PSP_007779_2570_RED_abrowse~0.jpgDunes of the High Northern Latitudes (MULTISPECTRUM; credits: Lunexit)86 visiteIn this image, we can see that the North Pole is surrounded by a vast “sea” of Basaltic Sand Dunes. In Northern Winter a Seasonal Polar Cap composed of CO2 ice (dry ice) forms and the surrounding dunes become covered with frost. In the Spring, the ice sublimates (evaporates directly from ice to gas) loosening and moving tiny dust particles.
The bright portions of the dunes in this image are areas still covered with seasonal frost while dark spots are areas where the frost is gone or dark dust has cascaded down the sides of the dune.
The dunes imaged here are similar to Barchan dunes that are commonly found in desert regions on Earth. Barchan dunes are generally crescent-shaped with a steep slip face bordered by horns oriented in the downwind direction. Barchan dunes form by winds blowing mainly in one direction and thus are good indicators of the dominant wind direction when the dunes formed.

PSP_007704_1765_RED_abrowse~0.jpgProposed MSL Landing Site in Miyamoto Crater (MULTISPECTRUM; credits: Lunexit)58 visiteMiyamoto Crater is located in South-Western Meridiani Planum (and South-West of the Mars Exploration Rover Opportunity Landing Site).
This image shows fairly smooth plains and some areas covered by Windstreaks.
The streaks suggest that wind is an active process here, depositing surface material downwind in this distinctive form. This Landing Site is adjacent to the Hematite-bearing plains unit where the Opportunity Rover sits.
The CRISM instrument has detected Phyllosilicates (Clay Minerals) at this Landing Site, which scientists believe to have formed in the presence of water.
The Mars Science Laboratory rover would investigate the mineral diversity here, which includes Phyllosilicates and Sulfate Minerals.MareKromiumDic 26, 2008

PSP_007678_2050_RED_abrowse~0.jpgProposed MSL Landing Site in Mawrth Vallis (MULTISPECTRUM; credits: Lunexit)57 visiteMawrth Vallis has a rich mineral diversity, including clay minerals that formed by the chemical alteration of rocks or loose “regolith” (soil) by water.
The CRISM instrument on the MRO Spacecraft has detected a variety of clay minerals here that could signify different processes of formation. The high resolution of the HiRISE camera helps us to see and trace out layers, polygonal fractures and, with CRISM, examine the distribution of various minerals across the surface.
This surface is scientifically compelling for the Mars Science Laboratory (MSL) Rover, although some of the terrain might be somewhat rough. Scientists use HiRISE images to find the safest possible Landing Site for the Rover.
This is one of four candidate landing sites in the Mawrth Vallis region.MareKromiumDic 26, 2008
