Extended Data Fig. 9: Thermal simulations for the Zhurong and Phoenix landing sites.
From: Layered subsurface in Utopia Basin of Mars revealed by Zhurong rover radar
a, Temperature distribution based on the heat conduction simulation for the Zhurong landing site. b, The same as a, but for the Phoenix landing site. c, Temperature variation with depth, obtained from the results in a and b. d, Crossplots between temperature and depth/pressure for different solar longitudes (Ls). Phase curves of water (solid lines) and the eutectic points of possible brines (dashed vertical black lines) are presented. The pink dot denotes the triple point of water (273 K, 612 Pa). For the Zhurong radar data used in this paper, Ls 50 (Sol 11) and Ls 95 (Sol 113) represent the starting and the ending solar longitude (solar day), respectively.
