How do habitability factors impact the economic feasibility of a sustainable human colony on Mars?

This research explores the complex relationship between survival requirements and economic feasibility in establishing a sustainable human colony on Mars. While much of existing discourse emphasizes transportation costs and rocket technology, this study repositions habitability factors—such as radiation protection, life-support systems, food and water production, and local resource utilization—as central to determining the true economic viability of colonization. Drawing from NASA reports, peer-reviewed literature, and cost modeling from government and private programs, the author presents a comparative framework that contrasts Earth-dependent construction with Mars-based approaches using in-situ resources.

The study identifies seven critical domains influencing mission costs: atmospheric pressure control, temperature regulation, radiation protection, dust mitigation, food and water systems, energy generation, and in-situ resource utilization. Through qualitative analysis, it reveals that Mars-based manufacturing—though requiring heavy initial investment in infrastructure and technology—offers long-term sustainability and cost reduction by minimizing launch mass and dependence on Earth’s supply chains. By quantifying these interdependencies, the paper demonstrates that survival infrastructure is not merely a technical necessity but a defining factor of economic strategy.

Ultimately, the research concludes that the feasibility of Mars colonization hinges on how efficiently humanity can integrate resource self-sufficiency into habitat design. It argues that sustainable colonization will depend on adaptive systems capable of closing environmental loops—recycling air, water, and waste—while leveraging local materials to reduce long-term costs. By bridging technological innovation with economic reasoning, the paper contributes a holistic framework for evaluating extraterrestrial settlement, offering insights relevant not only to space exploration but also to sustainable design and resource management on Earth.
