Could the history of the founding of China be described in the form of a novel introduction?In the novel," Zhen Fa ", at the end of the Yu Dynasty, heroes rose up together. The islands in the East Sea elected the Wu family as the emperor, the rich lands in the south were stolen by the Yang family, the land of the three rivers in the west was occupied by the Liu family, the capital area became the possession of the Cao family, the northern land was unified by the Shi family, the grassland was unified by the Chengyun tribe, and the barbarians in the far west established the Saro Empire. This was a true history of the founding of the country. If this was described like a novel introduction, it could be described as follows: The seven major powers rose up during the turbulent period of the deposed dynasty and established their own countries. The world was divided into seven parts, and war raged everywhere. The people's lives lost their fundamental security. The history of this period was tragic and hot-blooded, showing the brave and unyielding spirit of the Chinese people.
China's most advanced rocket is the Long MarchThe Long March 9 was currently a very advanced rocket. The latest design of the Long March 9 would be established at the end of 2024 and was expected to achieve its first flight in 2032. It had a diameter of 10.6 meters and a height of 110 meters, and it did not require a propeller. However, the evaluation criteria for " advanced " might involve many aspects, such as carrying capacity, technological innovation, etc. The other rockets of the Long March series also had their own unique advantages and advancements. For example, the Long March 12 launch vehicle successfully flew for the first time on the evening of November 30,2024. It was developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It was the first in the Long March series to have a 4-meter arrow body diameter, achieving a large diameter and large thrust, which was conducive to the high performance of the rocket. It could also adapt to the fairing of different diameter structures according to the mission requirements, supporting single-star and multi-star launch in different orbits, and opening up new technologies, industries, and models for commercial rockets in China. A new chapter in the development of a new industry.

Long March 9 2021On June 24,2021, Academician Long Lehao, an aerospace expert, announced the latest version of Long March 9 at a speech in Hong Kong. The Long March 9 "2021 version"(referred to as the "21 version") was larger than the "11 version" core class, with greater thrust and carrying capacity. It could meet the needs of large-scale manned flights in the future. The biggest difference between the "21 version" and the "11 version" was the removal of the thrusters. This change was to reduce its weight while increasing its carrying capacity. "Version 21" Long March 9 replaced the four YF - 130 engines with a single thrust of 480 tons with 16 YF - 135 liquid oxygen kerosene engines with a single thrust of 350 tons. This not only made the thrust nearly 6000 tons, but also reduced the weight of the thrusters by 15 tons. The design height of the "21 edition" Long March 9 was 108 meters, the diameter of the first and second cores increased from 9.5 meters to 10.6 meters, and the diameter of the fairing increased to 9.5 meters. Its main engine was 16 YF - 135 high-pressure liquid oxygen kerosene engines that were being planned. The thrust of a single chamber was 360 tons, 120 tons higher than that of the YF - 130. Although the "21 version" and "11 version" had a take-off thrust of about 5800 tons, the "21 version" had a greater thrust in the second and third stages. The second stage used four 120-ton 120tHo hydrogen oxygen engines, which increased the thrust by 40 tons. The third stage used a 120-ton 120tHo hydrogen oxygen engine, which increased the thrust by 20 tons. The 21st version of Long March 9 saved the dry weight of four 15-ton boosters, increasing the carrying capacity to 150 tons.
