The Long March II F- 12 carrier rocket carrying the Shenzhou 12 manned spacecraft was launched on time and successfully entered the scheduled orbit.

15: 54, the Shenzhou 12 manned spacecraft successfully rendezvous and docked with the Tianhe core cabin, and the whole rendezvous and docking lasted 6.5 hours.

Many people watched the live broadcast and were excited at the moment when the launch was successful.

The manned space launch mission consists of three astronauts, who will stay in space and start a three-month work mission in the core cabin.

This year is a year of frequent space launch missions in China. The interval between several major launch missions is short, and the technology of China's space industry is constantly improving.

This time, the rapid autonomous rendezvous and docking technology means that the command and control of ground staff are not needed. Shenzhou 12 spacecraft can rendezvous and dock with Tianhe core cabin completely independently and quickly, which can greatly reduce the rendezvous and docking time and the working pressure and intensity of ground staff.

From "Chang 'e" accompanying the moon to "Zhu Rong" successfully setting foot on Mars, China has won one victory after another in outer space exploration and accumulated a lot of successful experiences.

China's space launch success rate is also the highest in the world, which has also established confidence for the development of China's manned space program.

We can proudly say that China has entered the ranks of space powers.

China formulated a three-step development strategy for manned space flight in 1990s.

The first step is to launch a manned spacecraft, build a preliminary supporting experimental manned spacecraft project and carry out space application experiments;

The second step is to break through the astronaut's extravehicular activity and spacecraft rendezvous and docking technology, launch a space laboratory, and solve the space application problem with a certain scale and short-term care;

The third step is to build a space station to solve the problem of large-scale and long-term space application.

The successful launch of Shenzhou 12 manned space flight shows that the mission set in the third step has been achieved.

It can be said that it is the prelude to the on-orbit scientific research experiment of China's self-built space station.

Then there will be a series of manned launching missions, and more astronauts will station in the space station to carry out corresponding scientific experiments.

According to the Blue Book of Space Science and Technology Activities in China (2020) issued by China Aerospace Science and Technology Corporation, the number of space launches in China is expected to exceed 40 for the first time in 20021year.

In 20021and 2022, China's manned spaceflight project is expected to carry out 1 1 launch missions.

The manned space station project has entered a critical implementation stage and is the top priority of the annual space mission.

It has completed five launch missions of Tianhe No.1 core cabin, Tianzhou No.2 cargo spacecraft, Shenzhou 12 manned spacecraft, Tianzhou No.3 cargo spacecraft and Shenzhou 13 manned spacecraft.

As can be seen from the arrangement plan, the Shenzhou 13 manned space launch mission is also in full swing, and China is making every effort to build a space station.

It also proves that our journey is a sea of stars.

Seeing China's achievements in the aerospace field, I believe everyone in China is proud and extremely excited, and the florist can finally hold his head high.

What is the significance of the successful launch of Shenzhou 12 manned spacecraft?

I don't know if you have thought about this question.

We spend so much manpower, material resources and financial resources to build our own space station, to explore the moon and Mars.

These things seem to have no direct economic benefits, but they are of great strategic significance.

The space station can carry out six research fields: physical science, biology and biotechnology, technology development and verification, human research, earth and space science, and educational activities and promotion.

It can fill the shortcomings of China's research in these fields and strengthen China's right to speak in the development and construction of outer space.

It is also for the future manned landing on the moon to do technical research and reserve, and further, it can also be used as an outer space transit station for manned landing on Mars in the future.

In the past, China was in a state of backwardness, imitation and follow-up in key high and new technologies. In recent years, China has made breakthroughs in some core technical fields, which has also strengthened China's ability in space exploration.

China's series of achievements in space can be said to have broken the course of monopolizing human space history with the United States and the Soviet Union as the mainstay since 1950s.

Only after experiencing darkness can we feel how gorgeous the sunshine at dawn is.

In the 1970s, the former Soviet Union and the United States both built their own space stations, which were the products of the arms race in the Cold War era. They both settled in astronauts and conducted a lot of scientific research.

After the disintegration of the Soviet Union, Russia also restarted the construction of its own space station, and the United States also proposed to build its own space station. These two views are consistent in many places.

Then there is the International Space Station. 1998 started construction, and 20 10 was put into full use. At present, the International Space Station is built, operated and used by 16 countries.

China was not among the countries that built the International Space Station, and China was not invited to build it at that time.

I believe everyone knows the reason, and each has his own opinion, so I won't expand my personal thoughts here.

At that time, China was too poor and weak to build its own independent space station. The construction of the space station can only postpone this plan. After all, China can't even put a man into space.

After the disintegration of the former Soviet Union and the end of the Cold War, under the control of the United States, 33 countries, mainly western countries, signed the Wassenaar Agreement in Vienna, Austria.

To put it bluntly, this agreement does not allow countries that have signed the agreement to export military and high-tech products to China without authorization, so as to control China's exports.

China has been suppressed by the western world, led by the United States, in the high-tech field. In the absence of any feasible technical reference, it still depends on the silent efforts of several generations of researchers.

China people don't admit defeat in their bones. As Qian Lao said, China can't do what foreigners can do?

During the Soviet Union, the teacher said the same thing. Just block the technical blockade. After ten years and eight years of blockade, China has everything.

Since 1992, China has successively developed Shenzhou series manned spacecraft, Tianzhou series cargo spacecraft and Tiangong Space Laboratory.

Since the Shenzhou 5 launch in 2003, China people have been in space for the first time.

In 2008, Shenzhou VII was launched, and China people realized spacewalk for the first time ... Until 20021year, the on-orbit assembly and construction of China Space Station was fully launched, and all products, components and raw materials were localized.

There is a long way to go in Xiu Yuan, and I will go up and down.

Now our country has not only broken the technical blockade, but also stood in front as a leader.

The successful launch of Shenzhou XII and the arrival of the first astronaut represent the continuous efforts of mankind in the process of exploring space. The difference is that this time it is a different country and people. It is expected to change the pattern dominated by the United States and Russia in the future.

Soon, China's space station may become the only space station in orbit in the world, and then we will see another scene.

Of course, in the future, China welcomes sincere cooperation countries to use the space station in China to carry out international cooperation, and countries interested in space project research can submit cooperation applications.

This scene seems very similar.

This not only represents the enhancement of China's space development capability, but also represents that China's comprehensive strength is constantly moving towards a new level.

I wish the Shenzhou 12 manned space mission a complete success!
