A tributary of the Grand Canyon of Mars, Hebes Chasma is pictured in this image taken by the European Space Agency's Mars Express orbiter on Oct. 10. Nearly 8 km deep, Hebes Chasma forms a giant trough of Valles Marineris, the largest canyon system in the solar system. Some 125 km across at its widest point, it's roughly 315 km long. Mars scientists believe that flowing water may have carved out the entire canyon system more than a billion years ago.

The above image, taken by the robotic Mars Express spacecraft currently orbiting Mars, shows great details of the chasm and the unusual horseshoe shaped indentation in the central mesa. Material from the mesa appears to have flowed onto the floor of the chasm, while a possible dark layer appears to have pooled like ink on a downslope landing.
