Pasteur (Mars)

Named after Louis Pasteur - French chemist (1822-1895).

Dark sand dunes are clustered in the southwest of the crater. The orientation of the barchan dunes suggest that they were generated by northeasterly winds. The source of the dune's sand appears to be local. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On Mars large craters are named after deceased scientists, writers and others who have contributed to the lore of Mars. Small creaters (less than 60km) are named after small towns and villages.
