Asked about the total length of the experimental compartment of 17.9 meters and the launch quality of 23 tons, consisting of working cabin, air gate and resource cabin. There are 1.2 tons of solar wing systems on both sides of the outer wall, nearly 1 ton of daily orientation device and truss components on the head, and nearly 2 tons of promoting fuel storage boxes in the stomach ...

Its successful launch is another important milestone in the construction of China Tiangong Space Station, marking the official opening of the China Tiangong Space Station's "construction in the orbit". This 20 -ton and 17.9 -meter spacecraft is currently the world's longest single manned manned spacecraft, which means that China has once again set a new World Aerospace record.

Research on Space Life Science

As an important part of the National Space Lab, asking the Tianyan experimental cabin can support the launch of a single -disciplinary or multi -disciplinary space science experiment. It is a "all -around" player integrating platform function and test load function.

Space Life Science is one of the important areas of spatial science research. On the one hand, it can use the special environment of space to study the mystery of life; on the other hand, it is also an important support basic scientific research that humans leave the earth and move towards space.

In this field, since the 1970s, foreign countries have carried out nearly half a century of research with the monopoly of space station technology.

NASA released 20 major scientific breakthroughs in the 20 -year operation of the International Space Station in 2020, of which 6 research is related to space life sciences, including the research of basic diseases such as Alzheimer, Parkinson, cancer, etc. As well as the research on the influence and response method of space life.

Today, we finally have the Tiantian experimental cabin -the space life science laboratory belonging to China, with the basic conditions for exploring the most cutting -edge of life sciences. China has become one of the only two countries in the world today with the basic conditions of space life science research.

In the working cabin of the Tiantian experimental cabin, 8 experimental cabinets were equipped with 4 scientific experimental cabinets, including life ecological experimental cabinets, biotechnology experimental cabinets. Utilizing the high vacuum and low gravity of the space station, and the cosmic radiation environment, people can participate in a large number of scientific experiments.

On the exposure platform outside the Quantian Experimental Class, 22 cabins were also equipped with 22 cabins. In the next ten years, the scientific experimental load equipped at the space station can accurately "send" the corresponding standard load interface position through the robotic arm. In addition, I asked the Tiangan experimental cabin to carry a set of 5 meters long robotic arm outside the air gate. The maximum radius of the activity range is 5 meters, which mainly bear the operation with higher accuracy requirements.

What experimental research will be launched

According to Lu Congmin, deputy chief president of the manned space engineering space application system and researcher of the Chinese Academy of Sciences Space Application Center, asked the Tiangtian Experimental Curring in 4 areas: More than 10 research themes have been deployed in the direction plan, 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 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. Wang Ke, deputy president of the Space Application System and Director of the Integrated Technology Center of the Chinese Academy of Sciences, 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 data on data afterwards. A high level of analysis with experimental samples. "Space science and application research can not only help us understand the laws and cosmic laws of the foundation. Human beings will move towards deep space in the future and make some knowledge and technical reserves. "

China Space Station opens the "double cabin" mode

As the first experimental cabin of the China Space Station, I asked Tian not only to explore the research scientific research of space, but also further enhanced the reliability of the space station and improved the living conditions of astronauts in the rail. Its unique scientific design, as well as the "unique artifact" carried, will also become a powerful support for deep space exploration.

According to reports, I asked the Tianjie Experimental Cels and the Core Card to back up. The key platform functions were consistent, which can fully cover the work requirements of the space station combination. Essence

"After the two -cabin docking is composed of a combination, the manned environment of the entire space station is uniformly managed and controlled by the sky and the core compartment. Once the sky and the core compartment occur seriously, ask the Tianjin experimental cabin to quickly take over and control the space station." Luo Yabin, chief designer chief designer of the Tiantian Experimental Card Environment Control System.

A more important detail is that asking the Tianjin experimental cabin is equipped with the largest flexible solar wings in China, and the double -wing can reach 55 meters after the development of both wings. The sun wings can track the sun with dual freedom, and the average daily power generation exceeds 430 degrees, which will provide sufficient energy for the operation of the space station.

At the same time, I asked the air gate of the Tiangan Experimental Class and the node compartment of the sky and the core compartment, and the out -of -service equipment support equipment of the spacerist system also backup each other to ensure the reliability and safety of the astronauts out of the cabin.

There are also 3 sleep areas and 1 sanitary zone in the cabin. The upgrade from the "one -bedroom" to the more spacious "two -bedroom room" can support the six astronauts of Shenzhou 14 and 15 to achieve the "Space Society" and the Rotary Rotation of the Rotal Rotation. Essence

In terms of living materials, I asked the Cabin to be equipped with rich passenger products, including space kitchen, charging equipment, and so on. The two sets of kitchen equipment brings great convenience to the life of the astronauts. On the basis of the sky and the core cabin, the Tianshi experimental cabin has also been optimized and upgraded in terms of sound absorption, noise reduction, and shock absorption.

According to the plan, after asking the docking of the Sky Experimental Class under the conditions of someone, the transgression operation will also be carried out to carry out the astronaut out of the cabin, and the "space lecture" activity that the children are most looking forward to and the space station.

In the Han Dynasty, Wang Yi mentioned "Ask the Heaven" for the first time in the preface of "Chu Ci Tian": "Ask the Heaven, and Qu Yuan's work. Heaven is full of lamenting and thinking about the rise and fall of history and thinking about the laws of the universe; and now people ask the sky, showing the spirit of climbing the vast universe and building a aerospace power.

Ask the sky to deploy, Mengtian is coming. According to reports, in accordance with the requirements of the vacuum heat test outline, the Mengtian Experimental Class has completed all the working conditions tests in turn, and during the test process, the harmful gas collection test and noise test in the sealing cabin were launched, laying a solid foundation for its factory to leave the factory. Essence

By the end of this year, as the Mengtian Experimental Curdine rise, the completion of the China Space Station will become the National Space Lab, bringing a deep -space dream of 1.4 billion people, and opening a new way of seeking.
