  2. Spectro-Polarimetric Imaging • The Lunar Regolith • Exposure to charged particles and micrometeor bombardment causes • accumulation of nanophase reduced iron (npFe0) on lunar regolith grains, • decrease in grain size, • enrichment with glass material and agglutinates. • Measurements of the grain-size distributions will aid in the evaluation of dusty lunar environments both for human sorties and potential sites for lunar facilities. • Composition and grain size distribution, and the effects of space weathering are also crucial for understanding the structure and evolution of the Moon. • The evolution of from immature to mature grains is manifested in their spectral and polarimetric properties. • But, none of the recent or planned lunar orbiter missions are equipped with polarimetric optics.
