Schiaparelli is a large impact basin about 460 km across, located in the eastern Terra Meridiani region of the planet’s equator. The image shows just a small part of the basin’s northwestern rim cutting diagonally across the image and a smaller 42 km diameter crater embedded in its rim. The image is centred on the equator of Mars, at about 14°E. It combines data from the nadir channel and one stereo channel of the High-Resolution Stereo Camera on ESA’s Mars Express to produce this 3D image. Stereoscopic glasses are required to see the 3D effect.
