Three space tracking ships of China's Yuanwang fleet completed maritime monitoring of the country's first Mars probe launch in the Pacific Ocean Thursday.
A Long March-5 rocket blasted off Thursday from the Wenchang Spacecraft Launch Site in the southern province of Hainan, sending China's Mars probe into the Earth-Mars transfer orbit.
About six minutes after the liftoff, Yuanwang-6 detected and locked its targets, and carried out measuring of the rocket, and control and monitoring of the Mars orbiter.
The other two tracking ships, Yuanwang-5 and Yuanwang-7, then took turns to complete their missions.
The monitoring process lasted nearly 30 minutes.
As scheduled, Yuanwang-5 and Yuanwang-7 will return to China, while Yuanwang-6 will sail to its next mission area for satellite monitoring.
