Supplementary material to: Highly resolved topography and illumination at Mercury south pole from MESSENGER MDIS-NAC

We produced a new higher-resolution topographic map of Mercury’s south polar region (75°-90° South, covering ~1.3 million km2) by using data collected by the NASA MESSENGER spacecraft’s Mercury Dual Imaging System (MDIS; Hawkins et al, 2007) over the years 2011-2015. This new map enables, e.g., the first detailed modeling of illumination and thermal conditions in these southern radar-bright locations and the first constraints on the nature and history of volatiles residing there, but it is also intended as a resource for other geophysical analyses and for the preparation of the BepiColombo mission, currently en-route to the planet.
