Investigating Mars: Hebes Chasma

This image shows the side of the large mesa at the top of the image and the southern canyon cliff face at the bottom. Materials on the floor of the chasma originated from both features. Although the cliff faces are eroding differently, both contribute to the rough floor seen in the center of the image. Hebes Chasma is an enclosed basin not connected to Valles Marineris. The Odyssey spacecraft has spent over 15 years in orbit around Mars, circling the planet more than 69000 times.
