Can people live on the moon?

In order to develop the moon, it is necessary to build a lunar base for people to live and work. Not long ago, NASA put forward a plan to return to the moon in 20 10 and set up a base there that can accommodate 100 people. This base is wheel-shaped or cylindrical with a diameter of 1-2km. There are mountains, rivers, lakes, forests and many creatures in it. It is a self-sufficient and dynamic closed ecosystem. The whole project will cost 6,543.8 trillion US dollars. Japan, Russia and western European countries are also ambitious and unwilling to lag behind.

According to the plans announced by the United States, Japan and other countries, the development of the moon can be roughly divided into the following five stages:

From this century to the beginning of the next century is the first stage, also known as the unmanned stage. The main work is to use control tools or robots to investigate the lunar terrain, select the site for the base and draw the distribution map of lunar resources.

Since 2005, it has been the second stage, also known as the short-term detention stage. A few researchers will be sent to the moon to work irregularly for a few days to weeks. The first thing they should do is to establish a geological and geographical research institute, start measuring the contents of iron, aluminum and helium in lunar rocks, and make experimental applications to various processing devices. At this stage, the oxygen, food, water, daily necessities and building materials needed by the moon landing personnel will be sent from the earth to the moon by rocket.

From 20 10, it enters the third stage, which is usually called the fixed residence stage. At this time, the base will expand and the number of personnel will increase. Dozens of workers may have to work on the moon for several months because of the facilities that can prevent strong solar radiation and the establishment of a closed ecosystem. They will start a whole set of equipment, start making oxygen, refining water and smelting metals, and study how to transport the moon's resources back to Earth. At the same time, the observatory will be built.

10 year, that is, from 2020, it will enter the fourth stage, which is usually called the permanent residence stage. At this time, the number of staff will increase to hundreds. They will build lunar farms and factories, and develop the technology of extracting helium 3 by microwave irradiation to solve the energy supply problem and send the excess energy back to the earth.

The fifth stage from 2030 is the immigration stage. At this time, the inhabitants of the moon will be completely self-sufficient. There are regular round-trip routes between the moon and the earth, as well as space hotels for people to rest and entertain. It will fly around the earth and rotate every 3 minutes to prevent passengers from shaking in the guest room. At this time, people will pave the way, rectify the traffic and build one brand-new moon city after another. Although it was a moon city, there were only a few hundred residents at that time. Until 2 1 century, there will probably be a moon city inhabited by millions of people.
