Researchers at the State Key Laboratory of Remote Sensing Science contributed to the Neukum lunar chronology model with data from measuring and analysing Chang'e 5 samples. The scientists measured the radiometric age of the samples and concluded that they are around 2 billion years old. That allows to complement the most widely used chronology model, the Neukum model, established by Gerhard Neukum in the 1980s. Samples from Apollo and Luna missions were mainly older samples, leaving a gap in the age model which could be filled now.
The findings were published in Nature Astronomy.
