On the 0813 30th December 2023 Saturday Hours Hong- Kong SAR – Beijing time CNSA –China National Space Administration , China, People’s Republic of China. Successfully launched the Chang Zheng- Long March 2C/Yuanzheng 1S Jiuquan Satellite Launch Center, Inner Mongolia, China, People’s Republic of China, and then successfully launched a new advance satellite internet technology.
The Long March 2C/Yuanzheng 1S carrier rocket ignited and took off at the Jiuquan Satellite Launch Center, and then successfully sent the satellite Internet technology test satellite into the predetermined orbit. This year, all 48 space missions of the launch vehicles developed by China Aerospace Science and Technology Corporation were a complete success. The satellite Internet technology test satellite was developed by the Fifth Academy of China Aerospace Science and Technology Corporation.
“Long March 2C” is a medium-sized two-stage room-temperature liquid launch vehicle developed by the First Academy of China Aerospace Science and Technology Corporation. Its main power uses dinitrogen tetroxide/uniform dimethylhydrazine (N2O4/UDMH) propellant. The arrow is about 42.3 meters long, with a first and second stage diameter of 3.35 meters, a take-off mass of 241 tons, and a take-off thrust of about 302 tons. Its low-Earth orbit transport capacity is 4 tons, and the maximum transport capacity in the 500-kilometer sun-synchronous orbit is 2 tons. When paired with the “expedition” In the “No. 1 S” upper stage state, the 700-kilometer sun-synchronous orbit has a transport capacity of 2.5 tons…
The “Yuanzheng-1″ commercial/”Yuanzheng-1S” (YZ-1S) upper stage was developed by the First Academy of Aerospace Science and Technology and was improved on the basis of the “Yuanzheng-1” upper stage. The upper stage has a diameter of 2.8 meters, is equipped with a YF-50D engine, uses dinitrogen tetroxide/uniform dimethyl hydrazine propellant, has 2 ignition capabilities, a vacuum thrust of about 0.66 tons, and a vacuum specific impulse of about 316 seconds. This upper stage is mainly aimed at short-term flight missions. It has system optimization and equipment streamlining based on the “Yuanzheng-1” upper stage. Its weight and cost are greatly reduced, and its working time is shorter. After being separated from the basic stage, it can immediately The ignition was accelerated and the entire flight mission was completed within one hour.
Since its successful first flight, the “Yuanzheng-1” commercial upper stage has carried out a total of 7 launch missions, all of which were carried out in conjunction with the “Chang 2-C” rocket. The “Chang 2C” rocket, paired with the “Yuanzheng-1S” upper stage, can perform various orbital launch missions such as low-Earth orbit, sun-synchronous orbit, geosynchronous transfer orbit, and earth-moon transfer orbit, and has the ability to launch multiple satellites in different orbits.
This launch is the 9th launch of the “Long March 2C” rocket in 2023, the 36th launch of the Jiuquan Satellite Launch Center, the 67th launch of China, and the 220th launch of the world. At the same time, this launch is also the final battle between China’s aerospace industry and the world’s aerospace industry this year. The total number of China’s space launches this year reached a record-breaking 67, and the total number of world space launches reached a new high of 220.
This mission is the 505th flight of the Long March series of launch vehicles.
