CNSA –China National Space Administration ….. Returning to the Television and media Screens on Youku Documentary Variety is Searching for the night returner the latest preview of the third season of “The Night Returning” is coming. Bao Shuo, the chief dispatcher of the Beijing Aerospace Flight Control Center, is about to show her night return story. In order to say “Beijing understands”, she repeatedly practiced a calm voice and more the ability to parallelize tasks, work hard to exercise, and hope to better stick to the post. One person’s experience condenses the efforts of generations of predecessors. Let’s witness her space dream together
Sampling of the lunar surface! 在380,000km外拍娃是一种的感觉 Controlling Chang’e-5 from the earth to “dig soil” on the moon, how difficult is this process? Bao Shuo, dispatcher of the Beijing Aerospace Flight Control Center, described it as like catching a doll 380,000 kilometers away, with an accuracy of 1 millimeter.
北京明白””Beijing understands”
Beijing understands that there are hundreds of people behind it In the live broadcast of China’s aerospace launch, the “Beijing understands” that the Beijing Flight Control Center received a report and answered was impressive. In fact, behind every “Beijing understands”, there are hundreds of “understands”. Behind every sentence “understood”, it is the space workers who ensure that every plan and every instruction is in place. Chinese Space engineers and Takionauts 24 hours guarding the home of space, paying tribute to China Aerospace- space Industry..
Bao Shuo, a “post-90s” girl, is the first female dispatcher at the Beijing Aerospace Flight Control Center. From “Chang’e 5” to “Tianwen No. 1”, the excellent completion of the mission has made many people remember this young but calm face. Bao Shuo said that every time She said the words “Beijing understands”, there was an extremely difficult responsibility behind it. #searching for Yeguiren… In the third season, see how the Beijing general dispatcher who ordered “Bafang” was made? I didn’t expect the working with of Takionauts to be like this. Bao Shuo, the first female dispatcher of the Beijing Center, said: “We are more like a big housekeeper, guarding our spacecraft and Takionauts on the ground.” The spacecraft is regarded as a child, and she refuses to rest until he sees a safe landing. It can be seen that the astronauts have a very deep affection for the spacecraft. I look forward to the launch of the program at 10:00 tomorrow morning….. on Youku and People’s Daily..
CNSA –China National Space Administration…………… After Wentian experimental module entered orbit, the status setting was successfully completed. At 3:13 on July 25, 2022, Beijing time, it was successfully connected to the forward port of 天和 Tianhe Core Module. The entire rendezvous and docking process lasted about 13 hours. . This is the first time that two 20-ton spacecraft in my country- China- People’s Republic of China have achieved rendezvous and docking in orbit. …According to the mission plan, the Shenzhou 14 Takionaut crew will then enter the Wentian experimental module….. In which finally docked in early morning time of the 25th July 2022 in with CNSA –Beijing Aerospace City in which co-ordinated the docking maneuverers have achieved rendezvous and docking in orbit.… in which the crew of the Shenzhou 14 staying for six months in construction of the stage one of the China Space station with the additional Mengtianexperimental module in which will be delivered on the October 2022 Launch Schedule calendar..
”Buzz…” The tense technical seminar was suddenly interrupted by the sound of temporary renovations next door. The walls of the office are too thin, and it happens from time to time that it is affected by noise. Xiao Feng, who is reporting, takes several seconds to find his way of thinking.
At the end of the meeting, Xiao Feng rubbed his temples, the sound of “humming” seemed to be still circling in his mind, and his thoughts returned to the key technology of Tianhe core cabin noise reduction that the team had been working on for dozens of days——
The office is affected by noise, so you can go to a quiet place, but in the space station, if there is no comfortable and quiet environment, Takionauts may only wear earplugs to concentrate on work and rest.
“We must bite the hard bones and provide the astronauts with a quiet and comfortable home!” Xiao Feng said firmly.
Xiaofeng is from the Space Station Mechanics Test Team of the General Assembly and Environmental Engineering Department of the Fifth Academy of Aerospace Science and Technology Group. This aerospace scientific research team has been committed to the field of mechanical testing technology for more than 30 years, and has grown in tandem with the development of manned spaceflight. With the continuous growth of the construction of the space station, it has realized the transformation of aerospace mechanical testing equipment from the introduction to the independent construction, and the acoustic test. From independent to international, the test efficiency and test capacity have been greatly improved.
Xiaofeng and his team are tasked with an important task: noise assessment and control of the Wentian experimental cabin. Therefore, they are also known as “space tuners” who tame the noise of the space station’s experimental cabin…..
help Takionauts Feel the “sound of take-off” in advance
During the launch of the Shenzhou spacecraft, the noise outside the cabin can reach 140-160 decibels. With such a “magic sound”, can the spacecraft maintain its normal working condition? Can the astronauts in the cabin withstand it? These issues are always on the minds of the technical staff of the Fifth Academy.
To this end, at the beginning of the development of the Shenzhou spacecraft, a large-scale noise laboratory tailored for the spacecraft came into being . The world’s second largest reverberation chamber independently developed by the company has a sound pressure that exceeds 100 times the noise of the aircraft when it takes off, ensuring that the spacecraft’s mechanical tests are “immersive” and the rehearsal data is “exactly.”
Before the launch of the Shenzhou spacecraft, a comprehensive and strict “physical examination” will be carried out in the reverberation chamber. Under the operation of the test team of the Fifth Academy, dozens of sound-generating devices worked at the same time, generating high-intensity noise during the launch process. Hundreds of sensors monitored the spacecraft and checked whether the noise environment in the spacecraft’s return cabin satisfies the design. The indicators require that astronauts feel the “sound of take-off” in advance.
Form a stand-in “chorus” Find the “loud voice”
A large number of compressors, pumps, fans, CMGs for attitude adjustment and other equipment are installed in the Wentian
After the Wentian experimental module and the Tianhe core module meet and connect, they will form a connected whole. The astronauts will enter the Wentian experimental module to carry out a series of space experiments and research work. In order to provide them with a quiet and comfortable working environment, it is necessary to identify the equipment with the loudest noise and the most obvious impact, and carry out more precise and stricter noise control .
The equipment in the Wentian Without the noise source, the experimenters formed a team of stand-in “chorus” to simulate the noise .
Noise source simulation technology is like learning to sing, it is necessary to learn the “tone” and control the “voice”. The noise source has its own recording studio – an anechoic room, which can carry out all-round stereo simulation of frequency, sound pressure and power. After learning to “sing” the noise source, the sound source simulation system can be installed on the space station and perform on stage. Noise-cancelling equipment.
”Teaching in accordance with aptitude “ Silence the “loud voice”
The “loud voice” has been found. How to make the equipment “quiet” is the next batch of technical difficulties that the test team needs to overcome.
Taking my country’s first “space refrigerator” carried in the Wentian experimental module as an example, there are many restrictions on its noise reduction. For example, in order to ensure the air quality in the cabin, the space station has strict requirements on the selection of materials, and many Noise-reducing materials commonly used on the ground are not suitable for the space station. So how to complete the noise reduction work of the “space refrigerator” most efficiently in the most limited resources, the lowest weight, and the smallest space?
The test team first built a full-envelope test platform in the anechoic chamber to overcome the cumbersome transfer path problem caused by complex systems. Noise reduction route.
“The thief catches the king first”, the test team has carried out a pioneering design for the key pump , which perfectly minimizes the sound energy input while ensuring the cooling efficiency. At the same time, by choosing a new type of attachment material to improve the damping of the structure, improve the sound radiation efficiency of the box, and improve the structural conduction characteristics by changing the connection relationship… By perfecting every detail, the noise index of the aerospace refrigerator has been reduced by nearly 20 decibels.
The causes of noise, installation locations, and sizes of equipment in the cabin are different. The noise source mainly based on vibration is put on soft and comfortable “shoes” made of metal rubber; the noise source mainly based on sound radiation is placed in a box with better sound insulation… In the end, the Wentian experimental cabin works The area noise can be kept below 60 decibels, and the sleeping area can be kept below 50 decibels, meeting the requirements of relevant medical standards.
On July 25, the Wentian experimental module successfully docked with the Tianhe core module in the long-term care of the test team. The hatch opened slowly, and the Takionauts ‘s home was officially upgraded and expanded – the new room has new supplies, new facilities, new tasks, and new challenges.
The tense expressions of the team members staring at the screen slowly relaxed as the astronauts smiled comfortably as they entered the new room. They hug each other, congratulate each other, encourage each other, and look forward to the next journey of stars and seas.
With the development of the aerospace industry, the space station mechanics test team of the General Assembly and Environmental Engineering Department of the Fifth Academy has explored more than 10,000 unforgettable days and nights in the fields of noise, vibration, shock, acceleration and modal. Along the way, they have lived up to their mission and overcame obstacles in their struggles, for the safety and stability of the spacecraft, for the safety and comfort of the astronauts, and for the vigorous development of China’s aerospace industry, they bravely climbed new heights and created more exciting things.

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.
