When the "Sailor 4" Mars rover successfully flew over Mars and returned photos of the surface of Mars, we saw for the first time the extremely desolate and arid scene on the surface of Mars. These images made many scientists dream. All shattered. Because before the arrival of the probe, many of us thought that Mars might have the same vibrant scene as the earth. After all, Mars and the earth have many similarities, and they are both in the habitable zone of the solar system.
Mars colonization in 2050?
Although the Mars we see is extremely desolate and arid, it does not affect human enthusiasm for exploring Mars. In the past few decades, humans have launched many Mars probes to reach Mars, and now there are even some manned landings. Mars, the dream of emigrating to Mars.
SpaceX’s Musk has repeatedly stated that he is confident of sending 1 million people to Mars by 2050 and building a 1 million Martian city on Mars. From time Look at it, it will be in the next 30 years. It is envisaged that SpaceX will build 1,000 interstellar spacecraft , these interstellar spacecraft can carry up to 100 passengers at a time, and plan to launch 3 interstellar spacecraft every day to finally realize the Martian migration . For most of my friends, they may think that the idea of emigrating to Mars and building cities on Mars is too advanced. After all, it is still relatively difficult for humans to explore the moon 380,000 kilometers away, let alone build one on Mars, which is more than 55 million kilometers away. Martian city.
Although it looks a little weird,However, many researchers believe that it is possible to migrate to Mars in the next 30 years. Professor Serkan Saydam of the University of New South Wales, Sydney , said after seeing the NASA Perseverance Span1span rover landing on Mars, robot mining that provides sufficient water and energy will become the key to migration to Mars in the next 30 years, as long as it can To make the process of autonomous mining more commercial in vain, it is still feasible to realize Martian migration in 2050.
Before emigrating to Mars, we still have many technical problems to be solved, one of which is the need to develop water resources on Mars. Because the distance between the earth and Mars is very long, transporting water resources from the earth to Mars is not feasible in many aspects such as technology and cost. Scientists have discovered that water still exists on Mars, and the water content of Mars is still considerable. If we can develop water resources on Mars, we can get oxygen and hydrogen from water resources.
Mars or unknown creatures?
Although there are already plans for manned landing and immigration to Mars, these plans may be too risky. Because our current knowledge of Mars is still very small, in the next few decades, even if there are more advanced probes to explore Mars, there will still be no more adequate knowledge of Mars. Inadequate knowledge of Mars means that potential threats cannot be effectively detected.
For example, there used to be and liquid water on Mars in ancient times, and the temperature is more suitable. In such a more habitable environment, there may have been living things on Mars, even though Mars has changed. It was extremely dry, and those potentially ancient creatures might still survive to this day. Because water ice material still exists on Mars,These water ice substances will melt seasonally as the temperature rises, which can nourish these potential organisms.
We also shared an experimental study before. Scientists put some microorganisms in some culture solution for cultivation, and then dry the culture solution, and the microorganisms living in the culture solution are also dried. Immediately afterwards, scientists once again added moisture to these dried microorganisms, and these microorganisms once again restored their vitality. This study shows that if there are prehistoric microorganisms on Mars, even if they may be dried out, they may still survive again when they get moisture.
At present, we humans have not yet found any signs of Martian microbes, so we don't know whether these microbes still exist on Mars, let alone the characteristics of potential microbes on Mars. Under such circumstances, if humans rush to land on Mars and emigrate to Mars, they may face the threat of these potential microorganisms, and no one knows what threats these potential microorganisms will bring to us humans. Therefore, before immigrating to Mars in the future, it may be necessary to study these potential challenges and make a sound plan.
