This book assesses the present status of space activity regulation against the background of the progressive commercialization of outer space. The basic legal framework for outer space activity was established during a time when space endeavour was still in its infancy and a critical reassessment of its principles therefore forms the basis of this publication. The outcome of this analysis and the legal implications which result from applying it to practical space utilization yield an insight into the legal questions pertaining to space commercialization and its practical implementation. "Commercial Utilization of Outer Space" will be of great interest to academics and practitioners in the field of space activities, as well as to government policy makers in different sectors of space commercialization ranging from space transportation, satellite communication and remote sensing to space insurance and manufacturing in outer space. Wherever appropriate and feasible practical aspects have been dealt with against the background of present-day realities and developments foreseen for the future.
