000003911 520__ $$aA good knowledge of Mercury’s crust is essential in fields as different as planetary formation, interior structure models, thermochemical evolution, volcanic history, surface mineralogy, or impact cratering. Although gravity anomalies and shape measured by the MESSENGER spacecraft can be converted into crustal thickness maps with unprecedented accuracy, these data do not directly constrain the average crustal thickness. Determining this crucial parameter requires additional assumptions about the mechanical equilibrium of the crust and mantle, often going under the name of isostasy. Previous studies of that kind predicted that Mercury’s crust is on the average rather thin, with a 2
