Why do humans go to space?

The vast universe is boundless, and the earth where human beings live is just a drop in the ocean. Human beings know little about the universe, so they also arouse their desire to explore the universe.

The earth's resources are not endless, and will be exhausted one day. In addition, with the influence of human activities, the ecological environment of the earth is facing a severe test, which forces us to consider whether human beings will immigrate to other planets in the future.

There are many resources available to human beings in space. Exploring space can find new energy sources and develop new technologies, and it is also to better protect and develop the earth.
