Martian Landing Area Morphology Interpretation and Quantitative Analysis of the Zhurong Rover

Tianwen-1 lander and rover successfully landed in the southern Utopia Planitia of Mars on May 15, 2021. As China's first Mars exploration mission, Tianwen-1 achieved orbiting, landing and patrolling tasks in one mission. The Zhurong rover had traveled 1064 meters till August 30, 2021. Utilizing the photogrammetry methods to produce mapping products from high-resolution orbiter remote sensing images, and to analyze the landing area environment，is not only important for the path planning and safe driving of the Mars rover, but also provides fundamental information for science research. This paper focuses on the Tianwen-1 landing area (within the surrounding 20 km of the landing point), and utilizes the 5 m/pixel CTX DOM and HiRISE, Tianwen-1 DEM product data to quantitatively analysis the impact crater density, impact crater depth, depth-to-diameter ratio, etc. Further interpretation and analysis of the geomorphic feature and geological background of the landing area are conducted. The crater statistics and geomorphic feature analysis are valuable to support geological evolution study of the Utopia Planitia.
