When Shenzhou VII leaves the capsule, he will display the national flag at all costs. Do you know how difficult it is to leave the capsule?

Astronaut Liu Boming Shenzhou VII was in distress when he left the cabin. At that time, the hatch could not be opened. In desperation, Liu Boming found a metal stick and pried Zhai Zhigang's door open. When preparing to leave the cabin, the fire alarm sounded, and the three astronauts decided to change the procedure of leaving the cabin and fly the national flag first. Liu Boming recalled that he was ready to sacrifice at that time: "We just want to show the five-star red flag to prove that we have been here!"

After the reverse propulsion engine of the Shenzhou 12 manned spacecraft was successfully ignited, it landed safely in the predetermined area of the Dongfeng landing site. Astronauts Nie Haisheng, Liu Boming and Yang Hongbo, after 90 days of space work, finally successfully completed their tasks and returned to the motherland.

China people's dream of flying for thousands of years, a milestone in China's space industry, has been given a brand-new meaning today. 2021September 17: The universe roams, and space life is no longer exclusive to foreigners. The technology of freely shuttling between the universe and the earth has gradually matured, and China people and China's space industry have finally ushered in another major technological breakthrough.

Shenzhou VII is China's third manned space mission, and it is also the first time that three astronauts have entered space at the same time. In the Shenzhou VII flight crew, Zhai Zhigang is the commander, Liu Boming is the operator and Jing Haipeng is the experimenter. They are all flying into space for the first time.

While performing the extravehicular task and showing the national flag to everyone in space, they were ready for sacrifice. 2008 is destined to be an extraordinary year, with snowstorms in the south, Wenchuan earthquake, Beijing Olympic Games ... all kinds of major events one after another, and the national spirit is in a state of high tension.

The highly anticipated launch of China's seventh manned spacecraft, Shenzhou VII, opened China's third manned space mission. This is also a key link in the second stage of China's "three-step" space development strategy. Astronauts have to complete several tasks, including extravehicular activities and asteroid flight, and break through many technical bottlenecks.

Zhai Zhigang is wearing the first generation of "Tian Fei" extravehicular spacesuit made in China, and Liu Boming is wearing the "Yinghai" extravehicular spacesuit made in Russia. As this is China's first spacewalk mission, everything is unknown. In order to ensure the completion of the mission, two astronauts wore extravehicular spacesuits and conducted a series of simulation experiments in the space capsule.

After a lot of preparation, the two astronauts closed the return module and depressurized the orbital module to make its air pressure close to that of outer space. But just as Zhai Zhigang was about to open the hatch and enter space, something unexpected happened. No matter how hard Zhai Zhigang pulls the hatch, he just can't open it, which has never been encountered in the pool simulation experiment on earth. The hatch should open easily. At this time, Liu Boming found a crowbar for Zhai Zhigang in the orbital module and finally pried open the hatch.

The hearts of the three astronauts are shaking. At that time, countless conjectures flooded into their minds, but none of them reassured them. What should I do, keep driving or give up? If it continues, the consequences may be unimaginable. If we give up, billions of people all over the world will look at us, but we will lose the face of all China people.

Although countless ideas are running in my mind, what I see in the live broadcast is still unhurried and confident. When they pulled the hatch together again, the hatch without a crack finally opened a slap in the face. However, before they could make the next move, the small seam closed as quickly as if they were conscious, which made the astronauts' hope of leaving the cabin go up in smoke.

The hearts of the three astronauts are still held high. If there is something wrong with the equipment, if the crowbar and the door rub to produce sparks, then don't say cabin activity. The whole orbital module may explode, and they may disappear into space in front of people all over the world. At that time, in the universe, on the ground, everyone was caught in unprecedented tension and fear.

Jing Haipeng in the cabin, almost at the moment when the alarm sounded, immediately launched an investigation. Two comrades-in-arms outside the cabin and his own life, as well as the hope of China, are all pinned on him. He can't panic, also dare not panic. At the same time, the extravehicular Zhai Zhigang and Liu Boming also reached a * * * knowledge, even writing with life, the glory of this moment is worthwhile.

The astronauts of Shenzhou VII have put life and death at risk, and their first thought is to finish the task no matter what. After calming down, Zhai Zhigang suddenly thought, how could the orbital module catch fire? Because of the spacewalk, the orbital module has been depressurized, and there is no oxygen in it, so it should not burn.

So, they continued to carry out the spacewalk mission. But in order to prevent accidents, the astronauts disrupted the original plan, and Zhai Zhigang took the lead in showing the world a five-star red flag. Zhai Zhigang and Liu Boming decided to let China's national flag fly in space even at the expense.
