Business in space

It sounds like science fiction, but man really is exploring and conquering space. 

​

Space has been privatized and businesses in space already move 330 billion dollars and this number will continue to grow and today there is already a large number of companies exploring this niche. They are from the pharmaceutical area, tourism, mining, among others. But of course, we cannot fail to mention space transportation, so popularized by Elon Musk and his Space X, as well as the conquest of Mars as an alternative housing for the human race in the future.
