Quick View
The construction process of the Chinese space station is intensive. my country's first astronaut Yang Liwei recently mentioned a vivid description in his speech at Xiamen University - stubbornly propulsion . It can be said that it is linked together, and no mistakes can be allowed in every step.
- launched the Tianhe core module on April 29, 2021, and launched the Shenzhou 15 manned spacecraft at the end of this month. After one year and seven months, all the established tasks of China's space station construction will be completed.
- launched 11 times, including: 3 launches in the cabin, 4 launches in the cargo spacecraft, and 4 launches in the manned spacecraft.
- uses three types of rockets to launch in two places, launching Fat Five B and Long Seven in Wenchang , and launching Long March 2F in Jiuquan.
- implements multiple combination configurations, rendezvous and docking, separation and evacuation of the tank section.
finally realizes the three-cabin T-shaped configuration of " days and core cabin + Wentian experimental cabin + Mengtian experimental cabin ".
days and core cabin are not the first steps. I have created many "first"
can actually launch the sky and core cabin, which shows that the construction of space station has been on track, and before that, my country has also done a number of pre-match preparations.
China's first manned flight
In 2003, Yang Liwei rode the Shenzhou V manned spacecraft , entering space for the first time and successfully returned.

Chinese astronauts left the cabin for the first time
008, Shenzhou 7 crew astronauts Zhai Zhigang completed the first Chinese out of the cabin in space. China's first target aircraft - Tiangong 1
launched Tiangong 1 in 2011, which can be said to be the verification version of Tianhe core cabin.
China's first space rendezvous and docking
In November of the same year, Shenzhou 8 was launched, successfully connecting with Tiangong-1 on-orbit rendezvous and docking; then in 2012 and 2013, the Shenzhou 9 and Shenzhou 10 manned crews were launched, and Shenzhou 10 successfully completed the first automatic rendezvous and docking.
China's first real space laboratory
launched Tiangong 2 in 2016. It can be said to be the verification version of the Wentian Experimental Cabin and Mengtian Experimental Cabin. Then it was docked with Shenzhou 11 manned spacecraft and Tianzhou 1 cargo spacecraft , verifying the ability of many people to be in orbit for a long time (2 people 1 month) and cargo up and down. This made a preliminary verification for the subsequent launch and docking of Shenzhou 12~15 and Tianzhou 2 ~5.

11 launches and stubborn propulsion process of China's space station
During decades of preparation, when time comes to 2021, we Chinese have started to build our own space stations in full swing. These two years can be said to be the highlight of China's aerospace , and the whole world has focused our attention on us.
1, Tianhe Core Cabin Launch
On April 29, Tianhe Core Cabin Launched. Here is a little trick to remember. , the troops will go to before they move their food and grass. In the future, they will launch freight spacecraft first, that is, deliver express delivery, and then launch manned spacecraft. For example, Tianzhou 2 corresponds to Shenzhou 12, and so on, Tianzhou 5 corresponds to Shenzhou 15.

2, Tianzhou-2 launch for verification
On May 29, Tianzhou-2 launch for independent rendezvous interface with Tianhe core cabin backward interface. Simply put, it is to deliver materials to the Shenzhou-12 crew in advance and verify Tianzhou-3 , 4 and 5.
Of course, this is not the only task. There are two important verification tests to be done later: First, after the Shenzhou 12 crew arrives at the space station and evacuates, Tianzhou 2 moves from Tianhe's backward to forward-ward interface and connects again. Because Tianzhou 3 also has to go through the same operation steps, it focuses on verifying Tianzhou 3.Second, before Tianzhou 2 evacuated the space station, the Shenzhou 13 crew conducted an index test with the assistance of the robotic arm, which was for the in-orbit indexing of the Wentian and Mengtian experimental cabins in the future.

3, Shenzhou 12 launch and evacuation
On June 17, Shenzhou 12 launched and independently and quickly rendezvoused and connected with Tian and forward pair interfaces. This has been verified on Shenshen 11 and this time their tasks are very arduous and complex, such as daily operation and maintenance, testing of large robot arms, and two out-of-cabin activities. These verification work will be encountered in Shenzhou 13 to 15 in the future.
In addition, Shenzhou 12 also carries two important tasks: one is to circumnavigate the space station for the first time when it is working in orbit for three months, and to achieve the first radial rendezvous and docking verification with the space station, because the Shenzhou 13 and Shenzhou 14 behind must dock in this way. The other is to check the search and recovery capabilities of Dongfeng landing ground for the first time. Later, Shenzhou's 13th to 15th returned, and they also had to be recycled at the Dongfeng landing ground.

4, Tianzhou 3 launches
On September 20, Tianzhou 3 launched and docking with Tianhe. This is the first time that the cargo spacecraft has been transported upward with full load. Why? Because the upcoming three-person crew of Shenzhou No. 13 will be in orbit for 6 months, and there will be more natural supplies. Tianzhou-3 did not evacuate the space station until July 17, 2022, and became the cargo spacecraft that has been in space for the longest time.

5, Shenzhou 13 launch
On October 16, Shenzhou 13 launched and docked with Tianhe. For the first time, a female astronaut entered the space station, and it was the first time that a female astronaut left the cabin. During the orbit, the crew carried out three out-of-cabin activities, carried out Space Class , and carried out the regular residence of astronauts for 6 months for subsequent formal operations. At this point, the verification phase of China's space station has come to an end and will usher in the subsequent busy assembly work.

6, Tianzhou 4 launches
into 2022. On May 10, Tianzhou 4 express delivery was issued, and the subsequent Shenzhou 14 crew was sent in advance to deliver food and grass at the station.

7, Shenzhou 14 launch
Shenzhou 14 crew is called the "busiest crew". It is not an exaggeration to see if Shenzhou 14 was launched on June 5, and the crew crew members were composed of three second batch of astronauts at the same time for the first time. During their six months in orbit, they had to go through nine configurations, five docking and three evacuations. The most important ones are: welcome Wentian, Mengtian, and Shenzhou 15 crew. During this period, they went out of the cabin three times on September 1, September 17 and November 17 respectively.

8, Wentian Experimental Cabinet launches
Wentian is the first experimental cabin of China's space station and the largest single spacecraft in China. It was launched on July 24 and successfully docked with Tianhe the next day.

9, Mengtian experimental cabin launch
Mengtian experimental cabin is the second experimental cabin. It was launched on October 31, and successfully docked with Tianhe the next day. It was successfully transferred 2 days later, and the three-cabin T-shaped configuration of the Chinese space station was officially formed.

10, Tianzhou 5 launch
1 On November 13, Tianzhou 5 express delivery arrived at the space station, which means that the Shenzhou 15 crew is about to arrive.

11, Shenzhou 15 launch
According to public information, Shenzhou 15 will be launched around November 29, which is also the last step in the construction phase of China's space station. Which three astronauts will enter space and realize the six-man team of the Chinese space station for the first time? Let's wait and see.

conclusion
Do you feel dazzled after watching it? In one year and seven months, our intensive launch in such a stubborn manner will soon welcome the Chinese people's own space station at the end of 2022. As Chinese, we are proud of our self-improvement.
