Why didn't the United States develop the moon first and focus on Mars?

In fact, there is not much surplus grain in the United States. If we develop the moon, we will certainly not spend less money as before. In fact, the previous landing on the moon in the United States was called "Apollo program", but if we want to develop the moon, it means that we need to constantly invest money there to maintain equipment, and the money spent may be dozens or even hundreds of times that of the previous landing on the moon.

Development costs are relatively high.

Whether it is an aerospace project or not, its cost is relatively high. Isn't it a joke that the high development cost led the United States to explore Mars without developing the moon first? Because Mars is farther away from the earth, it needs more technical difficulties and of course more funds.

But in fact, what the United States has done is only the exploration of Mars, not the real development of Mars. Although the amount of funds for exploring Mars is indeed much larger than that for exploring the moon, in fact, there is no need to maintain these equipment in large quantities, and even if it is forced to terminate, the loss will not be too great.

Because it is really necessary to develop the moon, it means that it still needs to invest a very large amount of money, and the equipment needs to be maintained for a long time, and the project cannot be terminated at will, otherwise the loss will be very large. For example, building a lunar base on the moon needs maintenance, but projects like the International Space Station will soon be terminated. How can a lunar base be built casually?

It is precisely because the amount of funds needed for development is larger that it is more necessary to be cautious before the project starts, and it is necessary to conduct full discussions and fully estimate the invested funds.

To explore Mars, you basically only need to send a probe to Mars. As long as the probe can complete the task, whether to maintain this equipment is of little significance to the follow-up. Therefore, the cost of exploring Mars is relatively small compared with developing the moon.

Maintain the advanced technology of the United States.

In fact, the original American moon landing plan was carried out under the stimulus of the Soviet Union, because the first artificial earth satellite and the first manned spaceflight project were completed by the Soviet Union.

This is a great blow to the United States in the cold war, so the United States has made the same achievements even in artificial earth satellites or manned space projects, but the first one was taken away by the Soviet Union, which is of little significance to the United States, so the United States needs to snatch the first moon landing.

America's plan in this regard has also been realized, becoming the first country to land on the moon, an achievement that has not been surpassed by other countries so far. So in a sense, the United States has proved to the world that American technology is the most advanced in the world.

In fact, this is basically because some people in the United States still hold the Cold War mentality. Because the moon has verified American technology, there is no need to spend more money on the moon. For Mars, compared with many other countries, it is an unknown field. Therefore, it is of great significance for the United States to consolidate and explore the status of Mars, which proves the superiority of American technology.

In fact, Americans have been calling for immigration to Mars, but in fact, our understanding of Mars is still very shallow, and whether there is life on Mars is still being explored at the first level. Therefore, the United States is so willing to explore Mars, in fact, there are some deceptive meanings. I hope that this will attract more countries to explore Mars, which will drag down other countries economically and make other countries never surpass the United States.

To sum up, then the space exploration plan involves two aspects, one is that it needs a lot of capital investment, and the other is that it needs relatively high technical support. So the United States only needs to explore more fields to show how strong they are.

Everyone knows that the moon is the closest celestial body to the earth. Intuitively speaking, developing the moon is the most ideal, because the distance is close and the cost will be much lower. However, NASA and other private organizations in the United States are just the opposite. They no longer focus on the moon, but on exploring and immigrating to Mars. This seems illogical. Why? I think there are many reasons for this. Let's analyze it together.

Time of day

Mars is very close to the earth, and its day is more than 24 hours, so a day on Mars is similar to a day on Earth. But a day on the moon can be as long as 28 earth days, which seems very different. In addition, because the day on Mars is relatively short, the temperature difference between day and night is not obvious. On the moon, it is very hot during the day and very cold at night. The temperature difference between day and night of the moon is about 300 degrees Celsius. The temperature difference between day and night is so great that it is difficult to design a suitable life support system.

atmosphere

Mars has an atmosphere, although it is very thin. Although it is not a big atmosphere, there is at least one atmosphere. Mainly carbon dioxide, which is very useful for plants, but really bad for us humans. The atmosphere allows the wind to blow, which helps to balance the temperature difference between day and night. The moon has almost no atmosphere. At the earth's sea level, we breathe an atmosphere containing 10 trillion molecules per cubic centimeter. In contrast, the moon's atmosphere has less than one million molecules in the same volume. Because there is very little atmosphere on the moon, no wind can really transfer heat from hot day to cold night. The thin atmosphere of Mars can more or less block a beam of harmful EUV and high-energy particles from the sun. Nothing on the moon can stop people from being hit. It seems that on Mars, it is possible to live on the surface. But it will still receive a lot of radiation. They are really not very good from the point of view of radiation, but if you have to choose one, Mars may be better.

water

The latest evidence shows that there may be water in underground lakes and polar ice sheets on Mars, which is relatively possible. Obtaining water at any time is not only important for human survival and plant growth, but also can realize self-sufficiency of Mars without frequent replenishment from the earth. We will be able to use it to make oxygen more conveniently to ensure breathing. It seems that the moon can hardly find water.

gravity

The gravity on Mars is stronger than that on the moon. Gravity on Mars helps to keep the atmosphere on the planet, and also helps to keep objects on the ground, making our bones stronger.

Scientific value

There is evidence that the moon may be a large part of the earth that split a long time ago. Mars is a completely independent planet, which develops independently and has a lot of cool geology. Many people are convinced that there may really be life on Mars. This possibility is fascinating, so scientifically speaking, Mars is much better than the moon.

There are so many advantages of Mars mentioned above, so let's talk about disadvantages.

First of all, the hard injury is distance.

Because the moon is very close to the earth. This can save a lot of costs. If you want to go to Mars, you must make preparations for a long time before you can start providing water for immigrants and rocket fuel to Mars. In order to send large objects to Mars. This process will cost a lot of money and require a huge rocket to achieve this goal. It takes only three days to reach the moon, but it takes at least six months to reach Mars. Because the year of Mars is much longer than that of Earth, which is almost two Earth years, the planets are arranged in the latest way, only once every two years. In about two weeks, you can launch a rocket from the earth to Mars in the most economical way (called "launch window"). If you miss these days, you can only make an appointment two years later. On the other hand, because it is close to the moon, it is easy to reach. In fact, because the moon goes around the earth, we can go there anytime and anywhere. Therefore, there are great security risks, and it is likely that people will be rescued from the moon. On Mars, people may be trapped for several years beyond their reach. In addition, if the earth and the moon talk, there will only be a delay of a few seconds. The delay time of Mars is between 4 and 24 minutes, depending on whether Mars is on "our side" or opposite the sun. Such a long signal delay is a big problem.

Solar events

During the six-month trip to Mars, astronauts will travel in the vast space in a small boat. If a big solar event occurs, resulting in a significant increase in radiation, which often happens and the risk is high. Unless there is a more advanced radiation shielding device on board, the crew is likely to die of excessive radiation dose. Solar events may also happen on the way to the moon. However, it takes only three days to get there, so it is easier to avoid the time when radiation bursts may occur.

So from the comparison of these situations, Mars is better. Because of the possibility of life and the very interesting geological situation that happened a long time ago, Mars provides a better opportunity for scientific exploration. If something terrible happens on the earth one day and life cannot be sustained, then Mars will be a better planet for immigrants, because it is possible to find water, higher gravity and atmosphere. More likely to be suitable for survival.

In fact, these may not be the point. America's National Aeronautics and Space Administration (NASA) pays attention to Mars and launches so many Mars probes at high frequency because they have discovered something important. NASA has been keeping secrets. Many important discoveries on Mars will not be published. The picture information and news released by NASA are all disguised information. Of course, the panorama of Mars, which has been brainwashing everyone, has always shown that Mars is a barren planet with no signs of life or even water. Last month, the European Space Agency released a high-definition mosaic of Mars, showing you a completely different Mars. This picture is a mosaic of images taken by the Mars Express detector, and the picture is absolutely shocking. It turns out that Mars is so beautiful that it is simply the second earth. What do you think of the larger ice cap at the poles, which shows the absolute signs of life?

Developing the moon is more difficult and costly than manned landing on the moon and exploring Mars, and the strength of the United States today is unbearable. As we all know, the moon has many scarce resources of the earth, only 380,000 kilometers away from the earth, but the technology is not enough for exploitation.

What seems completely illogical to the subject is precisely the most logical thing. Since it is impossible to develop the moon at present, just launch some detectors to detect it. There is no need to spend all the space power on the moon. As a result, we also saw that Americans made the largest solar system exploration plan. The spacecraft flew into interstellar space, explored eight planets and some of their satellites, developed the Hubble telescope, took the lead in building the space station, cooperated with others to build the James Webb space telescope (not yet launched), and repeatedly launched unmanned probes to make a soft landing on Mars. They haven't given up the moon, and there are probes in the orbit of the moon.

If the United States develops the moon at this time, it will crowd out many current space exploration projects, which may not be enough. It may not be difficult to send a man to the moon with modern space technology, but it will take many times to launch a heavy rocket to exploit the moon resources and bring them back to earth. Heavy rockets mean high costs. Without heavy rockets, what can be brought back from the moon is very limited and not enough. How do we develop them? Therefore, the current American solar system exploration plan is the most reasonable, constantly verifying technology. When humans have the ability to develop the moon, it is good to turn around and develop it. There's no need to hang it on the rope.

Mars exploration is another aspect. Relatively speaking, it is only an exploration activity at present, not a development activity. The investment is much smaller than the development of the moon, and American technology can bear it. In fact, they are also the countries with the largest number of unmanned probes landing on Mars.
