Lunar Inflatable Habitats: A Comprehensive Literature Review

The development of inflatable lunar habitats represents a critical step toward sustainable human exploration of the Moon and beyond. Research efforts have primarily focused on optimizing these habitats for long-term durability, self-sufficiency, and adaptability in harsh extraterrestrial environments. Key studies highlight the advantages of inflatable structures, such as their lightweight, compact deployability, and efficient use of space. Inflatable habitats offer significant interior volume compared to rigid structures, allowing for better accommodation of life support systems and equipment. However, challenges related to structural integrity, radiation shielding, thermal management, and the integration of essential systems remain critical. Innovations such as hybrid approaches combining rigid elements with inflatable modules address some of these challenges by enhancing the robustness and longevity of the habitats. Researchers also explore advanced materials and in-situ resource utilization to reduce dependence on Earth-supplied materials, while design methodologies emphasize modularity and scalability to extend mission duration. Notably, these habitats must withstand lunar environmental factors such as micrometeoroid impacts, extreme temperature variations, and cosmic radiation, which require durable, multifunctional materials and careful engineering. Overall, the literature underscores the potential of inflatable lunar habitats as a feasible solution for sustaining human presence on the Moon. Interdisciplinary collaboration between space technology, architectural design, and engineering is critical in overcoming hurdles and advancing these habitats for future missions. The combination of inflatable structures with modularity, advanced life support systems, and ISRU technologies is poised to play a pivotal role in the next phase of human space exploration.
