This paper describes the preparation of a lunar soil simulant with physical and mechanical properties similar to real lunar soil. The simulant was used to test an impact penetrator's performance, achieving a penetration depth of 545 mm after 894 shocks with 85% relative compaction. The study focuses on verifying the penetrator's diving capabilities and optimizing parameters for lunar soil exploration. The paper discusses impact penetrators for lunar soil exploration, focusing on their design, operation, and mechanical properties. It references various missions and instruments, including Apollo, Rosetta, MUPUS, KRET, MMUM, HP3, and IMS. No lunar regolith simulants or samples are explicitly mentioned or characterized in the provided text. The paper discusses the preparation of lunar soil simulant for testing an impact penetrator's performance. It outlines the design and operation of the penetrator, focusing on structural parameters and energy transfer efficiency. The simulant is used to simulate lunar soil properties for experimental verification. The paper discusses the preparation of a lunar soil simulant named GUG-1B, which mimics the mineral composition of Apollo-14 lunar soil. T
