Regolith Workshop 2010

REGOLITH ON SOLAR SYSTEM BODIES

December 1-3, 2010

Observatoire de Paris – CIAS (site Meudon)

AIM

The workshop is aimed to join together experts in study regolith properties of Solar system bodies by various observational techniques (photometry, polarimetry, spectroscopy, radiometry, radar), and experts in laboratory and numerical modeling. The main goal is to improve our understanding of surface regolith properties of inner and outer Solar system bodies.

MAIN TOPICS

Present knowledge of regolith properties of atmosphereless bodies as derived by various techniques
- photometry
- polarimetry
- spectroscopy
- radiometry
- radar data
- space missions data

Modeling of surface properties of atmosphereless bodies
- theoretical models
- numerical modeling
- laboratory modeling

Effects of space weathering

Constraints from meteorites

Comparison of surface properties of inner and distant Solar system bodies
