Extended Data Fig. 2: The geological background of Zhurong landing area.
From: Geomorphic contexts and science focus of the Zhurong landing site on Mars
a, Red rectangle centred at 24.7° N, 110.3° E (150 × 60 km2) represents the primary landing area and green rectangle centered at 26.5° N, 131.6° E (150 × 60 km2) represents the alternative landing area. Zhurong rover finally landed in the primary landing area. The landing area is in the southern Utopia Planitia (yellow rectangle, 20°N-45°N, 100°E-120°E), which is near the HLB (yellow line1) and the multiple suspected shorelines (lines in black19, red20, pink21, cyan22 and brown23). The base map is MOLA DEM37. b, Geological map1 (adapted from Tanaka et al. 2014) of the landing area and surrounding area. All regions are consistent with Supplementary Fig. 2a. The landing area is within the lHl unit. c, Zoning map of the landforms around the landing area3 (adapted from Ivanov et al. 2014). The coverage area corresponds to the yellow rectangle in Supplementary Fig. 2a and 2b. The base map is Viking Global Mosaic, which is available at https://astrogeology.usgs.gov/search/map/Mars/Viking/MDIM21/Mars_Viking_MDIM21_ClrMosaic_global_232m. d, North–south topographic profile across the landing area in southern UP (X-X’ gray dashed line in Supplementary Fig. 2c). The landing area is located in the transition zone between Area A and Area B, with an elevation range from -3900 to 4150 m.
