Why are scientists afraid to bring Martian soil back to Earth? What will the consequences be?

Since the 1860s, with the continuous development of people's aerospace technology, people have also successfully left the earth, taking the first step to explore space, which is also a very important step.

In fact, for humans at that time, the ability to explore and study space was also very limited, and people's preferred target was the moon that was closest to the earth.

And in 1969, human beings also successfully landed on the moon and stepped out of the earth for the first time, taking a very important step into space.

After the astronauts landed on the moon, they also carried out related explorations on the lunar surface, and brought some soil and rocks on the moon back to Earth for research.

And the whole process is like a scientist's study of the earth, by observing soil and rocks.

Even though many things can be erased over time, the traces hidden in the rock will never be erased, and it can also show the past and experience of the planet.

Through the study of the soil and rocks on the moon, scientists have also discovered many mysteries about the moon, which has also given humans a deeper understanding of the moon.

Later, people thought that there were not many things on the moon worthy of more human and material resources for human research, and the moon was only a satellite of the earth, and it was better to spend a lot of time and human and material resources on the moon. A more in-depth study of his planet in the solar system, so humans set their sights on Venus and Mars.

For Earth, it is farther away than Mars, so it is very difficult for humans to have a deeper understanding of Venus with the current level of human science and technology.

It's not just because of the distance that there is a certain connection to the environment on Venus.

The climate on Venus is relatively harsh, and it can even be called a purgatory planet. The average temperature of Venus can reach 460 ° C, the atmospheric pressure is much stronger than that of Earth, and it often rains acid rain.

When scientists recognized these facts, scientists also began to shift their targets. They thought that it might be easier to survey Mars than Venus.

If we launch a probe from Earth to Mars, it will take about half a year or even a year.

In order to know more about Mars, in recent years, many countries have begun to launch multiple probes to Mars. According to the news returned by the probes, people have also gained some new understanding of Mars.

But if humans want to know more about Mars, it is far from being able to rely on probes, so it is necessary to survey the soil and rocks on Mars.

Seeing this, many people will think that if the soil or rocks on Mars can be brought back for scientists to study, then people can learn more about Mars, and these tasks are much easier than the work of the probe on Mars.

Scientists have been afraid to bring soil or rocks from Mars back to Earth, because it is likely to have some relatively serious consequences after they are brought back. Why?

On the one hand, because our current technology is not yet mature, it is also difficult to bring back soil or rocks from such harsh conditions as Mars.

But the most fundamental reason is because scientists believe that there are still many uncertainties about the soil and rocks on Mars, and they don’t know much about the existence of other microorganisms. If they are brought back to Earth, it will be very Some very bad consequences can occur and are beyond your control.

The main reason why scientists dare not bring soil and rocks from Mars back to Earth is because they are afraid that there will be many microorganisms in these soils and rocks. damage, so so far I have not dared to ask them to bring it back.

It is believed that with the continuous development of science and technology, people's understanding of Mars will also become more and more. One day, the soil and rocks on Mars can be brought back to Earth, so that people can have a deeper understanding of Mars.
