1.Introduction In recent years, there have been significant advancements in the scope and depth of space exploration. Challenging missions, such as returning to the Moon and exploring Mars, are gradually being implemented. In deep space exploration, understanding the mechanical behavior of planetary geomaterials is crucial for various missions, including mission planning, landing system design,drilling and coring, base construction, in-situ resource utilization(ISRU), and asteroid mining. Researchers from diverse backgrounds have been actively advancing knowledge and driving innovation in this field. Fifteen years ago, the mechanical properties of soil and rock samples brought back from the Moon by the Apollo missions were investigated experimentally [1]. The testing of meteorietes,which can be obtained on Earth, also helps us to understand the Moon and asteroids. Recently, Prof. Saydam at the University of New South Wales established the commission of ‘Planetary Rock Mechanics' within the International Society for Rock Mechanics and Rock Engineering.
