If humans can run into space, what do they need to prepare?

Your question is too future. If we take people's mentality as an example, traveling in space is completely lonely and isolated. First of all, we should be prepared psychologically and be prepared not to come back. The second is physically, astronauts are carefully selected and must ensure good health. Finally, you should also be prepared to eat. The answer can only be this, because I have never been to space.

In the future, our generation has a great possibility to travel in space, so what should we prepare?

The first is a healthy body. If you are not healthy, you will be in danger of going to Tibet and space, not to mention. The second is the mentality of facing everything, darkness, silence, boredom, loneliness and even death, and then maybe you will never return to the earth. Besides, we should take everything we need, such as oxygen, fresh water and antibiotics. , and communication. If you can't keep in touch with the ground, there is no chance of being rescued.

With the steady development of space technology, human beings have begun to slowly walk out of the earth and move towards deep space. Although Venus is the most dominant in terms of distance, its harsh environment makes colonization impossible. As the second closest planet to the earth, Mars is much better than Venus, although its environment is equally bad, so it will become the second hometown of human civilization.

In addition to the low gravity environment of Mars, oxygen and water are necessary to colonize Mars. Now, scientists plan to melt the poles of Mars with a nuclear bomb or a huge solar reflector. If successful, Mars will once again have oceans and lakes, and its colonists will have oxygen with water.

When the basic survival problem is solved, it will be the focus of work to use its resources to make Mars a planet suitable for human habitation and try to avoid repeating the mistakes of the earth.

The atmosphere of Mars is very thin, only about 1% of that of the earth. This kind of atmosphere has a very poor ability to bind heat, which leads to the very cold surface of Mars, with an average of only about MINUS 60 degrees, and the temperature difference between day and night is very large. The highest temperature on Mars can reach more than 30 degrees, and the lowest temperature is minus 140 degrees. Therefore, the primary task of transforming Mars is to increase the concentration of the atmosphere.
