Hello Everyone
In the video "On Mars Curiosity Did a Great Job, Evidence of Fluid Flow through the Rocks Observed by NASA'S Rover" you can se a detailed Panorama Acquired by NASA's Mars rover Curiosity from Mars at "Mount Sharp" 'Vera Rubin Ridge',
Researchers used the Mast Camera (Mastcam) on NASA's Curiosity Mars rover to gain this detailed view of layers in "Vera Rubin Ridge" from just below the ridge.
The scene combines 70 images taken with the Mastcam's right-eye, telephoto-lens camera, on Aug. 13, 2017, during the 1,785th Martian day, or sol, of Curiosity's work on Mars.
The panoramas shows details of the sedimentary rocks that make up the "Vera Rubin Ridge." This distinct topographic feature located on the lower slopes of Mount Sharp (Aeolis Mons) is characterized by the presence of hematite, an iron-oxide mineral, which has been detected from orbit. The Mastcam images show that the rocks making up the lower part of the ridge are characterized by distinct horizontal stratification with individual rock layers of the order of several inches (tens of centimeters) thick. Scientists on the mission are using such images to determine the ancient environment these rocks were deposited in. The repeated beds indicate progressive accumulation of sediments that now make up the lower part of Mount Sharp, although from this distance it is not possible to know if they were formed by aqueous or wind-blown processes. Close-up images collected as the rover climbs the ridge will help answer this question. The stratified rocks are cross cut by veins filled with a white mineral, likely calcium sulfate, that provide evidence of later episodes of fluid flow through the rocks.
The panorama has been white-balanced so that the colors of the rock materials resemble how they would appear under daytime lighting conditions on Earth. It spans from southeast on the left to west on the right.
