As the "World Space Week" is being celebrated around the globe, we must not forget the vast contributions of the private space sector to the development of space travel, its innovation, and the expansion of its possibilities. In just a few decades, the sector has made the once off-limit dream of traveling to space possible for many, not only for astronauts and researchers working for the government. It has also reduced the price of space travel and significantly contributed to space mining. The private space sector has come a long way since its establishment, but the evolution has not been easy. Here, we explore some of the most significant milestones in the development of the private space sector.
