Session Proposal: From Impacts to Habitability: Interdisciplinary Perspectives on Planetary Collisions and Prebiotic Chemistry (AGU25)

P015
From Impacts to Habitability: Interdisciplinary Perspectives on Planetary Collisions and Prebiotic Chemistry

Session ID#: 250759

Session Description:
Debris from planetary formation resulted in frequent bombardment to the planets, moons, and small bodies throughout the solar system. These impacts generate unique environments with extreme temperature and pressure gradients. Under these conditions, chemical inventories may have evolved along prebiotic pathways conducive to life’s emergence on Earth. Constraining the conditions during and after impacts is critical to understanding habitability on early Earth and other bodies. We invite contributions that explore  geologic, atmospheric, and prebiotic chemistry during and after the impact events on Earth and beyond, and the potential contributions to planetary habitability. We encourage a diverse approach leveraging modeling, experimental, and observational techniques.
