scheduled to soft land on  Von Kármán crater on 3 Jan, 2019 Von Kármán will offer the chance to analyse the variations of composition of the lunar surface and SPA melt sheet with the Visible and Near-Infrared Imaging Spectrometer ( VNIS ), while also returning unprecedented images with cameras on both the lander and rover. A number of subsequent impact craters in the surrounding region, such as Finsen, are expected to have delivered ejecta to the floor of Von Kármán, potentially providing a rich sample of the SPA basin and far side geologic history. The Lunar Penetrating Radar (LPR) and low‐frequency radio spectrometer (LFS) payloads will also return unique data from the landing region, while the Lunar Lander Neutrons and Dosimetry ( LND ) instrument and Advanced Small Analyser for Neutrals ( ASAN ) will provide insight into the space environment and interactions with the surface. The CNSA administration said Chang’e 4’s scientific tasks included astrono...
