Extended Data Fig. 5: Craters around the Tianwen-1 landing site.
From: Surface characteristics of the Zhurong Mars rover traverse at Utopia Planitia
a, The distribution of the mapped craters (diameters > 1 m) in the circular region surrounding the Tianwen-1 landing site, overlaid on the HiRISE image (ESP_069665_2055). C1, C2, C3 are three large craters (diameter > 200 m) in this area. The circular region is centred on 109.925° E, 25.048° N with a diameter of 4 km, and its centre is 1 km south of the Tianwen1 landing site. b, A log-log plot of the incremental sizefrequency distribution of craters. The diameter interval is √2D m and the crater diameter refers to the middle value of each bin. c, A degraded crater with smooth rims imaged by NaTeCam on sol 60 (13 July 2021). d, A crater almost fully filled with sand imaged by NaTeCam on sol 23 (6 June 2021).
