  1. Space Weathering Agent: Solar Wind • Bombardment of helium ions on olivine under vacuum conditions in the lab simulates space weathering of asteroids and other airless bodies. • The observed effects are: • reddening of the spectral slope • slight darkening of the olivine • attenuation of the 1 μm absorption band • formation of metallic iron in the outer layer of the mineral surface in powder and flat slab

  2. Space Weathering Agent: Solar Wind • Interpret reflectance spectra of the surfaces of airless planetary bodies • Compare spectra of meteorites to spectra of asteroids, to determine meteorite parent bodies The more we understand the processes and timescales of space weathering, the better we can:
