Experimental and Numerical Advances in Planetary Cratering Impacts

Abstract: Space exploration studies over the previous decades have shown that there are various impact craters on planetary surfaces. At present, it is generally believed that the formation of impact craters is an extremely important geological and impact dynamic process in the evolution of celestial bodies. The study and progress on impact crater formation on celestial bodies are reviewed in this paper, with an emphasis on the new insights and findings in the past decade. This paper strives to cover the frontier of research in a comprehensive manner and sorts out research threads to provide ideas for scholars. First, we briefly review the history and significance of the study of impact craters, and introduce the relevant progress of research methods, which include impact experiments and numerical simulations. Then, we summarize the emphases and limitations of recent research according to cratering stages. Finally, we discuss the current predicament and future trends of related research from numerical simulations and laboratory experiments. To advance the depth and scope of planetary cratering impacts study, some perspectives and recommendations for future investigations are provided.
