Investigations of lunar crater rays have revealed key insights not only into the formation and preservation of rays themselves, but also the role that rays play in distributing and mixing primary ejecta with local material [e.g., 1-6]. As such, an understanding of lunar rays is essential to understanding the evolution of the surface not only of the Moon, but other airless bodies. Sabuwala et al.  determined a relationship between the topography of pre-impact surfaces in granular cratering experiments and the number of rays of the resulting craters . In this work, we investigate the extent to which this trend is measurable in actual lunar impact craters.
