Astronomy and Space
The Chinese Deep Space Network (CDSN) is a network of large antennas and communication facilities that are used for radio astronomy, radar observations, and spacecraft missions of China. The CDSN is managed by the China Satellite Launch and Tracking Control Center General (CLTC) of the People's Liberation Army Aerospace Force. The network was first needed for the lunar mission Chang'e 1, and since has been used to support subsequent missions to the Moon and Mars such as Chang'e 5, Tianwen-1, and Tianwen-2 missions. Similar deep space networks are run by the United States, Russia, European countries, Japan, and India.
