Tang Hongbo: Waiting for an Eleven-year Space Dream

Few people know that Tang Hongbo, one of the space heroes of Shenzhou XII, was originally just an ordinary air force pilot. After eight years of hard training, he became the captain of the flying brigade. Then he spent five years of youth struggle and became the second batch of preparatory astronauts in China. However, the real space dream kept him waiting for eleven years.

During these eleven years, he came close to realizing his dream countless times, but things were always unsatisfactory and he could not reach the other side of his dream. Recently, he was selected as the reserve pilot of Shenzhou XI, but in the end, he was not selected to fly. But on 20 19, God finally took care of him-he was successfully selected into the Shenzhou 12 mission crew.

"There is waiting again and again in the middle, and this process actually needs persistence and is very long." In countless times of self-doubt, he has been firm in himself, waiting for his space dream to come true for eleven years.

How astronauts sleep: confused feelings and strange sleeping positions

It is indeed a "confused feeling" for astronauts to sleep in space. One of its manifestations is that it is black and white, and the other is that it sleeps strangely.

Black and white means that astronauts sail around the earth in the sky, and the sunrise and sunset in space depend on the time for the spacecraft to orbit the earth once. Sometimes sunrise and sunset alternate many times in 24 hours, so astronauts can't follow the life habit of "sunrise and sunset" on earth, so they have to arrange their work and sleep mechanically according to the hours.

Strange sleeping position means that astronauts can't find the feeling of "lying down" in the weightless environment of space. In the gravity environment of the earth, people are used to setting the direction of gravity as "down" and the direction of "sky" as "up", that is, people often say that "the foot steps on the earth and the blue sky is overhead". But in the weightless environment, people lose the reference coordinates of "up" and "down".

You can't step on the ground, it's surrounded by sky. You can't tell up from down at all, so there is no such thing as lying flat when sleeping. Because you can fall asleep standing, lying or lying on your stomach, astronauts can sleep in the space capsule, hang it on the wall, tie it to the bed, hang it on the beam and lean on the table.

Famous sayings about aviation:

1, it's hard to say what is impossible, because yesterday's dream can become today's hope and tomorrow's reality.

2. Space flight is not a matter for one person or a group of people, but a historical process in which human beings conform to the law in their development.

If God doesn't want human beings to explore the universe, push down the ladder.

Because the structure of the universe is God's most perfect and intelligent creation, nothing will happen if there is no certain maximum or minimum law in the universe.

The whole universe is a federation, and both God and human beings are its members.

6. People don't even know the fraction of the universe, let alone command and control the universe.

7. The sky is vast and the universe is infinite.

We believe that when people leave our planet, they will forget the differences between countries.

9. The universe is a collection of solar systems, and we have every reason to believe that these solar systems are similar.
