Space tourism creates profits that typical tourism cannot. Space tourism is quickly growing in popularity, even as a small subsector, thanks to the high-skill jobs it generates and the money it brings in. Such improvements will have a greater economic multiplier than other sectors. Therefore, exploring the demand for space tourism will have theoretical and practical significance. In this chapter, existing studies related to space tourism are identified and analyzed through literature research. There are not many articles exploring the demand for space tourism. This study reviews the literature-related journal on space tourism published from 2000 to 2023. It also attempts to identify the current focus and direction of research on space tourism demand and examines whether these articles use p-values and effect sizes correctly. This study concludes that the current articles on space tourism demand do not properly discuss effect sizes.
