Abstract The South Pole–Aitken (SPA) basin is the oldest and largest visible impact structure on Moon, making it a high priority science site for exploration missions. 492 km diameter Apollo peak-ring one of youngest basins within SPA basin. We selected three regions interest (ROIs) in which landing operational hazards are minimized evaluated their situ resource utilization (ISRU) potential. examined topography, slope, crater density, rock abundance, geologic mapping, mineralogy, inferred...
Abstract The lunar cratering record provides valuable information about the late accretion history of inner solar system. However, our understanding origin, rate, and timing impacting projectiles is far from complete. To learn more these projectiles, we can examine crater size‐frequency distributions (CSFDs) on Moon.

This work confirms that contain multiple past martian...
Abstract The crater record of a planetary surface unit is often analyzed by its cumulative size‐frequency distribution (CSFD). Measuring CSFDs involves traditional approaches, such as counting (TCC) and buffered (BCC), well geometric corrections, nonsparseness correction (NSC) (BNSC). NSC BNSC consider the effects obliteration on CSFD. On Moon, leads to two distinct states in which obtained do not match production CSFD—crater equilibrium nonsparseness. Crater occurs when each new impact...

With the renewed interest in lunar surface exploration, European Space Agency envisions to stimulate creation of communications and navigation services (LCNS) enable, among others, autonomous capabilities for rovers. As number satellites foreseen such a service is much smaller compared Earth-based global satellite systems, different complementary technologies are pursued improve attainable accuracy One way position provided by LCNS constrain their vertical using high resolution digital...

Abstract Mercury has one of the best‐preserved impact records in inner solar system due to absence an atmosphere and relatively unmodified ancient surface. However, our knowledge early record nature impacting projectiles are far from complete. To get a better understanding history, we examined large basins ( D ≥ 300 km) on Mercury. Here cataloged 94 basins, 80 which classify as certain or probable, 1.7 times more than previously recognized. We re‐evaluate crater densities using buffered...
Aeolian and fluvial processes on Earth show significant interactions. Within terrestrial desert environments, analysis of ~200 locations has revealed that where ephemeral or episodic rivers flow across a dune field the predominant alternate between aeolian fluvial, when dunes are active, they interact with one another. Avulsions can be major, channels in northern Kalahari having cumulative diversions 10s km. Considering Mars likely had an arid environment during period peak activity,...

Abstract Impact crater records on planetary surfaces are often analyzed for their spatial randomness. Generalized approaches such as the mean second closest neighbor distance (M2CND) and standard deviation of adjacent area (SDAA) available via a software tool but do not take influence curvature into account in current implementation. As result, measurements affected by map distortion effects can lead to wrong interpretations. This is particularly critical investigations global data sets...
