This thesis aims to study the implications of the existing framework of international space law and public international law on space debris remediation. Following a description of the hypothesis and the research methodology, the introductory chapter explains the current state of the debris environment and the consequent need to perform space debris remediation. With that understanding, the economic and technological feasibility for such an endeavour is also assessed. The second chapter addresses the concerns regarding the current definition of a ‗space object‘ and examines the requirement for the adoption of a separate legal definition of space debris to facilitate space debris remediation activities. The key question of legitimate exercise of jurisdiction and control over space objects, in the realm of space debris remediation, along with contentious issues such as transfer of ownership and/or registry of space objects are discussed in the third chapter. The fourth chapter elaborates on the related responsibility and liability considerations linked to remediation activities in outer space. The final chapter contains a summary of the important conclusions from the earlier chapters and presents some overall observations on the entire analysis. Legal Aspects of Space Debris Remediation Page ix ___________________________________________________ Résumé ___________________________________________________ Avec la prolifération alarmante du nombre de débris orbitaux, des études scientifiques ont montré la nécessité d‘effectuer un nettoyage des débris spatiaux, par le biais de la suppression effective de ces débris ainsi que la mise en place d‘un système orbital de « service » aux satellites. Cette thèse vise à étudier les effets du cadre actuel du droit spatial international et du droit international public, sur la gestion du problème des débris spatiaux. Après une description du postulat et de la méthodologie de recherche, le chapitre introductif (chapitre I) explique l'état actuel de l'environnement des débris spatiaux et la nécessité d‘éliminer ces débris. Dans ce contexte, la faisabilité économique et technique d'une telle entreprise est évaluée au chapitre II. Le chapitre III traite des questions liées à la définition actuelle d'«objet spatial» et examine les conditions de l'adoption d'une définition juridique distincte pour les débris spatiaux, afin de faciliter les activités de nettoyage afférentes. La question essentielle de l'exercice légitime de la juridiction et du contrôle des objets spatiaux, s‘agissant de leur nettoyage, ainsi que les sujets controversés tels que le transfert de propriété et/ou l‘enregistrement des objets spatiaux, sont examinés dans le chapitre IV. Le chapitre V entre dans le détail des réflexions sur la responsabilité liée aux activités de dépollution dans l'espace. La section finale (chapitre VI) comprend un résumé des conclusions importantes des chapitres précédents, et présente quelques observations générales sur toute l'analyse.
