The identification and mapping of extraterrestrial resources are fundamental for efficient in-situ resource utilization, an activity that drives the sustainability of space exploration. Scouting micro-rovers, responsible for providing useful information to the main rover, can be utilized to support optimal decisions for investigation sites. Non integration of single, complex payloads enhances the modularity and mission-flexibility characteristics of these systems. This study presents the feasibility analysis of different conceptual designs of autonomous scouting micro-rovers with multi-instrument integration. These systems can be used for high-resolution resource scouting and mapping on the Moon and Mars. Different configurations of instruments are examined and compared in the system’s level impact, through design trade-offs methods. A variety of scientific sensors and tools are included to the study like spectrometers, ground-penetrating radar, cameras, laser spectroscopy systems, and drills, to enable comprehensive and efficient resource identification and geospatial mapping. The focus is twofold: i) assessing the system’s impact of integrating different configurations of these instruments within a compact, rugged, and energy-efficient small platform similar to a micro rover. Among others, examined criteria can be electro-mechanical design efficiency, effective communication and operational effectiveness, and ii) proposing and integrating algorithms that optimize the rover's autonomy and resources identification capabilities, and potential autonomous grid search strategies. This research highlights the challenges of accommodating diverse scientific instruments within a single micro platform, respecting, among others, the power, mechanical, data handling and operational requirements. This analysis proposes a framework for assisting the design of future missions, aiming for optimizing the in-situ resources mapping and leading the integration of emerging technologies in extraterrestrial bodies exploration.
