PSP_007779_2570_RED_abrowse~0.jpgDunes of the High Northern Latitudes (MULTISPECTRUM; credits: Lunexit)87 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_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.MareKromium
