3d models and crack networks in support of the manuscript entitled Low thermal inertia of carbonaceous asteroid Bennu driven by cracks observed in returned samples

This archive contains some useful derived data products described in the manuscript "Low thermal inertia of carbonaceous asteroid Bennu driven by cracks observed in returned samples."3D models derived from X-ray computed tomography (XCT) and Structured Light Scanning (SLS) are provided for the two stones that were split by JSC curation, mottled stone OREX-800088-0 and angular stone OREX-800055-0. The 3D models (stl format) are aligned so that if they are opened together, they should assemble to produce the parent stone.Similarly, the "puzzle piece" stones with existing 3D models are provided so that if opened together they form an assembly. Two assemblies are provided. The first consists of two angular stones (OREX-800017-0 and OREX-800020-0) and the second consists of three mottled stones (OREX-800014-0, OREX-800023-0, and OREX-800073-0). Finally, the crack and pore networks segmented from XCT data that were used in the manuscript for thermal modeling are provided as tiff stacks (8-bit grayscale, where solid material has a pixel value of 0 and void space has a pixel value of 255). These can be imported directly into the NASA PuMA thermal modeling software. An accompanying Excel spreadsheet (info.xlsx) provides the pixel bounds that should be used to crop each dataset in PuMA before computing thermal conductivity. A screenshot is provided of the PuMA thermal conductivity module with the example values filled in.The uncompressed volume of this archive is approximately 15 Gb.
