Why do humans want to explore space?

Why do humans want to explore space? Human beings have always had endless fantasies about space. It was not until the world's first rocket was successfully launched that people had an understanding of the universe. To this day, there are countless studies on space around the world, so why do humans go to space? What about exploration? Why humans want to explore space 1

First of all, because the earth where humans live is just a small planet in the vast universe, humans’ current understanding of space is like a child playing with sand on the beach understanding the sea. The understanding is the same. Humanity's desire for knowledge about space will be the eternal driving force for space exploration.

Undoubtedly, only through space exploration can humans finally answer the philosophical questions that have long puzzled mankind, such as "where did the universe come from" and "how did humans come into being".

Secondly, the purpose of space exploration is also to better protect and develop the earth. The earth is currently facing serious challenges such as climate warming, ecological destruction, energy depletion, and the possibility of asteroids hitting the earth. This forces us to consider whether humans need to immigrate to outer planets in the future.

It seems unrealistic to immigrate the entire human race. Even if the immigrants immigrate, it will only be a small number of people. Therefore, the only way to ensure the sustainable development of human society is to solve the ecological protection of the earth and the sustainability of energy. Utilize problems and develop and utilize space resources to continuously improve human life.

At present, using the high and distant location of space has achieved great results in the information fields such as communications, navigation, remote sensing, etc., and the development of material resources and energy has also begun to shine.

Finally, in the process of human space exploration, we will also abandon the human-centered concept of "man conquers nature", strive to protect the ecology of space, and achieve the ultimate goal of "harmony between man and nature".

Since man’s entry into space vividly reflects mankind’s pursuit of breaking through the limitations of the earth, manned spaceflight has been recognized from the beginning as a clear manifestation of comprehensive national strength, triggering conflicts between the United States and the Soviet Union. 30 years of space race.

Facts have proved that successful manned space activities will greatly enhance national prestige and stimulate national pride and cohesion. However, the Cold War mentality of this big country also leads to low cost-effectiveness of manned space activities. and difficulty in sustainable development. Currently, world space activities have begun to enter a major transformation period.

In addition to considering improving national prestige, the aerospace activities of various countries pay more attention to practical results and strive to achieve the greatest comprehensive political, economic, scientific and technological benefits from aerospace development.

To this end, all countries are focusing on the development of space launch technology and applied satellite technology, actively developing manned space technology and detection technology for the moon, asteroids and Mars, and have begun Explore the possibility of harnessing solar energy from space.

Judging from the historical facts of manned spaceflight, manned flight can not only improve the performance of aerospace vehicles due to their fine observation and operation capabilities, their ability to respond to abnormal events in a timely manner, and their creative judgment, analysis and decision-making abilities. operational reliability and can improve the efficiency of space operations and maintenance.

However, when people enter space in person, they always take great risks and pay a high price. Therefore, all tasks that can be completed without human participation must be completed by unmanned spacecraft, and only those tasks that must be completed by humans can be completed by astronauts.

The combination of humans and automated systems (robots) will be the only way for future space exploration. This is not only to save money, but also to cherish the lives of astronauts.

The cost of space transportation and spacecraft remains high, which has become a bottleneck for large-scale utilization of space resources. In an environment subject to financial constraints, the world's aerospace powers are working hard on technological innovation on the one hand, and on the other hand they are beginning to combine state behavior with the market economy.

The United States is vigorously supporting private enterprises in the development of low earth orbit, and has achieved initial results in technological innovation and cost reduction.

Looking into the future, major aerospace countries will continue to regard space as the commanding heights of competition for comprehensive national strength. However, on the basis of improving the international competitiveness of their own aerospace industries, countries will, in order to save investment and accelerate develop and reduce risks, and begin to strengthen international cooperation in the field of civil aerospace.

Space exploration has always been a common cause for mankind, and international cooperation must be the general trend. At present, Western countries have blocked China's aerospace technology to varying degrees out of prejudice. I believe that as our country's aerospace capabilities improve, we will definitely break through this resistance.

In terms of space exploration, mankind has only taken the first step in a long journey of thousands of miles. In terms of the goals and methods of exploration, space exploration will never end. Why humans want to explore space 2

1. Humanity’s desire for knowledge in space will be the eternal driving force for space exploration.

Only through space exploration can humans finally answer the philosophical questions that have long puzzled mankind, such as "Where did the universe come from?" "How did humans come into being?"

2. The purpose of space exploration is also to better protect and develop the earth. The only way to achieve sustainable development of human society is to solve the problems of ecological protection of the earth and sustainable use of energy, and to develop and utilize space resources to continuously improve human life.

Space tourism

Space tourism is based on people’s ideal of traveling in space. Traveling to space provides people with an unprecedented experience, the most novel and The most exciting thing is that you can enjoy the beautiful scenery of space and enjoy the taste of weightlessness. These two experiences can only be enjoyed in space.

The space tourism project began on April 30, 2001. The first space tourist was American businessman Dennis Tito, the second was South African tycoon Mark Shuttleworth, and the third was American Gregory Olson. Nie Haisheng is one of them. Why humans want to explore space 3

First of all, we can look at the development of human civilization. The earliest human social civilization appeared thousands of years ago. It took humans a short time to create brilliant achievements. Civilization and science are the original driving forces that promote the development of human civilization. It is the gradual progress of science that frees mankind from ignorance and looks at the world from a more correct and comprehensive perspective.

Science is an ordered knowledge system based on testable explanations and predictions of the form and organization of objective things. It is knowledge that has been systematized and formulated.

So, how did science rise step by step? The answer is actually very simple. "Exploring the unknown" is the essence of scientific development. Only through continuous exploration can we discover new knowledge, summarize the problems encountered, and find the best answers, which is the essence of human science.

Although there are still many unknowns on the earth, there are also many areas that are uninhabited, especially in the oceans. There are many unexplored areas that may be hidden in these areas. There are many magical creatures, but for human civilization living on the earth, the space of the earth is always limited, and the limited space cannot accommodate an infinite population.

The development of human science has promoted the continuous increase in the average life span of human beings as a whole. Overall, the global population will inevitably continue to increase. Although the earth is large, it cannot accommodate so many humans because the population The increase will also increase the changes in the earth's environment

Scientists believe that after the human industrial revolution, the earth's overall climate has obviously changed a lot, the average temperature continues to rise, and the melting of the polar glaciers will cause global Sexual chain reaction.

What should we do if the earth's environment changes greatly and is no longer suitable for human survival? Perhaps the best solution is to immigrate to other planets. Currently, various countries on the earth are actively exploring Mars. This is because Mars may be the most suitable planet for human immigration.

First of all, Mars The distance is close enough, so there is no need to worry about the energy and material supplies required for long-distance interstellar travel. If any accident occurs on Mars, humans can also provide relatively quick support.

This is the most important reason for human beings to explore the universe. Faced with various possible accidents, human beings cannot put their eggs in one basket. We need to preserve the fire of civilization and science.

The great physicist Hawking also reminded us many times that "if human civilization wants to continue for a long time, it must immigrate to other planets." This is Hawking's advice to mankind. We can learn from this great scientist His concern for human civilization can be seen in his advice.

The reason why humans must explore the universe is very realistic and also scary. The earth cannot be the home of humans forever. First of all, in a short period of time, the earth’s environment may not be the same. Any changes

However, judging from the history of geological changes of the earth, the overall climate of the earth is not absolutely stable. It shows great fluctuations over time. Compared with the history of the earth, the time when human civilization appeared In a very short period of time, we have not experienced relatively large climate changes or huge disasters that the earth may encounter.

The current danger closest to humans may be the eruption of the "Yellowstone Volcano". Scientists believe that the Yellowstone Volcano has entered an eruption cycle. If the Yellowstone Volcano erupts, it is likely to cause a global disaster. Secondly, the Sun Activities may also have an impact on humans

These disasters are very far away for current humans, but once they occur, they will cause great harm. This is one of the reasons why humans must explore the universe. In the face of such possible disasters, human beings cannot be "annihilated".

In addition to these reasons, there is also a more realistic reason. If human physics wants to go further, it must continue to explore the universe. Only by constantly exploring the unknown, after summing up experience Human science can continue to develop. If we only stay on the earth, our science will be in trouble after it develops to a certain extent.
