Curiosity’s self photography, let us see the real surface of Mars, what will it look like?

There are eight planets in the solar system, four of which are earth like planets. Except for mercury, which is close to the sun and not in the habitable zone, the other three planets are in the habitable zone. Venus, earth and Mars are the three earth like planets in the habitable zone of the solar system. If you compare them together, you can see which is more beautiful at a glance.

There is no harm without comparison. When Venus, earth and Mars are compared, we can see the beautiful and dazzling blue style of the earth. While Venus and Mars look a little desolate, showing a red appearance. In terms of mass and volume, Venus is undoubtedly the closest to the earth, so scientists also call Venus the sister planet of the earth.

It is because Venus is so similar to the earth that it is the first thing that human beings explore after walking out of the earth. But when the probe reached the orbit of Venus, we saw a purgatory world wrapped in a thick atmosphere. Venus surface environment is too bad, not only the temperature as high as 460 degrees Celsius, but also often have sulfuric acid rain.

Venus thick atmosphere and poor performance environment, hindered the further exploration of the probe. After many failed attempts, scientists had to give up the exploration of Venus and focus on Mars. The mass of Mars is only one tenth of that of the earth, much smaller than that of the earth.

Compared with the purgatory world of Venus, the surface environment of Mars is much better. With only a thin atmosphere, human probes can also go to Mars for long-term mobile exploration. However, if the probe wants to go to Mars, it is more difficult than to go to Venus, and it needs to wait for the Mars window to arrive once every 26 months before it can launch the probe.

The exploration of Mars started 60 years ago, but some of the first probes failed. It was not until 1964 that mariner 4 successfully flew close to Mars. This is also the first time that we have taken close-up photos of Mars. Through these photos, we can see a desolate world, and there is no Martian life that some people think exists.

With the continuous progress of human science and technology, the Mars probe is also constantly improved, more and more advanced. At the Martian time window in 2011, scientists launched the curiosity Mars probe powered by nuclear power, which integrates the most powerful space technology of human beings at that time. No one thought that curiosity made great contributions to human understanding of Mars in the later exploration years.

After reaching Mars, curiosity began its mobile exploration, and took a lot of Mars photos in the process of moving. These photos are different from those taken by previous explorers. In the past, the photos of the surface of Mars were rather vague, but many of the photos of curiosity were very clear, especially some self photos, which showed us the real surface of Mars.

In a self portrait of Mars, curiosity drilled three small holes in the surface of Mars and took several self portraits by standing beside the three holes. Some friends may have seen the photos of the distribution, but they didn’t find the three small holes. That’s because these small holes are too small and they don’t see clearly from different angles.

In another close-up photo, we can clearly see that there are three small holes on the left side of the curiosity Rover. Scientists named them groken, Mary Anning and Mary Anning 3. Why did curiosity drill these holes? The purpose is to study some details of the ancient environment of Mars.

With curiosity taking all kinds of very clear photos of the surface of Mars, scientists realized through these photos that although Mars is very desolate now, it looks like the Gobi desert and desert area of the earth, all kinds of signs show that Mars in ancient times may not be desolate, but a beautiful ecological planet, with a large amount of liquid water on the surface, or even not Excluding ancient Mars, it is also a planet of life.

These major discoveries on the surface of Mars are very important for human beings. One of the important purposes of human exploration of Mars is to expect it to become a second home for human beings. Although the earth is our home planet, but the rapid development of industry makes the earth’s ecological environment deteriorating, and the earth’s population is also growing.

Whether from the perspective of ecological environment or population, the future Earth may not be suitable for human survival. We need to find a new home ahead of time. Even if human beings make efforts to improve the ecological environment of the earth in the future, it is difficult to control the huge growth of population, and the earth’s bearing capacity is limited.

When the global population exceeds 10 billion, the pressure on the ecological environment will be very great. At that time, we need to divert part of the earth’s population to other planets. Mars is undoubtedly a better choice, and the current environment of Mars is not suitable for human survival, so it needs to carry out various modifications.

To transform Mars, we need to know more about its history. Now scientists have found that ancient Mars may have been an ecological planet, and there was a lot of liquid water on its surface, which is undoubtedly good news. This shows that Mars has an excellent ecological environment, especially water resources. Current observations show that there is still a lot of water at the poles of Mars, and even some liquid water may be stored under the surface of Mars.

Water is not only the source of life, but also an important material needed to transform the environment. With water, it will be much easier to transform the Martian environment and make it the second home of mankind in a shorter time. The more we know about Mars, the more hope it will become the second home of mankind. At present, scientists have more and more hope for the success of Mars transformation.

With the continuous good news coming from Mars, countries all over the world are unable to sit still and have launched Mars exploration programs one after another. In this year’s Martian time window, China’s tianwen-1, UAE’s hope, and the United States’ Willpower were all launched to Mars for exploration.

We can foresee that in the next time window, more Mars probes will be launched to Mars, and in the near future, manned landing on Mars to establish a preliminary Mars base will not be too far away from us. With the Mars base, we will be able to better explore Mars, and initially start to transform Mars.

As long as there is a lot of vegetation on Mars and oxygen in the atmosphere, there will be no problem for human survival. Of course, the atmosphere of Mars is relatively thin, the solar radiation and cosmic radiation are much more serious than those on earth, and the human fragile body’s resistance to these radiation is also relatively weak. Therefore, people who will migrate to Mars in the future need to carry out some genetic modification to have strong radiation resistance.

Anyway, Mars has been reserved by human beings, it will be the second home of human beings, and with the help of science and technology, it is not difficult to realize it. In the future solar system, the pace of human beings is no longer limited to the earth. At that time, there will be another branch of human beings, Martians. Of course, Venus may also become a new home for human beings. To some extent, it is more suitable for human survival than Mars. We only need to solve the high carbon dioxide content in the atmosphere.
