The Chinese Deep Space Network is a network of large antennas and communication facilities that supports the lunar and interplanetary spacecraft missions of China. It is managed by the China Satellite Launch and Tracking Control General (CLTC).^[1]^[2]

The network was first needed for the lunar mission Chang'e 1,^[3]^[4] but will be used to support future missions to the moon and Mars. Similar networks are run by the USA, Russia, European countries, Japan, and India.
