Increased density of space traffic is driving reflections on regulatory frameworks. Space Traffic Management (STM) is one of the emerging ideas, but also implementation of the Cape Town convention on space assets is presently discussed. UNIDROIT has taken the initiative to propose a legal framework for space assets in accordance with the latter convention. Although the principle has been welcomed by many parties, in particular the space operators have expressed individual reservations. The purpose of this study was to seek for a common view on such reservations on the basis of a questionnaire. In view of the highly specialised topic, a well-distributed but restricted group of respondents was approached with this questionnaire. Although statistically this leads to a rather limited database, on the other hand it guarantees well-informed feedback.
