Preface
In just 28 seconds of video, the sonorous countdown under the background music is exciting, and with the end of the dance, Shenzhou 18 was successfully launched!
At that moment, everyone's efforts were recognized!

However, the Shenzhou-18 launch trip was given a great responsibility, and the astronauts who went to space with it were also shouldered.
So, what exactly is the mission of Shenzhou-18 and what does it mean for China?
On the night of April 25, the Jiuquan Satellite Launch Center was pitch black, but when the firelight appeared, the surrounding area was instantly illuminated, and this trick directly illuminated the hope buried in people's hearts.
People stared at the light in the darkness, and saw the fire grow smaller and smaller until it disappeared into the night sky.
In just 10 minutes, the Shenzhou-18 manned spacecraft successfully separated from the rocket and successfully entered orbit.
As soon as this news came out, it pulled the hearts of thousands of people, although such scenes have long been commonplace, but when people see them again, the excitement is difficult to calm down for a long time, which has extraordinary significance for scientific researchers and astronauts.
But there are also netizens who disagree, bluntly saying: It's not as good as the "fireworks" set off in Japan next door. But it's just a joke, and everyone who understands it must understand the deep meaning.
You must know that China can have such brilliant achievements in the aerospace industry, not by luck, but by strength!
In 1956, with the birth of an announcement, the mainland's first missile and rocket research institute appeared in front of people, and at the same time, it also represented the starting point of China's aerospace industry.
After 28 years, China has its own missiles and artificial satellites, but how can China be "satisfied" with this?
In 03, the Shenzhou 5 manned spacecraft came out for the first time, which directly shocked everyone, as if in a dream, never thought that people could go to space!
However, people's reason is not swayed by emotions, after a short period of excitement, their hearts are full of worry and incomprehension, you must know that once the launch of Shenzhou 5 fails, everyone's efforts will be in vain.
The most important thing is that the manned spacecraft, as the name suggests, is to carry people into space, which is an unprecedented challenge for China, and if it fails, it will threaten the lives of astronauts.
Even so, the launch of Shenzhou 5 was still carried out as originally planned, but what people feared did not happen.
People's worries are really too much, because China has been preparing since '99, building Shenzhou-1 first, but only for experiments, test flights, and researchers get data from it, and this has laid a good foundation for Shenzhou-5.
In the end, Shenzhou 5 was successfully launched in 03, and astronaut Yang Liwei became the first person in China to go to space.
The success of Shenzhou-5 set a new milestone for China's space industry, and at that time, China became the third country in the world to independently master manned space technology after the United States.
It took only three years for China to fly one person into space and then to a multi-day manned space flight for many people, while it took two years for astronauts to go out of the capsule.
As we all know, it is difficult for people to survive in space, but what people never expected is that China actually built a space station in space, and I can't help but feel that there is nothing that China can't do, maybe there will be bigger surprises behind.
And this Shenzhou 18, not only to send astronauts to space, but also to shoulder a major task, once successful, the mainland is likely to create brilliance in the aerospace industry and even in many fields!
When Shenzhou-18 arrives at China's space station, it means that the Shenzhou-17 astronauts, who have been on a business trip for half a year, will return home, and their positions will be taken over by the Shenzhou-18 astronauts.
They are Ye Guangfu, Li Cong and Li Guangsu.
Among the three astronauts, Ye Guangfu, as the second astronaut, has a heavy responsibility and is the core figure in the team.
The three of them can be said to be a strong combination, and this time they are also prepared, and the small controlled experimental group and ascending aquatic support device carried on Shenzhou 18 will play a vital role in China's first orbital aquatic ecology research project.
After the selection of scientific researchers, zebrafish and goldfish algae were used as experimental subjects.
When people heard this, they were full of doubts, the launch of Shenzhou 18 into space was just to be able to raise fish in space? Why not raise them on Earth, what is the difference?
Taking the research subjects as an example, the genetic similarity between zebrafish and humans has reached 87%, and then looking at goldfish algae, which can not only provide oxygen, but also purify water and absorb excess nutrients.
The experiment began when the astronauts placed the subject on the device, in which the ascending aquatic support device acted as a light source to encourage the plants to photosynthesize and produce oxygen so that the zebrafish could survive.
But what's the point of doing that? When the experiment is carried out, the ecological experiment module that was mentioned at the beginning needs to form a closed-loop equilibrium system, and at that time there is an indispensable relationship between zebrafish and goldfish algae.
When goldfish algae is irradiated by a light source, it produces oxygen to keep zebrafish alive, and goldfish algae lives on the feces excreted by zebrafish, and so on.
Once this experiment is successful, it means that China is likely to create multiple "firsts"!
What people never expected was that researchers had been preparing for 4 years in order to be able to raise fish in space!
In the past 20 years, scientists have begun to select suitable test subjects, and then they have begun to study how to provide oxygen and how to feed them.
Now, the fact that this project can be implemented in the space station and the Shenzhou 18 manned spacecraft can be said to have an indispensable contribution to their efforts.
For scientists, the project is of great significance, because in addition to the data transmitted by the astronauts, the surface personnel will record the data in detail through the cameras on the experimental system to understand the impact of the space environment on the ecosystem.
It is believed that China's space industry will soon usher in a new milestone, after all, astronauts have successfully planted lettuce, wheat, rice and so on in space before.
As of 23 years, there have been 110 experiments carried out in the space station, and the data memory they have obtained through observation, testing and research is as high as 100TB, which shows that every subtle data is extremely important for scientific researchers.
epilogue
Congratulations on the successful launch of Shenzhou 18, and hope to hear good news from the space station later. At the same time, I wish every astronaut a safe return to the ground after the mission.
