Formation age of the Rima Sharp sinuous rill on the Moon, source of the returned Chang’e-5 samples
DOIAbstract
Context. In December 2020, China’s Chang’e-5 spacecraft successfully returned 1731 g of lunar samples to Earth. Rima Sharp, one of the longest sinuous rilles on the Moon, lies very near (<20 km) to the Chang’e-5 sampling site and is very likely to be the source of the returned samples. Constraining its formation age would provide key references for the ongoing sample analyses. Aims. Our intent is to obtain the accurate formation ages of Rima Sharp and related lunar rilles through crater population studies and to assess their implications for the Chang’e-5 sample analyses and interpretations. Methods. We utilized two separate techniques to measure and analyze craters that were formed after the formation of the studied sinuous rilles: the con...
