According to the China Manned Space Engineering Office
Shenzhou 18号瞄准
It was launched today (25th) at 20:59
The flight crew consisted of Ye Guangfu, Li Cong, and Li Guangsu
Composed of 3 astronauts
Every successful launch
It is inseparable from the efforts of the ground staff
It is also inseparable from the hard work and perseverance of astronauts

On September 21, 1992, China's manned space program was officially established, codenamed "921", and the selection and training of astronauts began.
In 1996, China began to select astronauts from among the pilots in active service. Jing Haipeng, who was still a pilot at the time, also received a notice asking him to undergo a physical examination.
Jing Haipeng: When I closed my eyes and asked the doctor to check my ears, I heard two doctors whispering that this physical examination seemed to be selecting China's first batch of astronauts, and my eyes opened.
After several rounds of repeated screening of more than 1,500 pilots who met the preliminary conditions, only 12 of them finally stood out.
On January 5, 1998, 14 prospective astronauts (including two instructors) gathered from all over China to Beijing Space City. From this day on, China's first batch of astronauts officially took the first step of their own flight journey.

Becoming an official astronaut is not an easy task. During the entire training process, astronauts have to undergo a total of eight types of training, and the first step of training is to learn basic theories.
This study task consists of more than a dozen courses, and the book "Fundamentals of Manned Space Engineering" alone has a thickness of more than 600 pages. This is undoubtedly a huge challenge for these astronauts, who have an average age of 32 years old and have been away from school for many years.
Yang Liwei: Suddenly sitting in the classroom to study, at first I couldn't sit still, and I dozed off, but I couldn't doze off. We made strong tea, and everyone was a big cup of water every day in class, so we couldn't stand it anymore and took the initiative to stand at the back of the classroom for a while.
The theoretical courses are complex and difficult, and astronauts often compare them to a ladder. However, these "ladders" are only the cornerstones of their flight journey. Astronauts also undergo special training that is painful and difficult to adapt. For example-
■ Centrifuge
The centrifuge consists of an 8-meter-long boom and pod that gradually accelerates as the astronauts enter the pod. NORMALLY, A ROLLER COASTER IN A PLAYGROUND PRODUCES AN OVERWEIGHT OF BETWEEN 2G AND 3G, WHILE A CENTRIFUGE CAN PRODUCE AN OVERWEIGHT LOAD OF UP TO 8 G, WHICH IS EQUIVALENT TO 8 TIMES ITS OWN WEIGHT.
During the training, the astronauts have a red button at hand, and if there is an unbearable situation, as long as the button is pressed, the training will stop immediately. To this day, however, not a single astronaut has pressed this button.
■Spinner bed
In order to improve the weightlessness and endurance of astronauts, the Astronaut Scientific Research and Training Center has prepared a series of adaptive training, and the universal bed is one of them. But in the eyes of astronauts, training while lying down is no more comfortable than sitting.
Deng Qingming: Lying on that bed, minus 6 degrees, upside down for 7 days. I couldn't come down on it for 7 days, and I was generally very uncomfortable to eat and drink upside down. After we came out, we measured our height and grew 3 centimeters.
■ Electric swing
Due to weightlessness in space, astronauts sometimes experience symptoms such as dizziness and gastrointestinal discomfort. In order to improve the vestibular function of the astronauts and overcome these discomforts, the training center will conduct a training program for astronauts called an electric swing.
Nie Haisheng: The swing is just dangling back and forth, shaking for 15 minutes, which is much more uncomfortable than a pirate ship. That's why we always say persistence, persistence, is to have the perseverance to persist in these.
■Weightless aircraft
When astronauts are in space, weightlessness occurs due to the weakening of the Earth's gravitational pull. Weightless aircraft are a very effective training method. After boarding, each astronaut carries a parachute on his back and hangs a parachute hook to ensure safety. After the plane took off, it flew ten parabolas in a row within an hour.
Although it was the first time for the Chinese astronauts to participate in this training, their bodies were floating up when they were weightless, but they were all calm and kept doing the prescribed training movements. During the flight, the Chinese astronauts raised the five-star red flag, dreaming that one day the national flag would fly in space.
After more than 5 years of hard training
All 14 reserve astronauts passed the final assessment
Become an official astronaut
It has created a miracle of zero elimination rate
Salute to China's aerospace and Chinese astronauts!
