Chaotic Candor Chasma (Released 4 October 2004)

THEMIS has taken some great pictures of Valles Marineris, the largest canyon in the solar system. If this canyon were on Earth, it would stretch from New York to Los Angeles. Image of the Day toured some of the canyons that make up this vast system. This image shows an area in Candor Chasma. The Chasma walls and the chaotic canyon floor are visible on the top half of this image. The image's bottom half shows the slopes of the ridge formation in the middle of the Chasma. Wind etched surfaces and gullies are present there.
