Young fresh lunar craters always present sharp and spectacular features. Today's Featured Image highlights the western slope of the Fabbroni crater located at the north edge of Mare Tranquillitatis, near the Apollo 17 landing site. Slope failures have created many narrow channels of granular material flowing down toward the center of the crater.
The reflectance of a material changes depending on various factors, such as the composition, grain size, and maturity. The crater cavity slope is composed of multiple layers and their debris. The mixtures of these materials exhibit various reflectances, which bring the flow features into sharp contrast.
Open up the full NAC frame and explore these spectacular meandering flows by yourself!
