Abstract
An understanding of the mineralogical composition of Mercury’s surface is needed to shed light on the formation and evolution of the planet and a detailed study of the surface geomorphology will allow discriminating the relative extent and importance of exogenic and endogenic processes, surface modification (crustal differentiation and resurfacing), cratering, tectonics and volcanism. An improved knowledge of Mercury surface properties also represents a crucial achievement to understand the formation and evolution of the terrestrial planets. In order to analyze the geological and mineralogical characteristics of the Mercury surface, the integrated package SIMBIO-SYS (Spectrometers and Imagers for MPO BepiColombo - Integrated Observatory SYStem) is included in the scientific payload of the ESA mission BepiColombo, to be launched in 2014. The SIMBIO-SYS suite includes imaging channels, with high spatial resolution and stereo capability, and a spectrometer in the visible-near infrared range. The High Resolution Imaging Channel (HRIC) main objective is the characterization of special surface targets with high resolution (up to 5 m/px at periherm), which will be used in the context of the medium resolution Stereo Camera (STC) images for a comprehensive geological mapping of the Mercury’s surface. The multicolour HRIC images (broad-band filters centred at 550, 700 and 880 nm) will be useful to cross-correlate the surface composition with the morphological features, both at local and global scales. Here we present the expected performances of the HRIC in terms of surface mapping (mosaicing reconstruction, expected SNR, surface coverage. . . ), obtained by
