Résumé en anglais

Few impact craters have been observed so far on Titan by the CASSINI orbiter. A 80 km diameter crater (called Sinlap) has been observed by all three imaging instruments (ISS, VIMS and Radar). Observations at infrared and radar wavelengths provide very complementary information on the composition, topography and surface roughness of the surface materials. We first investigate the spectral characteristics of the Sinlap area using VIMS data, in order to map the spectral heterogeneities, highlighting the different compositional and physical characteristics of the materials excavated by the impact. These units are then compared to the radar observations acquired at T3. The differences between optical and radar properties are discussed in terms of composition and vertical heterogeneity< Réduire
