In 2012, the International Academy of Astronautics (IAA) established a study group to report on status and trends in the Public/Private Human Access to Space, which leads naturally to focus on the probability of the emergence of a human orbital space market world-wide. This paper provides an introductory overview of the goals and analytical approaches implemented to conduct this study. Unlike analyses that approach similar topics from singular technical, financial or legal perspectives, this study group is pursuing a multi-disciplinary, multi-national and multi-cultural "holistic" approach to assess the probability of the emergence of human orbital space markets. After the initial phase of identifying the specific human orbital space markets being targeted and conducting a comprehensive literature review, the analysis will continue from the perspective of likely space-faring nations on a country-by-country (or region-by-region) basis to identify relevant political, legal, capital, historical and cultural factors and structures that support a human orbital market. This study will also identify the set of industries that comprise, support or are related to the identified target markets. Finally, this study will qualitatively evaluate the likelihood that these industry clusters are sufficient for the eventual natural evolution of human orbital space commercial markets.
