Mons Rümker is a large volcanic complex in northern Oceanus Procellarum on the Moon and has high scientific and exploration value. A research group led by Jiannan Zhao mapped this region as a candidate site for China’s first lunar sample return mission, Chang’E-5. They identified 22 volcanic domes and proposed two landing site candidates: one located on top of a young volcanic dome, and the other within the oldest surface unit of the plateau. Samples from these sites will help elucidate the duration of volcanic activities and the composition of the plateau, constrain the age of large impact events on the Moon, and improve methodologies for determining planetary surface ages.
