a spacecraft developed by China, with completely independent intellectual property rights, reaching or superior to the international third-generation manned spacecraft technology. Shenzhou spaceship consists of three modules and one part, namely, the return module, the orbital module, the propulsion module and the additional part, and is composed of 13 subsystem. Compared with foreign third-generation spacecraft, shenzhou spaceship has the characteristics of high starting point and strong in-orbit staying ability.

Shenzhou series manned spacecraft was launched by the Long March II F rocket specially developed for it. The launch base is Jiuquan Satellite Launch Center, and the recovery site is Siziwangqi Space Landing Site in Wulanchabu City, Central Inner Mongolia. As of April 24, 2009, shenzhou spaceship and Tianzhou spacecraft are in the process of mass production of prototype products.

At 9: 22 on June 17, Beijing time, the Long March II F- 12 carrier rocket carrying the Shenzhou 12 manned spacecraft was ignited and launched at Jiuquan Satellite Launch Center. Since then, the Shenzhou-12 manned spacecraft has been successfully separated from the rocket, entered the predetermined orbit, and successfully sent three astronauts, Nie Haisheng, Liu Boming and Tang Hongbo, into space. The pilot was in good condition and the launch was a complete success.

Beijing time 202 1 June 7, 2008 15: 54, according to the news of China Manned Space Engineering Office, Shenzhou 12 manned spacecraft successfully completed orbit determination, successfully docked to the front port of Tianhe core cabin by autonomous rapid rendezvous and docking, and formed a three-cabin (ship) assembly together with the previously docked Tianzhou-2 cargo spacecraft. The whole rendezvous and docking process lasts about 6.5 minutes.

Shenzhou spaceship research planning:

According to the mission plan, the space station project is divided into three stages: key technology verification, construction and operation. In the key technology verification stage, six missions were arranged, including the first flight of Long March V-B carrier rocket, Tianhe-1 test core module, shenzhou spaceship and Tianzhou spacecraft. During the construction phase, six missions were arranged, including the space shuttle, Dreamliner, shenzhou spaceship and Tianzhou spacecraft.

China Space Station is named "Tiangong", which has distinct characteristics of China and the times. The overall scheme is optimized, and the space station body is formed through rendezvous and docking and transposition assembly. Its basic configuration includes Tianhe Core Module, Investigation Module No.1 and Meng Tian Module No.2, each of which is 20 tons in size.

During the on-orbit operation of the space station, the Shenzhou manned spacecraft provides crew transportation and the Tianzhou cargo spacecraft provides replenishment support. The design life of the space station is 65,438+00 years, which can be further extended by maintenance as required. The rated crew is 3, and it can reach 6 in a short time when the group rotates.

The space capsule is used for the unified management and control of the life of the space station and astronauts. It has three ports of call and two berths. The docking port is used for assembling the space station module, the dream module and the space station module to form a space station component; The docking interface is used for shenzhou spaceship, Tianzhou spacecraft and other aircrafts to visit the space station.
