The field of space, once exclusive to specialized experts, is becoming democratized, ushering in an era where everyone can engage with it personally. In this context, the creation of new knowledge through interdisciplinary collaboration is in demand. To address this challenge, we will form a co-creation team comprising corporations, universities, municipalities, research institutions, small factories, startups, investors, and the next generation of children. Together, as fellow inhabitants of Earth, we will deepen our shared understanding, envision the possibilities of space, and drive forward concrete space research and business creation through these activities.
