Confusion 丨 Why are the astronauts mostly three people?

Author:Chinese aerospace Time:2022.08.17

On April 12, 1961, the world's first manned spacecraft "Orient 1" sailed at the Soviet Byk Nur launch center. For the first time, Gagarin realized the feat of humans traveling in space.

In 2022, 61 years have passed since the first breakthrough of human beings to break through the atmosphere. The advancement of science and technology has brought a new lifestyle, and cutting -edge technology has promoted human exploration of the universe. Since Shenzhou 8, in the past 11 years, the "Shenzhou" series of spacecraft has successfully implemented 10 flight missions.

In recent years, my country "Shenzhou" manned flight mission list

1

Shenzhou 12 manned flying task

3 astronauts: Nie Haisheng, Liu Boming, Tang Hongbo

2

Shenzhou 13 manned flying task

3 astronauts: Zhai Zhigang, Wang Yaping, Ye Guangfu

3

Shenzhou 14 manned flying task

3 astronauts: Chen Dong, Liu Yang, Cai Xuzhe

In November this year, Shenzhou No. 15 manned spacecraft will also send 3 astronauts to the space station. They will carry out a 10 -day work transfer with 3 astronauts including Chen Dong who arrived early.

Seeing this, I believe everyone can doubts:

"Why are there always three people in space 'travels' in recent years?"

"Why are the combinations of 2 men and 1 woman?" ...

These questions, we will answer it here.

1. In recent years, "business trips" Chinese space station astronauts

Why are there a group of 3 people?

In response to this issue, Tao Jianzhong, a senior aerospace expert and a researcher at the Institute of Shanghai Aviation System Engineering Research Institute.

"It is not easy for the Shenzhou to carry a spacecraft to go to the China Space Station. It can be equipped with up to 3 people. From a cost perspective, the maximum cost -effectiveness can be achieved. The division of labor of the 3 astronauts is also different. Scientific experiments. 3 people also have a companion to each other, otherwise they are too lonely. "

Tao Jianzhong introduced that this is also an international practice. The Russian Alliance spacecraft is equipped with a maximum of 3 people, and the US -manned dragon spacecraft is equipped with a maximum of 4 people. They also adopt the "full" loading capacity when they go to the International Space Station.

2. Why are the combination of two men and one woman?

Tao Jianzhong said:

"Women push up the" Half Sky "of human society. There are dozens of female astronauts in the world's countries, and Chinese space stations are indispensable for female astronauts."

For a long time, the number of female astronauts is less than the male astronauts, mainly because women are relatively low in threshold for women to withstand the radiation of cosmic radiation, but women astronauts are more careful when they complete the tasks such as scientific experiments, which is conducive to long space. During the task, give full play to the unique advantages of women.

It is reported that the United States, China, and Russia are developing a new generation of manned spacecraft that can carry 6-7 people. In the future, astronauts will be more lively to go to space for "traveling".
