Why are humans reluctant to land on Mars?

The first difficulty in landing on Mars is the distance. We know that the average distance between the Earth and the Moon is 10,000 kilometers, and the distance between the Moon and the Earth at perigee is 10,000 kilometers, and the distance from apogee is 10,000 kilometers. The distance between the Earth and Mars reached 55 million kilometers at the closest and more than 400 million kilometers at the farthest.

Because Mars is so far away from Earth, it takes about a very long time for human-built spacecraft to land on Mars.

Moreover, none of the above vehicles are manned vehicles, and it is more than 100 times more difficult to achieve a manned landing on the moon than it is now. This is because human beings have weight, but also occupy a certain volume, and human beings need energy to maintain survival, from the earth to Mars, human beings need a lot of energy** and fresh water, these weights make manned spaceflight need a very strong carrying capacity. Secondly, the environment of Mars is very harsh, there is no global magnetic field, and the atmosphere is relatively weak, so that cosmic rays can directly enter the surface of Mars.

That is, the surface of Mars cannot be grown with plants. Therefore, only by preparing enough food and energy on Earth can the astronauts be able to work normally after reaching Mars, and they also need to be prepared to return fuel, food, and fresh water to Earth. This has virtually greatly increased the difficulty of manned landing on Mars.

Finally, the plan to land on Mars, although romantic, is full of dangers, and if any accident occurs during the landing on Mars, humans on Earth will not be able to help. Coupled with the work that astronauts can do, the Mars probe can also do it, so there is no need to spend so much effort to achieve a manned landing on Mars. This has also led to the fact that although 51 years have passed since the human landing on the moon, there has still been no manned landing on Mars.

Although it is so difficult to land on Mars, there are still many countries that have taken landing on Mars as the next stage of their goal, because Mars is a planet with a relatively similar environment to Earth in the solar system, although Mars has no atmosphere and a global magnetic field makes it unsuitable for life here, but scientists still want to explore Mars and study Mars to prepare for immigration to other planets. Brett Drake, a researcher at NASA, said that a human landing on Mars is still a future exploration goal.

Some scientists even believe that Mars is the hope of mankind.

Although Mars is a planet very close to the Earth, the land surface of Mars has no oxygen and water, which is not suitable for human life, so human beings are reluctant to land on Mars.

It's not that they don't want to land on Mars, but that human beings have the technology to send astronauts up to the probe.

Because the difficulty is on the one hand, and the value is relatively small, there is no value to refer to, and the difference between its environment and the earth is really too big to be useful.

Why are humans reluctant to land on Mars? Technology is not a problem, it is a constraint on human beings.

1.The temperature at the equator on Mars can reach minus 20 degrees Celsius, while there is a large amount of dry ice on both stages of Mars, and the temperature of dry ice is minus degrees Celsius and below, indicating that the temperature at the poles of Mars is very low. The average temperature on Earth is around minus 15 degrees Celsius to 35 degrees Celsius.

So it's not suitable for login.

2.Mars' magnetic field is weak, making it difficult to protect against the solar wind. And the solar wind can disable satellites, and it can also make it difficult for many organisms to survive or even die. It can also cause a lot of equipment to fail. Humans are unable to live normally after landing.

3.The atmosphere of Mars is extremely thin, and it is difficult to block ultraviolet rays, which can cause significant damage to living things.

4.Ninety-five percent of the Martian air is carbon dioxide, and less than 1 percent of the oxygen available for breathing.

5.Too far from Earth. At the farthest point, it can hit 4000000000 kilometers.

Recently, it is also about 55 million kilometers. Spacecraft fly just close to Earth, and it costs thousands of dollars per kilogram of load. Not to mention Mars.

6.There are huge sandstorms on Mars, which are larger than those on Earth.

7.The cost of developing protective clothing that can withstand the harsh environment of Mars is extremely high.

8.Do not say.

As of 2020, no humans have ever been on Mars. It is much more difficult for humans to land on Mars than the Apollo moon landing program. With today's rocket technology, it takes up to nine months for astronauts to reach Mars, and living in zero gravity for long periods of time can cause tremendous damage to astronauts' bodies, such as irreversible changes in retinal blood vessels, resulting in vision loss or even loss.

Mars is the fourth closest planet to the Sun and the second smallest planet in the solar system after Mercury, and is one of the four terrestrial planets in the solar system.

In ancient Europe, Mars was called "Mars", the "god of war" in ancient Roman mythology, and also known as the "Red Planet". In ancient Chinese, it was called Yingfu because it was like fire, and its position and brightness often changed to make people unpredictable.

Its orange-red appearance is due to the fact that the surface of the earth is covered with hematite (iron oxide), Mars is about half the diameter of the Earth, and the inclination and rotation period of the axis of rotation are similar to those of the Earth, but the orbital period is twice that of the Earth. Mars is up to as bright as it is, but it is fainter than Jupiter most of the time.

The first reason is that the fire ground is too far away, because both planets orbit the sun, even the closest distance, 360,000 kilometers, judging by the current level of technology, it will take at least a year to reach at the current speed of human beings.

01 For thousands of years, the universe has been attracting the attention of human exploration, although it has not yet been able to land on Mars, but many instruments have detected various landforms on Mars, which has also laid a solid foundation for the successful landing on Mars in the future. NASA has launched Mars probes many times, and has been successfully landed on Mars by the rover, and has been successfully extracted and returned by many field survey equipment on Mars, but there is still a long distance to explore before the manned vehicle lands on Mars, mainly because it takes too long, and there is no flight equipment that can accommodate so many resources to successfully bring people to Mars.

02 Another reason is the lack of power, although this is the easiest near-Earth planet for human beings to land so far, but there is no strong motivation for human beings, because the moon is relatively close to the earth, and it is also the only satellite of the earth, the difficulty of landing is not very large, but due to the distance of Mars, even if you land on Mars, you can only bring back some survey materials, which is not very strong for aerospace scientific research and research, and due to the current international factors, No country has put the Mars on the agenda now, and all space races are actually the result of great power competition, and space is mainly developed for military reasons.

03 At present, there is not enough motivation for people to explore how to get to Mars, and it is for this reason that this plan has been put on hold, but there are many literary and artistic film and television works about Mars, from which you can learn about the bold imagination of other artists on Mars, and believe that in the future, people will finally be able to land on Mars.

1. As of 2020, humans have not landed on Mars. It is much more difficult for humans to land on Mars than the Apollo moon landing program. With today's rocket technology, it takes up to nine months for astronauts to reach Mars, and living in zero gravity for long periods of time can cause tremendous damage to the astronauts' bodies, such as irreversible changes in the retinal blood vessels, resulting in vision loss or even loss.

2. To go to Mars, the development of several technologies is urgent, and the spacecraft must not only land safely on Mars in a harsh environment, but also have the ability to take off on Mars and send astronauts back to Earth.
