ESP_012065_9000_COLOR.JPGDeimos (Natural - but enhanced - Colors; credits: NASA/JPL/Univ. of Arizona)81 visiteHiRISE captured this enhanced-color image of Deimos, the smaller of the two moons of Mars, on 21 February 2009.
Deimos has a smooth surface due to a blanket of fragmental rock or regolith, except for the most recent impact craters. It is a dark, reddish object, very similar to Phobos.
There are subtle color variations — redder in the smoothest areas and less red near fresh impact craters and over ridges or topographic highs (relative to its center of gravity).
These color variations are probably caused by the exposure of surface materials to the space environment, which leads to darkening and reddening. Brighter and less-red surface materials have seen less exposure to space due to recent impacts or downslope movement of regolith.
With an image scale of about 20 mt/pixel, features 60 mt or larger can be discerned.MareKromium

PSP_003538_1885_RED_browse.jpgAres Vallis' Cataract (Natural Colors; credits: Lunar Explorer Italia)60 visiteThis image shows a dry cataract within Ares Vallis. A cataract is a large waterfall where there is a high, steep drop. The presence of this large cataract in Ares Vallis confirms that this channel was carved by water, probably in one or many large catastrophic flooding events.
This feature has many of the same characteristics as the cataracts on Earth associated with the flood that carved the Channelled Scablands in Washington State, including horseshoe-shaped headcuts and longitudinal grooves. These grooves in the lower portion of the image lead up to the cataract, with the water flowing from the south to the north in this image. It then flowed down the cataract into the smaller incised channel.
The horseshoe-shaped headcut here is only part of a larger cataract system, and probably formed during the last stage of flooding. The inner channels are now filled with dunes formed by wind blowing along the channel floor.MareKromium

ESP_011287_2165_RED_abrowse.jpgFresh Impact Crater in Utopia Planitia (Natural Colors; credits: Lunar Explorer Italia)60 visiteThis fresh Unnamed Crater is located in the Northern Mid-Latitudes. It is designated as fresh because of its very sharp rim.
The Crater has experienced some modification since it formed, including a few tiny craters on the South Wall.
The rough texture of the floor is suggestive of ground ice, which is expected to exist in the Mid-Latitudes. Ground ice aids gravity in moving material from the Crater Walls towards the center. Material is visible slumping off the North-Western Crater Wall in this fashion. The wavy texture of the center of the Crater floor suggests that material has been transported from the walls and merged in the center.
