Underestimation of Planetary Contraction Due To Obscuration by Surface Roughness: The Case of Mercury
Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling. Here we investigate the possibility that the tectonic r...
