Venusian_Clouds_tracking_infrared_2_b_H.jpgVenusian cloud structures - Night view (1)58 visiteOriginal ESA caption:"Tracking cloud motion and starting to characterise the wind speed is an exercise that the Venus Express scientists have already started. A spectacular night view of the mid to low atmospheric layers over low latitudes (between 20º and 90 º South) by VIRTIS, show clouds being clearly pushed by winds.
"We can now make a first qualitative assessment of the wind fields and circulation, which is comfortably matching with previous measurement from the Galileo mission over the North Pole", said Giuseppe Piccioni.
"We are now collecting more data from different atmospheric depths, to be able to provide the first precise numbers, possibly in the near future".

Aeolian_Features-Dust_Devil-MGS-00.jpgRunning Winds... (Original NASA/MGS/MSSS b/w Frame)58 visiteCaption NASA originale:"This MGS-MOC image shows a bright plain West of Schiaparelli Crater, which is host to several features, some of them long-lived and others that are transient. The circular features scattered somewhat randomly throughout the scene are impact craters, all of which are in a variety of states of degradation.
Toward the right (Dx - South-West) corner of the image, there is a small hill surrounded by ripples of windblown sediment, and near the center (a little to the left) of the image, there is an active DD casting a shadow to the east as it makes its way across the plain".
Location near: 5,9° South; 348,2° West
Image width: ~3 Km (~1,9 mi)
Illumination from: upper left
Season: Southern Autumn

North_Polar_Features-Dunes-MGS-10.jpgDefrosting North Polar Dunes (Original NASA/MGS/MSSS b/w Frame)58 visiteCaption NASA originale:"This MGS-MOC image shows a portion of a sand dune field in the North Polar Region of Mars. The dunes are covered with frozen CO2, which accumulated over the Autumn and Winter months in the Northern Hemisphere. During the Spring, the time at which this image was acquired, the CO2 begins to sublime away, going directly from solid to gas, just as dry ice does here on Earth.
The dark spots, streaked by blowing winds, may be places where the frost has been removed (exposing underlying dark sand), places where the grain size or roughness of the frost has increased (increasing shadowing due to the change in texture), or both".
Location near: 79,7° North Lat. and 148,3° West Long.
Image width: ~3 Km (~1,9 mi)
Illumination from: lower left
Season: Northern Spring
