Thanks to CTOnews.com netizens and monks for their clue delivery! CTOnews.com, January 9, according to the news of the China Aerospace Science and Technology Group, 06:00 on January 9, China used the long March 7 modified carrier rocket at the Wenchang Space launch site. The satellite Shishi 23 and the test satellite 22 A / B were successfully launched, the satellite entered the scheduled orbit smoothly, and the launch mission was a complete success, representing a good start for China's space flight in 2023.

Shi 23 satellite was developed by the eighth Academy of China Aerospace Science and Technology Group Co., Ltd., and is mainly used to carry out scientific experiments and technical verification. Test 22 A / B satellite is mainly used for on-orbit verification test of new technologies such as space environment monitoring.

The Chang 7A rocket, developed by the first Institute of China Aerospace Science and Technology Corporation, is a new generation of medium-sized high-orbit liquid carrier rocket in China, with a geosynchronous transfer orbit carrying capacity of up to 7 tons. it fills the gap in the carrying capacity of China's carrier rockets from 5.5 tons to 7 tons in high orbit.

China Aerospace Science and Technology Corporation said that the Shiji 23 satellite launched this time is the heaviest satellite ever launched by a medium-sized high-orbit carrier rocket in China. In order to meet the needs of the load, the Chang 7A rocket team adopted the basic configuration of the 4.2-meter diameter fairing and developed a star-arrow interface with a larger diameter.

In order to adapt to the trend of further increase in satellite weight in the future, the Chang 7A rocket team will also develop an improved rocket capable of adapting to the 5.2 meter diameter fairing by replacing the third stage, so as to further enhance the comprehensive performance of the Chang 7A rocket.

CTOnews.com learned that this launch is the 459th launch of the long March series of carrier rockets.
