Why does NASA want to simulate survival on Mars and test human nature? What exactly did they find?

The barren north slope of Hawaii's Monaloa volcano is the most inhospitable region on Earth and one of the closest to Martian surface features. On August 28, 2016, the year-long Mars was launched here. Explore simulation missions, starting with the most basic human survival and life, and validate the technical problems that may be encountered during the long journey from Earth to Mars!

It's just that in order to be able to familiarize everyone with the survival on Mars in the future, which is more conducive to the continuation of human civilization, I don't think I found anything.

Because astronauts living in a closed environment for a long time can have an unsatisfactory psychological impact, it is necessary to simulate the living environment on Earth now to assess what might happen.

There is no doubt that NASA's technology has always been ahead of us, and this time he wants to simulate survival on Mars is just to prepare materials and experience in advance for the future landing on Mars, which is not surprising.

NASA's Mars 2020 mission hopes not only to find answers to many questions about the Red Planet, but more importantly, to find extraterrestrial life. Although Mars is very barren and has a very harsh living environment, life may have existed billions of years ago. Scientists are using Mars landers and orbiting satellites to find relevant clues, and as the investigation deepens, more and more clues indicate that there is a high probability of life on Mars.

But if we finally find evidence of life on Mars, how will humanity react? In an interview with The Sunday Telegraph, NASA chief scientist Jim Green said we weren't ready.

In March next year, the European Space Agency's (ESA) Mars rover Exomars will be launched to Mars along with NASA's Mars rover Mars 2020, The Telegraph reported on Sunday. ESA's Mars rover is also known as Rosalind, which is in honor of the British chemist Rosalind Franklin.

The mission of the two Mars rovers is to search for extraterrestrial life and organic matter on the planet Huoyouxun. They will drill and sample the Martian rocks for analysis. Scientists will focus on 300 minerals in Martian rock samples that can only be produced by life.

Dr. Jim Green, NASA's chief scientist, who is involved in the research project on two Mars rovers, believes that extraterrestrial life could be discovered within months of the rover's landing on Mars.

But this "revolutionary" discovery will "open up a whole new starting point," Dr Green said, "I don't think we're ready for this outcome." "It is reported that the two Mars rovers will conduct rock sampling primarily in the ancient seabed area of Mars.

When the environment becomes extreme, life turns into rocks. Dr. Green said.

Microorganisms may be present on MarsAfter scientific research, scientists speculated that there are very likely microorganisms on Mars, and scientists compared the environment of Mars with that on Earth, and found that the environment of the Atacama Desert and Mars seem to be similar! It is precisely because of this that scientists believe that human exploration of Mars may be able to destroy the microbes of Mars! What does this mean?

It means that in the past, Mars was as wet as Earth.

Why Mars turned into a red desertIn the history of more than 4 billion years, Mars may have given birth to life like Earth, and Mars was similar to life on Earth before, but why did they only leave traces on Mars and become the red desert they are now? In the future, if human civilization has the opportunity to expand to the entire solar system and even the entire universe, Mars may become the next foothold and transit point for mankind.

Martian soil also has a lot of ice stored in itThe Phoenix rover has detected the presence of water at its landing site, and the Curiosity rover has also detected the presence of water in Martian soil through its Martian sample analysis equipment. The most important reason for the loss of Martian water resources is that Mars has gradually lost its dense atmosphere, which makes Mars unable to maintain its surface temperature and atmospheric pressure, liquid water no longer exists, and the appearance and state of the surface have gradually undergone a fundamental change, becoming a bare red planet. The research continues, and perhaps in the near future, there will be an answer.

It is said that there were traces of water in Mars.

Humans are famous for their eyes on Mars, as well as their soil air. Physical environment.

There is a great deal of research on the material and geography of Mars.

What people know about Mars is that there may be certain microorganisms on Mars.

Humans have carried out large-scale exploration of Mars and are analyzing it.

There may be microbes on Mars, and there are also studies in this area.

The sulfate may have been left over from the evaporation of ancient brine that once contained a certain life form, which evaporated during the Hesperi period in Martian history.

The main mission of Perseverance is, of course, to continue the exploration of life on Mars, but it will also carry out an unprecedented exploration - the collection of Martian sounds.

Quest for life on Mars: The most important mission of the Perseverance mission will be to search for signs of ancient microbial life on the Jezero crater in the Martian delta, which collapsed 3.5 billion years ago, and to collect and store geological samples that may contain the first evidence of extraterrestrial life, and to bring the void and its back to Earth.

According to NASA**, the Perseverance will land on February 18, 2021. During this major mission for at least one Martian year (about 687 Earth days), Perseverance will conduct a full-scale exploration of the Jezero crater, which will provide evidence for solving questions about the origin of life on Mars, including the feasibility of a Martian settlement plan at a future date.

The astrobiological mission of the rover is to search for signs of ancient microbial life in order to characterize the climate and geology of Mars and to collect reliable samples for future returns to Earth. Perseverance will also conduct research on human survival expeditions on Mars and prove its feasibility.

Collecting Martian sound samples: This is a very interesting study, as various rovers and orbiters have sent countless images of the fiery planet back to Earth, but we have never heard even the slightest sound from Mars. Perseverance is going to break this limitation, and its goal is to listen to and collect the sound of Mars by carrying two microphones.

These microphones will collect audio as it lands, as well as the ambient noise of the fiery planet and the roaring noise of the rover as it works.

Actually, it's mainly because of the relationship between the position of Mars and the Earth. As we all know, Mars is very far from the Earth, almost hundreds of times from the Earth to the Moon, and even the most advanced human probe needs about seven or eight months to fly from the Earth to Mars. And because both the Earth and Mars orbit the Sun, and their relative positions are constantly changing, it is easy to know that when they are closest, that is, when the Sun, Earth and Mars are in the same straight line, the distance traveled by the probe will be much smaller, and it will be more "economical" to launch a probe.

This is called the rendezvous cycle in astronomy.

I think so. Because this project has been researched for a long time, a lot of money and effort has been spent.

I think it may be possible to find that because Mars is the most similar to the planetary beam of the planet that can be determined on the basis of our existing science, there is still a possibility of life.

No, because I don't think technology has developed to that point yet, and it may be a few years later.

The first is the issue of fuel for spacecraft, because many countries currently use liquid fuel for rockets and spacecraft, so that the farthest destination for mankind is the moon. NASA scientists say that conventional liquid fuels are clearly not sufficient for human requirements because they require a lot of space and a large total mass, which will have to be overcome if the spacecraft wants to fly longer distances.

NASA's proposal to replace traditional energy with nuclear energy sounds constructive because nuclear energy provides more energy than traditional energy, and it does not take up a lot of space. There are also concerns about the use of nuclear energy in spacecraft, because in the event of a nuclear accident, life on board will generally not survive. But the person in charge said that the nuclear technology they plan to adopt is miniature nuclear fission, which is more controllable than large nuclear reactions on Earth.

At the same time, the person in charge also listed the many advantages of using nuclear energy, such as the ability to produce a large amount of energy with only less fuel, and the space saved on the spacecraft can also be used to place other devices, such as a small power system, knowing that electricity is indispensable for human beings, even if humans want to immigrate to Mars, they need to use a lot of electricity. In addition to the fuel issue, NASA has also said that they will have other technologies to convert the resources of the universe into the resources needed for human survival.

If humans do land on Mars in the future, or even build a home on Mars, then a closed ecosystem must first be built. This closed ecosystem is isolated from the natural environment of Mars, but there are cycles throughout the system. In this way, future humans will be able to work and produce on Mars, so as to achieve self-sufficiency in food and resources.

The third and most important issue is the reproduction of humans on Mars.

With the advancement of technology, I think it should be possible for humans to land on Mars, and the most critical issue now is to solve the power of the spacecraft, and how the astronauts will survive this long flight.

When the fake is true, the truth is also false, and one day it will be known.

That's for sure, as long as the technology is good enough, maybe it really can.

Human beings are still a first-class civilization, and it is believed that they will soon land on Mars.

Impossible, the current stage is not enough.

Absolutely, believe in yourself.

That's for sure, as long as the technology is good enough.

I think it can be, but for a long time.

Let's look quietly, it is estimated that it is far away.

Humans may indeed one day land on Mars.

Can humans immigrate to Mars?

Will humans be able to inhabit Mars?
