Should humans rush to immigrate to Mars?

Musk brought a topic of fire, that is, immigration to Mars.

Although his behavior is more of a performance, the practical significance is not as great as it seems, but it is still admirable. In him, people saw that an individual can also promote a great cause.

With the current rocket launching technology, it is unrealistic to immigrate to Mars on a large scale. This is not to say that it is technically impossible, but economically unrealistic. Decades ago, man landed on the moon many times. Landing on Mars is nothing more than spending more money and building bigger rockets. The money for five moon landings is probably enough to send a few people to Mars.

However, after the Apollo moon landing program, mankind has never been to the moon again, not because it is impossible, but because it is uneconomical and unnecessary. It is not cost-effective to bring back a few tons of gold at a time.

Today's rocket technology is essentially the same as that of Apollo landing on the moon. Are driven by chemical rockets. If Musk wants to go to Mars, he also uses chemical fuel rockets. The only technological breakthrough he can get is recoverable rocket technology. But this is actually a technical engineering problem. In today's advanced automation technology, it is basically no problem to fine-tune the rocket attitude to realize rocket recovery. As long as you are willing to spend money, try it several times.

In fact, China already has an entrepreneurial team, and some rockets have been recycled, but there is still a certain gap compared with Musk's technology. But this gap is nothing more than a matter of trying several times, not a fundamental gap.

Rocket recovery technology, the main problem to be solved is how to land the rocket on Mars. Many spaceships landed on Mars successfully, but many crashed. The reason is that a few minutes after landing is the time of death. With the maturity of rocket recovery technology, when landing on Mars, the aircraft can land smoothly with the help of the rocket's reverse thrust.

As for launching spacecraft out of the earth and the long distance from the earth to Mars, we basically rely on the original. As for how to build a fuel device in near-earth space to provide fuel for spacecraft, it is a basic technical project, just like aerial refueling of aircraft. As long as a country is willing to spend hundreds of billions to do it, it is basically the same.

Therefore, whether human beings can become an interstellar species, the most critical issue is power, and the power device should be fundamentally changed. With the present chemical rocket technology, it is unrealistic to move to Mars on a large scale. It is possible to send hundreds of people to Mars for free. But it's ok for these people to cultivate the earth's environment in South America, but it's absolutely impossible to cultivate it on barren Mars.

Apart from transforming Mars so far, it is necessary to build a self-sustaining Mars base, which needs at least tens of thousands of people, and transport a lot of basic materials to build a self-circulating ecology there. The volume of these materials is tens of thousands of tons. It is impossible to transport so many materials to Mars, even if the earth is bankrupt now. The so-called self-sustaining Mars base here is based on the assumption that once it is built, even if the earth no longer transports a person or an object, the base can continue to operate, at least for decades.

Or the current chemical rocket, the human Mars migration plan, will only be a replica of the Apollo plan. In other words, it is a "one-day tour" activity, which is small in scale and even less sustainable. When human society is still very enthusiastic about this matter, it is willing to spend hundreds of billions or even trillions of dollars every year to send hundreds of thousands of people to Mars. But when human beings are no longer enthusiastic about this and are unwilling to spend this money again, the process of forced "blood transfusion" stops. Once the blood transfusion is stopped, the Mars base built at a huge cost will be abandoned in a few years.

There is a scene in the TV series "Fierce Knife in the Snow" in which Xuanyuan Jingcheng challenges his grandfather Xuanyuan Pan Da for his daughter. Xuanyuan Jingcheng's martial arts level is relatively low, but he forcibly increases the force value through various means. Xuanyuanpan is the ancestor of Xuanyuan family. He wants to have a double break with Xuanyuan Qingfeng, the daughter of Xuanyuan Jingcheng, that is, to take a concubine. Xuanyuan Jingcheng, as a father, certainly didn't do it, so there was a war. Xuanyuanyan is the heaven, and Xuanyuan Jingcheng is far away. In the process of fighting, Xuanyuan sincerely promoted his cultivation to the realm of heaven in a short time at the expense of burning his own life. Not yet. Later, I was promoted to the land god fairyland, and finally defeated the Xuanyuan Emperor Pan in heaven. However, Xuanyuan Jingcheng itself did not have the strength, but tried its best to maintain the fairyland of the land god for a few seconds, and then the oil was exhausted.

With the present chemical rocket technology, human beings landed on Mars by force, which is a bit like Xuanyuan Jingcheng forcibly reaching the realm of immortals, but handsome for a second. I will soon find that this is beyond my power.

One minute on stage, ten years off stage. When your skills are not perfect, you don't need to rush to perform on stage, but you should exercise in peace under the stage.

There is nothing wrong with making humans an interstellar species. This is definitely a great ideal. Life is like a little firefly in the vast starry sky. In fact, it was very fragile, and I accidentally went out. Interstellar reproduction is an important means to maintain the development of civilization. This is absolutely no problem.

However, to achieve this goal, the most important thing is to conquer the rocket power technology, rather than rushing to launch the Martian immigration movement. Instead of spending one trillion yuan to send ten thousand people to Mars, it is better to spend one trillion yuan to conquer rocket power technology. All kinds of nuclear-powered rockets and ion-powered rockets have been made. Invest 654.38+000 billion in R&D every year, and spend 1 trillion. This money is just a waste of water. You can hear it by ringing it.

In the last century, the United States carried out two major projects that shocked the world. One is the Manhattan project to build an atomic bomb, and the other is the Apollo project to put a man on the moon. These two plans involve hundreds of thousands of people and cost hundreds of billions. But the end result is completely different. The atomic bomb planned by Manhattan is still in use, which is the greatest deterrent between countries. The Apollo project, which also cost hundreds of billions, is like having a carnival party. After the party, there was nothing.

Of course, you may say that many technologies have also been derived in this process, such as IBM's computing technology. It is true, but compared with the cost of this project, it is not cost-effective. Besides, didn't the Manhattan Project promote the development of computer technology?

Spend hundreds of billions, no matter what you do, you will definitely hear some noise. But the actual benefits of spending money in different places are different.

No matter how much cost Musk saves, if tens of thousands of people want to immigrate to Mars, there are not hundreds of billions that cannot be obtained. Such a large sum of money, if used for the research and development of new rocket technology, will certainly be more beneficial to mankind.

Remember, our ultimate goal is to make mankind an interstellar species. To achieve this goal, the most important thing is to overcome the rocket power technology. If this problem is not solved, spending hundreds of billions to send tens of thousands of people to Mars is essentially to let human beings watch a fireworks show, which will soon be silent after the excitement.

Pay attention to the lining, not the face. Sometimes when you lose face, you lose your lining.

I feel that the Apollo moon landing program in the United States not only did not push humans out of the earth, but had the opposite effect. Because, the conclusion presented by this project to the world is: after spending so much money, you will have to go to the moon several times in the end. What's the difference between going on a "just leave" tour after losing everything? The Apollo program in America cost a lot of money and energy. In fact, if this money is used to develop rocket technology, decades will not pass, and rocket technology will almost remain stagnant. We have been using chemical-powered rockets, and we can't even see the shadow of a nuclear-powered rocket, ion rocket or proton rocket.

If we spend hundreds of billions on a Mars migration project now, the update of rocket technology will be even more hopeless. With so many resources. If you use them here, they will disappear there.

From this perspective, Musk may be doing bad things with good intentions. His greatest wish in life is to make mankind an interstellar species, but the result of his efforts may run counter to his wish. In the short term, his migration to Mars is to push mankind into deep space, but in the long term, it is counterproductive.

Humans don't need to burn the last drop of blood for a short time to reach heaven, but slowly improve their cultivation and let themselves slowly rise to heaven. After all, we don't have Xuanyuan rock to face immediately, and there is still time.

Mars is there and won't run away. We can completely upgrade the rocket power technology and build a nuclear-powered rocket within one hundred years. At that time, large-scale immigration to Mars will be a relaxed and pleasant thing. With the blessing of new rocket technologies such as nuclear-powered rockets, it is possible to send millions of human beings and millions of tons of materials to Mars, and build a huge base on Mars to achieve sustainable immigration and base construction. And with the blessing of these technologies, our goal is not only Mars, but also planets in the solar system, and we can fly out of the solar system.

In my opinion, wormholes, time tunnels, curvature engines that realize the speed of light, and so on. It's too far away, and it may not be realized in ten thousand years. However, nuclear-powered rockets, ion rockets and other technologies that cost trillions and take decades may make substantial breakthroughs. Why not give it a try?
