On the left, neutron imaging data from moon rocks collected during the NASA Apollo missions highlight variations in color based on how different parts of the sample, including different minerals, absorb neutrons. On the right, more details of the sample interior can be seen, including regions highlighted in magenta, which can help researchers determine where to make physical slices to extract only the elements of interest and preserves the rare moon rocks for further studies.
