Pupils often say that they will go to the moon for their holidays. When will it really come true?

With the development of science and technology, mankind will eventually move towards the sea of stars, and interstellar travel will no longer be our dream. In the future, the 1 station of human interstellar tourism must be the companion moon of the earth, because it is the closest to our earth, with an average of only 380,000 kilometers, and human beings have landed.

American Apollo planned to land on the moon 50 years ago, and predicted that Americans would return to the moon in the future 10, and China would probably land on the moon for the first time after 10. Other space powers in the world also have plans to land on the moon within 20 years, and space exploration technology companies such as Musk have taken human landing on the moon as the goal of market development, so when it is easier and easier for humans to land on the moon,

Where is the holiday tour? Can walking on the moon be realized in your lifetime? It should be said that some people living on the earth today can be realized, but the number is very small. So when will this moment come? It is estimated that in the next 20 years, there will be a moon landing activity for the purpose of tourism, which is likely to be completed by a private space development company, because such a company is flexible in system and simple and direct in making profits in the market. As long as it is technically feasible, it is easy to realize.

The previous lunar sightseeing tour should be around the moon, because it is easy to realize. The Long March 5 launched by China a few days ago can do such things, such as sending shenzhou spaceship to the moon orbit and then coming back. However, if you land on the surface of the moon, you can't return because you can't carry more fuel. The Falcon 9 heavy rocket made by Musk's space exploration technology company is 2.5 times stronger than it, but it is still difficult to return to the moon, and the reliability of the rocket is still high.

In the future, mankind will also establish a base on the moon, first as a scientific research base, then as a resource exploitation base, and then as a closed urban base on its surface for human migration. Although there is no air on the surface of the moon, the closed base can simulate the environment on the surface of the earth, or build underground cities under the surface of the moon, so the moon will also be the destination of 1 batch of interstellar immigrants.

When a base can be established on the moon, the era of human travel to the moon will officially begin. Of course, you have to have enough money, because going to the moon is expensive. According to the current space launch price, it is impossible to go to the moon without billions, because there are few rocket countries in the world that can launch manned spacecraft to the moon, and few rockets can be carried, so the safety of travelers must be guaranteed. From the production of rockets to the adjustment of flight, to the safe return and reception, thousands of people need to coordinate and cooperate. All kinds of measuring devices of the measuring ship and even many satellites in the sky have to serve this purpose, which consumes a lot of manpower, material resources and financial resources, and few people in the world can afford it.

Of course, everyone can also raise funds to travel to the moon together, which will cost less, but it will still be expensive to share. Even if the spaceship can take 10 people, everyone will have to pay hundreds of millions of dollars. Therefore, there is still a long way to go to popularize navigation to the moon. The general public wants to visit the moon during their holidays, but it is still difficult to achieve it in 100.
