After the astronauts died in space, why can't the remains be transported back to Earth?

Humans always have a strong interest in exploring the unknown, and because of the unknown, they seek knowledge. The same is true for spaceflight activities. For us, it is a special and mysterious occupational activity. In such a special and unknown environment, every step of exploration is arduous and difficult. is the price of life.

The birth of astronauts in this profession comes from this. Their existence is to serve the exploration of outer space. It is required that the quality and education level of the selected personnel are the best, and they can not only withstand the harsh aerospace environment. , but also have profound knowledge and skills to deal with various unknown situations.

In the history of human spaceflight, the first astronaut to enter space was Yuri Gagarin of the Soviet Union. In the 1960s, he took the Vostok 1 to enter outer space for the first time, starting the history of human spaceflight. new chapter.

In our country, the first astronaut was Yang Liwei who entered space aboard the Shenzhou V spacecraft in 2003. This has profound significance for the development of China's aerospace technology, and it has revealed a mysterious veil of space, which is a milestone in China's aerospace history. It provided a certain degree of theoretical knowledge of outer space for the subsequent launches of Shenzhou No. 6, No. 7 and No. 10.

Space is a fascinating place because it is very different from the earth environment. Under air, gravity and space radiation, even if scientists make various assumptions about what may happen, practice is always more important than theory. Expeditions in unknown outer space will never have all assumptions and solutions.

Therefore, since there are unknowns, there will be dangers and accidents. Even the two countries with rich experience, the United States and the Soviet Union, have experienced many accidents. After the astronauts died, their bodies could not be transported back to Earth due to various considerations.

After Yang Liwei entered space, when he returned to the earth, he was injured because of some violent friction between the flight capsule and the earth's atmosphere, resulting in a resonance between the two. What's more, it is directly dead, and in space, due to the influence of space radiation, astronauts' bodies may undergo changes that we cannot know about, because the elements in space and the earth are very different, The consequences will be beyond our control, causing irreparable damage to the planet.

Therefore, due to various safety considerations, after the astronauts are killed, their remains cannot be brought back to the earth. Perhaps, for every astronaut, this may be the result that he has expected when he chooses this special and great profession, but they still insist on the love and loyalty of this profession, which is worth our visit admire.
