"This time, Chinese astronauts may plant a few stubble rice on space"
Author:Changjiang Daily Time:2022.07.26
Seeing on the big screen of the Beijing Aerospace Flight Control Center, Chen Dong, Liu Yang, and Cai Xuzhe were busy work. There may be careful audiences that their work environment is not the same as before. Their place is now the question compartment that has just been successfully connected with Tianhe's core compartment this morning. At this moment, wireless launch devices are installing.
From the successful launch of yesterday afternoon to the perfect docking today, the arrival of the Tiangan experimental cabin not only provided the spacemen with greater tracking and living space, but also marked the construction of the Chinese Space Station and the National Space Laboratory. Take a key step before.
At around 3 am on July 25, the Chinese Space Station who took the Long March 5B Rockets to take off the day after the track of the Tiangtian Experiment Curm after 13 hours, caught up with the Tianhe core compartment combination.
In the past, Chinese astronauts entered space as "cabins and others", and astronauts waited for astronauts to visit. Asked about the docking of the Cabling this time, it was the first time that Chinese astronauts have experienced "people waiting for people" in space, and they are still waiting for the quality of more than 20 tons. The docking is unprecedented.
Another more tense factor comes from the sun wings of the Cabin Cabin. Like the core cabin, the sun wing of the sky cabin is also made of flexible materials developed by our country. In order to ensure that there is enough energy supply after the space station is completed, the solar wing of the sky cabin is up to 55 meters, which is equivalent to the height of 20 floors.
Zhang Jun, deputy director of the GNC sub -system of the Five Hospital System of Aerospace Science and Technology Group: It will shake, and the docking accuracy and stability indicators of the docking docking are relatively high. Once all are expanded, the vibration is very large, and the indicators will be destroyed. Therefore, when I was track, for the first time, it was in a state of semi -launched to form a second expansion after forming a combination.
Seven hours after the success of "Ask the sky" and "Tianhe", the three astronauts entered the experimental cabin.
Li Yan, director of the technical experimental division system of the Five Hospital System of Aerospace Science and Technology Group: Asked about 18 meters from the Cabin Cryle The open room becomes two big open rooms.
From the perspective of the appearance, I asked the Tianjie experimental cabin is obviously different from the sky and the core compartment. Asked about three parts: working cabin, air gate and resource cabin. The main activity space of the astronauts is the working cabin of the cylindrical structure and the air gate next to it. The largest working cabin in space is where the names are working, but they are actually their second rest area in space.
Li Yan, chief designer of the technical experimental division system of the Fifth Hospital System of Aerospace Science and Technology Group: There are three sleep areas, but it is just vertical, but there is no horizontal concept in the orbit, so the effect is the same for the use of astronauts on track. of. There is also a sanitary area that is backup with the core cabin.
What is the effect of the air gate? Prior to this, when the astronauts of Shenzhou 12 and Shenzhou 13, when the spacemen from the two flight rides were out of the cabin, they all entered and exited from the node compartment of the sky and the core compartment, but this is not the main in the future of the space staff to enter and exit the space station in the space station. aisle. After the launch of the sky cabin, this air gate will assume this function.
Wang Wei, director of the overall research office of the Fifth Hospital Space Station of Aerospace Science and Technology Group: Because the node compartment is the hub of the space station, if there is a failure, there is no way to seal it, and the connectivity of the entire space station will be destroyed. Therefore, at the beginning, on the test cabin, the dedicated outlet and mouth were designed. Once you "ask the sky", the main outlet is mainly used to make the cabin port from this dedicated outlet mouth. It can play a role of backup.
Making different functions "backup" is the most important means of ensuring the safety and reliability of the aerospace engineering guarantee system. In addition to providing more support and backup of the lives and work of the astronauts, it is more important that it is the same as the sky and the core compartment. It has complete functions. If the core cabin is the strongest brain of China Space Station, asking the Tiangan Experimental Cels is the "backup brain" that can always take over.
Wang Wei, director of the overall research office of the Fifth Hospital Space Station of Aerospace Science and Technology Group: The developers are more worried about the stage of a single -cabin flight of the core class because it is not backup. This cabin is now very good. Core compartment backup effect. So even if there are some wind blowing grass, we will have a bottom heart, and the whole reliability will be higher.
Scientific experiments are the main purpose of asking the sky -high experimental cabin. What research does the experimental cabin do? At the Chinese Academy of Sciences Space Application Engineering and Technology Center, the reporter saw the design of various experiments in the National Space Lab.
Zhang Wei, director of the application development center of the Chinese Academy of Sciences Space Application Engineering and Technology Center: Ask the sky cabin is actually the first experimental cabin, including life ecology, biotechnology, mixed gravity, and glove boxes. After the launch of the cabin is successful, a large number of scientific experiments will be supported.
This time, the four experimental cabinets in the Tiangtian experimental cabin mainly carried out research on space life science. In the life ecological experimental cabinet, the two plants will be the earliest object to start experiments.
Zhang Tao, head of the Life Science Instrument Team of the Chinese Academy of Sciences Shanghai Technology Institute: The goal of science is to grow from seeds to seedlings under the conditions of micro -gravity, to grow into plants, and finally flowering seeds. There are radiation, there are no these factors on the ground, the growth cycle, results, and even flowering cycles, the condition of the seeds will be different. From the perspective of the process, it is very valuable for scientific research. The lift rice is a low -straw rice variety "Xiaowei" specially cultivated by the Chinese Academy of Agricultural Sciences. Compared with the traditional rice, its figure is more suitable for planting in space stations.
Before the academician of the Chinese Academy of Sciences and the director of the Chinese Academy of Agricultural Sciences: It was short, about 20 cm, up to 30 cm. The earliest was for theoretical research, so that everyone could grow anywhere. We long for it to succeed, starting the germination after space, and the life cycle is gradually realized.
If the experimental results are smooth, this time, astronauts on the space station on duty may have to take a little bit of farm work from time to time and plant a few stubble rice in space.
Cang Huaixing, a researcher at the Space Application Engineering and Technology Center of the Chinese Academy of Sciences: After thoroughly studying plants in the laws of space, it can further cultivate grain crops suitable for growing and growing in space. Whether it is the moon or even immigrating to Mars in the future, it is very meaningful to go to Mars to plant food crops in the future.
In the Cabin Cabin, only this life ecological experimental cabinet can provide five experimental platforms, and multiple experimental objects can be available on each platform.
Cang Huaixing, a researcher at the Chinese Academy of Sciences Space Application Engineering and Technology Center: You can carry out zebrafish and goldfish algae. Two biology constitutes a very mini -type small ecological unit research. There is also a project that needs to be carried out on the pulmonary cells on it. It is possible that the radiation factors in the sky may change the lung cells and finally evolve into tumor cells. From the cell level, it is cancer. Essence
In addition to the experimental cabinet dedicated to life sciences, there are some "public" experimental cabinets that provide special research conditions, including gravity science experimental cabinets and scientific glove boxes and low -temperature storage cabinets. They can provide space science experiments with experiments More detailed experimental conditions.
In addition to the experimental cabinet in the cabin, many space exposure platforms are also arranged outside the cabin for scientists for experiments in a more open cosmic environment. At present, the entire space station has planned nearly a thousand scientific research projects.
Wang Ke, deputy chief chief of Chinese manned aerospace engineering space application system, Wang Ke, director of the Integrated Technology Center of the Chinese Academy of Sciences Space Application Engineering and Technology Center: On Tiangong No. 1, the target aircraft had a life science experiment. The entire task is less than 500 kilograms, it accounts for nearly one -tenth, only one plant. How to do it now on the space station? You only need to bring this plant growth unit, just a few kilograms of the cost, light, environmental control, data processing. This series of our experimental cabinets is provided. This cabinet is equivalent to a field laboratory. A experimental cabinet can roll up hundreds of scientific experiments.
In order to allow astronauts to complete these tasks efficiently, China Space Station has set up an effective load operation management center on the ground. Scientists designing space experiments can pass the video and other information passed by the space station to see the device debugging and real -time operation progress. Guidance provides guidance.
Guo Lili, a researcher at the Space Application Center of the Chinese Academy of Sciences: We are called remote science or remote operation. Adjust strategies, schemes or parameters to get better results.
For God 14th astronauts, the task of building the National Space Lab has not yet ended. Three months later, the second experimental cabin Mengtian experimental cabin was also launched. After the Mengtian cabin is in place, the scientific research capabilities of the National Space Lab will also be greatly improved.
Zhang Wei, Director of the Applied Development Center of the Chinese Academy of Sciences Space Application Engineering and Technology Center: We look forward to giving birth to the first mouse in space and bred space life. We hope to prepare a large number of new materials to solve the needs of the country. It is hoped that new discoveries or new laws are proposed on major issues such as the origin and evolution of the universe.
When the Shenzhou 14th multiplication group set off in June, everyone said that this was the heaviest multiplication group in the task. Now it seems that the case is true. At 3:30 this morning, the connection was over. The astronauts started a day of work at 8 o'clock. There were a lot of state to set up and test. The carbops in the cabin were subsequently disassembled and installed. The work arrangements were full. After cleaning up, a series of space experiments will be performed immediately, and the outlet activities will be carried out.
"Ask the sky" friends are here. In a few months, the "Dream Sky" partner is about to go to space. We look forward to the day when the three -cabin meeting is basically built in China.
