When considering the planetary migration of the human race to other terrestrial planets within our Solar System, it is crucially important to survey what kind of resources can be established for a self-sufficient system. This system cannot depend upon planet Earth to secure food, clothing, or construction materials, to sustain a “space society” on each planet. In this study, we proposed three essential “core” concepts for space migration, consisting of a “Core biome”, “Core Technology” and “Core Society. The life-support system and the global ecosystem are a "core biome complex", and the technical system necessary for maintaining a life system is "core technology". A "core society" is the minimum circular society in the space migration concept, with the minimum necessary important systems that do not depend on other ecosystems. We use these to scrutinize and examine the realization of a "space society". In particular, in order to sustainably maintain the "core biome complex" existing on Earth for a long period of time, it is important to establish a system that is not overly dependent on other systems. The above concept has been established based on the necessity that terrestrial creatures like us can establish an “Earth-like” environment on different planetary bodies. However, changing the entire planetary environment requires a huge amount of energy and technology, which may not be realistic to put into practice for a few years. We also propose the concept of “Terrawindows”, bringing an Earth-like shelter environment to establish on other planetary surfaces in order to follow planetary defense which is different than “Terraforming” which transforms the entire planet into an Earth-like environment.
