Crater on Mars

Part of the Schiaparelli Basin on Mars

This image shows a small part of Mars' huge Schiaparelli Basin (flat area on the left-hand side of the image) with a 42km-wide crater embedded in its rim (bottom right).

SCHIAPARELLI IS A LARGE IMPACT BASIN about 460 km across, located in the eastern Terra Meridiani region of Mars’ equatorial region.

The image here shows just a tiny part of the basin’s northwestern rim, cutting diagonally across the image from top left to bottom right (ie. the left-hand side of the image is part of Schiaparelli; everything else is outside the basin). The prominent crater at the bottom of the image is 42km wide and is embedded in Schiaparelli’s rim.

The image was taken on 15 July 2010 by the High-Resolution Stereo Camera (HRSC) on ESA’s Mars Express spacecraft. Ground resolution of the image is about 19 metres per pixel.

The image below shows a radar altimeter map of the entire Schiaparelli Basin, made by the Mars Orbital Laser Altimeter aboard NASA’s Mars Global Surveyor spacecraft. The large crater shown in the image above, is visible in this radar map on the rim of the basin at the 10 o’clock position (the orientation of the photo and map are turned 90 degrees to each other).
