Long March 9 vs. Long March 5
The Long March 9 was different from the Long March 5 in many aspects: 1. ** Carrying capacity **: - The Long March 9 low-Earth orbit (LEO) had a carrying capacity of 140 tons, the Earth-Moon transfer orbit (LTO) 50 tons, and the Earth-Fire transfer orbit (TMT) 44 tons, while the Long March 5 low-Earth orbit had a carrying capacity of 25 tons and the synchronous transfer orbit 14 tons. It could be seen that the carrying capacity of the Long March 9 in low-Earth orbit, Earth-Moon transfer orbit, and Earth-Fire transfer orbit far exceeded that of the Long March 5. 2. ** size **: - The core of the Long March 9 had a diameter of 10 meters and a height of about 110 meters. The total length of the Long March 5 arrow was 56.97 meters and the diameter was 5 meters. Therefore, the Long March 9 was larger than the Long March 5 in diameter and height. 3. ** Take-off Quality **: - The Long March 9's take-off mass exceeded 4000 tons, while the Long March 5's take-off mass was about 878 tons. The Long March 9's take-off mass was nearly five times that of the Long March 5. 4. ** Mission usage **: - The Long March 9 was developed in response to the needs of future deep space exploration, manned moon landing and fire landing, space infrastructure construction (such as space solar power plants), and other missions. The Long March 5 was mainly used to complete the launch missions of various spacecraft such as low-Earth orbit satellites, Earth-synchronous transfer orbit satellites, Sun-synchronous orbit satellites, space stations, lunar probes, and Mars probes.

Long March 9 2021
On 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. The novel "Hundred Years of Spaceship" is equally exciting.

Long March 11
The Long March 11 had a capacity of 0.7 tons in low-Earth orbit, 0.5 tons in 500-kilometer sun-synchronous orbit, and 0.4 tons in 700-kilometer sun-synchronous orbit. The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!
Long March 9, 2033
The Long March 9 was planned to carry out two flight verification missions around 2033. Its basic model (the first stage of the rocket can be reused, the second/third stage is not reused) is expected to fly for the first time in 2032 - 2033, and the two-stage fully reused configuration is planned to fly for the first time in 2033 - 2035. The Long March 9 will carry out a sub-level fixed-point return test at sea around 2033, and finally break through the key technology of two-stage complete reuse.

Reborn on the Long March
There were a few novels about being reborn on the Red Army's Long March that were worth recommending. Among them," Long March: 1934-1936 " was a detailed description of the classic battles that the China Red Army experienced on the Long March. In addition, the Red Army is not afraid of the difficulties of the expedition, Ballad of the Long March, Morning Sun Flower, and Red Streamer of the Earth were also novels about the Long March. In addition, Dreaming of Sword was also a possible choice. It told the story of the protagonist traveling back to 1927 in his dream, looking for Li Yunlong, and joining the Red Army with the commander. I hope these recommendations will meet your needs.
Long March 9 and SLS
The Long March 9 was a heavy-duty rocket that China was planning, and the SLS was a super-heavy rocket developed by NASA. In terms of capacity, the Long March 9 low-Earth orbit capacity reached 150 tons, and the Earth-Moon transfer orbit capacity was 50 tons. There were three versions of SLS, Block1 low-Earth orbit capacity 95 tons, Earth-Moon transfer orbit capacity 27 tons, Block2 low-Earth orbit capacity 130 tons, Earth-Moon transfer orbit capacity 46 tons, its capacity level was lower than the Long March 9. Moreover, the final design version of the Long March 9 was the bare version that was announced in 2022, and none of the three versions of the SLS chose the recycling plan. However, the Long March 9 was currently in the design stage, and it would take at least seven or eight years before it was actually launched. The SLS had already completed its first flight, so it was more practical. In terms of design concepts, SLS focused more on saving design and production costs. It tried to use ready-made technology and components, such as the engines and solid boosters retained from the space shuttle program. China's Long March 9 had a small historical burden and little task pressure. The design plan was more relaxed and free. It focused on the application of new concepts and chose a recycling plan with multiple engines in parallel. This solution could achieve power redundancy. If calculated according to 20% - 30% power redundancy, a certain number of engines could be allowed to fail at the same time. According to the failure rate of China's existing rocket engines, it could almost guarantee that the Long March 9 would not fail due to engine failure. Moreover, when the engine was reused many times under the recycling plan, the redundancycould effectively increase the number of times the engine was used. In terms of simplicity, the SLS rocket design focused more on simplicity, easy operation, and easy upgrade. The first stage only used four engines in parallel plus two solid boosters (a total of six engines working at the same time), while the Long March 9 used 24 engines and all of them were connected in parallel inside the same rocket launcher. This was a huge challenge for Chinese rocket design because China used to have at most two or three engines in parallel in the same rocket launcher. Multiple engines in parallel were a huge challenge to the rocket control system. In terms of technology, the SLS rocket was not completely new. The STB thruster and the core first-stage engine, the PS- 25 engine, were both from the space shuttle. Solid rocket engines had shortcomings such as difficulty in adjusting thrust, low specific impulse, and difficulty in reducing costs. China's Long March 9 development goal included making up for the aerospace power shortcomings. It was currently developing three "Gods-class" liquid rocket engines. The first-stage engine used the YF130 high-pressure liquid oxygen kerosene engine with a sea level thrust of 500 tons. The specific impulse was about 308 seconds. It had successfully completed its first test run. It was currently the world's largest single-chamber high-pressure liquid oxygen kerosene rocket engine.
