On July 24th, the Long March 5 Yao Three Load Rockets equipped with the Wentian Experimental Cels ignited at the Wenchang Aerospace launcher in my country, and the China Space Station ushered in the first experimental cabin.

According to Lu Congmin, a researcher at the Chinese Academy of Sciences Space Application Center, the space application system asks the experimental compartment task of the sky is mainly based on life science and biotechnology research. More than ten research themes have been deployed in the four fields, and more than 40 scientific projects have been established.

It is understood that the Tianshi experimental cabin has deployed scientific experimental facilities such as life ecological experimental cabinets, biotechnology experimental cabinets, scientific glove boxes and low -temperature storage cabinets, and gravity science science experimental cabinets. The output of scientific achievements provides platform support.

Life Ecological Cabinet

What role will these experimental cabinets play each? According to reports, the life ecological experimental cabinet is based on a variety of biological individuals (such as plant seeds, seedlings, plants, and small animals) as experimental samples. Essence

Biotechnology experimental cabinet

This may mean that people will witness the growth of the lives of animals and plants in a special scene like space.

"This time I asked the sky cabin to bring some plant seeds. We hope to see them germinating, growing up from the state of the seed, and finally blooming, showing the full life cycle of high plants in space." Shi Zhang Tao introduced. At the same time, the experimental sample also includes aquatic creatures like zebrafish.

The life ecological experiments in space in space are conducive to revealing the impact of micro -gravity on the growth, development, and metabolism of biological individuals, promoting human understanding of the essence of life phenomena, studying the effects and mechanisms of spatial radiation biology and sub -magnetic biology, exploring and establishing applications The controlling life ecosystem provides a scientific basis for the evaluation and protection of astronauts in rail radiation damage.

In addition, the biotechnology experimental cabinet is targeted by 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. Effects on the origin and evolution of life.

Scientific glove boxes will provide clean and closed space and temperature and humidity environment control, and configure the dexterous robotic arm to have cell -level fine operation capabilities; glove boxes provide safe and efficient support for astronauts to operate multi -disciplinary experimental samples. The low-temperature storage device has three typical low-temperature temperature storage areas (-80 ° C, -20 ° C,+4 ° C), which can meet the low temperature storage requirements of different experimental samples.

Change gravity science experimental cabinet provides scientific experiments with 0.01G to 2G high -precision simulation of gravity environment. Adopt advanced wireless transmission energy and carrier communication technology to support the development of complex fluid physics at different levels Scientific research such as particle material movement.

In addition, "Ask the sky" also deployed energy particles detectors and plasma in situ imaging detectors outside the cabin to obtain environmental element data such as spatial proton, electronics, neutron, heavy ions and plasma, which is the health of astronauts , Space Station's safe operation provides support and support, and can be used for basic research on space environment.

Why do we have experiments at the space station? Zhang Wei, director of the Applied Development Center of the Chinese Academy of Sciences, introduced that first of all, it can provide a special research environment such as long -term micro -gravity and radiation.

Secondly, the manned space station has the participation of people, which is convenient for experimental operations, experimental module replacement, and maintenance. Third, the manned space station can carry out world -round transportation, which can achieve experimental module replacement and experimental sample return. Scientific experiments such as life and materials carried out on the rail are necessary to return the samples after the experiment and return to the ground for further research.

In addition, the height of the specific track of the space station is also convenient for astronomical, global observation and space physics research.
