Space Traffic Management, September 2005, Paris, France, 104 pages. At first glance, the management of space traffic does not appear to be a pressing problem. On closer examination, this judgement has to be challenged. A high level and ever growing number of launches from more and more launch sites and spaceports, the participation of non-governmental entities, the positioning of satellite constellations, an increase in space debris and the advent of reusable launch vehicles support this view. Conceptualizing space traffic management will turn out to become a relevant task during the next two decades. Space traffic management however, will limit the freedom of use of outer space. Therefore an international consensus on internationally binding regulations will only be achieved, if States identify certain urgency and expect a specific as well as collective benefit – including an economic benefit – from this. The study addresses or directs decision makers in UNCOPUOS, ITU and ICAO to approach specific problems, organizations which are building blocks for a future space traffic management regime.
