Mars immigration design

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.

Mars is close to the earth every day, and its day is more than 24 hours, so a day on Mars is roughly equivalent 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.

Mars has an atmosphere, though it is 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.

The latest evidence about water shows that there may be water in the underground lakes and polar ice sheets of 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 was divided 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 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.

Due to the solar event, during the six-month trip to Mars, astronauts will sail 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?
