This project explores the innovative potential of constructing space habitat modules using a rhombic dodecahedral design. The focus is on uncovering the various benefits and applications of this geometric approach, particularly how it enhances the efficiency and functionality of habitats in space environments.
The reasoning behind the selected shape (rhombic dodecahedron) is outlined in the research paper published in the 2023 IAC conference proceedings titled "Morphology of Polyhedral Space Habitat Modules - Identifying the Ideal Form Using Multi-Criteria Analysis". This paper can be downloaded here.
A significant aspect of this research involves developing a novel unfolding deployment process, designed to allow modules to be transported compactly and deployed autonomously into their final form once in orbit. This process addresses previous limitations seen in traditional deployment methods by offering a simpler, more reliable solution. The unfolding mechanism, which will be detailed in a forthcoming paper accepted for the 2024 International Astronautical Congress, utilizes a series of mechanical rotations around the edges of flat-packed panels. This method not only ensures a collision-free assembly but also significantly reduces the complexity and cost associated with constructing large-scale space habitats. Additional funding for this project would enable the fabrication of the Nitinol torque springs required to demonstrate the lightweight unfolding mechanism.
Overall, the project represents a significant step forward in the field of space habitat construction, promising more efficient and feasible solutions for future space habitation systems. This research not only pushes the boundaries of current engineering and design practices but also opens up new possibilities for long-term human presence beyond Earth.
