In situ lunar phase curves measured by Chang'E-4 in the Von Karman Crater, South Pole-Aitken basin
Context. The Yutu-2 rover of the Chang'E-4 (CE-4) mission measured the lunar phase curves in the Von Karman crater, South Pole-Aitken basin. Aims. We aim to study the photometric properties of the regolith at CE-4's landing site and compare them with those of Chang'E-3 (CE-3) in order...

The CE-4 site may have experienced more space weathering alterations than the CE-3 site, which is consistent with their different surface model ages (similar to 3.6 Ga for CE-4 and similar to 3 Ga for CE-3).
