PSP_007704_1765_RED_abrowse~0.jpgProposed MSL Landing Site in Miyamoto Crater (MULTISPECTRUM; credits: Lunexit)56 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.MareKromium

Psp_009729_1735_red.jpgTerraced Fan in Aeolis Planum Region (possible True Colors; credits: Lunar Explorer Italia)57 visiteThis image shows the South-Western Region of a degraded crater’s floor, located near the Equator. The high-standing ridge near the left side of the scene is a terrace that slumped off the crater’s rim (located to the far left of this frame, but out of the image). The bumpy terrain near the bottom of the image is also material that has slumped off the crater rim.
The center of the image contains a terraced fan. The fan emanates from a valley (not pictured, located in the lower part of the scene) that intersects the crater’s south rim, which suggests that the valley might have transported fluid, likely water, into the crater. If this happened, then the fan marks where the flow deposited its sediment.

PSP_010281_1510_RED_abrowse-00.jpgSedimentary Layers in Columbus Crater (ctx frame - possible True Colors; credits: Lunar Explorer Italia)57 visiteThis image covers a portion of the North-Eastern Inner Wall of Columbus Crater, located in the Southern Hemisphere of Mars and is approx. 100 Km (about 60 miles) in diameter.
Layered sedimentary rocks are found on the Crater Walls and Floor, and may have been deposited by water or by wind. These rocks have subsequently been eroded to expose their successive layers in cross-section.
The near-infrared spectrometer CRISM has revealed that these layers contain various hydrated minerals.
