A Subtle Scarp South of the Tianwen-1 Landing Site
ESP_072579_2050  Science Theme: Tectonic Processes
This observation completes a stereo pair and is targeted to image a subtle scarp, visible in this anaglyph at the middle bottom of our cutout. What caused this topographic step? Is it the margin of a flow of wet sediments or lava? Or did the lower portion collapse, perhaps following the eruption of subsurface materials?

Also visible are pitted cones in the upper right of the cutout, perhaps from eruptions of wet sediments or lava. The Chinese Zhurong rover has been driving south in Utopia Planitia and may eventually reach the cones and scarp for closer inspection.
