Shanghai's "Gold Medal Rocket" Continuously Excels Self, China's First New Satellite Successfully Launches Four Symbols | Satellite | Shanghai
At 10:50 am today, the Long March 2D carrier rocket successfully launched four satellites, including the Sixiang 01 satellite, into the designated orbit at the Taiyuan Satellite Launch Center, and the launch mission was a complete success.
The Long March 2D carrier rocket, known as the "Gold Medal Rocket", is a room temperature liquid two-stage carrier rocket developed by the Shanghai Institute of Aerospace Technology of China Aerospace Science and Technology Group. It has a takeoff thrust of about 300 tons and a corresponding capacity of 1.3 tons in a 700 kilometer sun synchronous circular orbit. It has the ability to launch single and multiple satellites in different orbit requirements at the three major satellite launch centers of Jiuquan, Taiyuan, and Xichang.
This is the fourth launch mission of the Changerding rocket at the Taiyuan Satellite Launch Center this year, and also the fourth commercial launch mission undertaken this year. The "One Arrow, Four Stars" mission this time, although the number of satellites is not large, includes a stackable flat satellite with a larger envelope size. After receiving the task, the model team carefully studied the size, weight, and other information of the four satellites. In order to provide better environmental conditions for the satellites, they ultimately designed a "series parallel connection" configuration for the fairing cabin.
This mission is the first time that the Chang'er-Ding rocket has adopted a 4-meter diameter fairing, which was formed by the team's adaptive design based on fully drawing on the mature technology of other carrier models in Shanghai Aerospace. A larger diameter fairing can meet a more diverse range of satellite launch needs.
The four satellites launched this time, including Sixiang 01, were respectively developed by Sixiang Aishu and Galaxy Aerospace. Among them, the Galaxy Space Lingxi 03 satellite is a flat stacked satellite configuration, which is the first satellite in China to use flexible solar wings and also the first in orbit verification of multi star stacked launch technology in China. It will provide technical support for the rapid deployment of China's giant low orbit communication constellations.
This launch is the 77th launch of the Long March 2D carrier rocket, the 189th launch of the Long March series carrier rocket developed by Shanghai Aerospace Science and Technology Corporation, and the 479th launch of the Long March series carrier rocket.
