3D shape and size data for 10084 and 14163 lunar regolith particles

This database contains 3D shape and size data for 10084 (Apollo 11) and 14163 (Apollo 14) real lunar regolith particles, along with STL files for the approximately 14,000 particles studied via X-ray micro-CT and X-ray nano-CT. The database also contains similar information for the lunar regolith simulant JSC-1A but for over 100,000 particles. There are also images for all 10084 and 14163 particles examined by SEM, which are different particles out of the same material. Each particle studied in 3D, ranging in size from 0.5 micrometers to 100 micrometers, has length, width, thickness, surface area, and volume measured. The directionally-averaged projected area is also computed. The dataset contains a 3D STL file for each particle that was studied by X-ray CT. There are files describing the data structure of each kind of data file.Note: The large image-stack files have been compressed using the Linux gzip app, which adds a ".gz" extension after the file's extension. Free apps such as 7zip are able to uncompress these files or the Linux app gunzip can be used. All data files (.dat, .txt, .mic) are in ASCII format when they are uncompressed.
