On October 31, 2022, the Mengtian experimental module was launched. After entering the orbit, the Mengtian experimental module will complete docking and transposition with the core module, and China's space station will change from "two modules" to "three modules", forming the basic configuration of the "T" shape. With the in-orbit operation of the Mengtian experimental module, China's space laboratory will be really built, and the construction of China's space station will also enter the final stage.

(picture from our space official) according to China's space plan, after the Mengtian experimental module and the space station form a "T" shape, the Chinese space station will also usher in the Tianzhou V cargo spacecraft and Shenzhou 15 manned spacecraft. At this time, Shenzhou 14 has not yet returned, and the space station will form a six-module configuration for the first time, with six astronauts in orbit for the first time, setting a new Chinese space record.

With the completion of the on-orbit construction of the space station, the Chinese space station will enter the stage of application and development for more than 10 years. Hao Chun, director of the China manned Space Engineering Office, revealed in an interview with the media that in the stage of application and development of the space station, it is planned to launch two manned spacecraft and two cargo spacecraft every year. The astronauts will stay in orbit for a long time, carry out space science experiments and technical experiments, and take care of and maintain the space station at the same time.

What is the Mengtian experimental module for? China Tiangong Space Station is composed of Tianhe-1 core module, Tiantian experimental module Ⅰ and Mengtian experimental module Ⅱ. Tianzhou spacecraft and Shenzhou spacecraft undertake the task of material supply and personnel rotation of the space station respectively. In addition, there is an optical module of the Patrol that flies in orbit with the space station.

Mengtian and Mengtian are two experimental modules of the space station, which undertake different experimental tasks. According to officials, the experimental module is 17.9 meters long and has a launch mass of 23 tons. It consists of three parts: the working module, the airlock module and the resource module. The main task of the experimental module is to carry out life science and biotechnology research.

The experimental module was successfully launched on July 24, 2022, and completed docking with the core module 13 hours later, forming a "one" configuration with the core module. Two months after the orbit, in order to welcome the arrival of the Mengtian experimental module, the experimental module completed its transposition on September 30 and was transformed into an "L" configuration in combination with the core module. When the Mengtian experimental module is launched, it will be combined with the space station to form the basic configuration of the third module "T".

As the second experimental module of the space station, the Mengtian experimental module has an axial length of 17.9 meters, a maximum diameter of 4.2 meters, and a launch mass of about 23 tons, which is composed of four parts: the working module, the cargo airlock module, the load module and the resource module.

Com) unlike the Mengtian experimental module, the Mengtian experimental module is mainly for microgravity scientific research, and is equipped with experimental cabinets with multi-disciplinary directions, such as fluid physics, material science, combustion science, basic physics and aerospace technology experiments. It supports the study of the nature of matter such as multiphase flow and phase transition heat transfer, basic combustion process, solidification mechanism of materials under gravity masking, as well as cutting-edge experimental studies such as ultra-cold atomic physics.

At the same time, on the basis of the Tiangong-2 space cold atomic clock, the world's first set of space cold atomic clocks composed of hydrogen clocks, rubidium clocks and light clocks will be established to form a time-frequency system with the highest frequency stability and accuracy in space. carry out cutting-edge scientific research such as gravitational redshift, fine structure constant measurement and so on.

The main task of the Mengtian experimental module is to complete the rendezvous and docking with the Tianhe core module, segment transposition and parking in orbit, so as to provide guarantee conditions for astronauts to work in the sealed cabin and ensure the safety of astronauts.

With the successful launch of the Mengtian experimental module, the Chinese space station will eventually build a national space laboratory. According to Lin Xiqiang, spokesman for China's manned space program, as a national space laboratory, 25 scientific experimental cabinets can be deployed in the module of China's space station, each of which is a small space laboratory. it can support the development of single-disciplinary or interdisciplinary space science experiments, reaching the international advanced level as a whole.

What else can the space station do after the perfect end? According to the plan, after six missions in 2022, the Chinese space station will be completed in orbit. After the end, what else can the Chinese space station do? What other plans will be made for China's manned space program?

Hao Chun, director of the China manned Space Engineering Office, said at a news conference that after the Chinese space station is fully completed, the manned space project will enter the stage of application and development for more than a decade. The initial plan is to launch two manned spacecraft and two cargo spacecraft every year. Astronauts should stay in the space station for a long time, carry out space science experiments and technical experiments, and take care of and maintain the space station.

"at the same time, a new generation of manned carrier rockets and a new generation of manned spacecraft will be developed. the re-entry module of a new generation of manned carrier rockets and a new generation of manned spacecraft can be reused. we will also carry out larger-scale space research experiments and new technology experiments." "in addition, especially in 2023, we plan to launch China's first large space survey telescope to carry out wide-area sky survey," Hao Chun said. cutting-edge scientific research will be carried out in the formation and evolution of the structure of the universe, dark matter and dark energy, exoplanets and solar system celestial bodies, and a number of major innovations are expected to be achieved. "

Space expert Huang Zhicheng once told NetEase Science and Technology "chasing Dreams and Starry Sky" that once the Tiangong space station is completed, it means that China's manned space project will enter the space station era. China has also become the third country to build a space station on its own.
