Design of the Payload Subsystem of Chang’E-5 Lunar Explorer

To achieve the scientific and engineering goals for situ exploration of the sampling area, The payload subsystem of Chang'E-5 explorer is equipped with four types of scientific payloads: the panoramic camera, descending camera, lunar regolith penetrating radar, lunar mineral spectrometer. It is also equipped with the national flag of China exhibition system, the panoramic camera pan-tilt table, and payload data processor as engineering and supporting payloads. This paper introduces the scientific and engineering goals, system composition, function and performance, system design, and operating achievements of the Chang'E-5 payload subsystem.
