The landing ellipse, measuring 100 x 15 km, is located close to the equator, in the southern highlands of Mars. The region was chosen based on its relatively flat and smooth characteristics, as indicated in the topography map, in order to satisfy landing safety requirements for Schiaparelli.
NASA’s Opportunity rover also landed within this ellipse near Endurance crater in Meridiani Planum, in 2004, and has been exploring the 22 km-wide Endeavour crater for the last five years. Endeavour lies just outside the south-eastern extent of Schiaparelli’s landing ellipse.
The region has also been well studied from orbit and is shown to host clay sediments and sulphates that were likely formed in the presence of water. Indeed, a number of water-carved channels are also clearly visible, in particular in the southern portion of the image.
