Character experience

In 1996, he was selected to participate in the space program tests.

In January 1998, he officially became one of China's first astronauts. After years of astronaut training, he has completed the training tasks of dozens of subjects in 8 categories, including basic theory, aerospace environment adaptability, and professional technology, and passed the comprehensive assessment of astronaut professional and technical skills with excellent results.

In 2003, he was selected into the astronaut echelon of China's first manned space flight.

In June 2005, he was selected as a member of the crew echelon of the manned flight of the Shenzhou 6 spacecraft.

In May 2008, he was selected as the Shen-7 astronaut crew.

From September 25 to 27, 2008, the Shenzhou-7 mission was carried out.

At 16:43:24 on September 27, 2008, Zhai Zhigang just started to get out of the capsule, and at 16:45:17, Zhai Zhigang took the first step in space, and at 16:59, he ended the spacewalk and returned to the orbital module.

On June 16, 2021, the flight crew of the Shenzhou-12 manned spacecraft announced that Zhai Zhigang was a backup astronaut.

Chinese astronaut Zhai Zhigang. At 16:34 Beijing time on September 27, Chinese astronauts began the first extravehicular activity of Chinese. At this time, the spacecraft was located over the South Atlantic.

At 16:35:12, the hatch opened. At 16:41, Zhai Zhigang successfully exited the cabin. After hanging the red safety tether hook on the exit armrest outside the spacecraft, Zhai Zhigang was halfway up.

The first spacecraft for Chinese astronauts to go out of the capsule was Shenzhou 7. China's first female astronaut is Liu Yang.

Space station of our country.

Stage astronauts.

The success of the first out-of-space mission is of great significance to us, as it also marks another milestone in the out-of-space activities of our manned spacecraft. <>

In fact, this time the astronaut Liu Boming went out of the capsule.

He is wearing a new generation of flying spacesuit independently developed by China.

And it's specifically designed for getting out of the cabin. In fact, the most important significance of his success is a big victory for our own research and development of the spacesuit, in the past, even if we had the experience of going out of the cabin, but we were also wearing and foreign joint research and development, not simply our independent research and development, but this time Liu Boming's success also proves that our independent research and development of extravehicular spacesuits can also be done. We have also explored this step, which means that our technology has reached this standard, and our technological level has reached another milestone.

Because after all, no matter how much we test whether this extravehicular spacesuit can get out of the capsule smoothly on the ground, but in fact, it is all our assumption, and only after we really pass the practice, can we prove to the world that we have this kind of technology. We are also a very powerful space nation. <>

Moreover, being able to get out of the capsule smoothly also represents a great success of our manned spacecraft mission. Because after our manned spacecraft went into space, the tasks were actually very heavy, and there were various tasks to be debugged and prepared, so the success of this time out of the capsule also means that one of our missions can be successfully completed. And it also proves that dieting, our challenge this time is very difficult, but our astronauts are still very powerful, and our equipment is still very powerful, so we can achieve such a successful victory.

In fact, space activities are not only to be able to play and promote, but also to prove our scientific and technological strength to the world for the exploration of the universe, and the complete success of this out-of-cabin activity means these two, and it is also to prove to our people that we have really done it.

This shows that China has made a huge breakthrough in the aerospace field, and in the aerospace field, our country is already the fastest growing country in the world, and has been ahead of other countries to have a greater breakthrough, I believe that there will be better development in the future.

The significance is very significant, and it also shows that the ability of these astronauts is relatively strong, and it also shows that space technology is constantly developing, and then we can better understand space, and this is also a great progress in human technology, and it can also improve the international status.

This activity is of great historical significance, and it can also make further progress for China's aerospace industry, and at the same time, it will also improve the quality of astronauts. It also made this out-of-cabin activity gain more affirmation and recognition. At the same time, it is a step closer to the research of China's space station in space, and it has also laid great historical significance.

This shows that our aerospace technology has been improved, and it is also very mature, so these astronauts can be a complete success, and it also shows that our future is very promising.

It should be noted that the human body should not be exposed to outer space, and protective clothing should be worn to ensure the best oxygen, as well as temperature control, communication equipment, and friendly communication, and do a good job of protective tools, and close the connection with the spacecraft.

It is necessary to pay attention to the safety measures, pay attention to the task of getting out of the cabin, pay attention to the environment, carry out the simulation training of the slag, and also make preparations in all aspects, and understand the external environment.

Be sure to pay attention to safety issues, they usually carry pistols when they go out of the cabin, and they should also pay attention to the temperature and radiation when they know the route, and they should also avoid the debris flying to rush into the trapped section.

Shenzhou-14 astronauts Chen Dong and Liu Yang completed the first out-of-cabin mission.

At 18:26 Beijing time on September 1, 2022, Chen Dong, an astronaut of the Shenzhou-14 crew on the Chinese space station, successfully opened the exit hatch of the airlock module of the Wentian experimental module. By 19:09, astronauts Chen Dong and Liu Yang successfully exited the capsule. With the support of the small robotic arm, the two astronauts will carry out the installation of the extended pump unit of the Wentian experimental module and the lifting of the panoramic camera of the Wentian experimental module, and carry out the verification of the emergency return capability of the extravehicular autonomous transfer.

This is also the first time that astronauts have "gone out" from the airlock cabin of the Wentian experimental module.

China's space station is built independently by China, and all products, components, raw materials, and key core components are 100% independent and controllable. It is worth mentioning that in the out-of-cabin activities before the era of China's space station, the "lifeline" connecting astronauts to the space station - the safety tether - was limited in length. For example, in the Shenzhou 7 mission, when astronaut Zhai Zhigang completed China's first out-of-cabin activity, the effective length of the safety tether was only more than 1 meter.

In the space station construction mission, astronauts have to complete the space station equipment installation, trembling reed maintenance and other out-of-cabin tasks, which have a larger out-of-cabin range, higher operational difficulty and stricter safety requirements.

In the process of leaving the capsule, the length of the safety tether has exceeded 10 meters, and under the innovative design of the R&D team, this safety tether will not only not hook the spacesuit and interfere with the movement of the astronauts, but also withstand the test of harsh environments such as nearly 200 degrees of temperature difference and space irradiation in space. It can also achieve constant force retraction and release, which ensures the convenience and mobility of astronauts.

Hello. At 0:33 on September 2, 22, Beijing time, after about 6 hours of out-of-cabin activities, Shenzhou-14 astronaut Chen Dong.

Liu Yang, Cai Xuzhe.

Complete all the scheduled tasks, and the out-of-cabin activities were a complete success. The Shenzhou-14 crew went out of the capsule for the first time, and at 18:26 on the 1st, astronaut Chen Dong, wearing a blue ribbon extravehicular spacesuit, successfully opened the Wentian experimental module.

Airlock cabin exit hatch.

With the cooperation of astronaut Liu Yang, Chen Dong completed the installation of the foot limiter and the extravehicular console.

At 19:09, astronaut Liu Yang, wearing a yellow ribbon extravehicular spacesuit, successfully exited the capsule.

Astronaut Chen Dong: This is the first time that an astronaut has exited the airlock, and it is also the first time to use the forearm, and it is also the first time that 02 and I have been out of the cabin. Among so many firsts, we felt the beautiful scenery outside the capsule, the difficulty of getting out of the capsule, and the Chinese space station.

Growing stronger.

Astronaut Liu Yang: Thank you comrades-in-arms for your help, thank you for the support of all scientific and technological personnel, and thank you for the attention of the people of the whole country. Heaven and earth are one step forward, although it is full of hardships and challenges, but every small step forward is a big step for dreams.

China's space station is always worth looking forward to. Than the heart.

Than the heart. Astronaut Cai Xuzhe: Thank you Shuguang and the vast number of scientific and technological workers for their support for this mission, and also congratulate you on completing your first mission.

This is the fifth time that the Chinese space station has been out of the capsule, but it is the first time that the Chinese space station has entered the construction stage, so there are many differences compared with the previous ones. For example, this is the first time that astronauts have exited the airlock of the Wentian experimental module, the first time to board a small robotic arm, and the first time to move autonomously outside the Wentian experimental module, and to complete five major items and eight installation steps, which can be said to be complex and arduous.

Astronaut Liu Boming successfully opened the exit hatch of the node module of the Tianhe core module, and Liu Boming and Tang Hongbo successfully exited the cabin in the new generation of Zhongliquid "Feitian" extravehicular spacesuit independently developed by China. This exit is the first exit after nearly 13 years after the Shenzhou 7 mission in 08, and it can be said that it is very different from the verification exit that lasted only a few dozen minutes that year! This time the exit lasted several hours, and it was an application EVA, and it was a real construction task completed by several hours of activities outside the cabin.

Let's enjoy our beautiful Earth with astronauts! After completing the operation of lifting the panoramic camera, Liu Boming buried his helmet camera at the earth and explained: "Now there are white clouds, and there are patches of pictures like the ocean.

Now, follow my footsteps and fly freely together. ”

After about 7 hours of out-of-cabin activities, the Shenzhou-12 astronaut crew worked closely together to successfully complete all the scheduled tasks during the out-of-cabin activities, and astronauts Liu Boming and Tang Hongbo returned safely to the Tianhe core module, marking the complete success of the first out-of-cabin activities of astronauts in the stage of China's space station.

China's first astronaut to carry out out-of-cabin activities: Zhai Yu and Li Zhigang. On September 25, 2008, Chinese astronauts Zhai Zhigang, Liu Boming and Jing Haipeng took the Shenzhou-7 spacecraft to space.

At 16:43:24 on the 27th, Zhai Zhigang just started to leave the capsule, and at 16:45:17, he took the first step in space, and at 16:59, he ended the out-of-cabin activity and returned to the orbital module. On the 28th, the Shenzhou 7 mission returned to Earth by the formation of Zhenque Chigong. Zhai Zhigang became the first Chinese astronaut to walk in space, and the 354th astronaut in the world to walk out of the capsule.

Out-of-capsule astronauts have to perform the task of installing arm brackets. One of them has to install an upper arm bracket for the robotic arm, and the other astronaut performs auxiliary work at the operation point, and conducts an emergency return verification in the middle.

They still have a very clear division of labor this time, two of the astronauts need to install brackets for the machinery, and the limiter tool table finally needs to move with the help of the mechanical arm, and the last astronaut needs to install handrails, and must crawl a distance to be able to work, which also needs to return to verification, which is still very difficult, and requires them to cooperate with each other.

It is necessary to install the bracket on the wall, the angle limiter, the tool table, the handrail needs to be installed, the work needs to be carried out at the operation point, and the other needs to be returned to verify in an emergency, and the work is relatively busy.
