With the successful meeting of the Tianshi experimental cabin and the sky and the core cabin, the Shenzhou 14th astronauts multiplied by group entered the questioning compartment of the Qi Tian, ​​and the construction of the China Space Station has taken another key step. Asked about what experiments can be carried out in space as the first space station scientific experimental compartment in my country, it has attracted much attention. The reporter interviewed experts in related fields to interpret the experimental research on the experimental compartment of the day.

The space station can provide a special research environment such as long -term micro -gravity and radiation. Some people participate in the convenience of experimental operations, experimental module replacement, and maintenance. The round -trip transportation of the world can achieve experimental module replacement and the return of experimental samples. "Space science is the cutting -edge area of ​​our scientific and technological development. To explore how humans survive outside or study the origin of life, we must conduct relevant experiments in outer space." Director Wang Ke said.

Lu Congmin, deputy chief chief of manned space engineering space application system and researcher of the Space Application Center of the Chinese Academy of Sciences, introduced the four areas of the experimental compartment in 4 areas such as space life science and biotechnology, micro -gravity physics, spatial materials science, space application new technology test The plan has been deployed more than 10 research themes, and more than 40 scientific projects have been established. With the launch of the experimental compartment of the sky, experimental research on the cultivation of higher plants under micro -gravity conditions will be carried out one after another. After the completion of the space station, it will continue to demonstrate and roll up related scientific projects.

"In order to support the development of scientific experiments in related fields, I asked a scientific experimental cabinet of about 1 meter, 1.8 meters high, and 0.8 meters deep in the experimental compartment, including life ecological experimental cabinets, biotechnology experimental cabinets, and gravity science experiments Cabinet, scientific glove boxes and low -temperature storage cabinets, "Lu Congmin said.

Lu Congmin introduced that the life ecological experimental cabinet will carry out the space growth experiment of the animals and plants such as the southern mustard, fruit flies, and zebrafish, reveal the impact of micro -gravity on the growth, development, and metabolism of biological individuals, and promote human understanding of the essence of life phenomena.

——The biotechnology experimental cabinet is targeted at different levels of biological samples such as tissue, cells and biochemical molecules to carry out experiments such as cell tissue culture, spatial protein crystals and analysis, protein and nucleic acid co -origin and spatial biomechanics. Laws and mechanisms of lower cell growth and differentiation provide theoretical foundation for human health and reproductive development, and explore the impact of gravity effects on the origin and evolution of life.

——Shamnity Science Experimental Cabinet provides scientific experiments with 0.01G to 2G high -precision simulation of a gravity environment. Adopting advanced wireless transmission energy and carrier communication technology to support the complexity of different levels of gravity, simulation of lunar gravity, Mars gravity and other complex levels Scientific research such as fluid physics, particle material movement.

——The scientific glove box provides clean and closed space and temperature and humidity environment control. Configuring a dexterous robotic arm has cell-level fine operation capabilities to provide safe and efficient support for astronauts to operate multi-disciplinary experimental samples; low temperature storage from -80 ° C to 4 ° C The cabinet can meet the different temperature needs of different experimental samples.

——The deployment of energy particle detectors and plasma in situ imaging detectors outside the experimental cabin to obtain environmental element data such as spatial proton, electronics, neutron, heavy ions, and plasma, which provides guarantee for the health operation of astronauts and space stations. Support and can be used for basic research on space environment.

Although the scientific experimental cabinet is small, it is powerful. Zhang Lu, a researcher at the Chinese Academy of Sciences Space Application Center and deputy director of the Integrated Technology Center, said: "The scientific experimental cabinet is equivalent to installing the scientific experiment system that occupied dozens of square meters into a cabinet that is less than 2 cubic meters."

Wang Ke said that in addition to the development of advanced and reliable scientific experimental cabinets and other facilities in accordance with the 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. It can help us understand the laws of physics and cosmic, and at the same time improve the quality of human life on the earth through research through biology, medicine, materials, etc., and can make some knowledge and technical reserves for human beings to go deep space in the future.
