Wenchang, Hainan, 25 Jul (Xinhua) -- Title: Expert Interpretation: What experimental research will be carried out in the Q1 experimental module
Xinhua News Agency reporters Zhao Yeping, Zhang Ruijie and Wen Jinghua
With the smooth rendezvous and docking of the Wentian Experimental Module and the Tianhe Core Module, the Shenzhou 14 astronauts entered the Wentian Experimental Module in a group, and the construction of the Chinese space station took another key step. As the first space station science experiment module on the mainland, the Qtian Experimental Module can carry out experiments in space, which has attracted much attention. The reporter interviewed experts in related fields to interpret the upcoming experimental research of the Wentian Experimental Cabin.

The space station can provide a long-term microgravity, radiation and other special research environment, someone involved in the convenience of experimental operation, experimental module replacement and maintenance, space and space round-trip transportation can realize the replacement of experimental modules and the return of experimental samples. "Space science is the frontier field leading the development of our science and technology, and to explore how humans can survive outside the earth, or to study the origin of life, etc., we must carry out relevant experiments in outer space." Wang Ke, deputy chief engineer of space application systems and director of the Integration Technology Center of the Space Application Center of the Chinese Academy of Sciences, said.
Lu Congmin, deputy chief engineer of space application system for manned space engineering and researcher of the Space Application Center of the Chinese Academy of Sciences, introduced that the Wentian Experimental Module has planned and deployed more than 10 research themes in four fields, including space life science and biotechnology, microgravity fluid physics, space materials science, and space application new technology experiments, and has set up more than 40 scientific projects. With the launch of the QienTian experimental module, experimental research on the cultivation of higher plants under microgravity conditions will be carried out in orbit. After the completion of the space station, it will continue to demonstrate and implement relevant scientific projects on a rolling basis.
"In order to support the development of scientific experiments in related fields, a number of scientific experiment cabinets of about 1 meter wide, 1.8 meters high and 0.8 meters deep have been deployed in the Wentian experimental cabin, including life ecology experiment cabinets, biotechnology experiment cabinets, variable gravity scientific experiment cabinets, scientific glove boxes and cryogenic storage cabinets." Lu Congmin said.
Lu Congmin introduced that the life ecology experiment cabinet will carry out spatial growth experiments on arabidopsis, fruit flies, zebrafish and other animals and plants, revealing the impact of microgravity on the growth, development and metabolism of individual organisms, and promoting human understanding of the nature of life phenomena.

——The biotechnology experimental cabinet takes multi-level multi-category biological samples at different levels such as tissues, cells and biochemical molecules as the object, carries out experiments such as cell tissue culture, spatial protein crystallization and analysis, co-origin of proteins and nucleic acids, and spatial biomechanics, explores the laws and mechanisms of cell growth and differentiation in microgravity environment, provides a theoretical basis for human health and reproductive development, and explores the impact of gravity effect on the origin and evolution of life.
——Variable gravity science experiment cabinet provides 0.01G to 2G high-precision simulated gravity environment for scientific experiments, and adopts advanced wireless energy transmission and carrier communication technology to support scientific research such as microgravity, simulated lunar gravity, Martian gravity and other complex fluid physics under different gravity levels, and the motion of particulate matter.
——The scientific glove box provides clean and confined space and temperature and humidity environment control, and the configuration of the smart robot arm has the ability to operate fine operation at the cellular level, providing safe and efficient support for astronauts to operate multidisciplinary experimental samples; Cryogenic storage cabinets from -80°C to 4°C can meet the different temperature needs of different experimental samples.
——Energy particle detectors and plasma in situ imaging detectors are deployed outside the experimental module to obtain environmental element data such as space protons, electrons, neutrons, heavy ions and plasma, providing guarantee support for astronaut health and safe operation of the space station, and can be used for basic research on the space environment.

Although the scientific experiment cabinet is small, it is powerful. Zhang Lu, a researcher at the Space Application Center of the Chinese Academy of Sciences and deputy director of the Integration Technology Center, said: "The scientific experiment cabinet is equivalent to installing the scientific experiment system covering an area of tens of square meters into a cabinet of less than 2 cubic meters. ”
Wang Ke said that in addition to the development of advanced and reliable scientific experiment cabinets and other facilities in accordance with aerospace standards, each space project also needs to conduct in-depth scientific research in advance, and conduct high-level analysis of data and experimental samples afterwards, "Space science and applied research can not only help us understand the basic laws of physics and cosmology, but also improve the quality of life of human beings on the earth through biological, medical, materials science and other research, and can make some knowledge and technical reserves for human beings to go deep space in the future." ”
