Abstract

This manuscript details specific operational aspects for DEIMOS (Developing & Evaluating In-Situ Martian Operations), a future analog astronaut mission facilitated by Habitat Marte, focusing on the critical role of in-situ resource utilization (ISRU) for Martian sustainability. We lay the groundwork for utilizing Martian regolith to 3D print essential tools and components, outlining the associated procedures from material ac quisition to fabrication. Our methodology, constrained by current technology, involves using a standard 3D printer to create tools for simulated Extravehicular Activity (EVA) soil collection, enabling evaluation of tool and glove efficacy for future design improvements. It's important to note that the soil collected during these EVAs will not be used in our 3D printing experiments, as its composition does not sufficiently resemble Mar tian regolith. Instead, upon returning to the simulated habitat, we will combine a Martian regolith simulant (MGS) with two distinct binding agents/polymers, followed by microwave heating to produce and analyze microwave-fired ceramic/pottery. Anticipated findings include the demonstration of the potential for robust regolith structures through sintering and the identification of a more durable binding agent. The overall sig nificance of this research is to advance human preparedness for long-term, self-sufficient habitation on Mars by validating fundamental ISRU processes and material properties in an analog environment.
