This study examines the feasibility of sustaining planetary habitation alongside space tourism through advancements in technology, environmental systems, and in-situ resource utilization (ISRU). Utilizing resources such as lunar regolith and Martian soil can reduce Earth’s dependency for constructing habitats and producing essentials like oxygen and water. Technologies like closed-loop life-support systems, exemplified by ESA’s MELiSSA project, offer innovative solutions for long-term sustainability. However, challenges such as radiation exposure, energy reliability, and extreme temperatures present obstacles to accommodating tourists in extraterrestrial settings. Augmented reality (AR)-based tools provide intuitive solutions for resource management and task guidance, enhancing experiences for both astronauts and tourists. Integrating sustainable technologies, intuitive interfaces, and scalable solutions positions space tourism as a pivotal factor in advancing sustainable planetary life and opening new frontiers for human exploration and commercial ventures. As commercial space operations expand, emerging threats like cyberattacks, and orbital terrorism pose significant risks. This study proposes a hybrid economic and security framework, advocating for international regulatory oversight, AI-driven cybersecurity measures, and radiation-shielded habitat designs to ensure both financial sustainability and operational safety. These findings contribute to the growing discourse on space tourism viability, regulatory challenges, and technological innovations necessary for sustained human habitation in extraterrestrial environments.
