The High Resolution Stereo Camera onboard ESA's Mars Express has obtained a multiple image coverage of Galle Crater, an impact crater located on the eastern rim of the Argyre Planitia impact basin at 51° southern latitude and 329° eastern longitude. Several images have been mosaicked to obtain a seamless image mosaic of the 230 km-diameter impact crater. Galle crater is informally known as "Happy Face" crater. Its interior shows a surface which is shaped by aeolian activity as seen in numerous dunes and dark dust devil tracks which removed the bright dusty surface coating.
