The Long March 9 (LM-9 or Changzheng 9, CZ-9, Chinese: 长征九号) is a Chinese super-heavy carrier rocket concept proposed in 2018 [3] that is currently in study. It is planned for a maximum payload capacity of 140,000 kg [4] to low Earth orbit (LEO), 50,000 kg to trans-lunar injection or 44,000 kg to Mars.[5][6] Its first flight is expected in 2030 in preparation for a lunar landing sometime in the 2030s;[7] a sample return mission from Mars has been proposed as first major mission.[6] It has been stated that around 70% of the hardware and components needed for a test flight are currently undergoing testing, with the first engine test to occur by the end of 2018. The proposed design would be a three-staged rocket, with the initial core having a diameter of 10 meters and use a cluster of four engines. Multiple variants of the rocket have been proposed, CZ-9 being the largest with four liquid-fuel boosters with the aforementioned LEO payload capacity of 140,000 kg, CZ-9A having just two boosters and a LEO payload capacity of 100,000 kg, and finally CZ-9B having just the core stage and a LEO payload capacity of 50,000 kg.[8] Approved in 2021, the Long March 9 is classified as a super heavy-lift launch vehicle.[7]
