Lunar Construction Site Mapping for Exploitation of Geotechnical Features

X-Hab 3D and Penn State propose an integrated Ground-Penetrating Radar/Multispectral Sensor (GPR/MSS) module that integrates a total station for precise localization. This innovation targets robotic lunar construction, where it is critical to identify hazards, map resource-rich areas, and autonomously prepare construction sites. By combining high-resolution subsurface scanning (GPR) with precise positioning and real-time control (total station and robotic arm), the system can detect rocks or voids, gauge regolith thickness, and locate potential water-ice deposits. Such real-time subsurface awareness bolsters safety, reduces mission risks, and aligns with NASA’s broader in-situ resource utilization (ISRU) strategies. Phase I funding will be allocated to integrating the GPR and total station within a single operational platform, constructing a controlled sandbox environment for testing, and developing software to acquire and analyze sensor data in real time. Experiments will show how GPR data can inform autonomous site preparation and regolith-based construction. This early-stage effort will validate key performance metrics including sensor accuracy, data reliability, and integration robustness, thereby paving the way for future scaling and refinement in Phase II. Beyond lunar applications, this GPR/MSS solution holds significant commercial and governmental potential on Earth, enabling geotechnical surveys, construction site evaluations, and non-destructive testing in diverse environments. Such versatility positions the technology as appealing to both space and traditional industries where rapid, high-fidelity subsurface data is paramount.
