About
Xue Long is a leading figure in lunar exploration and planetary geomechanics, whose work has directly shaped the success of China’s Chang’e missions. His research focuses on the mechanical behavior of lunar regolith, in-situ resource utilization, and the design of sampling strategies for extraterrestrial surfaces. Long’s most notable contribution is his pioneering study on surface sampling depth prediction for the far side of the Moon, published in 2025. This work, which has already garnered early citations, provided the critical mechanical parameters of lunar soil at the Chang’e 6 landing site—the edge of Apollo Crater—enabling precise, real-time adjustments during the mission’s groundbreaking far-side sampling operation in June 2024. By integrating contact indentation data from the lander’s instruments, Long established a robust framework for predicting sampling efficiency and subsurface conditions, a methodology now considered essential for future robotic and crewed missions. His achievements place him at the forefront of planetary surface engineering, bridging fundamental soil mechanics with the practical demands of deep-space exploration.
