Why did you immigrate to the Gobi Desert?

In our solar system, there are many planets rich in water resources. For example, the water content of Europa may even exceed that of the earth, and even Pluto at the "edge" of the solar system has been found to have a liquid ocean. Mars, which is more than 55 million kilometers away from the earth and 400 million kilometers away from the earth, looks desolate and arid, but many probes have also found that Mars also contains a lot of water resources, and its water content may even meet the needs of long-term Martian immigrants in the future. Compared with Europa, Mars is relatively close to the earth, and there are many similarities between the two, so many people think that Mars is our potential "second home". As a potential "second home", what is Mars like?

Perseverance is the fifth rover launched by the United States and the second rover equipped with nuclear batteries in the world. Compared with the previous rover launched by the United States, it is more persevering. Its mission is not only to conduct scientific research on the surface of Mars, but also to collect samples on the surface of Mars and seal them so that NASA and ESA can launch new Mars probes to bring them back to Earth in the future. In other words, we are making some preparations for sampling Mars and returning to Earth.

In addition to scientific research and sample collection, the expensive rover "Perseverance" keeps taking photos of Mars. Before that, we have seen the photos of Mars sent back by the rover Perseverance, some of which are self-portraits of the rover Perseverance, and some are panoramic photos. Now NASA has shared some pictures sent back by the Mars probe Perseverance, showing the scene of Mars in front of us.

From the shared pictures, we can see the scene of Mars intuitively. After all, this is a photo taken by the rover on the surface of Mars. There is no doubt that these photos are not obviously different from those seen by rovers such as Curiosity, Spirit and Opportunity. There is sand everywhere, and there are a lot of rocks of various shapes. Some rocks are partly buried under the Martian dust, and some rocks are partly exposed on the ground. Such a scene is very similar to the Gobi desert area of the earth.

During this time, we also saw the topic about why the rover can't take shape quickly. The objective factors such as the energy of the rover limit the speed of the rover, so the rover cannot be rapidly formed. In addition, these photos also show us that there is really no road in the world. Assuming that the speed of the rover is unlimited, we dare not drive too fast in this environment, because it is easy to hit these rocks or get stuck in the sand.

On our planet, most living things, including human beings, can't survive in the desolate environment of the Gobi Desert for a long time. I believe many friends are reluctant to emigrate to desert and Gobi desert. The environment of Mars looks like the Gobi desert of the earth, which is not suitable for our human survival, but many people have the idea of immigrating to Mars.

For example, Mr. Musk of SPaceX, his dream is to build a Mars city and send 1 10,000 people to Mars by 2050. The UAE also has plans to build Mars City in 265,438+065,438+07. From the perspective of scientific and technological development, it is still possible for human beings to step out of the earth, into the depths of the universe and onto the surfaces of other planets. For example, as early as 50 years ago, man had already landed on the moon. However, it may not be realistic to immigrate to Mars in a short time.

At present, only a few countries have mastered the technology of flying around Mars, landing on Mars and patrolling Mars. The next step is to collect samples from Mars and then return to Earth. Only when we have the technology to take off from the surface of Mars and return to Earth from Mars can we talk about manned landing on Mars, because we can't send astronauts to Mars without returning to Earth. Even though the technology of manned landing on Mars may appear in the near future, it is still very different from emigrating to Mars.

Compared with the probe exploring Mars and manned landing on Mars, it is more difficult to immigrate to Mars than expected. Because the environment of Mars is not suitable for human beings to live directly, one of the prerequisites for emigrating to Mars is to establish a habitat on the distant Mars (such as the underground base of Mars and the city of Mars). ), expensive and technically difficult. At present, the urgency of our emigration to Mars is not very strong, so we can not invest much money. At present, the technology can't meet the requirements and the funds can't be guaranteed, so it's not realistic to send people to Mars. However, science and technology will always improve, and the future technology of mankind will certainly be more advanced, and it will be less difficult to go to Mars. Maybe in a hundred years or thousands of years, it will be as simple for us to go to Mars as it is now for us to cross the ocean.
