Why is it so much more difficult for humans to land on Mars than on the moon?

Because of the extreme environment on Mars, the challenges and problems brought to mankind are far more complex than those on the Moon. We all know that in the 21 st century, mankind has made sufficient improvements in many fields of science, and the discovery of many new theories and the application of new technologies have brought earth-shaking changes to our lives.

However, to this day, with the mystery and vastness of the universe, we still have many "unsolved mysteries" that have not yet found perfect answers. Even in the solar system, which is one light-year in diameter, there are countless problems that are still very difficult for modern people.

For example, "Log on to Mars". Since the sixties of the last century, mankind has put many probes on Mars, leaving our traces on Mars; Probes such as Curiosity and Spirit have made numerous discoveries on Mars.

However, to this day, human beings still cannot land on Mars in a manned way, and the problems brought to us by landing on Mars are far more complex and tricky than those on the moon. Why is this happening? The answer is actually quite simple.

First of all, the surface climate of Mars is quite extreme, and it is not the same as that of the Moon. According to the analysis of Martian geomorphological characteristics provided by NASA in 2017, an extremely large sandstorm will occur on the surface of Mars every two days or so; This is undoubtedly a big challenge for astronauts.

Secondly, the atmosphere on Mars is scarce, and all kinds of cosmic rays and radiation, almost without barriers, can directly hit the surface of Mars, which is also one of the problems we need to solve at present.

Secondly, the magnetic field on Mars is also very incomplete, and on Mars, the communication between astronauts and the Earth's headquarters is likely to be seriously disrupted. When the time comes, I am afraid that it will "call the heavens and the earth unspiritual." Therefore, Mars has not yet been completely conquered by us.

However, late last year, NASA said it was ready to launch a plan to land on Mars within five years.

Is landing on Mars much more difficult than landing on the Moon?

Because the moon is the closest to us, we humans have been able to go up to the moon. However, Mars is too far away from us, and we can only use some machines to explore Mars first.

Because the distance is farther. The distance between the Earth and the Moon is about 400,000 kilometers, the distance between the Earth and the Fire is about 55 million kilometers and 400 million kilometers, and at the closest time, it takes nearly 4 minutes for the message sent by the Earth to be received by Mars.

Because the environment of the two is very different, and secondly, the distance is very far, and Mars is very far from the Earth.

Foreign scientists consider it a curse, but besides that, why is it so difficult for humans to land on Mars?

When landing on Mars, the distance of Mars is farther, and if his Mars is larger and larger, it is easy to break those landers in the process of going down.

How difficult is it to land on Mars than on the Moon? Let the scientists tell you the answer.

Of course, it is more difficult to land on the moon. Because landing on the moon cannot land from its front, it can only land softly from its backside, but if you land softly, you will lose all contact with the earth.

Landing on Mars is more difficult. Because Mars has not yet been fully explored by humans, there are still many unknown dangers.

How difficult is it to land on Mars than on the Moon? Let the scientists tell you the answer.

But landing on Mars is too dangerous, the Moon is a satellite of the Earth, and it only takes about 30 days to reach the Moon, but it takes half a year to reach Mars. It is known that Apollo 11 was almost unable to return due to power problems. The distance between the Earth and the Moon alone caused problems for Apollo 11, not to mention the distance between the Earth and Mars.

Another reason for not landing on Mars is that the environment on the surface of Mars is too harsh, and even if you ignore the strong temperature difference between day and night, there are winds and sand that cannot be ignored.

While we can't send people to the surface of Mars, all countries are sending probes to Mars. Although many probes have arrived on Mars one after another, it will take about two or three hundred days. If humans want to land on Mars and return home, it will take at least 400-700 days.

During this time, food**, astronauts' health, and fuel are not guaranteed. And the weight and space to carry the food needed by astronauts for about 400-700 days is also very large. In addition, the weight of the fuel back and forth is also heavy, which is bound to make it more difficult for manned spacecraft.

But there are no rocket launchers and no fuel on Mars, and it is almost impossible to get rid of the gravitational pull of Mars. The distance between Mars and the Earth is much greater than the distance between the Earth and the Moon. The average distance from the Earth to the Moon is about 380,000 kilometers, but the shortest distance from the Earth to Mars is also 55 million kilometers, because of the distance, there are many problems.

The first is the issue of spacecraft thrust. If you want to get to Mars, the fuel for the spacecraft will increase significantly. As its own weight increases, technicians need to increase the stability and firmness of the spacecraft by more than a level, which is not something that can be solved in a day or two.

Unlike the space station, which has a supply from Earth every once in a while, can the freshwater filtration system, the food supply system, and the respiratory system function normally for so long? If something goes wrong, the manned spacecraft will become a living grave. Mars is different from the Moon in that it has an atmosphere on its surface, and because it is about nine times more massive than the Moon, its gravitational pull is much greater than that of the Moon.

The lunar manned landing module does not need to consider the problem of overheating of the aircraft surface during the descent process, but if you want to land on Mars, you need to add heat insulation, and rocket thrust alone cannot make it land safely, and other auxiliary equipment is needed.

Because if you want to land on the moon, you only need to have certain technology, and our country has such technology a long time ago, but if you want to land on Mars, then you need to understand some conditions on Mars at this time, and it is very likely that there will be dangers.

This is because the geographical environment of Mars is very harsh, and the active temperature is also very high, and the absence of air and water is not suitable for human habitation.

Because Mars is farther away, Mars is larger, and some of the gases on Mars are denser, so it will be so difficult to land on Mars. Because some of the materials on Mars are very rich, and through the study of these materials, Mars can be better explored, so it is so attractive to humans.

Mars is the planet closest to Earth, while the Moon is a satellite of Earth, so it's easier to get to the Moon. It is very likely that there is life on Mars, which is also the purpose of human research on Mars.

Because the temperature on the surface of Mars is relatively low and the climate is relatively harsh, it is very difficult, because Mars is the planet that mankind has found to be suitable for human habitation so far.

It may be that the technology is not enough, and it is related to aerospace communications, and it may be that there is no way to develop space communications well, so there is no way to land on Mars.

It's not that there is no way to land on Mars, but there is no need to land on Mars, and according to the exploration of space science and technology, there is nothing of value on the surface of Mars.

Because Mars is farther away from us than the Moon, we need some equipment to transmit signals, and we are not particularly mature in this regard.
