During the Shenzhou 14 mission, two experimental modules of the National Space Laboratory will be built with different tasks – Xinhua English.news.cn

Xinhua News Agency, Jiuquan, June 4 (Reporters Li Guoli and Zhang Ruijie) Lin Xiqiang, spokesman for China’s manned space project and deputy director of the China Manned Space Engineering Office, said at a press conference on the Shenzhou 14 manned mission on the 4th that Shenzhou During the No. 14 mission, the construction of the Tiangong space station with the Tianhe core module, Wentian experimental module and Mengtian experimental module as the basic configuration will be fully completed, and a national space laboratory will be built. Among them, the Wentian experimental cabin is mainly for space life science research, and the Mengtian experimental cabin is mainly for microgravity scientific research.

Lin Xiqiang said that as a national space laboratory, 25 scientific experimental cabinets can be deployed in the Chinese space station cabin. Each experimental cabinet is a small space laboratory, which can support the development of single- or multi-disciplinary space science experiments. International advanced level.

Lin Xiqiang said that the Wentian experimental cabin is mainly for space life science research. It is equipped with experimental cabinets such as life ecology, biotechnology and variable gravity science, which can support the growth, development and genetics of various types of plants, animals and microorganisms under space conditions. Research on response mechanisms such as , aging, etc., as well as experimental research on closed ecosystems, and through various online detection methods such as visible light, fluorescence, microscopic imaging, etc., support multi-level biological experimental research such as molecules, cells, tissues, and organs, and also support the development of different A comparative study of the growth mechanism of organisms under gravity conditions.

Lin Xiqiang introduced that the Mengtian experimental cabin is mainly for microgravity scientific research. Research on the fundamental laws of matter such as variable heat transfer, basic combustion process, and material solidification mechanism, as well as cutting-edge experimental research 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 consisting of hydrogen masers, rubidium clocks and optical clocks will be established to form the time frequency with the highest frequency stability and accuracy in space. system, and carry out cutting-edge scientific research such as gravitational redshift and fine structure constant measurement.

In addition, an out-of-vehicle exposure test device for materials and an out-of-vehicle general test device for components and assemblies are also arranged outside the cabin to carry out out-of-vehicle experimental projects. In the follow-up, the research facility of the Sky Survey Space Telescope that will fly in co-orbit with the space station will also be launched to carry out wide-area sky survey observations.

Relying on the above-mentioned in-vehicle scientific experiment cabinets, out-of-vehicle test devices and sky survey space telescopes, nearly 100 experimental research projects have been arranged during the construction stage of the space station. After the space station is put into normal operation, it will also carry out large-scale scientific research, which is expected to strongly promote dark matter and dark energy, the formation and evolution of galaxies, the laws of the nature of matter, the nature of life phenomena, and the laws of human response and change in space, as well as the sustainable development of the earth. Breakthroughs in major frontier scientific issues such as development provide profound scientific and technological accumulation for my country to carry out manned space exploration near the Earth and farther in the future.
