China’s Yuanwang-class tracking ships will assist the launch, along with support from the European Space Agency’s ESTRACK facilities. First acquisition of the spacecraft as it separates from its Long March 5 launcher is expected to be made by the 15-meter antenna in Kourou, French Guiana. Deep space antennas in Australia and Spain will also track the Tianwen-1 spacecraft during critical activities like trajectory-change maneuvers and arrival at Mars.
