Chemical composition analysis of Titan's equatorial and midlatitude surface regions

Abstract

The Cassini cameras and especially the Visual and infrared Mapping Spectrometer has provided a sequ diversity of Titan's surface spectrum from flybys performed during the 13 years of Cassini's operation. surface chemical composition is of great importance for the understanding of the atmosphere-surface-inter Soi crater region with the well-preserved Soi crater in its center, spans from Titan's equatorial regions to provides a rich diversity of landscapes, one that is also representative of the diversity encountered across T at 1:800,000 scale using Cassini SAR and non-SAR data and produced a geomorphological map using th [1] and [2]. The VIMS coverage of the region allowed for detailed analysis of spectra of 262 differen transfer technique [3;4] and a mixing model [5;6], yielding compositional constraints on Titan's opti constraints on composition on the near-surface substrate were obtained from microwave emissivity. We id units, 3 of which were not previously described, and derived combinations of top surface materials betwe materials, water-ice, and methane. We found no evidence of CO and NH ice. We also observe empty which mark the most southern extent of Titan's north polar lakes. We use the stratigraphic relations bet the relation between the geomorphology and the composition of the surface layers to build hypotheses o the regional geology.
