Eroded Crater Fill in Tyrrhena Terra - Mars Reconnaissance Orbiter
Natural color image of layered fill deposits in an unnamed 26 km (16 mi) diameter crater in the highlands of Tyrrhena Terra (at 15 S, 89 E). This region of the highlands has been extensively resurfaced by water and volcanic activity. Many of the most ancient craters in this region have been completely or nearly completely filled in by these processes. Here, crater fill materials have been scoured by wind to form aerodynamically shaped ridges. Some of the exposed rocks are unusually rich in iron oxide minerals like hematite and goethite, which have given them a deep red-brown color.
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 November 21, 2006. It uses CRISM observation FRT0000315E and CTX observation P01_001503_1646_XI_15S270W
