Investigating Mars: Hebes Chasma

This image shows the part of the southern cliff face of Hebes Chasma at the bottom of the image. The materials seen in the majority of this image are part of the erosion of the central mesa, perhaps created by a massive landslide. 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. It holds the record for longest working spacecraft at Mars. THEMIS, the IR/VIS camera system, has collected data for the entire mission and provides images covering all seasons and lighting conditions. Over the years many features of interest have received repeated imaging, building up a suite of images covering the entire feature. From the deepest chasma to the tallest volcano, individual dunes inside craters and dune fields that encircle the north pole, channels carved by water and lava, and a variety of other feature, THEMIS has imaged them all. For the next several months the image of the day will focus on the Tharsis volcanoes, the various chasmata of Valles Marineris, and the major dunes fields. We hope you enjoy these images!
