## China Successfully Launches Zhongxing 4A Satellite, Boosting Communication and Broadcasting Development
**BEIJING, August 22 (Xinhua)** — At 20:25 Beijing time on August 22, China successfully launched the Zhongxing 4A satellite into space from the Wenchang Space Launch Center using the Long March 7A carrier rocket. The satellite successfully entered its designated orbit, marking a complete success for the launch mission.
The Zhongxing 4Asatellite, developed by the Fifth Academy of China Aerospace Science and Technology Corporation (CASC), is a communication and broadcasting satellite that can provide voice, data, and television transmission services to users. The successful launch of this satellite will further enhance China’s communication and broadcasting capabilities, providing strong support for national economic development and social progress.
The Long March 7A carrier rocket, developed by the First Academy of CASC, is a new generation of medium-sized high-orbit liquid carrier rockets in China. For this mission, the rocket used a 4.2-meter diameter fairing basic configuration. This launch marks the 16th launch of the Long March 7 series rockets and the 8th launch of the Long March 7A carrier rocket. On June 29 this year, the Long March 7A carrier rocket also successfully launched the Zhongxing3A satellite from the Wenchang Space Launch Center.
The successful completion of this mission signifies another leap forward in China’s aerospace technology, showcasing the technical prowess of CASC in satellite development and launch. The successful launch of the Zhongxing 4A satellite will inject new vitality into the development of China’s communication and broadcasting industry, providing users with more high-quality and convenient services.
It is understood that the Zhongxing 4A satellite will work in coordination with other in-orbit satellites to build a more comprehensive communication and broadcasting network, providing stronger information security for China’s economic and social development.
**Related Background:**
In recent years, China’s space program has developed rapidly, achieving a series of major breakthroughs. China has become one of the few countries in the world capable of independently developing and launching various types of satellites. The successful launch of the Zhongxing 4A satellite once again demonstrates China’s aerospacetechnological strength and lays a solid foundation for the future development of China’s space program.
**Expert Opinions:**
Experts from CASC stated that the successful launch of the Zhongxing 4A satellite will further enhance China’s communication and broadcasting capabilities, providing strong support for national economic development and social progress. Inthe future, China will continue to strengthen aerospace technological innovation, continuously improve aerospace technological levels, and make greater contributions to human exploration of the universe and the peaceful use of space.
