Craters-Proctor_Crater-PIA17421-PCF-LXTT-IPF.jpgProctor Crater's Dunefield (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/IPF)59 visiteIn this VIS image, taken by the NASA - Mars Odyssey Orbiter on July 4th, 2013, and during its 51.257th orbit around the Red Planet, we can see part of the very large Dunefield that is located located on the Floor of Proctor Crater (a large Impact Crater found in the Noachis Quadrangle of Mars, at about 48° South Latitude and 330,5° West Longitude).
Proctor Crater is approx. 168 Km (such as about 104,3 miles) in diameter and it was so named after Dr Richard A. Proctor, a British Astronomer (who was born in Chelsea - London, UK, on March, 23rd, 1837 and died in New York - USA - on September, 12th, 1888). Proctor Crater contains an approx. 35 x 65 Km (such as about 21,7 x 40,36 miles) Dark Dunefield that was one of the first Sand Dunefields ever recognized on Mars - note: this discovery was based on the NASA - Mariner 9 Spacecraft's images. Just out of curiosity, Proctor's Dunes are still being monitored by several Spacecrafts now orbiting the Red Planet (including the NASA- Mars Reconnaissance Orbiter) with the aim of identifying the changes (if any) which might have occurred - over time - in the shape of the Dunefield itself.

Craters-Unnamed_Crater-NT-PIA17420-PCF-LXTT-IPF.jpgUnnamed Crater with Dunefield (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)55 visiteIn this VIS image, taken by the NASA - Mars Odyssey Orbiter on July 2nd, 2013, and during its 51.232nd orbit around the Red Planet, we can see a relatively large, dark and, probably, "Migrating" Dunefield that is found on the Floor of an old and Unnamed Impact Crater located in the Martian Southern Region known as Noachis Terra.
Even this Dunefield (just like the one found on the Floor of Proctor Crater - please, refer to yesterday's APOD if you want to know more -, as well as many others, located on both Martian Hemispheres) is being monitored by several Spacecrafts now orbiting the Red Planet (including the NASA- Mars Reconnaissance Orbiter) with the aim of identifying the movements (---> shifting, if any) of the Dunefield and the changes (again, if any) which might have occurred - over time - in the shape of the Dunefield itself.

Many craters this close to the North Pole contain similar Dunefields".

Craters-Unnamed_Crater-Terra_Cimmeria-PIA16266-PCF-LXTT-IPF.jpgUnnamed Crater with Gullies and Dunefield in Terra Cimmeria (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)64 visiteIn this frame, taken by the NASA - Mars Odyssey Orbiter during its 49.393rd orbit around the Red Planet, several Gullies of different shapes, depths and sizes located on the Southern Rim of an Unnamed Impact Crater in Terra Cimmeria can be seen. As you may easily notice, there are way more Gullies on the North-facing Inner Rim (such as the Southern Inner Rim) of this Unnamed Crater, and the reason of such a remarkable difference is found, most likely, in the circumstance that the Southern Region of the Crater itself gets more Sun-related warming than the other one, which is corresponding to the South-facing Inner Rim (such as the Northern Inner Rim).
Also well visible towards the top of the picture, right at the base of the Northern Inner Slopes (Wall) of this Unnamed Cimmerian Impact Crater, there is a small and Dark Dunefield (probably formed - once you take into duly consideration the peculiar-looking shapes and surroundings of the Dunes forming it - by "Migrating Dunes". Dunes which may contain, among Dust, Rocky Sands and Volcanic Ashes, also a significant amount of Iron Oxide). It must be said, however, that a Surface Feature like this last one (---> the Dark Dunefield), is really very common, specifically at these Middle (Southern) Latitudes.
