Fig. 1: Maps of Mars near the landing site in Mercator projection.
a, Mars Orbiter Laser Altimeter topography47. The rover landed in the southern Utopia Basin (marked) at 25.066° N, 109.926° E, northwest of the InSight landing site. b, The modelled total magnetic field strength at an altitude of 200 km (ref. 14). c, The corresponding geologic map48 whose key for the colours and geologic units is provided as Supplementary text. Note that resurfacing events in localized areas, such as around the Zhurong landing site, were not indicated in this standard geologic map. Major impact basin boundaries of Isidis (Is) and Utopia are shown with solid black (topography49,50) and dashed black (demagnetization21) lines.
