People's Daily Online, Beijing, December 27 (Zhao Zhuqing) A reporter learned from the National Space Administration that at 20:45 on December 27, the Long March 5 Yaosan carrier rocket was ignited at the Wenchang space launch site in China. After about 2220 seconds, In practice, the XX satellite was accurately sent into the planned orbit at a distance of 192 kilometers at an apogee and 68,000 kilometers at an apogee, and the launch flight test was successfully completed. This launch flight test mainly assesses the correctness and coordination of the overall plan of the Long March V rocket and its sub-system solutions, and verifies the key technologies related to subsequent space missions.
The Long March V launch vehicle is an upgrade project of China ’s launch vehicle. As China ’s first high-thrust non-toxic and non-polluting liquid rocket, it has many innovation difficulties, large technical span and high complexity. The rocket uses a new 5-meter core-level arrow body structure, bundles four 3.35-meter diameter boosters, a total length of 57 meters, a take-off weight of about 870 tons, a low-earth orbit carrying capacity of 25 tons, and a geosynchronous transfer orbit of 14 tons. The monthly transfer track carrying capacity is 8 tons, and the overall performance and overall technology have reached the international advanced level. The success of this mission means that China has the ability to launch heavier spacecraft or send the spacecraft to deeper deep space. It is important for countries such as the third phase of the future lunar exploration project, the first Mars exploration, and manned space flight. Important foundations and prerequisites for science and technology projects and major projects.
This is the 323th launch of the Long March carrier rocket.
