Design and Experimental Study of a Drilling Tool for Mars Rock Sampling

“…The distribution of rocks on the surface of Mars exhibits high randomness. Through the examination of fundamental parameters such as Martian rock's hardness, shear resistance, and compression resistance [25][26][27][28][29][30], the target characteristic parameters of Martian rocks are summarized in Table 1. Core drilling string necessitates high hardness and efficient junk slots to address the complexities of drilling conditions effectively.…”
