On the 23RD February 2024 Hour Hong- Kong SAR – Beijing time CNSA –China National Space Administration At 19:30 on February 23, 2024, Beijing time, the “Chang Zheng -Long March 5” Yao-7 carrier rocket carrying the communication technology test satellite No. 11 was launched from the 101 station of the Wenchang launch site, Hainan Province, China, People’s Republic of China., sending the satellite into the geosynchronous transfer orbit (GTO).
Communication technology test satellite No. 11 was developed by the Communications and Navigation Department of the Fifth Academy of China Aerospace Science and Technology Corporation. It is mainly used to carry out multi-band, high-speed satellite communication technology verification.


The Chang Zheng -Long March 5″ Yao-7 carrier rocket is a new generation launch vehicle developed by the First Academy of China Aerospace Science and Technology Corporation. It is a large cryogenic liquid bundled launch vehicle. It adopts a two-stage and a half configuration, consisting of a core first stage, a core second stage, and four boosters. device composition. The maximum height of the rocket is about 63.2 meters, with a core diameter of 5 meters and a booster diameter of 3.35 meters. It can be equipped with a standard fairing with a diameter of 5.2 meters and a length of 12.267 meters and an extended fairing with a diameter of 5.2 meters and a length of 18.5 meters. The take-off mass is about 877 tons, with a take-off thrust of about 1,068 tons, and its Geosynchronous Transfer Orbit (GTO) capacity is not less than 14 tons. This rocket is China’s launch vehicle with the highest altitude, the strongest mid-to-high orbit capacity, and the highest carrying efficiency currently in service.

Since its successful first flight, the ” Chang Zheng -Long March 5″ rocket has carried out 7 launch missions, and has achieved 5 consecutive victories since Yaosan. This launch comes only 70 days after the last launch of the “Chang 5″ series rockets, setting a record for the minimum launch interval of the ” Chang Zheng -Long March 5″ series rockets. Starting from the launch of the ” Chang Zheng -Long March 5 Yao 7 Carrier rocket at the end of 2023, the ” Chang Zheng -Long March 5″ series rockets have entered a high-density launch period. Four launch missions are planned in 2024, and five launch missions are expected to be carried out in 2025. In the first half of 2024, the ” Chang Zheng -Long March 5 carrier rocket will carry out the launch mission of the “Chang’e-6” lunar probe of China’s lunar exploration project, and send the “Chang’e-6” to the back of the moon for sample return. This will be the first time in human history , is also the most complex lunar exploration mission in China’s history.

This launch is the first launch of the “Chang 5” rocket in 2024, the second space launch from the Wenchang Launch Site, the 9th launch in China and the 37th launch in the world.
