A significant, yet unanswered, question in the area of Near-Earth-Asteroid research is the effect solar wind has on the surface characteristics of these bodies. It would benefit the scientific community to better understand space weathering as it is important for all remote sensing studies of asteroid surfaces (Clark et al. 2002). We propose to replicate the electron component of our sun's solar wind on samples of ordinary chondrite meteorites using a Scanning Electron Microscope (SEM). Simulating the flux of charged particles (electrons) an asteroid at one astronomical unit (1 AU) would receive, we will use a range of time-scales and characterize any effects because rates of space weathering, at this time, are poorly understood. To characterize any changes in optical properties, and chemical or mineralogical structure, the meteorite samples will be tested spectrally and optically before and after the solar wind space weathering simulation.
