Danielson Crater - Mars Reconnaissance Orbiter
Layered sedimentary rocks on the floor of the 67 km wide Danielson Crater, located in Mars' Arabia Terra region. Semi-regular thickness variations suggest that sediment deposition was influenced by astronomical cycles, like changes in axial tilt, axial precession and orbital eccentricity. These rocks have been deeply eroded by wind, exposing the many thousands of layers that accumulated over eons.
This image 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 December 10, 2006. It uses CRISM observation HRL00003551 and CTX observation P02_001744_1879_XI_07N006W.
