Цитата: Цитата 7 June 2017China prepares first manned mission to the moon
Yang Liwei, deputy director general of China Manned Space Agency and China's first man in space, said it will “not take long” for the manned mission to the moon to get official approval and funding, state news agency Xinhua said late on Tuesday.
The report gave no other details, but such a trip could still be many years off.
A government official said last year that China wants to put astronauts on the moon by 2036, in what state media said was the country's first confirmation of a manned lunar exploration programme.
Цитата: Цитата March 27, 2018Long March 9 will fly to the Moon in the 2030s
The Long March 9 rocket should be a three-stage rocket equipped with two to four powder boosters. A prototype engine to equip the first floor of the rocket is about to be built. This first floor will burn kerosene and liquid oxygen, like the Saturn 5. The second and third floors of the Chinese launcher will be powered by hydrogen.
China wants to make the first flight of the Long March 9 in 2028, and wants to make a first manned flight to the moon in the 2030s. Between 2028 and 2033, three launchers would be able to equal or exceed the performance of the Saturn 5 : the NASA’s SLS capable of placing 130 tons in low orbit, the Long March 9 capable of placing 140 tons, and the SpaceX BFR capable of placing 150 tons in low orbit. Even if it is not sure that the three rockets will fly, at least one of them could make us relive the immoderation of the Apollo years.

The Long March 9 will be a Saturn 5-class super-heavy-lift rocket comparable in capacity to the Space Launch System currently being developed under NASA.
According to Long, the Long March 9 will be capable of lifting 140 metric tons to low Earth orbit, 50 tons to Earth-Moon transfer orbit, and 44 tons to Earth-Mars transfer orbit.
The 93-meter-high Long March 9 is expected to have a launch mass of over 4,000 metric tons, producing close to 6,000 tons of thrust.
The core stage will have a diameter of 10 meters while four boosters will each have a diameter of up to 5 meters. This would make the boosters comparable to the Long March 5, China’s largest rocket so far, which debuted in 2016 and last July suffered a first stage engine issue that prompted a redesign. A third flight of the rocket is expected around November.
The Long March 9 is slated to be ready for a test flight around 2030, with Long adding that progress on the project includes successful forging of 10-meter-diameter alloy rings and breakthroughs related to 500-ton-thrust kerosene-liquid oxygen and 220-ton-thrust hydrolox engines.
