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.
