Sera Crater Dunefield - Mars Reconnaissance Orbiter
Dunefields in Sera Crater, a 28 km diameter impact crater in Mars' Arabia Terra region. The crater is partially infilled by layered deposits, some of which appear to be rhythmic deposits. Rhythmic deposits have regular or semi-regular variations in layering thickness. These changes are usually interpreted as the result of long-term orbital and axial cycles, which in turn create regular climate cycles.
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 22, 2006. It uses CRISM observation FRT000037F7 and CTX observation P02_001902_1889_XI_08N001W
