Multiple Channels in Warrego Valles

After he Odyssey spacecraft had completed a full Mars year of observations of the red planet Image of the Day looked back over this first mars year. Focus was on four themes: 1) the poles - with the seasonal changes seen in the retreat and expansion of the caps; 2) craters - with a variety of morphologies relating to impact materials and later alteration, both infilling and exhumation; 3) channels - the clues to liquid surface flow; and 4) volcanic flow features. While some images have helped answer questions about the history of Mars, many have raised new questions that are still being investigated as Odyssey continues collecting data as it orbits Mars. The image shows an area in the Warrego Valles region. It was collected July 6, 2003 during northern summer season. The local time is 5pm. The image shows multiple channels dissecting the terrain. With this image, the 448th, the THEMIS Image of the Day completes its second (Earth) year. (The first image, of Nirgal Vallis, was released on 27 March 2002.) On behalf of the THEMIS team, we'd like to thank you for your continued interest and we hope you continue to come back through our third year and beyond.
