Human beings have always been very curious about what mysteries are in the universe, but now that science and technology are becoming more and more advanced, some wishes can be fulfilled. For example, nowadays, people have taken a major step in the exploration of the universe and space. You can learn about the universe through some probed satellites or man-made spacecraft. However, we must know that in the process of the development of human science and technology civilization since ancient times, some people have to make sacrifices. For some astronauts, they have made indelible contributions to the exploration of space.
Nowadays, many countries in the world have implemented space exploration, and some of them have launched manned spacecraft, and some countries have even completed the moon landing plan, and the contributions of the astronauts are indelible. In addition, the pressure that astronauts have to endure is also unimaginable by ordinary people. You must know that such an unknown journey is full of dangers and may fall into crisis at any time. Among them, many astronauts have successfully completed it. Space missions, return to the ground, but some people are not so lucky. They are great navigators in human history. According to statistics, 22 astronauts have stayed in space forever.
We must know that any plan is risky, and although we want to uncover the mystery of the universe as soon as possible, we must know that there are many variables in the process. Astronauts have very strict requirements during the selection process, and after a series of training before entering the space exploration environment, sometimes accidents are unavoidable. Although exercises have been repeated and carried out under the premise of ensuring the safety of astronauts, there are still some people who have unfortunately become victims of this task. At this time, many people are very concerned about this question. Can the bodies of these astronauts return to Earth? Or what kind of ending will they have?
First of all, we all know that if it is on the earth, human remains may be decomposed by various microorganisms and finally merged into the soil. But you must know that the environment in space is very special. Because it is a vacuum environment and the temperature is also very extreme, it is actually relatively more convenient to preserve the remains. It is very likely that the remains of these astronauts may be difficult to decompose. . However, some scientists said that there may be some anaerobic bacteria living in space. If there are, the remains of these astronauts may be decomposed, but the decomposition rate is very slow.
However, some researchers believe that the air pressure and temperature in space will also affect the remains, especially in the vicinity of different earth and celestial bodies, and its environment is different. If it is said that different celestial bodies may be exposed to different temperatures, the remains may also be damaged. In fact, you must know that these astronauts are all wearing spacesuits, which can store part of the water and oxygen, so they may be undergoing a slow decay process, which means that their remains may not be so complete.
These great astronauts, their dedication is worthy of our admiration, and it is absolutely impossible for us to give up like this. Some scientists said that relevant agencies have tried to launch a plan to transport the remains of these astronauts back to Earth, so that they can better deal with the funeral. In addition, they may also invest a certain amount of energy to maintain the integrity of their remains, and have made such a great contribution to mankind. They must not be ignored in this way, regardless of whether they can be transported back to the earth smoothly or not. Their spirit will always be remembered in our hearts.
For every astronaut, not only has to undergo rigorous and hard training, but also face such great pressure and risks. Therefore, we should always keep in mind the outstanding achievements made by these astronauts. contribution. At the same time, we also look forward to one day in the future with technological development that can avoid these risks for them and make exploring the universe safer.
