The absolute model age (AMA), or geologic age of Finsen crater on the moon’s far side is determined to be about 3.5 billion years (Ga) based on crater counting method, according to a study published in Icarus.
The study was conducted by a research team led by Prof. Di Kaichang from the State Key Laboratory of Remote Sensing Sciences, Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS).
Based on this model age, the regolith growth rate at the Chang’e-4 landing site and the crater degradation rate within Finsen crater have also been estimated.
China’s Chang’e-4 probe, including a lander and a rover, successfully touched down the floor of Von Kármán crater within the South Pole-Aitken (SPA) bas...
