Description

English: A dust devil on Mars, photographed by Mars Global Surveyor. The long dark streak is formed by a moving swirling column of Martian atmosphere. The dust devil itself (the black spot) is climbing the crater wall. The streaks on the right are sand dunes on the crater floor.

Magyar: Marsi porördög. A Mars Global Surveyor fényképén a hosszú sötét csíkot forgószél hozta létre. Maga a porördög (a fekete folt) éppen egy kráter falán kúszik fel. A kráter alján homokdűnék is láthatóak
