Candor Chasma on Mars, in Color

October 12, 2009
This image from the camera system on NASA's Mars Odyssey was acquired of Candor Chasma within Valles Marineris. This visible color image shows the effects of erosion on a sequence of dramatically layered rocks. These layers were initially deposited within Candor Chasma and have subsequently been eroded by a variety of processes, including wind and down-slope motion due to gravity. Relatively dark materials appear to mantle some areas of the layered deposits; these dark materials are likely sand. Few impact craters of any size can be seen in this image, indicating that the erosion and transport of material is occurring at a relatively rapid rate, so that any craters that form are rapidly buried or eroded. This image was acquired using the thermal infrared imaging system's visible bands 1 (centered at 420 nanometers), 2 (centered at 550 nanometers), and 3 (centered at 650 nanometers), and covers an area approximately 19 kilometers (12 miles) in width by 50 kilometers (50 miles) in length.
