The Tianzhou-1 cargo spacecraft was successfully launched and docked with Tiangong No. 2, which opened the curtain of the construction of the China Space Station.
The construction of the space station in the third step of China’s manned spaceflight project will initially construct three sections, including one core compartment and two experimental cabins, each with a scale of more than 20 tons. The basic configuration is T-shaped, the core compartment is centered, and the experimental cabin I and the experimental cabin II are respectively connected to both sides. Subsequently, during the operation of the space station, at most, there will be one cargo spacecraft and two manned spacecraft. "The whole system will add up to more than 90 tons. After the space station is built in 2020, it will be put into normal operation immediately, carry out scientific research and space experiments, promote China's space science research into the world's advanced ranks, and contribute to the development and progress of human civilization.
Previously, on September 10, 2014, Yang Liwei said that the construction of the China Space Station will be completed around 2022. The space station that China will build around 2020 will become an important base for China's space science and new technology research experiments, and it has been in orbit for more than 10 years.
Wang Xiang, the chief commander of the China Space Station System, said in an interview with CCTV recently that China will build the first space station for Chinese people around 2022. The current development progress is relatively smooth, and it has entered the initial stage of development. The difficulties are being overcome.
Wang Xiang revealed that the goal of the China Space Station is to break through, master and develop the long-term manned technology in the near-Earth space, and the ability to build space facilities to ensure that people can live comfortably and effectively in space.
After the completion of the China Space Station, the total weight will be close to 100 tons. The main body consists of one core cabin and two experimental cabins. Manned spacecraft and cargo spacecraft will regularly transport personnel and materials, and carry out various experiments and work.
There will be at least four types of aircraft in the space, with a variety of work in space.
Wang Xiang said that the space station will be a solid foundation for China to move from the ground to space.
Chinese pride! China built its own space station around 2022
Ability to developThe space station is designed to be transported in a three-person state for a long period of time. The manned spacecraft implementation personnel are rotated every six months during the operation phase, and intermittent personnel access will be used in the initial stage. After the completion of the manned space station, it will become an important base for China's space science and new technology research experiments, and has been in orbit for more than 10 years.
The construction of the space station in the third step of China’s manned spaceflight project will initially construct three sections, including one core compartment and two experimental cabins, each with a scale of more than 20 tons. The basic configuration is T-shaped, the core compartment is centered, and the experimental cabin I and the experimental cabin II are respectively connected to both sides.
The front end of the core cabin is provided with two pairs of interfaces to receive the docking and docking of the manned spacecraft; the rear end is provided with a rearward facing interface for the cargo spacecraft to be recharged. An airlock cabin is provided on the station for the astronauts to exit the cabin, and a mechanical arm is provided for assisting docking, replenishment, exit and scientific experiments.
Subsequently, during the operation of the space station, at most, there will be one cargo spacecraft and two manned spacecraft. The entire system will add up to more than 90 tons.
The China Space Station has the ability to carry out. In the operational phase, new sections will be added to expand the scale and application capabilities according to the needs of scientific research.
One core cabin and two experimental cabins of the space station will be launched by the large launch vehicle Long March 5B; the cargo spacecraft and manned spacecraft will be launched by the medium-sized launch vehicle Long March 7.
The overall name of the China Manned Space Station and the five names of each cabin and cargo spacecraft are as follows: The manned space station is named "Tiangong", codenamed "TG"; the core compartment is named "Tianhe", codename "TH"; I named "Qiantian", codename "WT"; the experimental cabin II was named "Current Sky", codename "XT"; the cargo spacecraft was named "Tianzhou", codename "TZ".
China's space development is boomingIn the next few years, China will complete a number of spacecraft R&D missions. In 2017, China Academy of Aerospace Science and Technology Group 5 (referred to as "Aerospace Five Institute") will complete the development and launch mission of the "Chang'e V" aircraft to ensure the successful completion of the lunar sampling return mission. By then, China will become the third country in the world to independently master the return technology of lunar exploration. One year later, the development and launch of the "Chang'e IV" will achieve the world's first soft landing on the back of the moon.
According to Wang Zhongyang, spokesperson of the Fifth Academy of Aerospace, in the manned spaceflight project, the space laboratory of "Tiangong No. 2" and the manned spacecraft of "Shenzhou No. 11" will be launched this year; and next year, "Tianzhou No. 1" freight The spacecraft will take off and rendezvous and dock with the "Tiangong-2" space laboratory to verify the space station propellant on-orbit replenishment technology; around 2018, the core capsule of the "Tianhe No. 1" space station will be launched, which is built by China's space station. An important starting point.
By 2022, the construction of the space station will be completed. By then, it will become the third space station in the world after the International Space Station (overtime service) and the Mir (decommissioned). It is expected that by 2024, with the retirement of the International Space Station, China will become the only country that has a space station in space.
Wang Zhongyang said that during the "13th Five-Year Plan" period, the Fifth Academy of Aerospace will also develop five satellites, including "High Score No. 6" and "High Score No. 7", to complete the construction of a high-resolution Earth observation system. In addition, during the "Thirteenth Five-Year Plan" period, the construction of the national civil space infrastructure system will be basically completed, and 40 remote sensing satellites and 25 or so communication broadcasting satellites will be stably operated in orbit, providing spatial information services to support social and economic development.
In addition, around 2022, the Space Academy will complete and launch the "Current Sky" optical cabin, which functions similarly to the US Hubble Space Telescope.
