Immigrants can't come back

Since ancient times, people have never stopped exploring the universe. After all, the resources on the earth are limited. As human beings, we have to think about our future life. A long time ago, people showed great interest in exploring the universe, from Zhang Heng's invention of the armillary sphere and seismograph to the birth of the school of covering the sky, announcing the night and the armillary sphere, all of which were closely related to the universe. The most advanced country in this field is the United States. Although the United States is only a country with a history of hundreds of years, its exploration of the universe has always been at the forefront of the world, and no country can match it.

In addition to searching for resources, there is another important reason for human beings to explore outer space, and that is the problem of human survival. In modern times, due to the change of environment, some scientists found that the earth is probably not suitable for human survival in the future, so countries began to think of ways and finally made plans for Martian immigrants to live. This plan was put forward by elon musk on 20 15. However, due to the limited modern technology, it is faced with the situation that people can't send it back. In other words, at present, people can only be sent to Mars, not sent back. Faced with such a situation, many people think it is not feasible.

As for why it's Mars, it's actually because Mars is the closest planet to the earth except Venus. Although the natural conditions there are very bad, compared with other planets, it is still possible to be suitable for living. After all, scientists have discovered many traces of water flow through exploration. You know, human beings can't live without water resources, and now traces of water flow have been found on Mars, indicating that there are rivers on Mars, that is, water resources. But it is worth noting that this plan has not been recognized by the outside world.

However, it is worth noting that an American girl named Ai Lisha took a keen interest in this project. It is understood that she actively participated in the organization of astronomy enthusiasts when she was very young, and has been updating the dynamics of her desire to board Mars on social platforms. With the passage of time, she also entered the age of 18. Seeing that she was so obsessed with Mars, the US space agency chose her to carry out this plan. If her landing on Mars is successful, then Ai Lisha will probably become the first person to enter Mars!

When the outside world learned the news, everyone was surprised, but for her, it was her dream. It is reported that in order to ensure that he can reach Mars safely, Ai Lisha is currently receiving intensive training from NASA. In fact, Ai Lisha and ordinary people are very aware of the consequences of this. If it goes well, it will make a great contribution to the country, but if it fails, it will be a terrible consequence for Ai Lisha, that is, death. The United States also took this into consideration, so it gave the choice to Ai Lisha.
