The recent development of “New Space”, i.e. a stronger involvement of private sector actors in all kinds of space activities make traffic rules in space necessary. Experts warn that without such rules the risk of collisions in the most interesting orbits would exponentially rise and eventually avoid future space activities due to space debris. Therefore, such a set of rules on Space Traffic Management is needed.

The Cologne Manual on STM will provide a comprehensive and well-structured proposal for a functional and sustainable system of STM. It will not limit itself to a strict character and seeks to aid the international law maker in forming soft or hard law instruments as well as the national legislators in providing example of how to regulate space traffic, in particular its interaction with air traffic on a national level. The Cologne Manual on STM will stand for a high scientific quality.
