Who is Addressing the Deficiency in the Literature on the Prosperous Development of Outer Space? : A comparative approach to the interconnected issue of the absence of a space power theory, and the controversy surrounding the definition and delimitation o

Abstract: As outer space becomes more commercialized, humans have invested more time and efforts into the use and exploration of the outer space domain. Captured by the display of opportunities, space is becoming increasingly overcrowded. Currently, the only framework fully embracing the exploration and use of outer space is the Outer Space Treaty (OST), put forward by the United Nations in 1967. While the OST is detailing how space faring nations ought to peacefully use outer space as a joint arena for technological development, the discourse on outer space governance still experience some serious definitional limitations. This paper examines two interconnected deficiencies in the literature on outer space; first, the insufficient research and development of a space power theory and; second, the absence of, and the challenges in constructing and all- encompassing definition and/or delimitation of outer space. To support the discussion and to reach some definitive conclusions of the current status of these issues, a selection of historical theories and contemporary cases have been applied to enrich the debate. By identifying gaps in the literature, this paper strives to highlight some of the controversies in the outer space discourse.
