Humans have been studying Mars for a long time, why haven t they been able to get on Mars so far?

It has been almost 50 years since humans landed on the moon, although humans have always had plans to land on Mars since the moon landing, but they have not yet made the trip, and it is estimated that in the next ten years, the hope of human landing on Mars is still very slim, so why has it not landed on Mars so far? How difficult is it to land on Mars?

In general, there are three main reasons, namely high technical requirements, large capital consumption, and no practical value.

First of all, the technical requirements are high, landing on Mars and landing on the moon are still very different, Mars is much farther from the earth than the moon, the average distance between the moon and the earth is 380,000 kilometers, but Mars is 55 million kilometers away from the closest, and the farthest time is up to 100 million kilometers, human landing on Mars, even when Mars is relatively close to the earth, it takes months to go to the journey alone, and when investigating on Mars, it usually takes to return when the next Mars and the earth are relatively close. In this way, it will be a long time, and the time is calculated by years, unlike landing on the moon for a few days.

In this case, the technical requirements for landing on Mars are also very high, which are mainly reflected in two aspects, that is, high energy consumption and more equipment.

High energy consumption is to launch the Mars spacecraft and astronauts into the Mars orbit, a rocket with great thrust, and it needs to consume a lot of fuel back and forth, and it is very necessary to carry a lot of things with more equipment, such as various probes, Mars landing equipment, return equipment, astronaut living equipment, etc., which are too much more than what the space station needs, and to do this, it is even necessary to transport the spacecraft, return equipment, a large amount of fuel and the things that astronauts need to be transported to space near the earth. After assembling it, it is accelerated by its own engine, and then sent to Mars using the Earth's gravitational slingshot effect, but it also requires a lot of energy during the journey.

However, technology is not the main reason, although the Americans have long had a fire exploration plan, but there has been no action on the project, that is, because this plan is too expensive, in the sixties and seventies of the last century, the Americans spent $25.5 billion on the lunar exploration project, if it is put to the present, just considering the price of ** range will have to be more than ten times, if you land on Mars, the cost of funds will definitely be higher than landing on the moon, and it is difficult for Congress to approve it.

In fact, today's human landing on Mars is more symbolic in terms of value, because in terms of technology, human beings have not yet developed the possibility of Mars, and the population on the earth is not enough to the extent that resources are scarce, so there is no urgent need to develop Mars, and the reason why the Americans did not land on the moon again after landing on the moon that year, in addition to the large cost, an important reason is that in addition to the scientific research value and the symbolism of the first country to land on the moon, there is no practical significance. This is the reason why after the Apollo moon landing, human lunar exploration and fire exploration programs have been shelved, and the United States and other countries have chosen to launch unmanned probes, so that the cost is not too large, and many desired scientific research results can be achieved.

Humans were able to land on the moon because the moon has less gravitational pull than the Earth, and it can fly back even without the need for a launch pad. The gravitational pull of Mars is greater than that of Earth, and if you want to go back from Mars, you need at least three times the thrust on Earth. What the earth needs a launch pad to complete, it is difficult to complete without a launch pad on Mars, so human beings are now on Mars and there is no return.

Because Mars is very far away from the Earth, and humans have not yet mastered the technology to land on Mars, they have not been able to land on Mars so far.

With the current level of science and technology on Mars, it is difficult for us to survive on Mars, there is no way to log in, and many difficulties have not been overcome.

In my opinion,The delay in human landing on Mars is not because they have lost interest in Mars, but because with the current level of science and technology, there is no way to allow astronauts to travel back and forth between the Earth and Mars, let alone completely solve a series of problems that may be encountered in landing on Mars。That is, it is not that humans do not land on Mars, but that the conditions for landing on Mars are insufficient.

You must know that human exploration of outer space has never stopped, and Mars is the solar system.

One of the most suitable planets for human exploration, naturally by scientists.

of widespread attention. But it is important to understand that landing on Mars is not so simple, because the distance between Mars and Earth is very far, so how to ensure that the manned spacecraft has enough fuel to travel between Earth and Mars is already a headache for scientists。In such a situation, even if scientists have the intention to start the plan to land on Mars, they can only postpone it, after all, if the problem of round-trip cannot be solved, it is not of much significance to just let astronauts land on Mars.

Besides, in addition to the problem of round-trip, there are many problems that need to be solved, such as the residence and survival of astronauts on Mars. This is because landing on Mars is not an easy task, and scientists naturally need to consider multiple aspects when implementing this plan to ensure that the plan is foolproof to a certain extent, otherwise the plan is likely to fail. It can be said that if all the problems that may be encountered are not solved one by one, it is unlikely that mankind will directly start the plan to land on Mars.

In addition, the cost of landing on Mars is very high, so if the plan to land on Mars goes unexpected, the damage caused is unbearable for anyone.

It can be seen that the fundamental reason for the delay of human beings in landing on Mars is that they are not ready, or that with the current level of science and technology, there is no way for humans to complete the idea of landing on Mars, not because human beings are not interested in Mars.

Mainly because it is too difficult to land on Mars, and the technology is not enough. Humanity has not lost interest in Mars.

It's not that you can't log in, it's that you can't log in. Because Mars is so hot, if you get close to him, there is a good chance that he will be cooked. It's not that there's a loss of interest.

In the 21st century, the scientific and technological strength of mankind has been greatly improved, and we can completely build closed space capsules to ensure the safety of astronauts, and it can be said that there are almost no technical difficulties. In this regard, G. Scott Hubbard, a former NASA associate professor at Stanford University, said that in the past few decades or even hundreds of years, countless ideas have been proposed, but none of them have been realized. Frankly, it's not technology but politics that are limiting the landing of humans on Mars.

You know, on Mars.

Not a distant fantasy, in the 21st century, the dream of a human landing on Mars will become a reality.

Mars is far from Earth, and it takes a long time for a spacecraft to fly to Mars. At present, humans have only spent 326 days in space, and if astronauts can live on a space station in low-Earth orbit for more than three years, then it will no longer be a dream for humans to go to Mars.

Within 100 years, in 2100, they landed on Mars.

You can do it now! But the financial resources are too great.

If scientists can find water on Mars, humans could land on the Red Planet in 20-30 years, the head of NASA's planetary ground exploration team said on Wednesday. Two "robotic geologists" powered in part by solar, the Rover Mars Rover (MER), have traveled three miles (5 kilometers) on the surface of Mars and into craters since January, sending back a large amount of data on the composition of what scientists have long believed to be Earth's sister planets.

When asked when astronauts will reach Mars, MER mission manager Arthur

If landing on Mars is the first option, Thompson said, his guess is that it will take 20-30 years at the earliest. Two MER robots, Spirit and Opportunity, have found evidence that Mars had a large amount of water long ago, which is very important for scientists who want to know that life was or still exists on Mars. Without water, the dream of sending astronauts to Mars, imagining Mars as a planet with sandstorms, rust-colored rocks, red skies and blue sunsets, would not be possible.

The process of landing on Mars takes 11-12 months, astronauts cannot carry enough water, and too much water will consume fuel, and water is also needed to cool the spacecraft.

Scientists have found a canyon on Mars that "makes the Grand Canyon a small canyon" and that liquid water may still be present, Thompson said. He said there were signs of water seeping out from one side of the canyon and evaporating as it flowed, and they believed the phenomenon was continuing. The three artificial satellites currently orbiting Mars are constantly gathering information, and Thompson said that if water exists, it is believed that the chances of finding life will be greatly increased.

Bush wants to build a permanent space base on the moon and send astronauts to Mars at some point in the future. NASA's vision is to send at least one atomic-powered robot to Mars and establish a Mars Science Laboratory (MSL) by 2009. NASA's director Sean

O'Keefe said last week that it would cost at least $2.2 billion to get the shuttle back into space after the Columbia crash.

Thompson said NASA has ample budget funding ......But they almost convince us that they want to carry out the MSL program, which occupies a very high place on its agenda, and his understanding is that the Mars Program Office will be funded in the coming years. The cost of a MER is $800 million, but the cost of the MSL is unclear. Thompson said the MER robot is scheduled to end its mission in April this year, but is doing well now and will be available until next year.

It can be very fast, or it can be relatively distant

It is estimated that it is not possible yet.

Today's flying machines are not that advanced.

A Dutch company has recruited Martian Warriors to land on Mars by 2023, and NASA plans to land on Mars by 2030.
