Remember the huge revolving space station in the movie The Wandering Earth? The shape of the space hotel will also be a huge ring, which is connected by a series of pods outside the ring. The artificial gravity produced by rotation is similar to the gravity level on the surface of the moon, and it rotates around the earth once every 90 minutes. Some of these pods can be sold to the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) for space research.
In today's world, tourism is an important part of modern civilized society, and it is also an important symbol of whether modern society is full of vitality. This is also one of the important means for many countries to earn foreign exchange and prosper their economies. From 65438 to 0980, countries all over the world earned $96 billion in economic income from tourism alone. Therefore, countries actively develop tourism resources according to their own characteristics, take all effective measures to attract tourists, and vigorously develop their own tourism. It can be imagined that with the appearance of various high-speed and cheap spacecraft, especially after the birth of Space City, space tourism will undoubtedly become an important part of space industrialization.
It should be pointed out that the key to developing space tourism is to develop more advanced and cheaper space transportation systems and space cities. According to the ideas of space experts and advocates of space colonization, whether it is to develop a more advanced space transportation system or to build a long-awaited space city, it is possible to become a reality at the beginning of this century. By then, the universe that mankind yearns for will no longer be the hereditary territory of professional astronauts, but will become a paradise for all mankind.
In other words, anyone who is healthy is qualified to travel in space. Of course, space tourists will include all kinds of people. Some are natural scientists who go to space to engage in scientific research, and some are writers, artists and journalists. They go to space to embody life, some heads of government go to Space City, and some go to Space City. Businessmen from various countries discuss trade business.
Of course, ordinary tourists who want to share the fun of space travel can also get their wish, but they wait in line and wait patiently. Perhaps geologists and explorers have the best hope to land on the moon and reach other planets in the solar system, and start with fact-finding missions and exploration missions to asteroids. Although space tourists have different purposes, Space City is a must-see attraction, which opens up broad prospects for vigorously developing space city tourism.
O 'Neill, a professor at Princeton University in the United States and the most active advocate of space colonization, optimistically pointed out that by 20081year, when predicting the development prospect of human society in the future 100, there will be a person with a driving distance of 500 kilometers per second. There will be many space cities in the solar system, especially in the asteroid belt between Jupiter and Mars. By then,? 200 million people will travel between the earth and space every year? . If his prediction can be realized, then space tourism will have an inestimable impact on the future economic development and social prosperity of space!
