Second Meeting

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)
