my country calls astronauts as astronauts because we have not boarded the moon?Talk nonsense

How do we call them those who take the spacecraft to perform missions? astronaut? That's right, but we often hear another title, that is, "astronauts". What is the difference between the two?

In fact, there is no essential difference between astronauts and astronauts, but "astronauts" are unique to our country. So why do the world call "astronauts", only we call it "astronauts"? Maybe you have heard such a saying: "The reason why we call the astronaut is because our astronauts have not set foot in the moon." For this statement, we can only be described in two words, that is, " absurd". So is astronaut and astronauts' names translation? Not, the two titles are not only different in Chinese, but also different in English.

The name of astronauts was available as early as 1961, and it was proposed by the former Soviet Union.

On April 12, 1961, the first astronaut in human history was born. He was Yuri Gagarin. Former Soviet Union became the first country in the world to achieve manned space. The people who go to space in the spacecraft are called "cosmonaut", and the vocabulary is derived from Greek, which means "the whole universe", and the "astronaut" is called for birth. It can be seen that the first time human beings went to space, there was the title of "astronaut", and not to mention that the mankind was on the moon. Astronaut "" is purely talking. Astronaut's English words are "COSMONAUT", and the English words of Chinese astronauts are "Taikonaut", which is obviously different.

The origin of the word "astronaut" in my country was actually proposed by Mr. Qian Xuesen, and it has now become a characteristic of Chinese aerospace.

The reason why Mr. Qian Xuesen put forward the title of "astronaut" is actually a continuation. Because my country has a navigator and airliners, there should be a spaceman. Just now we mentioned the English word of the astronauts. The word is actually very interesting, because the pronunciation of some of the taiko in front of Taikonaut is just similar to "space". Therefore, don't doubt the title of astronaut and astronauts, the latter is a characteristic title of our Chinese aerospace, which has nothing to do with other things. When it comes to astronauts, we will think of the three astronauts in heaven recently, Chen Dong, Liu Yang and Cai Xuzhe.

On June 5, 2022, Shenzhou 14 spacecraft was equipped with 3 astronauts to space. After 10 days, on June 16, Chen Dong, Liu Yang and Cai Xuzhe successfully entered the sky and the core cabin.

Three astronauts will live for 6 months on it. Why is it so long? In fact, it is not the first time that my country's astronauts have stayed on the space station for a long time. Shenzhou 12 is on the track for 3 months, and Shenzhou 13 astronauts who launched the launch in October 2021 have already implemented Six months of track work, this time Shenzhou 14 is also 6 months. The reason why astronauts need to perform the time of the CEO for a long time to achieve the benchmarking with the International Space Station. For the International Space Station, the 6 -month resident period itself is a normalized residence cycle. Later, 6 months will also be the shortest stay.

What do you want to do in space for 6 months? In fact, there are many things that astronauts have to do.

When entering the space station at the beginning, the first thing the astronauts had to do was to establish a resident environment. The first step in establishing the environmental environment is to sample various environments in the space station, such as air microbial sampling, water microorganisms, and surface microorganisms, etc. Maintenance equipment is maintained. Throughout the stay, carried out spatial science experiments and technical tests is one of the main tasks of astronauts. When it comes to space science experiments, it is necessary to mention a important task of Shenzhou 14, that is, to build the National Sky Lab.

The National Sky Lab is mainly divided into two modules, that is, asking the sky experiments and the Dream Sky Experiment.

The main function of the Mengtian experimental cabin is to conduct micro -gravity experiments. We know that the most obvious difference between the sky and the surface is a weightless environment, so many experimental items that cannot be performed on the surface can be performed in space, such as cultivating space seeds and performing micro -gravity metallurgy. Taking metallurgy as an example, due to the impact of gravity on the surface metallurgical, because the density of different metals is different during production, it is difficult to achieve uniform fusion. Metallurgical experiments do not have this problem. According to previous experimental data, the performance of space alloy can even reach more than 10 times that of ordinary alloys. It can be seen how significant the launch of space science experiments.
