The increasing involvement of private enterprise in the conduct of space activities raises key issues with respect to international space law which has left it to national law to implement relevant rules vis-a-vis private enterprise. Almost unavoidably, such national implementation regimes differ largely across individual states. This is also true in Europe, where the issue is further compounded by the fundamental - but fundamentally different - roles of ESA and the European Union. Focusing on Europe, the present book thus represents the first comprehensive effort to discuss national authorisation schemes not country by country but theme by theme, so as to allow for a real comparison of the lack of harmonisation or even coordination, and the possible problems which may result. ukryj opis
