Distribuzione dei depositi eolici a ovest del cratere Endeavour (Meridiani Planium, Marte)

With a specific focus on the Opportunity rover, which is going through Meridiani Planum - located in Mars equatorial region – a morphological investigation through the use of HiRISE: high-resolution images was carried out. Researches have been performed to understand at what point the study of these environments and their classification was. There are different forms, for example ripples, TARs, polygonal dunes, transverse dunes, impact craters, ejecta and substrate. From this division a morphological map of the area was created. More accurate observations showed a particular distribution of polygonal dunes into the craters. For this reason a statistical analysis to determine a possible relationship between the diameters of the craters and the presence of the dunes was carried out. Then a further relationship was investigated between the height of the crater, its diameter and the ability (or not) of wind to transport the sand outside the crater, forming dune fields that go up on the side of the crater itself.
