The Project

The Cologne Commentary on Space Law (CoCoSL) comprises a three-volume, provision-by-provision Commentary on the five United Nations treaties on outer space and the five major UN General Assembly Resolutions. The CoCoSL project was launched in January 2007, marking the fiftieth anniversary of space flight as well as the fortieth anniversary of international outer space legislation. Between 2009 and 2015, its three volumes were published by the Carl Heymanns Publishing House. Since 2017, spin-off translation projects have resulted in an English-Russian and an English-Chinese translation of Volume I and in an English-Russian translation of Volume II. The Russian translations are also available as E-Books.

As a joint undertaking of the Institute of Air and Space Law of the University of Cologne and the German Aerospace Center (DLR), the commentary brings together the scientific and academic proficiency of the Institute and the practical and technical capacity of DLR. It provides a critical analysis of the evolution of the written norms of space law, current developments in the field, relevant State practice, and perspectives for the future. With this, the Cologne Commentary on Space Law constitutes essential reading for all academics, practitioners and technicians working in the field of space law and beyond.

Volume I of CoCoSL provides an Article-by-Article commentary on the 1967 Outer Space Treaty. Contributing authors were especially urged to elaborate on the current issues in the field, as well as the practical applicability of the law at present and in the future. Volume I of CoCoSL was published in 2009.

Volumes II and III respectively comment upon the other four United Nations Treaties on Outer Space, and the relevant United Nations General Assembly Resolutions.
