Ad Astra is developing continuously. Why do people want to explore the planet where people can live?

With the increasing strength of scientific and technological research and development, scientific and technological talents emerge one after another all over the world, which can be said that the "post-wave" has really risen. People's thoughts keep pace with the times, and they are more curious about the unknown face of the universe. Every country has invested a lot in the field of space exploration. From the first astronaut landing on the moon to the fact that many satellite probes are standing in the universe today, it shows the determination of human beings to explore the universe. Although the current science and technology is not perfect, it can only explore the tip of the iceberg of the universe, so many people are puzzled. Humans have landed on the moon and explored Mars. Since the level of science and technology is not yet mature, why should we explore the universe frequently? If once an alien civilization is discovered, is it good or bad for human beings?

Although these fears are unreasonable, scientists believe that exploring the universe will cost a lot, and perhaps a small part is a crucial turning point. Exploring the universe can not only make up for the lack of scientific and technological development, but also prevent the crisis in advance and deal with it in time to a certain extent.

Space exploration can improve the research and development of science and technology.

Astronauts will train around the clock before going into space. Even after going into the universe, they will face many unknown situations. Therefore, scientists have also invented many products to help astronauts avoid unknown dangers as much as possible. For example, the space carpet, which we are all familiar with, has penetrated into our lives, but it was invented by a scientist of NASA. In addition to the space blanket, the invention of Nitinol has also brought convenience to human life, and now it has become an important material for dental appliances.

monitor the trajectory of asteroids.

Some time ago, an asteroid was discovered in the United States, which almost collided with the Earth during its movement. Scientists have predicted the fate of this asteroid in advance through satellite monitoring, and it will not hit the Earth. Therefore, this news did not cause human panic. All the stars in the universe are in constant motion. If human beings do not take precautions before the meteorite falls, it will be a fatal blow to human beings. What should human beings do then?
