When human beings walked out of the earth and saw the vast universe, they were full of curiosity about the existence of extraterrestrial life. From the perspective of the universe, the probability of the existence of extraterrestrial life is basically 100%, but before humans can really find extraterrestrial life, the topic of extraterrestrial life is just a variety of speculations.
Due to technological limitations, humans have not yet been able to go out of the solar system to explore other galaxies, and the focus of finding extraterrestrial life can only be on the solar system. Someone might say, don’t scientists search for alien civilizations by transmitting wireless signals and searching for cosmic signals? In fact, with these two search methods, the probability of success is basically zero.
Even if there are wireless signals sent by advanced civilizations in the universe, due to the different civilizations and the huge gap in technological strength, with the existing technological strength of mankind, even if we are lucky enough to receive such civilization signals, we will not be able to crack and understand. The content of the signal.
Therefore, the focus of scientists searching for extraterrestrial life is still on the solar system, and the most likely existence of extraterrestrial life in the solar system is Mars. Mars is the neighbor of the earth, and it is also a planet in the habitable zone. Theoretically speaking, the possibility of Mars existence is very high.
Since humans left the earth in the last century, the mission of exploring Mars has begun. Although it is a neighbor of the earth, the exploration we can achieve is limited to unmanned probes. For nearly half a century, scientists have launched dozens of probes to Mars, including orbital probes and landing probes.
Through the continuous efforts of these probes, we now have a lot of knowledge about Mars. We know that the surface of Mars is very desolate, and there is still water in the polar regions. In addition, the probe also discovered ancient riverbeds on the surface of Mars and discovered organic matter. All signs indicate that Mars long ago was not as desolate as it is now, but a beautiful planet with a high probability of life.
Later, an unknown disaster occurred on Mars and gradually became the way it is now. This discovery made scientists very excited. This means that Mars used to be a beautiful ecological planet, and there was a high probability of life. Although it has become a desolate planet, there may still be some tenacious life.
Among the many Mars probes, the Curiosity rover that has contributed the most to mankind should be the Curiosity rover, which was launched in 2011 and landed on the surface of Mars in August 2012, starting an 8-year exploration of Mars. Chest is also the world’s first Mars rover powered by nuclear power. It has strong power and very powerful functions.
An important mission of the Curiosity rover is to search for possible signs of life on Mars. In the process of continuous exploration, Curiosity sends back a large number of Mars photos to the earth, some of which have attracted the attention of scientists, and even some photos. Suspected life phenomenon also appeared on it. For example, some time ago, there was a photo of Mars “human bones” that sparked heated discussion.
From this photo, we can clearly see that there is something very much like a “human bone”, then is this true? NASA scientists later answered this question. This photo is real, and what is suspected to be “human bone” on it is also real, but it is not a real human bone, but a natural product carved by the erosion of wind or water.
In fact, among the large number of photos sent back by Curiosity, there are still many photos of suspected living matter like this. For example, in 2019, entomologists also announced the existence of insects on Mars, and they also announced it at the American Science Conference. Finally, NASA publicly stated that it was a fossil, as well as Martian Bigfoot, Martian Spoon, Martian Warrior, Martian Mushroom, etc.
Judging from the photos, these things are very similar to the products of life or civilization, but in the real situation they are the result of natural action. Even on the earth, we can see many god-like stones. They are the products of nature’s extraordinary craftsmanship, and Mars often has storms. It is not surprising that some god-like stones appear in the natural environment.
Although Curiosity has not discovered real life on Mars, as the exploration continues, scientists have higher and higher expectations for the probability of life on Mars. Scientists do not expect to be able to discover some complex life on Mars. According to the Martian environment, the probability of the birth of complex life is basically zero.
Although it is unlikely that advanced life will appear, the probability of the existence of microorganisms is still very high, and they may exist in the soil of Mars. Curiosity does not have more powerful detection tools, and has no ability to detect the existence of life in Martian soil. Scientists put their hope on NASA’s new-generation Perseverance Mars rover.
The “Perseverance” Mars rover is equipped with a high-power camera and an ultraviolet laser. The exploration of life on Mars is mainly through the determination of soil chemistry and mineral composition, so as to achieve the possibility of searching for life.
In addition, my country’s Tianwen-1 Mars Rover has been out for more than two months, and it will not be long before it will board Mars for various explorations, including the detection and search for life. With the continuous advancement of human science and technology, the capabilities of the probes are constantly improving. With their help, the mission of searching for life on Mars believes that good news will arrive soon.
Whether there is life on Mars is of great significance to human beings. From the perspective of detecting extraterrestrial life, if life is discovered on Mars, then the question about whether there is extraterrestrial life will be answered. From the perspective of future transformation and migration to Mars, if there is life on Mars, then more aspects need to be considered for the transformation and survival of Mars.
You should know that life on different planets may have huge differences in genes and other aspects due to the different living environments. Even Martian microbes have a huge challenge to the ecological environment of the earth and the impact of life on earth. If there is no life on Mars, then we can safely and boldly carry out various transformations on Mars. In the future, there will be fewer obstacles to the goal of human migration to Mars.
But if there is life on Mars, then we need to consider the various threats they may pose to humans. Of course, if we want to really search for more information on Mars, in the future we will still need to send astronauts to land for detailed exploration, and even establish a human base on Mars. As long as we can carry people to Mars, it will be easy to understand incidents like the suspected “human bones” discovered by Curiosity earlier.
Exploring life on Mars is only one direction for humans to search for life outside the earth. In fact, in addition to Mars, some moons of Jupiter and Saturn are also very likely to have life. It’s just that it is much more difficult to detect those satellites than to detect Mars. It can be seen that technology is the most important thing. As long as our scientific and technological strength can be greatly improved, and we can quickly travel all corners of the solar system, searching for possible extraterrestrial life in the solar system will become very simple.
