The origin of life represents a fundamental planetary phenomenon that demands the integration of multidisciplinary approaches to fully comprehend. This session explores how planetary processes create and sustain the geochemical conditions necessary for life's emergence and early evolution. We welcome studies investigating atmospheric and surface chemistry on early Earth and Mars; redox processes across the atmosphere, hydrosphere, and lithosphere; prebiotic molecular synthesis and complexity; mineral-catalyzed organic reactions; and the application of machine learning to biosignature detection. These approaches enhance our understanding of habitability on early Earth, Mars surface environments, and potentially other planetary bodies. This session welcomes theoretical, experimental, and observational studies that investigate the planetary processes driving life's emergence and early evolution.
