On July 29, 2021, Beijing time, China’s Long March 2D carrier rocket successfully launched their Tianhui-1 04 satellite from the Jiuquan Satellite Launch Center, which then successfully entered its scheduled orbit, successfully completing the mission. This was the 54th launch of the Long March 2D and 381st flight of the Long March series of carrier rockets.
Tianhui-1 04 was developed by the Aerospace Dongfanghong Satellite Co., Ltd. of the Fifth Academy of China Aerospace Science and Technology Corporation, and is mainly used for scientific experiment research, land and resources survey, map surveying and mapping and other tasks.
In this launch, the Long March 2D carrier rocket used a new, integrated, ground measurement and launch system for the first time in Jiuquan. This system can meet the test and launch requirements of the Long March 2D and Long March 4 series of carrier rockets various technical states. The features of miniaturization, automation and unattended operation effectively simplify the configuration of the ground measurement and transmission system and combine with the continuously optimized measurement and transmission process to improve work efficiency.
The Long March ⅡD carrier rocket is a normal temperature, liquid, two-stage carrier rocket developed by the Eighth Academy of China Aerospace Science and Technology Corporation. The rocket has a take-off thrust of 300 tons and a carrying capacity of 1.2 tons and possesses ingle-satellite and multi-satellite launch capabilities.
