To facilitate scientific research and science popularization, the Chinese Astronomical Society (CAS) invited experts to translate the Mars terrain terms issued by the International Astronomical Union (IAU) before 15 July 2020 into Chinese. The translations were reviewed and approved by a special committee for astronomical terms affiliated to the CAS and the China National Committee for Terms in Sciences and Technologies.
following the successful launch of China's first Mars exploration mission, CAS released the recommended Chinese names of 811 Mars terrain features on its website. According to this catalogue, Utopia Planitia is translated as: 乌托邦平原
