小天体智能附着技术研究进展

To meet the robust landing requirement in the exploration and exploitation of small celestial bodies，based on the landing exploration missions in China and abroad，the requirements of intelligent landing technologies were analyzed and the corresponding research progress was discussed. Firstly，the landing exploration missions for small celestial bodies were reviewed. Then，the traditional rigid landing mode and the novel intelligent flexible landing concept of small celestial bodies were introduced，and the intelligent technology requirements of small celestial body landing were sorted out. On this basis，the research progress on intelligent landing technologies was summarized from the aspects of dynamics，mission planning，perception，navigation，guidance and control. Finally，the development trend of landing technology of small celestial bodies is envisioned.
