ABSTRACT
Sand dunes have been found on Mars for the first time in Mariner 9 images of the Proctor Crater, within the southern highlands of Mars (McCauley 1972; Sagan 1972). Since then, other missions sent to Mars have provided us with thousands of images which reveal a rich diversity of dune forms on the poles and on many other craters, like the barchans found in the Arkhangelsky Crater (41.2◦S, 25.0◦W) by the Mars Global Surveyor (MGS) on 17.02.2004, which are shown in fig. 1. Understanding sand transport on Mars and quantifying trajectories of particles in saltation based on simulations can give us information about the atmosphere of that planet.
