The Analysis of Cones within the Tianwen-1 Landing Area

On 15 May 2021, the Zhurong rover of China’s first Mars mission, Tianwen-1 (TW-1), successfully landed in southern Utopia Planitia on Mars. Various landforms were present landing area, and this area recorded a complex geological history. Cones are one typical Planitia, they have great significance to local processes due diversity their origins. Using High-Resolution Imaging Camera (HiRIC) images collected by TW-1 orbiter, we identified total 272 well-preserved circular cones area. Detailed surveys spatial distribution, morphological characteristics, morphometric parameters conducted. A preliminary analysis surface characteristics these also provides additional information strengthen our understanding them. The results high-resolution topographic show that cone heights range 10.5–90.8 m basal diameters from 178.9–1206.6 m. We compared with terrestrial Martian analogous features found measured consistent ranges mud volcanoes small subset igneous origin cones. However, result is more favorable volcanoes, lower thermal inertia surrounding materials characteristic volcanoes. Based current evidence analysis, favor interpreting as
