Why is Musk obsessed with going to Mars? What's the real reason behind this?

Currently, various countries are exploring space beyond the earth in order to find the origin of life on earth. With the development of science and technology, humans have never been able to pry into the mysteries of the origin of life on earth, so countries around the world are exploring outer space.

Elon Musk graduated from the University of Pennsylvania with a double degree in economics and physics. He is currently CEO and CTO of Space Exploration Technology Company, CEO of Tesla Company, and Chairman of the Board of Directors of Solar City Company. At 5:45 pm Eastern Time on December 9, the Starship SN8 prototype was launched from the SpaceX launch platform near a village in southern Texas. Although the launch failed. However, the launch team has obtained all the data it needs and is confident that SpaceX will launch its first manned mission to Mars in 2026.

As a billionaire, why are we so obsessed with going to Mars? I think the real reason behind it is to fulfill his personal dream. Musk believes that humans should become an interplanetary species. Mainly because Mars is relatively close to the Earth, and Mars once had surface oceans and rivers. Although they have evaporated and dried up, there are still ice and underground lakes, and the surface temperature range of Mars is not far different from that of the Earth. These factors, They all illustrate that through relevant technologies, people can live and live on Mars.

Dreams are more beautiful, but reality is more cruel. First, the Martian environment is relatively harsh. The atmosphere around Mars is too thin and the temperature is relatively low to accommodate the existence of liquid water, and there is not enough carbon dioxide on Mars to provide a warming greenhouse effect, so the climate conditions cannot be achieved. The second is the current technical limitations. Martian soil contains large amounts of perchlorate, which is toxic to the human body and crops cannot survive at all. It must be cleaned if it is to survive, but current technology cannot achieve it.
