Eroded Crater Fill in Tyrrhena Terra - Mars Reconnaissance Orbiter
False color infrared 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.This image covers the infrared spectrum between between 800 nm and 2000 nm, where mineral colors that are difficult to distinguish in visible light become much easier to tell apart. This region of the spectrum shows that the surface has a more diverse composition than implied by the visible color image.
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
