Subsurface Thermal Modeling of Oxia Planum, Landing Site of ExoMars 2022

Table 1

Thermophysical parameters adopted in the first part of this work. Models A and B correspond to a thermal inertia of 160 TIU and 255 TIU, respectively. They are characterized by a composition similar to high-porous sedimentary rocks. Model C, instead, is characterized by a high thermal inertia (650 TIU), compatible with a composition clay dominant (e.g., vermiculite).
