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.
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 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.
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.
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.
