英文摘要	Chang'E-4, with the Yutu-2 rover, is the first lunar probe to successfully land and conduct a tour on the far side of the Moon from early 2019. We analyze the physical and mechanical characteristics of lunar soil through the in situ terrain data collected by the panoramic camera onboard the Yutu-2 rover. With the slip ratio and wheel sinkage obtained by the derived Digital Orthophoto Map (DOM) and Digital Elevation Model (DEM), the mechanical parameters of lunar soil are derived from the slip-sinkage model. These mechanical parameters and wheel size of the rover are used to obtain the pressure-sinkage curves, which can estimate the lunar soil strength. The experimental results indicate that the soil strength at the Chang'E-4 landing site is much higher than that at the Chang'E-3 landing site. The discrepancies in lunar soil strength between the two landing sites may be related to the local surface topography and degree of space weathering. ©2020. American Geophysical Union.
