On Jupiter's largest moon Ganymede, we focus on the southern region of Nippur Sulcus, including the Epigeus palimpsest crater. This region displays geologically recent terrains and has good coverage of optical and near infrared remote sensing data, primarily returned by the NASA Galileo mission. We first use high‐resolution optical imagery to carry out a detailed geological mapping. We combine hyperspectral data to infer the surface composition of this area. We then apply two theoretical models. The first is a self‐similar clustering that uses the mapping of the grooves present in this region to infer the thickness of the ice shell. A second model is used to estimate the radar clutter noise induced by the estimated local topography, which is key for constraining future radar measurements. Based on all findings, we provide a possible evolutionary history of the Nippur Sulcus and Epigeus areas. This exercise shows the potential of an interdisciplinary data analysis combining wide‐ranging scientific objectives such as geology, surface composition, and geophysics in view of the future close exploration that will be conducted on Ganymede by the JUICE spacecraft. Our work combines multiple analysis techniques that could be applied to other regions of interest and will prove crucial when JUICE data become available. Plain Language Summary: On Jupiter's largest moon Ganymede, we focus on the region of Nippur Sulcus, including the Epigeus palimpsest crater covered by optical and near infrared remote sensing data acquired in the past by the NASA Galileo mission, to carry out a detailed geological and compositional analysis of this region. We then apply two theoretical models focusing on the estimation of the grooves' depth and on the radar clutter noise induced by the local topography to show how an in‐depth analysis combining geology, surface composition, and geophysics could achieve a broader understanding of a given region of interest. For high‐priority regions of interest to be studied by JUICE in detail, such a multidisciplinary analysis could ultimately reveal connections between the surface and fluid subsurface. Key Points: We focus on the Nippur Sulcus region on Ganymede to perform a detailed geological and compositional analysis of this regionNippur's grooves have a composition similar to that of small fresh craters and may penetrate 125–135 km into the icy crustTo reveal potential links between the surface and subsurface liquid pockets, clutter‐induced noise must be treated adequately in radar data [ABSTRACT FROM AUTHOR]

In this work, we analyze the ∼ 103 km-diameter Melkart impact crater on the surface of Ganymede, which is a ∼ 103 km impact crater located at the boundary between the two main geological units of the satellite, the light and dark terrains. Such crater is covered both by Galileo SSI and NIMS datasets allowing inference of any possible correlation between its geology and composition, as well as to investigate the evolution of the substrate units. We provide a geomorphological characterization of the crater by creating a high-resolution geological map, investigating the DTM and performing a strain analysis to infer its deformation. We find that the Melkart dome underwent strike-slip deformation with right-lateral kinematics. Moreover, this crater is a low strain end member with subtle deformation, which has been formed in an area of gradual transition between light and dark terrains. The results obtained through band depth and crystallinity maps of the study area do not reflect the evolutionary history of the crater, instead, they are representative of the different geological terrains affecting the subsurface of Melkart. Such result implies that the possible compositional differences between the crater's units might have been obliterated through time. Our analysis supports the interpretation that the material constituting the substrate of the crater might be heterogeneous suggesting that: (i) the transition between the two geological units might be gradual or ii) the dark material located over the study area only represents a thin layer draping the icy crust. • Analysis of a crater located at the boundary of Ganymede light and dark terrains. • High resolution geological map of Melkart impact crater on the surface of Ganymede. • Melkart is a low strain end member with subtle deformation from strain analysis. • The crater substrate material is heterogeneous from spectral analysis.
