The Lunar Sample Atlas provides pictures of the Apollo samples taken in the Lunar Sample Laboratory, full-color views of the samples in microscopic thin-sections, cutting views and diagrams that illustrate how the samples were subdivided for scientific analyses, and in situ views of the samples on the lunar surface. The atlas contains information about the type of sample (e.g., rock, soil), the lithology (e.g., basalt, norite), and a description of the sample.
