At 0:30 on July 13th, the huge roar sounded the Xichang Satellite Launch Center surrounded by the mountains. The 03 -star ignition of the Temple of Tianchain was lifted off, and the satellite was precisely sent to the scheduled track, and the launch task was successfully successful.

Tianchang No. 2 is the second -generation Earth synchronous track data relay satellite. The successful launch of Tianchang No. 2 Star has achieved the Samsung Samsung Samsung Global Networking of Tianchain No. 2, and my country's track -oriented relay satellites have also increased to 8. Up to now, the five Sky Chain No. 1 satellites and 3 Sky Chain No. 2 satellites are all launched by the long -distance rockets including the three -way rocket, including the three -year -old rocket, and the launch power is 100%.

The technical status of the three -B -rockets of the task is generally stable. At the same time, the model team has always adhered to the reliability of the arrow in the design and development process and enhanced the safety of ground equipment. Zhang Tao, the overall deputy director of the overall design department of the first hospital, introduced that there are three main technical changes in the rockets of the rocket. The developers optimized the battery heating circuit and time -order tester of the control system and measurement system to further improve reliability.

In recent years, the long -term series of rockets have continued to maintain high density launch. For the current status of the launch venue equipment for a long time and many times, the development team carried out the maintenance work plan for the recovery stage of the launch site. Increase strict inspection items such as cable network signal inspection and ground power inspection to ensure that the ground equipment meets the subsequent launch tasks after the maintenance is completed.

This launch is the 426th launch of the Long March series of launch vehicles.
