Dear Colleagues,
I hope you are doing well.
On behalf of the conveners, I would like to bring your attention to our AGU Fall Meeting session, “Dynamic Exospheres of Terrestrial Bodies through the Solar System,” which will be held December 7–11 in San Francisco, CA, USA.
We warmly invite you to submit an abstract to this session. We welcome contributions focused on remote and in-situ data analysis, modeling studies, instrumentation, and mission concepts related to neutral exospheres of terrestrial bodies throughout the Solar System, including Mercury, Venus, Earth, Mars, the Moon, Jovian moons, Titan, and exoplanets. For your convenience, a summary of the session description is included below.

P007: Dynamic Exospheres of Terrestrial Bodies through the Solar System
Session ID: 279690
The exosphere is the only atmospheric regime ubiquitous across all terrestrial bodies. Its composition, energetics, and density provide critical insights into photochemical pathways, long-term atmospheric evolution, and surface-constituent analysis through solar-driven interactions. The exosphere also mediates space weather coupling between neutral populations and local plasma environments, including solar and stellar winds, ionospheres, and plasmaspheres.
This session invites investigations of terrestrial exospheres throughout the Solar System and beyond, including exoplanets. We welcome contributions on physics-based and data-driven modeling, remote sensing using UV and visible observations, and novel inversion algorithms for retrieving density profiles. The session also encompasses experimental surface physics, such as sputtering and desorption, to inform source rates for surface-bound exospheres. In addition, we invite studies of neutral-plasma interactions, atmospheric escape, and the dependence of escape rates on orbital location and stellar activity. Presentations on current and upcoming missions dedicated to exospheric characterization are also encouraged.
