The Significance of Obtaining Earth-Moon Data for Human Beings

The Significance of Obtaining Earth-Moon Data for Human Beings

The moon is full of mystery and beautiful in our eyes, and we human beings give the moon a lot of meaning, because its existence is really important. Let's take a look at the significance of the acquisition of earth-moon data to human beings.

The significance of the acquisition of earth-moon data to human beings 1 The moon is the best platform for human beings to study the universe and the earth itself. The scientific community believes that studying the moon under these superior conditions without artificial transformation and destruction is helpful to understand the ancient state of the earth, the origin and evolution of the solar system and even the whole universe.

It is helpful to understand the relationship between space phenomena and natural phenomena on earth, and can greatly enrich people's understanding of the origin and evolution of the earth, the solar system and even the whole universe and its characteristics, and seek clues about the origin and evolution of life on earth.

An important carrier to promote the progress and development of science and technology, developing the moon is an unprecedented arduous undertaking, and a series of problems need to be solved, which will inevitably lead to the rapid development of high-thrust rockets, giant spacecraft, high-speed flight, artificial intelligence, computers, robots, processing automation, precision instruments, remote sensing operations, communications, materials, architecture, energy and other engineering technologies and space biology, space physics, space astronomy and other science and technology.

Prepare for the development and utilization of lunar resources

According to previous exploration, moon rocks contain all the material elements in the earth's crust, and there are about 60 kinds of mineral deposits. Moon rocks and soil are rich in oxygen, iron, magnesium, calcium, silicon, titanium, sodium, potassium, manganese and other substances. In addition, there are abundant energy sources on the moon, especially helium -3 on the moon, which is an efficient fuel for nuclear fusion reaction that is not found on the earth. It is estimated that the total amount of helium -3 resources in lunar soil can reach 6.5438+0 million to 5 million tons, which can support the power demand of the earth in 7000 years.

Promote deep space exploration

The gravity on the surface of the moon is only 1/6 of that on the surface of the earth. If the spaceship takes off from the moon, it can save energy greatly. Moonrock soil contains 40% oxygen, which can be used for local production of propellant and as an oxygen source for controlled ecological environment and life support system. Silicon accounts for 20%, which can be used to make solar array of spacecraft; Other metals can be used to make various components and equipment of spacecraft, and the moon can also be used as a transit station to repair and refuel the passing spacecraft.

A platform for astronomical observation and research

The geological structure on the surface of the moon is extremely stable. The moon bears the radiation of the sun directly, and there is no interference from the absorption, scattering and refraction of light and radio waves by the atmosphere, no dust pollution, no magnetic field and no artificial light source and radio interference on the back of the moon. The earthquake is very small. At the same time, the night on the moon is very long and the temperature at night is extremely low. This environment provides an ideal place for building a high-precision observatory.

boost the economic development

Developing the moon can bring immeasurable economic benefits, and the secondary development and application of other technologies will inevitably promote the development and upgrading of the industry.

Luan Enjie, the commander-in-chief of China's lunar exploration project, made an incisive and scientific exposition. He explained the exploration, development and utilization of the moon in three steps. It can be simply summed up in three words, namely, "explore, board and live". "Exploration" means exploring the moon. We must first understand the unknown moon and explore the necessary information.

"Landing" means landing on the moon. Humans can land on the moon, get close to the moon resources and return safely. "Stationing" means that equipment or human beings can be stationed on the moon for a short or long time to realize their dream of developing or living on the moon resources. Among them, "exploring the moon" can be divided into three periods, namely "circling the moon", "falling the moon" and "returning to the moon".

The first stage of "orbiting the moon" is to launch a satellite orbiting the moon and carry out scientific exploration in the polar orbit of the moon at a height of 200 kilometers from the surface of the moon; The second stage of "landing" is to choose a suitable place to land on the surface of the moon and explore with the lunar rover; The third stage of "return" is to collect some samples and return to Earth.

The moon is an ideal place to study astronomy, space science, earth science, remote sensing science, life science and materials science.

We have reason to believe that the successful exploration of the moon by Chang 'e 1 satellite is only the first step for China to explore deep space. With the development of lunar exploration, it will help people to study the origin and evolution of the moon, the earth and the solar system, especially some basic problems in lunar science.

For example, the formation process of the moon, the early evolution history of the moon, the formation and distribution characteristics of lunar minerals, the formation and evolution of earth-moon system, the comparative study of the moon, the earth and terrestrial planets, and their respective characteristics and characteristics. Only through a new round of exploration can we gain a more systematic and in-depth understanding.

The significance of obtaining the data of the Earth and the Moon is 2 1. The moon is rich in mineral resources, and people need a lot of mineral metals to make so many things. We have used up all the iron and copper in other areas. Let's go to the moon to find it. Only in this way can people live better.

2. Migrants from alternative homes, if the population exceeds the carrying capacity of the earth, can only go to the moon or build a space city or something. Relatively speaking, it is more feasible to build a big city on the moon. After all, there is enough space, what's more, if something happens to the earth, the moon is Noah's Ark!

3. Provide energy: establish an energy base.

4. Explore space as the frontier base of the wider universe. It is much easier to launch Mars in that rocket launching area than on the ground, with small gravity and air resistance, which is quite economical. Why explore space? The reason is the same as the first point.

5. Travel to satisfy human curiosity, and so on.

The significance of obtaining the data of the earth and the moon to human beings. The influence of the moon on the earth and human beings.

tidal action

The tidal action of the earth's oceans is the action of the moon's gravity and the sun's gravity. The rotation, revolution and period of revolution of the moon, the earth and the sun are periodic, so humans can predict the specific time of ocean tides. Tides can be divided into spring tides and small tides; The spring tide is a spring tide in which the local moon, the sun or the moon, the earth and the sun are connected by three satellites and the gravity of the sun and the moon works together. When the connection between the sun and the earth is at right angles to the connection between the moon and the earth, the tidal force of the sun and the moon will cancel each other out, which is a small tide.

Humans don't just enjoy the spectacular tides once a year on the fifteenth day of the eighth lunar month. More importantly, tidal energy can be used to generate electricity. At present, more than ten tidal power stations have been built in China, and the Jiangxia tidal power station built in 1980 can generate1070,000 kwh per year. Tidal power stations bring many benefits because they neither waste energy nor pollute the environment.

Tidal phenomena will also profoundly affect the reproduction of marine life. Fish in the sea can lay eggs in shallow beaches through tidal action, and tides will also affect the distribution environment of plankton. Some aquatic organisms living in the intertidal zone can adjust their activities to adapt to the tides through their own physiological clocks, because the origin of life may come from the ocean, so the role of the moon can be imagined.

The basis of compiling a calendar

People have fortunes at any time, and the moon is full of rain or shine. People in ancient times observed the moon very early, and used the changes of the moon to compile calendars. The new moon is the first day and the full moon is the fifteenth.

People in ancient China lived and produced according to this calendar. Now the traditional festivals of China people are also based on the lunar calendar. When the moon is full, it is endowed with the beautiful meaning of reunion!

Space springboard

Although the conditions of the moon are relatively bad, it is also the first planet that humans can board. In the future, with the progress of science and technology, mankind will build a sky probe launching station on the moon.

Why are you doing this? The main reason is that the gravity of the moon is only one sixth of that of the earth. Launching a space probe from the moon is very cheap.

Utilization of lunar resources

With the development of human science and technology, the distance between the moon and the earth may not be "distant" in the future, and the moon may bump into the earth, so the moon may be rich in some metal minerals rich in the deep layer of the earth, and that country may give priority to the right to use the moon resources. With the gradual decrease of earth resources, space resources will be a good choice in the future.
