Our team presented one of our current projects at the 57th edition of the Lunar and Planetary Science Conference in Houston, Texas. In this work, we presented a numerical model to simulate water migration and stability in the Moon’s regolith, using heat and mass transport equations with simplified adsorption physics to improve computational efficiency. A sensitivity analysis showed that water distribution, particularly its depth and concentration, is strongly controlled by poorly constrained soil parameters, particularly the desorption energy, which dominates over diffusion-related factors. The results highlight that better constraints on sorption-related properties are crucial for accurately understanding lunar water behavior.
