The main content of the report is as follows: Professor Quan first introduced the asteroid anchoring plan based on cross-drilling geometric force closure of ultrasonic drill, and reported the key technical research results of ultrasonic drill, including the development of ultrasonic drilling and anchoring principle prototype and ground test verification. Subsequently, the retractable claw-type anchoring scheme was introduced, including the development and ground experimental verification of the principle prototype. Finally, the two schemes were compared and analyzed.
