Session Link: https://agu.confex.com/agu/agu26/prelim.cgi/Session/280609 Description: We focus on the mechanics of planetary landscapes and their evolution over time through remote sensing observations, modeling, experimentation, and theory. Planetary landscapes are shaped by varied dynamic processes as the interface between the solid planet and fluid/gaseous envelopes or outer space. Thus, tracking the present and past transformations of planetary surfaces provides a window into their evolution over time. Over billions of years, rocky and icy bodies can evolve into or away from potentially habitable worlds. This has important implications for our understanding of broader habitability in the Solar System and beyond, as surface conditions are recorded in the landscape. We welcome contributions on topics across both endogenic and exogenic phenomena such as glacial, fluvial, aeolian, mass wasting, geothermal, volcanic, tectonic, and impact-related processes, and beyond. This session is listed in EPSP and co-organized and cross-listed with Planetary Sciences. We look forward to receiving your abstracts!

Plesko (LANL), Stephanie Bouchey (SNL), Jessie L. Dotson (NASA/ARC), Dawn M. Granninger (JHU/APL), and Sean P. Stokes (LLNL) 11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11 [AGU2026] SESSION P011: EXPECTATIONS AND LIMITATIONS IN THE SEARCH FOR LIFE - TOWARD A COHERENT FRAMEWORK FOR LIFE DETECTION The Louisiana State University-led AGU-2025 Townhall on expectations and limitations in the search for life formulated key community questions across geology, biology, engineering and policy. We seek to advance and consolidate these findings in the context of those proposed by the KISS Institute's Biology of Biosignature Detection Workshop, DARES Task Force 2, SFL-SAG, NAS-NASA Science Strategy for the Human Exploration of Mars, and COSPAR's Panel on Planetary Protection. Accordingly, we welcome analog field, laboratory, and computational findings that constrain key goals in life detection. Establishing least common denominators of life's limits across the Solar and exoplanetary systems, including energetic, abiotic, and geologic thresholds, is crucial to advancing new work motivated by Drake's Equation. Additionally, research characterizing interstellar objects traversing our Solar System is of great interest to reveal habitability constraints that are otherwise technologically inaccessible (even in the age of observatories like James Webb). All such works are welcome at: https://agu.confex.com/agu/agu26/prelim.cgi/Session/282993 12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12 [AGU 2026] SESSION P024: SMALL SOLAR SYSTEM BODIES - SAMPLE RETURNS, JWST, GROUND-BASED ASTRONOMY, AND MORE Recent (e.g., OSIRIS-REx, Hayabusa2), ongoing (e.g., New Horizons, Psyche, Lucy, Tianwen-2, OSIRIS-APEX, HERA), and upcoming (e.g., MMX, MBR Explorer to the Asteroid Belt, DESTINY+, RAMSES) and powerful telescopic facilities (e.g., JWST, adaptive optics, next-generation ground-based observatories) continue to expand our understanding of the diversity and complexity of small Solar System bodies. These objects preserve essential clues about the early Solar System, including accretional processes and thermal evolution. Sample return missions are providing ground truth to remote observations, helping decode planetary formation and evolution. National and private space programs are entering the arena and private companies are pushing forward with asteroid prospecting missions. Together, these efforts signal a new era in the study of small bodies-one that is increasingly collaborative, diverse in methods, and rich in discovery potential. We invite abstracts including, but not limited to, space mission data, ground-based observations, modeling, sample returns, planetary defense, and private-sector initiatives. Deadline: Wednesday, 5 August 2026 (23:59 EDT / 03:59 UTC) The conveners: Julie Castillo-Rogez, Bryan Holler, Franck Marchis 13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13 [AGU 2026] SESSION P034: TITAN - SCIENCE, EXPLORATION, AND FUTURE HORIZONS We invite abstract submissions to Fall AGU Session P034. Titan: Science, Exploration, and Future Horizons https://agu.confex.com/agu/agu26/prelim.cgi/Session/283507 Titan's thick atmosphere, methane hydrological cycle, and potential subsurface ocean make it a unique laboratory for planetary and prebiotic science. As preparation for the Dragonfly mission continues, integrating legacy Cassini-Huygens data with new observations and modeling remains essential. This session solicits presentations on all aspects of Titan science, including atmospheric dynamics, surface geomorphology, organic chemistry, and interior geophysics. We welcome all abstracts, including data-, modeling-, or laboratory-focused studies, analog fieldwork, and future instrument developments. Submissions from researchers at all career stages and across interdisciplinary boundaries are highly encouraged. Hope to see you at AGU this fall!

The goal of the workshop was to develop concepts of how these four areas would be able to work together to operate an actual landed Mars mission. Major recommendations include: All four areas should be included in planning from the very beginning, as trying to incorporate planning from one area after decisions in others have already been made is very ineffective. Interactions to include all areas in planning should not be a one-time occurrence, but should take place on a regular, interactive basis. The executive summary and the final report for that meeting are available on line at: https://exploremars.org/affording-mars/ 16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16 2026 SCHWEICKART PRIZE: WINNERS ANNOUNCED - DEFEND NEW FRONTIERS Brian Murphy and Richard Cannon, of the University of Edinburgh, were selected as the winners of the 2026 Schweickart Prize in Planetary Defense.
