  • About author:ZHANG Lihua (1970− ), received his Bachelor’s degree in Mechanical Design and Manufacture from the Beijing Institute of Technology and got his Master’s and Doctor’s degrees in System Design of Spacecraft from the China Academy of Space Technology. He has been working on the development of small spacecraft at DFH Satellite Co., Ltd. He was responsible for the system design of several small satellites involved in different application fields. He is the project manager and chief designer of Queqiao relay communications satellite for the Chang’e 4 lunar far side exploration mission.

Abstract: Queqiao relay communications satellite was developed to provide relay communications services for the lander and the rover on the far side of the moon. From entering into its halo mission orbit around the Earth-moon libration point 2 on June 14, 2018, it has operated on orbit more than fifteen months. It worked very well and provided reliable, continuous relay communications services for the lander and the rover to accomplish the goals of Chang’e 4 lunar far side soft landing and patrol exploration mission. The on-orbit operation status of Queqiao relay communications satellite is summarized in this paper.
