Bond Crater - Mars Reconnaissance Orbiter
Rugged terrain on the southeastern rim of Bond Crater imaged by Mars Reconnaissance Orbiter. Erosion in the rim has incised into the underlying rocks, exposing knobs of erosionally-resistant material, which are likely crystalline rocks which underlie the surface at depth.The Bond crater impact occurred in some of the oldest terrain on the Martian surface, which shows extensive evidence of reworking by water. In the near infrared, the color of these rocks suggests that they contain clay minerals, which formed through the interaction of these rocks with water.
The surface here has been shaped by water in more recent history as well. The small channels here are likely runoff channels from the last Martian ice age. Although located in the southern mid-latitudes, this location was probably exposed to a glacial or tundra-like environment.
This false-color image uses a surface spectrum ranging from 380 nm to 2600 nm, which has been squeezed down to resemble what humans would see if all color variations occurred within the range of human vision (380-780 nm). 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 27, 2007. It uses CRISM observation HRL0000407E and CTX observation P03_002365_1469_XI_33S035W.
