There are many experiments in the sky cabin, and space science is on a higher level…

​​​​On July 24, the high-profile Wentian experimental module was launched into space by the Long March 5B carrier rocket, and successfully rendezvoused with the space station Tianhe core module. It is understood that the Wentian experimental cabin carries 8 experimental cabinets, and its main tasks are life science and biotechnology research. What exactly are these scientific studies? Why work on the space station? Recently, a reporter from China Aerospace News visited relevant experts from the Chinese Academy of Sciences, who answered these questions.

Life Ecological Experiment Cabinet

Biomedicine welcomes opportunities

“The Wentian Experiment Module has planned and deployed more than 10 research themes in four fields, including space life science and biotechnology, microgravity fluid physics, space material science, and space application new technology experiments. Currently, more than 40 scientific projects have been established. The space station After completion, relevant scientific projects will be continuously demonstrated and implemented rollingly.” Lu Congmin, a researcher at the Space Application Center of the Chinese Academy of Sciences and deputy chief of the space application system for manned space engineering, introduced.

​In order to ensure the smooth development of the above-mentioned scientific tasks and the continuous production of scientific achievements, the space application system has deployed biological ecological experimental cabinets, biotechnology experimental cabinets, scientific glove boxes and low-temperature storage cabinets, and variable gravity scientific experimental cabinets in the Wentian experimental cabin. The experimental facility is equipped with shared support equipment for application tasks inside and outside the cabin, and jointly supports the implementation of the entire mission chain of scientific projects in orbit.

Among them, the life ecology experiment cabinet uses various types of biological individuals (such as plant seeds, seedlings, plants, and small animals) as experimental samples to carry out spatial growth experiments of animals and plants such as Arabidopsis thaliana, nematodes, fruit flies, and zebrafish. Attempts to reveal the influence of microgravity on the growth, development and metabolism of individual organisms, promote human understanding of the nature of life phenomena, study the effects and mechanisms of space radiation biology and submagnetic biology, and explore the establishment of an applied controlled life ecosystem. Provide scientific basis for astronaut on-orbit radiation damage assessment and protection.

Biotechnology Experiment Cabinet

​Biotechnology experiment cabinet takes tissue, cells and biochemical molecules and other different levels and types of biological samples as research objects, and carries out experiments such as cell tissue culture, space protein crystallization and analysis, protein and nucleic acid co-origin, space biomechanics, etc., to explore microgravity The law and mechanism of cell growth and differentiation in the environment may provide a theoretical basis for human health, reproduction and development; explore the impact of gravity on the origin and evolution of life; strive for high-efficiency protein/peptide drugs, nanocrystalline bone biotechnology, etc. The breakthrough discovery is expected to play an important role in guiding the research and application of tissue engineering and biomedicine.

Scientific Glove Boxes and Cryogenic Storage Cabinets

The scientific glove box provides clean and confined space and environmental control of temperature and humidity. It is equipped with a dexterous robotic arm and has the ability to operate at the cell level. The glove box provides safe and efficient support for astronauts to operate multidisciplinary experimental samples. The low-temperature storage device has three typical low-temperature storage temperature zones (minus 80 degrees Celsius, minus 20 degrees Celsius, and 4 degrees Celsius), which can meet the low-temperature storage requirements of different experimental samples.

The variable gravity scientific experiment cabinet provides 0.01~2g high-precision simulated gravity environment for scientific experiments. It adopts advanced wireless energy transmission and carrier communication technology to support the development of complex fluid physics under different gravity levels such as microgravity, simulated lunar gravity, and simulated Mars gravity. , the movement of particulate matter and other scientific research.

Variable Gravity Science Experiment Cabinet Opened

​Lv Congmin introduced that energy particle detectors and plasma in-situ imaging detectors are also deployed outside the Wentian experimental cabin to obtain data on environmental elements such as protons, electrons, neutrons, heavy ions and plasma in space, so as to protect the health of astronauts , to provide guarantee support for the safe operation of the space station, and can also be used for basic research on the space environment.

Special environment hardware is available

The completed China Space Station, as a national space laboratory, will support long-term, multi-field, large-scale space science and application research. Zhang Wei, a researcher at the Space Application Center of the Chinese Academy of Sciences and director of the Application Development Center, summarized the advantages of the Chinese space station from four aspects.

​First, the Chinese space station can provide long-term microgravity, radiation and other special research environments. ​Zhang Wei said that on the earth, life and matter are affected by gravity, and some essential laws will be covered up, and under the condition of microgravity, scientists hope to discover the essential laws of these substances. Not only that, but there are some physical effects in microgravity. “The first is that buoyant convection is greatly reduced; the second is that precipitation and stratification have basically disappeared; the third is that the pressure gradient is greatly reduced.” Zhang Wei said.

​Second, the Chinese space station has astronauts involved, which is convenient for experimental operations, experimental module replacement, and maintenance.

​Third, the Chinese space station can carry out round-trip transportation between the sky and the earth, and can realize the replacement of experimental modules and the return of experimental samples. After carrying out scientific experiments on life and materials in orbit, it is necessary to bring the samples back to the ground for further research.

​Fourth, at the specific orbital altitude of the Chinese space station, it is convenient to conduct astronomy, earth observation and space physics research. ​In this regard, Zhang Wei gave an example of astronomical observation: due to atmospheric absorption and interference, gamma rays, X-rays, ultraviolet rays, and infrared rays in the universe cannot be effectively observed on the ground. device into space.

It is worth mentioning that after the construction of the Chinese space station is completed, it will operate in orbit for more than 10 years. In addition to the advanced scientific experimental cabinets that have been developed, the space station’s external exposure experimental devices and the future launch of the Sky Survey Optical Module will also bring opportunities for more scientific experiments.

“Ask Tian” spreads its “big wings”, and the anti-vibration technology is really strong!

On the 6th August 2022 … After two months of trip or two months into a six months mission on the China Space Station after the docking of the Wentian Experimental Cabin Module…..  The Shenzhou 14 crew Takionaut has not finished unpacking the courier packages of the all new Wentian Experimental Cabin Module…  Today this week it’s been the very “busiest space Takionaut trio” continued to organize onboard supplies for 5.5 hours.

Above nine days ’s flexible solar panels have been unfolded twice, and finally revealed a beautiful overall picture. The Wentian experimental cabin under the “flying full wings” is even more majestic.

​Technical staff from the Fifth Academy of Aerospace reduce the impact of the vibration of the flexible solar panels on the rendezvous and docking tasks .


The “flexible” feature of the flexible solar panel determines that it is particularly easy to vibrate. If the control is not good, each “gentle vibration” may have a fatal impact on the space mission. To this end, on the basis of the semi-rigid solar panel control of the Fifth Academy of Aerospace Science and Technology Group, 502 has developed a method to suppress the vibration of flexible solar panels, and use the method of “four ounces” to make them “fly smoothly” in space.


Previously, most of my country’s spacecraft used semi-rigid solar panels. The core module of the space station launched in 2021 used flexible solar panels for the first time. Compared with the two, the semi-rigid solar panel has a narrow natural frequency range, and the algorithm is simple and easy to control, while the flexible solar panel is too soft and has a wide natural frequency range. The same control frequency on the spacecraft coincides with its natural frequency. , the windsurfing board will be excited and vibrated .


If this vibration is allowed to develop, it will affect the control accuracy and stability of the spacecraft , thereby affecting the load work and the rendezvous and docking. More importantly, if the control system is not specially designed, it may stimulate the control system to respond passively , resulting in a situation in which the more control, the more severe the vibration, the more severe the vibration, the more the control system needs to control, which in turn makes the system unstable and affects the space station. The track runs stably.


This is like two people carrying water with a pole, one can carry it, and the other can’t carry it. Those who can carry water can adjust the frequency and amplitude of the ups and downs of the body to make the pole on the shoulders vibrate very little, and control the water in the bucket to only have tiny ripples, and at the same time walk like a fly . People who can’t carry water will not control the pole by adjusting their body, which will cause the pole to shake up and down seriously, the bucket shakes violently, and the walking speed is also affected by the pole, which makes it faster and slower. There was less than half a bucket of water left.


The experts of the Aerospace Science and Technology Group use a similar method to suppress the vibration through the attitude adjustment of the spacecraft. The adjustment range may be small, but it is very useful.

As the so-called “knowing is not difficult, doing it is difficult”, the realization of the suppression of the vibration of the large flexible windsurfing board of the space station is inseparable from the research and development of the researchers for several years. They first identified the source of the vibration of the windsurfing board through theoretical analysis and experiments, and then found a way to control the source. Through fine mathematical simulation and a large number of physical simulations, they summarized and designed an effective algorithm for controlling the vibration of the solar windsurfing board. , the algorithm is the core technology to suppress the vibration of solar panels .


The basic process of its control is to first identify the vibration parameters of the flexible solar panel by means of camera observation, and then the computer determines the attitude adjustment that the spacecraft needs to make through the corresponding algorithm, and issues commands to the person responsible for adjusting the spacecraft attitude. Executive body. Although the developers have little knowledge of the technical details of suppressing the vibration of solar panels abroad, from the perspective of control effects, the control method of our independent innovation design is not only more suitable for the “physique” of Chinese spacecraft, but the main technical indicators are even better than those of foreign countries .


No matter how big or small, it must be considered, designed and verified. This is the characteristic of aerospace engineering. To build the Chinese’s own space station, the Chinese want to go deeper into the deep space and promote the building of a space powerhouse. Astronauts are making progress every day in the process of solving such large and small problems.
