November 6, 2009--An ancient, 22-mile-wide (35-kilometer-wide) impact crater, most likely eroded by flowing water, was among several Martian features captured in new high-resolution pictures taken by the European Space Agency's Mars Express orbiter.

The probe recently aimed its high-resolution camera at a boundary region of Mars near what was once a tectonically active fracture zone. Scientists think this region experienced a process called subrosion--in which water erodes subsurface rocks and causes the overlying layers to collapse in a chaotic fashion.
