Thursday, March 8, 2012 Martian dust devil 2,600-feet tall caught on camera A towering dust devil reaching half a mile in height has been pictured swirling across the surface of Mars by Nasa. The Agency’s Mars Reconnaissance Orbiter captured the image with its High Resolution Imaging Science Experiment (HiRISE) camera on February 16 this year as it passed over the Amazonis Planitia region of the planet. Despite the atmosphere on Mars being desperately thin – one per cent of Earth’s pressure – the planet's winds are strong enough to produce dramatic events and in the area observed, paths of many previous whirlwinds, or dust devils, are visible as streaks on the dusty surface.

14.03.2012., na Marsu je snimljen pješčani tornado visine 20 kilometara u području Amazonis Planitia koje se nalazi na sjevernoj hemisferi, ovu pojavu je ovjekovječila kamera HiRISE – High Resolution Imaging Science Experimenta koja se nalazi na marsovskoj letjelici Mars Reconnaissance Orbiter – MRO. Unatoč svojoj visini ovaj tornado je širine tek 70 metara.
