Schiaparelli in perspective

Schiaparelli is a large impact basin about 460 km across located in the eastern Terra Meridiani region of the planet’s equator. This image taken by the High-Resolution Stereo Camera on ESA’s Mars Express shows just a small part of the basin’s northwestern rim cutting diagonally across the image (bottom left–top right) and a smaller 42 km-diameter crater embedded in its rim. The interior of the crater is filled with sediments.
