Air, Water, Food, Shelter, Sleep: These are the five basic requirements for a human being to survive. Providing these basics to a single person is a harrowing challenge; providing them to 1,200 souls on the merciless Martian landscape is nearly impossible. Nonetheless, in 2032 SpaceX successfully constructed Valinor – the first human scientific settlement on Mars-by transporting hundreds of scientists, engineers, scientific experiments and the most technologically advanced survival equipment ever created to the red planet. Each year saw more successful missions to Valinor, and the world community grew more excited about the realization of mankind’s expansion into the cosmos. However, after 15 years of exciting scientific discoveries and over 350 billion dollars invested in its survival and sustainability, Valinor remained monetarily profitless. After the stock market crash of 2047, SpaceX was purchased by OnlyEarth Corp., an oil conglomerate that saw Valinor as a threat to its fiscal security. Over the next three years, OnlyEarth reduced its regular supply missions to Valinor, demanding that Valinor produce massive quantities of Martian raw materials in exchange for fresh supplies from Earth. When Valinor refused to comply with these demands, OnlyEarth ended re-supply missions altogether. With the flow of corporate resources now stemmed, Valinor’s leadership was forced to redesign the sociopolitical and legal structure of its 1,200+ inhabitants to ensure the colony’s survival.

Registration is the sole basis for “jurisdiction and control” in outer space (Art. VIII OST) and also constitutes the basis for responsibility over a space object. It is therefore evident that ambiguities regarding registration are crucial for the safety of space operations. The discussion about registration has been escalating lately as space is becoming increasingly accessible with the diversification of space subjects. Simultaneously the practice of States indicates reduced diligence in registering their space objects. Initially, the present paper briefly recapitulates the different registries and processes based on the general rule that a launching State shall register a space object set by Art. II of the 1976 Registration Convention. It then turns to current challenges concerning the registration procedure as well as its consequences. Firstly, the term “launching State” is scrutinized, aiming to address several cases of private launches where registration was omitted. Subsequently, the challenges posed by the transfer of ownership of in-orbit space objects are discussed. In this context, it is examined whether there is a rule of international law allowing for the transfer of registration where the registering State has no effective control over an object. Secondly, the paper analyses the notion of “launching State” in light of joint launching and launchings realized by international organizations. It further attempts to answer the relevant question of registration of mega-constellations. The paper concludes by reviewing the possibility of the desirable harmonization and standardization of the registration regime under the Registration Convention, the UNGA Resolution 62/101 and the newly added Guideline 6 of the Guidelines for the Long-Term Sustainability of Outer Space Activities in light of the aforementioned developments.
