About

Xiaoming Lai is a leading figure in extraterrestrial robotics, whose work has been pivotal to China’s lunar exploration ambitions. His primary research focuses on the mechanics of planetary regolith and the design of autonomous sampling systems for space missions. Lai’s most significant contribution is his central role in developing the robotic drill for the historic Chang’E 5 mission. As detailed in his highly cited 2023 paper, this 2-meter class drill successfully penetrated one meter into the lunar surface in December 2020, collecting and returning 259.72 grams of precious samples—the first such retrieval in over 40 years. His foundational 2019 review on regolith-sampling robots has garnered 79 citations, establishing a benchmark for the field. Further, his 2021 study on lunar regolith compressibility and its effect on thick wall spiral drills provides critical insights that directly informed the successful coring system used on the Moon. With over 110 combined citations for his key works, Lai’s research bridges fundamental soil mechanics and cutting-edge robotic engineering, directly enabling one of the most celebrated achievements in modern space science.
