Galle is an impact crater of 230 km of diameter located on the planet Mars by 50,9 ° S and 329.1 ° E In the quadrangle of Argyre, on the western border of Noachis Terra in contact with the Impact basin of Argyre Planitia. He owes his name to the German astronomer Johann Gottfried Galle (1812-1910).

The Galle crater is nicknamed Happy Face crater By the Anglo-Saxons because of the illusion of smiley given by interior reliefs formed by a mountainous circle arc (undoubtedly a fragment of central ring given the size of this crater) and two small mountain massifs at the bottom of this crater.
A second crater, smaller than Galle, having the same particular characteristics was discovered not far from there by Mars Recognition Orbit the in the Nereidum Montes region, by 45,1 ° S and 305 ° E , north of Argyre Planitia [ 2 ] .
