The Outer Space Treaty (OST) was signed on January 27, 1967 as a binding legal instrument. Over the years this treaty has largely ensured responsible conduct of space activities. This book attempts to examine and contextualize the treaty and its relevance in the 21st century while tracing its journey over the last fifty years.

This publication sets out the text of the five UN treaties so far adopted governing the activities of countries in the exploration and use of outer space, as well as the five Principles adopted by the UN General Assembly.

This book is based on the findings, conclusions and recommendations of the Global Space Governance study commissioned by the 2014 Montreal Declaration that called upon civil society, academics, governments, the private sector, and other stakeholders to undertake an international interdisciplinary study. The study took three years to complete. It examines the drivers of space regulations and standards, key regulatory problems, and especially addresses possible improvements in global space governance. The world's leading experts led the drafting of chapters, with input from academics and knowledgeable professionals in the public and private sectors, intergovernmental organizations, and nongovernmental organizations from all the regions of the world with over 80 total participants. This book and areas identified for priority action are to be presented to the UN Committee on the Peaceful Uses of Outer Space and it is hoped will be considered directly or indirectly at the UNISPACE+50 event in Vienna, Austria, in 2018. The report, a collective work of all the contributors, includes objective analysis and frank statements expressed without pressure of political, national, and occupational concerns or interest. It is peer-reviewed and carefully edited to ensure its accuracy, preciseness, and readability. It is expected that the study and derivative recommendations will form the basis for deliberations and decisions at international conferences and meetings around the world on the theme of global space governance. This will hopefully include future discussion at the UN Committee on the Peaceful Uses of Outer Space.

The opening of space to exploration and use has had profound effects on society. Remote sensing by satellite has improved meteorology, land use and the monitoring of the environment. Satellite television immediately informs us visually of events in formerly remote locations, as well as providing many entertainment channels. World telecommunication facilities have been revolutionised. Global positioning has improved transport. This book examines the varied elements of public law that lie behind and regulate the use of space. It also makes suggestions for the development and improvement of the law, particularly as private enterprise plays an increasing role in space.

It is a remarkable achievement to write a book that almost four decades after its publication has lost virtually none of its relevance. Manfred Lachs’ famous treatise on the Law of Outer Space was originally published in 1972, yet it is still a classic and must-read text for space law students today, even though copies can nowadays be rarely found. The reissue of this remarkable work is therefore timely indeed. Its aim is to make the brilliance, foresight and clarity of Lachs’ thinking once more easily accessible to a new generation of scholars. Issued on the occasion of the 50th anniversary of the International Institute of Space Law, of which Lachs was President, this volume reproduces the original text of Lachs' work in full, with a new preface, introduction and index supplied by the editors.

The relevance and substance of space law as a branch of public international law continues to expand. The fourth edition of this long-time classic in the field of space law has been substantially rewritten to reflect new developments in space law and technology of the past ten years. This updated text includes new or expanded material on the proliferation of non-state and commercial entities as space actors, the appearance of innovations in space technology, the evolving international law of satellite telecommunications in a networked world, and the adoption of national laws and international soft law mechanisms that complement the international treaty regime. In this up-to-date overview of space law, the authors offer a clear analysis of the legal challenges that play a role in new and traditional areas of space activity, including the following: - the peaceful uses of outer space; - protection of the space environment; - the emergence of new legal mechanisms in space law; - the role of Europe in space; - telecommunications; - the commercial use of space resources; - human space flight; - small satellites; - remote sensing; and - global navigation satellite systems. Additionally, the five United Nations Treaties on space are included as Annexes for easy reference by students and professionals alike. In light of the many new developments in the field, this thoroughly updated Introduction to Space Law provides a clear overview of the legal aspects of a wide array of current and emerging space activities. Lawyers, policy-makers, diplomats, students, and professionals in the telecommunication and aerospace sectors, with or without a legal background, will find concise yet comprehensive guidance in this book that will help them understand and address legal issues in the ever-changing field of space activities. The authors are close former collaborators of the late pioneers of space law and authors of the earlier editions of this volume, Isabella Diederiks-Verschoor and Vladimír Kopal.

Impacts by asteroids or comets on Earth may lead to natural disasters of catastrophic dimensions. This book addresses legal and policy aspects of ‘planetary defence’ activities by space agencies and other actors aiming at the prediction and mitigation of Near-Earth Objects (NEOs).
