PSP_005514_1360_RED_abrowse~0.jpgDunefield inside Rabe Crater (False Colors - elab. Lunexit)57 visiteThis image shows part of the floor of Rabe Crater, a large (about 108 Km, or approx. 67 miles in diameter) impact crater in the Southern Highlands.
Dark dunes — accumulations of wind blown sand — cover part of crater's floor and contrast with the surrounding bright-colored outcrops. The extreme close-up view reveals a thumbprint-like texture of smaller ridges and troughs covering the surfaces of the larger dunes.
These smaller ripples are also formed and shaped by blowing wind in the thin atmosphere of Mars.
One puzzling question is why the dunes are dark compared with the relative bright layered material contained within the Crater.
The probable answer is that the source of the dark sand is not local to this Crater; rather, this topographic depression has acted as a sand trap that has collected material being transported by winds blowing across the plains outside the Crater.

ESP_019612_2250_RED_abrowse.jpgMud-Volcanoes (?) in Acidalia Planitia (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)103 visiteThis proposed future Mars Landing Site in Acidalia Planitia targets densely occurring Mounds thought to be "Mud Volcanoes".
Mud Volcanoes are geological structures formed when a mixture of gas, liquid and fine-grained rock (or mud) is forced to the Surface from several meters to kilometers underground.
Scientists are targeting these Mud Volcanoes because the sediments, brought from depth, could contain organic materials that might provide evidence for possible past and present microbial life on Mars.MareKromium12/10/10 at 07:47walthari: certamente andreagg e questa infatti ? la caratter...
