3D Tomography and 2D SEM datasets of Lunar Agglutinate from the Apollo 11 Mission

The microstructural characterization of lunar agglutinate samples serves many essential purposes in Lunar science and cosmochemistry, from understanding the formation process of lunar regolith to preparing for human activity on the Moon. In this study, an advanced correlative characterization methodology was employed to examine the microstructure of a lunar agglutinate particle retrieved from the Apollo 11 mission. The multimodal characterization efforts were centered around 3D X-ray Computed Tomography (XCT) and were complemented by 2D techniques, including Scanning Electron Microscopy (SEM). The non-destructive nature of the XCT allowed us to preserve the lunar dust particles, while its 3D nature allowed us to extract meaningful microstructural information inaccessible via traditional 2D characterization techniques. The 3D microstructural characterization of four lunar agglutinate grains and 2D SEM images of one of the grains are presented here.
