Why didn’t the probe bring Martian soil back to earth for research? It turns out that the consequences are so serious

This paper takes part in the series essay competition of “great science” of Recordunkown.

Hundreds of years ago, mankind opened the industrial age and formally entered the road of scientific and technological development. With the help of science and technology, human civilization has achieved leaps and bounds, soon realized the dream of flying to the sky, walked out of the earth and began to explore the universe.

And the first planet for human exploration is the moon, which is a satellite of the earth, very close to us. Moreover, the position of the moon in the hearts of mankind since ancient times is extraordinary, people also want to understand, what is the scene on the moon? Is there an alien base on the moon? Are there more mysteries?

In 1969, Apollo 11 of the United States finally realized the first human landing on the moon, and the significance of this landing on the moon for mankind is extraordinary. At that time, humans also saw the surface of the moon for the first time from a close distance, which made people lose a lot. The moon is not as beautiful as we think. In fact, it is a very desolate planet. In addition to countless craters, there are craters.

After completing the lunar exploration mission, the astronauts also returned to the earth and brought back some samples of lunar soil and rock. I believe many friends know that the best way to study the history of a planet is to study the soil and rocks on the planet. Although merciless years can erase most of the information on the surface, it is difficult to erase the information in soil and rock.

It is through the research and exploration of various rocks on the earth that scientists can give us a more comprehensive understanding of the history of the earth, especially for the life history of the earth, through various fossils. In the same way, if we want to understand the history of the moon, it is necessary to study its soil and rocks.

As a result, scientists learned more about the moon’s secrets, such as the origin of the moon, from soil and rock samples they brought back from the moon. The information of lunar rocks tells us that the moon is probably separated from the earth, that is, in the early days of the earth, a Mars sized planet hit the earth, and the separated material formed the moon.

After the manned landing on the moon 50 years ago, people’s attention to the moon has been decreasing. Because we know a lot about the moon through its rocks and soil, and the moon is just a satellite. At this time, scientists focused on Mars, the earth’s neighbor.

Mars is also a planet in the habitable zone. It is similar to the earth in many ways. Scientists regard Mars as the second habitable star for human beings to explore. In order to explore Mars, scientists have launched more than 40 probes to Mars, including orbital probe and landing probe. China will launch Mars probe this year to start the Mars exploration mission.

Through the continuous exploration and study of Mars by these probes, we also have a more comprehensive understanding of Mars. But more than half a century has passed, there is a problem that has been bothering many friends, that is, why does the probe not bring Mars soil and rocks back to earth for research? Scientists have a very deep understanding of the history of the moon through its soil and rocks.

If we can study and explore the Martian soil and rocks, maybe we can have a deeper understanding of Mars, and even find the secret of the great changes in the history of Mars. From the current probe’s discovery on Mars, scientists believe that long ago Mars was not desolate, but a green planet very similar to the earth.

In ancient times, Mars may have a magnetic field, a thick atmosphere, a lot of liquid water, and life. But then the ecology of Mars changed dramatically, making it desolate step by step. What is the cause of the upheaval on Mars? To solve this mystery, it may be difficult to understand by exploring the surface of Mars. Only by studying the soil and rocks of Mars can we find the answer.

Scientists are also very eager to study the Martian soil and rocks, but we can not bring the Martian soil back to the earth, because the consequences of doing so may be very serious and may bring crisis to the earth and human beings. Why? In fact, the root cause is related to microorganisms. At the beginning of this year, COVID-19 now believes that everyone knows that this is a war between humans and viruses.

Virus is a kind of microorganism, and microorganism is life that human naked eye can’t see. Although they are simple life, the threat to human is huge. Since ancient times, the loss of virus disaster to human beings is immeasurable. Even now, with the development of science and technology, we don’t know much about viruses. They are still our biggest threat.

Therefore, what human beings are most eager to see is life, and what they are most afraid to see is life, especially invisible microorganisms. The birth of life needs to meet a basic condition that is to have a certain ecosystem, and to form a certain ecosystem, the planet must first have an atmosphere.

We all know that there is no atmosphere on the moon, so there is no ecosystem on the surface of the moon, without which life is unlikely to be born. Even the simplest microorganisms are difficult to form on the moon. It is in this way that scientists dare to bring the soil and rocks on the surface of the moon back to earth for research and exploration.

But Mars is totally different from the moon, it has a thin atmosphere, and we all know that Mars has sandstorms, so Mars has an ecosystem. According to decades of exploration on Mars, scientists not only found water on Mars, but also found organic matter such as methane. This shows that Mars may not have complex organisms, but simple life like microorganisms may exist.

If there are microbes on Mars, they will probably be in the soil. Once we bring them back to earth, we may bring microbial life from other planets. We should know that the life formed in different planetary environments may be very different. Once two completely different forms of life land on each other’s planets, it may pollute the ecological environment, or even bring catastrophic biochemical crisis.

Because we don’t know about life on Mars at all, we don’t know if there is life on Mars, and if so, what kind of life is it? Will it pose a threat to the earth’s ecology and human beings? All this is unknown. We can’t bring Mars back to earth until we have a thorough understanding of the mystery of Martian life. This is a kind of protection for the earth’s ecology and also for human beings.

In the future, if scientists want to study Martian soil, they may also need to build a foundation on Mars or conduct research in space. Only by making sure that the Martian soil is not a threat to the earth and human beings, can we bring the things on Mars back to earth for research.
