| Description |
Natural color image of rhythmic layered deposits in Becquerel Crater, a 167 km wide impact crater in Arabia Terra. These deposits are located in a mound in the southern half of the crater. The mound layers show regular variations in thickness, forming alternating groups of thinly-spaced and widely-spaced layers which were likely deposited by wind. This type of bedding is commonly observed in regions where sedimentary deposits are controlled by astronomical cycles, such as changing axial tilt, precession, and orbital eccentricity, These cycles influence the regional climate, changing the rate at which sediments pile up. This natural color was created using the CRISM imaging spectrometer. Each pixel of a CRISM image contains a 500 point spectrum, from which a color can be reconstructed. This reconstructed color was overlaid on a higher-resolution image taken with the Mars Reconnaissance Orbiter Context Camera (CTX), which simultaneously took a photo while CRISM was collecting data. This image was taken on November 24, 2006. It uses CRISM observation FRT00003245, and CTX P01_001546_2016_XI_21N008W. Image Credit: NASA / JPL / JHUAPL / MSSS / Justin Cowart |
