ISSI MUSEC Agenda 11/05/2026 – 15/05/2026
Topics :
1 – Surface Properties and their Variability – Effect on the Exosphere
- Global geological features and link to exosphere
- Local volatile concentration/coverage
- Multi-scale sputtering approaches (aging of surfaces)
- Temporal variability of the exosphere structure
- Key unknowns in exospheres models
2 – Observations and Experiments synergy with Numerical Models
- SBEs (adsorbed, amorphous) & coverage
- Reflection and energy accommodation of low energy atoms
- Direct comparison between lab experiments and numerical models (sputtering, micrometeoroids)
- Constraining the surface/exosphere using the current observations – Prediction for future observations
- Magnetosphere observations to constrain the surface-exosphere-magnetosphere interactions
- Icy surfaces – Effect on the exosphere, response to ions sputtering and radiolysis
3 – Linking the Different Scales and the Different Bodies
- Regolith structure / Porosity effects on the surface temperature, diffusion, sputtering, …
- Intragrain diffusion, implantation role on the surface composition
- Comparison between Mercury/Moon, or Icy bodies
- Applicability of the techniques developed to other airless bodies (or other fields)
