Can humans survive on Mars? Why?

Not at the moment.

But NASA, the European Space Agency and the Japan Space Center have teamed up to unveil an ambitious plan to rebuild Mars. (This plan will be realized over the next 200 years.) Pioneer period (2015-2031) Warm period (2030-2080) The biggest challenge is to make Mars gradually warmer.

One way to do this is to build a number of chemical plants on Mars. These plants are powered by small nuclear reactors, which then produce gases that contribute to the greenhouse effect, such as alum hexafluoride. These gases are like a carpet on the surface of Mars, so that all the heat on the surface of Mars is not dissipated into space.

As the temperature on the surface of Mars gradually increases, the atmosphere of Mars becomes thicker and thicker. Consolidation period (2080-2115) When the temperature on Mars rises to -25 degrees Celsius, some bryophytes begin to grow in slightly warmer areas of the Martian surface. When the temperature rises to -15 degrees Celsius, the amount of carbon dioxide, nitrogen, and water pumped out of the Martian crust all begin to increase massively.

The atmosphere on Mars continues to thicken, white clouds begin to float over Mars, and the color of the sky changes from pink to blue. Liquid water began to collect in the deep canals that Mars had before. At this point, the atmosphere on Mars is thick enough to transmit sound waves.

Recovery period (2115 2150) When the atmosphere on Mars finally stabilized and the average temperature rose to 0 degrees Celsius, living conditions on Mars improved greatly, and it was possible to settle on Earth. (Since the gravitational pull of Mars is only about 1 3 times that of Earth, Mars will also become a launch platform for space expeditions and a base for human travel to other planets.) ）

At least for now, the conditions for survival on Mars are not yet mature, but the future is not ruled out. Anything is possible in the future. At present, water and other resources necessary for human life have not been discovered, and many of them have not yet been discovered.

You can go, n years ago, human beings fantasized about going to the moon, but someone went, and now, people want to go to Mars again, and they may go in n years!

Can humans survive on Mars, it only needs to change these points.

So far, Mars is uninhabitable for the following reasons:

1. The Martian atmosphere does not have enough oxygen concentration for humans to survive.

Second, there is not a large amount of liquid water on Mars that can be used by humans.

3. The climate and environment of Mars are not suitable for human production activities.

But Mars is the planet most likely to be inhabited by humans besides Earth:

1. Mars and the Earth are close to the Sun.

2. Mars is similar in size to Earth.

3. Mars has an atmosphere similar to that of Earth, and although oxygen is scarce, it can be modified to achieve the same amount. Fourth, there is solid water and even liquid water on the poles of Mars.

Fifth, there are no highly intelligent creatures on Mars, and there are no competitors for human beings. After modification, Mars has the potential to become a planet inhabited by humans.

In the long future, humans will be able to survive on Mars!

Mars is not suitable for human life, because to survive on Mars, the following three problems must be solved, which are the problem of gravity, the problem of atmosphere, and the problem of oxygen.

So far, in addition to human beings living on the earth, many scientists are still exploring whether extraterrestrial planets are suitable for human beings to live, so far although some scientists have fantasized about immigrating on Mars, but various conditions do not allow human beings to survive on it, even if some terrestrial planets have been discovered, but if you want to rely on it, it may take hundreds of light years or even more.

Introduction to Mars.

Mars is the fourth planet in the solar system from the inside to the outside, belonging to the terrestrial planet, with a diameter of about half the diameter of the Earth, and it takes twice as long to rotate around the axis of rotation and the rotation period of the same approximate revolution. In the West, it is called Mars, the god of war, and in China, it is called the Luminous Star, because it shines like fire, and its position and brightness often change.

Its orange-red appearance is due to the fact that the surface of the earth is covered in hematite (iron oxide), which is prefixed with the English word areo- or Mars, which was once considered the most likely planet in the solar system to host extraterrestrial life.

If humans want to survive on Mars, they must probably produce supplies on Mars, and cannot expect to be transported from Earth. Mars has resources to exploit, but some modifications to the Martian environment are currently just pipe dreams.

Mars has a small mass and a weak magnetic field, so it is difficult for Mars to maintain its atmosphere, and it seems a bit unrealistic to modify the Martian atmospheric environment, and the best way is to modify it within a certain range. Because of the relationship between the atmosphere and the magnetic field, the radiation on the surface of Mars may be stronger, and the best way is to build a huge facility on Mars that is transparent at the top of the underground and semi-subterranean surface, which only needs to maintain the atmospheric pressure that humans can move and fill with artificial air to meet the survival needs of people, plants and animals.

One of the benefits of Mars is the presence of water. Water is necessary for any living thing on earth, as long as there is water, plants do not need soil, and they can produce food by preparing nutrient solutions and cultivating them without soil. Others will probably need to be adapted to slowly, such as the low gravity of Mars and the air pressure in the facility that is slightly less than Earth's atmospheric pressure.

Because the atmospheric pressure of Mars is too low, the boiling point of water is only five degrees Celsius, and if the human body is directly exposed to the surface of Mars, the blood in the human body will soon boil, the water will evaporate in the boiling, and the human body will become a mummy. The maximum temperature of Mars is more than 20 degrees, and the minimum temperature is more than 140 degrees below zero, because the atmosphere is thin and the radiation is strong, if it is directly exposed to the surface of Mars, human beings cannot survive.

If we humans want to settle on Mars, the best solution is to modify the natural environment on Mars. In the imagination of scientists, the greenhouse gas octafluoromethane (C3F8) is the best medicine to transform the Martian atmosphere, the potential of this gas is 24,000 times that of carbon dioxide, only one million of the Martian atmosphere, enough to raise the temperature of Mars by more than 30 degrees, and then enough to melt the ice under the Martian ground, so that the Martian atmosphere becomes dense, the time required is about 100 years.

Can humans survive on Mars, it only needs to change these points.

No, because there is no water source on Mars, and there is no oxygen, it does not meet the basic conditions for human survival.

No, the conditions for human existence, Mars does not have, mainly the unified energy field is not suitable for earthlings, air pressure, temperature, humidity, environment, biological plant diversity, air element proportion, the universe, the Milky Way, the solar system influence, all of which are not suitable for earthlings.

No. Although Mars and Earth have a similar structure. But Mars has not yet been studied. There may also be some potential dangers.

Although Mars has some conditions for the origin of life, it does not mean that human beings will be able to survive well on Mars. There are some problems on Mars that humanity faces.

Radiation protection remains an unsolved problem, and in fact, astronauts on the way to Mars are confronted with two main types of health-threatening radiation particles: one is the low-dose, but long-existing, galactic cosmic rays. The other category is solar energetic particles produced by solar flares and coronal mass ejections, which usually refer to protons with an energy of hundreds of megaelectron volts, which are much lower and shorter in duration than those of galactic cosmic rays.

Water is the source of life, and water on Mars is so precious that astronauts will not be able to survive on Mars without water. Although water is very abundant in the solar system, there was also a large amount of water on Mars, as well as many rivers and lakes. But no usable water source has yet been found on Mars, and the Martian liquid water that NASA has just announced is only toxic brine containing perchlorate, distributed on the steep slopes of a small number of Martian impact craters.

The water needed for astronauts to survive on Mars is still a difficult problem, so the reclaimed water system** has become very important.

So can humans really survive on Mars on their own? Although it has long been rumored that humans will colonize Mars, there are many problems and difficulties that will be needed to implement this idea.

At present, humans are unable to move to Mars, and there are many obstacles.

First, Mars does not have a magnetic field and cannot use it to protect against harmful radiation in the universe like Earth. About 4 billion years ago, Mars lost its global magnetosphere, and the current magnetic field is only a fraction of what it was then. The lack of a magnetic field causes the solar wind to come into direct contact with the ionosphere, and the solar wind gradually strips atoms from the outer layer, making the atmosphere thinner and thinner.

Similarly, without the protection of the magnetic field, the sun's particle bursts and cosmic rays reach directly to the surface of Mars, which is very fatal for humans who land on the surface of Mars.

Second, the average temperature on the surface of Mars is very low. The average is at -87 and -5 °C. Seasonal temperatures vary greatly.

The equator can reach as high as 35°C in summer, while the two-stage can be as low as -143°C in winter. But worse still, the temperature difference between day and night is also very large, because the thin atmosphere cannot store much solar heat, according to Opportunity, in the same place, the temperature is 30 degrees Celsius during the day and drops to 110 degrees Celsius at night. In fact, it is okay, compared to other planets, this is already within the range of human survival.

Third, the Martian atmosphere consists of about 96 percent carbon dioxide, argon and nitrogen as well as trace amounts of oxygen and other gases. There are a large number of tiny particles in the atmosphere, which are not only harmful to the human body, but also harmful to electronic devices. The key is oxygen, which is really our lifeline, what if there is no oxygen?

What may be needed is photosynthesis modification.

Mars is a very dry planet, and although water vapor is found in its atmosphere, it contains very little, only one percent of the desert areas on Earth; The atmosphere of Mars is very thin, 96 percent carbon dioxide, and very little oxygen; The surface temperature of Mars is very low; Mars has no magnetic field, and its atmosphere does not contain an ozone layer, so it is not immune to ultraviolet rays and various cosmic rays. All of these factors make it difficult for life to exist on Mars. Besides, Mars is too far away from us to move at the moment.
