Presently Mars is experiencing late spring in its northern hemisphere, and dust devil activity is picking up as summer approaches. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image of a cratered plain in southern Acidalia Planitia was acquired earlier this week on 5 September 2004. The arrow points to a dust devil observed that day. The image is located near 29.2°N, 30.3°W, and covers an area approximately 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.
