Space, once the exclusive preserve of developed countries' space agencies, has become a field of activity for numerous new actors, including startups, thanks to decreasing costs. The decline in production and launch costs, particularly for small, low-orbit satellites, has paved the way for many companies to acquire their own satellites to meet their own needs. From the telecommunications sector to the agricultural sector, many companies are working to gradually transition their communications infrastructure to space. In addition to reusable launch rockets, high-altitude aircraft and UAVs are expected to further reduce launch costs in the future. The number of new business models created through the use of satellites is increasing daily.
