Abstract
Samples of soils collected by the Apollo 11 mission (10084) and the Apollo 14 mission (14163) were obtained from the NASA CAPTEM program. The particle size, shape, and internal porosity were characterized in three dimensions (3D) using a combination of X-ray computed tomography (XCT) and mathematical analysis, with various size and shape parameters measured and calculated for each particle. The purpose of this investigation was to obtain a database of 3D mathematical descriptions of the lunar soil so that light-scattering calculations could be made using this data on real lunar soil particles. This database is available through NIST. High-resolution SEM was also used to image the particles that were too small for the two XCT instruments used. Similar characterization was carried out on samples of JSC-1A lunar soil simulant, updating previous analysis, so that the 3D shape of real and simulated lunar soil can be quantitatively compared. Approximately 14,000 lunar regolith particles and 128,000 JSC1-A particles, each covering a wide range of size and shape, were characterized for this paper.Citation
