  This paper describes a repository for ontologies of astronomy, astronautics,
and other space-related topics. It may be called AstroPortal (or SpacePortal),
AstroHub (or SpaceHub), etc. The creation of this repository will be applicable
to academic, research and other data-intensive sectors. It is relevant for
space sciences (including astronomy), Earth science, and astronautics
(spaceflight), among other data-intensive disciplines. The repository should
provide a centralized platform to search, review and create ontologies for
astro-related topics. It thereby can decrease research time, while also
providing a user-friendly means to study and compare knowledge organization
systems or semantic resources of the target domains. With no apparent
repository available on the target domain, this paper also expresses a novel
concept.
