Mission Analysis and Spacecraft Design of Chang’E-7

Abstract

In recent years, international lunar exploration has mainly focused on the south pole of the Moon. Chang’E-7 (CE-7) mission, through the development of orbiter, lander, rover and hopper, will achieve a comprehensive exploration of the lunar south pole including surrounding, landing, moving, and leaping. The harsh lighting conditions, terrain conditions, and temperature conditions at the lunar south pole have brought many challenges to the design of the spacecraft. CE-7 spacecraft has broken through a series of barriers with advanced technologies including high-precision fixed-point soft landing on complex terrain, lunar surface leaping, lunar landing and walking, global perception and mission planning, and fidelity sampling of water ice and volatiles. It has laid a solid technical foundation for the smooth implementation of the mission and the subsequent aerospace cause in our country.
