The colonization of space, as an idea, is expressed over time through science fiction in literature, cinema and television. At the same time, this issue is addressed by relevant scientific research and studies. The possibility that the Earth will no longer be habitable in the distant future, due to natural or artificial causes, has made the colonization of space seem like a goal, almost, necessary.

The space station is the first structure that can support the prolonged stay of man in space. Since the 1970s, a large number of such stations have been sent into orbit around Earth. These stations have allowedto a limited number of people to remain in space and have contributed to the extensive research of the universe. Many scientists, through their research, aim to build larger structures of this kind, so that they can be formed into colonies, with the possibility of permanent human life in space and their complete independence from Earth.

In science fiction, and especially in cinema, the evolution in the form of the space station is projected, from simple structures to more complex ones, either imaginary or science-inspired, serving a variety of functions (transit stations, research centers, living spaces, etc.). Out of all these films, the research study comment on five of them [Cargo (2009), Elysium (2013), Interstellar (2014) Star Trek Beyond (2016), Valerian and the City of a Thousand Planets (2017)], in which the space station emerges as a future autonomous city, capable of accommodating thousands to millions of settlers. In particular, a detailed description is given of the formation of the urban landscape and the architectural design of the extra-terrestrial cities, in which the plot of these films takes place.

In the fictional world of each film, the representation of the city offers “a significant and visibly signifying shape and temporal dimension” (Sobchack, 2004), gives character to the protagonists and their culture, showing the way they have chosen to live.
