Meridiani Planum - Mars Reconnaissance Orbiter
A partially infilled depression in the Meridiani Planum region. The origin of this depression is unclear, but it may be an crater formed by a low-angle impact or a possible volcanic vent. Regardless of its origin, this depression was partially filled with sediments. Modern erosion of these sediments has exposed fine internal layering, creating the appearance of bathtub rings.
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 January 13, 2007. It uses CRISM observation FRT00003E24 and CTX observation P03_002179_1855_XI_05N001W.
