Expert interpretation Ask Sky Curring Launch: This battle is very critical

Jimu Journalist Zeng Lingzheng

At 14:22 on July 24th, the Long March 5 Yao Three Launar Rockets equipped with the Experimental Class of the Tiantian Experiment launched the launch of the "Ask Sky" in Wenchang Aerospace launched in Wenchang, Hainan. China Space Station is about to usher in the first experimental cabin, and Chinese astronauts will also visit the space station for the first time in the rail.

Jiao Weixin, a professor at the School of Earth and Space Sciences at Peking University, analyzed to Jimu Journalists that the launch and docking of the sky cabin on the one hand were the verification of existing construction technology, and on the other hand, it also laid the foundation for the docking of the subsequent Dream Counter. In the future, the experiments conducted in the cabin will also explore the growth mechanism of creatures and how the human structure under different gravity conditions.

Experimental compartment and core compartment docking technology will be verified by security

At 14:22 on July 24th, the Long March 5 Yao Three of the Long March 5 Yao Three Lairer was carried on the launching site of Wenchang Aerospace, and the launch was successful.

This is the 24th flight mission since the implementation of the Chinese manned space project. The launch of the questioning compartment of the launch is the second cabin section of the China Space Station and the first scientific experimental cabin. According to the China Manned Aerospace Engineering Office, I asked the Tiangan Experimental Curring Card consisting of working cabins, air gates and resource cabins. The take -off weight is about 23 tons. Can be used as a backup of the sky and the core cabin to manage the space station.

In the follow -up, the questioning compartment of the sky will meet and dock in accordance with the predetermined procedure with the space station combination. The Shenzhou No. 14 Aerospace Worker's multiplier will enter the Qi Tian experimental cabin to carry out the work.

Jiao Weixin, a professor at the School of Earth and Space Sciences at Peking University, introduced to Jimu Journalists that China Space Station is also a future space science laboratory. It mainly has three layers of structures, namely one core compartment and two experimental cabins. The discipline experiments are mainly conducted in the two experimental cabins. One of the experimental compartment is the questioning of the cabin launched today.

Jiao Weixin pointed out that after the launch is successful, you still need to pay attention to the docking of the skycase and the core cabin. This docking will verify the feasibility of the predetermined scheme, and also lay the foundation for the launch and docking of the future Dream Class.

"According to the predetermined scheme, the docking of the experimental compartment and the core compartment must first be connected at an axial angle. After the docking, use the" Conversion Robot Arm "technology to turn the sky compartment 90 degrees and turn to the side to connect with the core compartment. Although before, I have trained the transgression robotic arm technology, but this time the docking is a real knife and real gun, and the quality of the sky cabin is 22 tons. When there is a little collision when the docking, it may cause harm to the space station. It shows that the most critical problem in the construction stage is solved, and there are no tricky technical problems in the future, so this battle is very critical. "Jiao Weixin said.

Mainly conduct space biology research

Lin Xiqiang, a spokesman for Chinese manned aerospace engineering and deputy director of the China Manned Aerospace Engineering Office, introduced that as a national space laboratory, 25 scientific experimental cabinets can be deployed in the Chinese space station cabin. Each experimental cabinet is a small space experiment The room can support space scientific experiments with cross -disciplinary or multi -disciplinary interdisciplinary interdisciplinary, and reaches the international advanced level as a whole.

Among them, I asked the Tiangan experimental compartment mainly for spatial life science research, and configured experimental cabinets such as life ecology, biotechnology, and gravity science. Research on aging and other response mechanisms, as well as experimental research on a closed ecosystem, and through various online detection methods such as visible light, fluorescence, and microcomposter, support multi -level biological experimental research on molecules, cells, tissues, organs, and can also provide 0.01g -2G's gravity simulation, support the comparative research of organism growth mechanism under different gravity conditions.

Jiao Weixin introduced that spatial life science research includes spatial biology, space physiology, space medicine and space biological engineering.

"Spatial physiology study human structure and function of human body under various conditions of space. For example, micro -gravity will affect the skeletal structure of astronauts, and it will also affect the astronaut's cardiovascular system. The weak muscles and bones cannot maintain the same as on the earth as on the earth. Blood flowing speed. What measures do I need to take to reduce the environmental effect of micro -gravity? Space medicine is to try to solve the medical problems encountered by astronauts in performing space mission, such as radiation and osteoporosis after returning to the earth. "Jiao Jiao, etc. The renovation further explained: "Taking the United States as an example, for the research on space medicine and space physiology, the US Aerospace Administration also specifically set up the 'Human Research Program'."
