The lunar cratering chronology uses crater size-frequency distributions (CSFDs) to derive absolute model ages (AMAs) for geological units across the Moon, and is adapted for use on the surfaces of various other Solar System bodies. New data collected by recent lunar missions, as well as additional and improved analyses of lunar samples, allow us to reevaluate and possibly improve the lunar chronology. We will remeasure CSFDs, i.e., N(1), and AMAs for the landing sites using high resolution images, and compare new results with previously determined values. Our ongoing project will complete the updated geological maps of the landing site for comparison with the sample collection locations, to investigate whether sample ages can be revised . We will then correlate them with our new CSFDs measurements of the area to potentially improve the accuracy of the lunar chronological curve.
