Permanent human settlements outside of low-earth orbit face technical and psycho-social challenges for the crew members and programmatic risks around funding and operating these missions, without clear public support and international involvement. A concept for the construction and operation of a lunar settlement named "Domi Inter Astra" (DIA), near the Shackleton Crater, was developed to understand the feasibility of a near-term permanent settlement crewed by international researchers and tourists. This project was created by a team under the Space Generation Advisory Council's auspices and a follow-on to our First Place design in the Moon Base Design Contest by The Moon Society. Technologies for

infrastructure, life-support, environment control, and robotics were selected using high-level trade studies to balance resource requirements, safety, reliability, operability, and maintainability of the base over a long (20+ year) operating life with 10-30 inhabitants. Technology roadmaps were developed for gaps in existing technologies, considering opportunities with ISRU and methods of closing the environment control and life support system loops. A wider range of human factors pertaining to the social environment onboard the base is discussed to ensure long-term stability. Architectural design choices were made, keeping these factors in mind while also considering technical and economic viability.

Large-scale space exploration projects must mitigate both public interest and funding risks throughout their life cycle. Economic roadmaps are introduced to diversify revenue streams throughout the settlement's design, deployment, and operation. Funding opportunities that evolve with the base design and functionality over time are identified for long-term economic sustainability. A polycentric model for international collaboration is explored to promote interest from current space-leading countries while providing opportunities for emerging space nations. The DIA lunar settlement case study showcases the interrelation between engineering, economics, architecture, science, social and management scopes. It highlights the interdisciplinary approach and inclusivity in the field of space sciences. This case study can help international and public-private partnerships to develop human space exploration capabilities further. The current DIA base plan could be used in many ways for educational

activities, for any level of students and professionals. Two types of activities could be design and analysis based and mini analogue missions. Students could devise and perform small experiments that relate to the base’s day-to-day activities as well as resources required, for example growing microgreens and plants in different conditions, geology surveys, 3D printing different objects and many such mini-projects. Graduate students and professionals could work on CAD modelling for structures, improving the architectural plan and the statistical analysis for the economical model.
