Quantifying the 3-Dimensional Shape of Lunar Regolith Particles Using X-Ray Computed Tomography and Scanning Electron Microscopy at sub-lambda Resolution

We now know that, in addition to the size distribution, the specific shapes and orientations of regolith particles play a major role in determining the light scattering properties of lunar soil and other planetary regoliths. Our goal is to model light scattering by using the shape and size distribution of actual lunar soil particles that are on loan to us for this study through NASA's Curation and Analysis Planning Team for Extraterrestrial Materials. By determining what aspects of the actual irregular particle shapes present in lunar regoliths influence what components of the scattering matrix for a volume of randomly oriented particles, we seek to advance our ability to quantitatively interpret spacecraft images, photometry, polarimetry, and spectral data.
