The Chang'E-4 lunar explorer is composed of a communication relay satellite, a lander and a rover. The latter two are the backup of Chang'E-3. It is estimated that the Chang'E-4 explorer will be launched by the end of 2018,which is scheduled to land at the South Pole Aitken (SPA) basin, and carry out in-situ detection and reconnaissance at the farside of the moon with the communication support of the relay satellite. Chang'E-4 mission has been planned to install six scientific payloads to complete the corresponding tasks. Three payloads are installed on the lander,including the Landing Camera (LCAM),the Terrain Camera (TCAM), and the Low Frequency Spectrometer (LFS); and the other three payloads are installed on the rover, including the Panoramic Camera (PCAM), the Lunar Penetrating Radar (LPR), and the Visible and Near-Infrared Imaging Spectrometer (VNIS). The LFS is newly developed for Chang'E-4 lander,and the other five payloads are inherited instruments from Chang'E-3. Besides the above six payloads, there are also three international joint collaboration payloads to be installed on Chang'E-4 explorer, which are the Lunar Lander Neutrons and Dosimetry (LND) on the lander, the Advanced Small Analyzer for Neutrals (ASAN) on the rover, and Netherlands-China Low-Frequency Explorer (NCLE) on the relay satellite. In this paper, the scientific objectives,landing area overview, payload configurations and system designs, and the task for each payload with its main technology index of Chang'E-4 mission are mainly discussed. |
