Wednesday, February 8, 2012 Nasa spacecraft captures huge avalanche near Mars's north pole A Nasa spacecraft has captured an avalanche of fine ice and dust thundering over a cliff near Mars's north pole. It's not the first avalanche captured by the HiRISE camera aboard the Mars Reconnaissance Orbiter - Nasa first detected the phenomenon in 2008, believed to be caused by a thin 'crust' of frozen carbon dioxide (dry ice) which forms during the Martian winter. The HiRISE high resolution camera took the amazing photograph at 85 degrees north on the planet. The HiRISE camera is one of several hi-tech instruments on board Mars Reconnaissance Orbiter. It's the largest camera ever carried into deep space. Nasa's ground team says that the events are detectable by a cloud of fine material that erupts when avalanches collapse down slopes on the planet.

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.
