If all goes according to plan, Chang'e 4's lander-rover duo will touch down within the moon's South Pole?Aitken (SPA) basin after a 27-day flight, then study both the surface and subsurface of this region.
In a study published last month, Yingzhuo Jia, of the University of Chinese Academy of Sciences, and colleagues laid out the mission's chief scientific objectives.
(Jia is also with the State Key Laboratory of Space Weather, National Space Science Center of the Chinese Academy of Sciences.)

The Chang'e 4 lander carries the Landing Camera (LCAM), the Terrain Camera (TCAM), the Low Frequency Spectrometer (LFS), and the Lunar Lander Neutrons and Dosimetry (LND), which was provided by Germany.
