The space tourism and the border between airspace and outer space - the confrontation between functionalist and spatialist theories in this new world scenario

This study aims to discuss the application of functionalist and spatialist theories in the delimitation of space within the context of the private exploitation of space tourism. From a methodological point of view, the research is a literature review, based on the main authors in the field, and a documentary analysis, which relies on international documents, international treaties, and national legislation. The work is divided into three chapters: the first focuses on problematizing the boundaries between airspace and outer space; the second looks at functionalist theory; and the third is dedicated to spatialist theory.
