AB - Obtaining in-situ lunar soil samples is fundamental to studying the  characteristics of lunar surface resources. A circular cutting sampling  method is proposed, and its sampling characteristics are explored by  theoretical analysis and numerical simulation. The results indicate that  the traditional vertical cutting sampling will cause serious damage to the  sequence structure and physical properties of samples. Circular inner blade  cutting sampling can avoid the disorder of particle sequence, but the design  of the inner blade will force the particles to move to the coring barrel,  causing sample disturbance. Compared with vertical and inner-blade cutting  method, circular outer blade cutting sampling reduces sample disturbance by  61% and 47.5%, respectively, making it the optimal sampling method. These  research findings can provide theoretical and technical support for  superficial sampling in deep space.
