China is constructing the largest steerable radio telescope in Asia with a 70-m-diameter antenna to receive data from its first Mars exploration mission which is expected to be launched this year. The construction of the telescope began in October 2018 in Wuqing District of northern China's Tianjin and is expected to be completed this year. Many new technologies have been utilized to improve efficiency and reduce interference noises
