PS7.1 MediaOrigin of life and habitability: From Early Earth to the Solar System and Beyond
|Convener: Tilman Spohn | Co-Conveners: Véronique Dehant , Emmanuelle J. Javaux , C. Szopa , Lena Noack , Özgür Karatekin|
The aim of this session is to discuss the possible conditions and habitat for the origin and persistence of life in the solar system and beyond with emphasis on Earth, terrestrial planets, icy moons and exoplanets. We are interested in the conditions for habitability, the signatures of life, and the possible links between habitability and the evolution of planetary reservoirs (atmosphere, geosphere, hydrosphere, interior).
We invite contributions of relevance to the topic from all fields of Planetary Sciences and Biogeoscience including e.g., formation and structure of planetary bodies in the habitable zone, interior dynamics (convection, plate tectonics, and magnetic field), atmospheres, impacts and planetary evolution, geological evidence on Martian habitability, biogeochemical interactions, extremophiles and the limits of life, preservation and detection of biosignatures, mission concepts for exploration of planetary habitability.
