Long March 9 (Chinese: 长征九号火箭, LM-9 or Changzheng 9, CZ-9) is a Chinese super-heavy carrier rocket that is currently under development. [1] [2] It is the ninth iteration of the Long March rocket family, named for the Chinese Red Army's 1934–35 Long March campaign during the Chinese Civil War.
It will feature a 2-metre (6.6 ft; 79 in) diameter primary mirror and is expected to have a field of view 300–350 times larger than the Hubble Space Telescope. This will allow the telescope to image up to 40 percent of the sky using its 2.5 gigapixel camera over ten years. It will co-orbit with the space station in a slightly different ...

Long March 2 was the original model in the Long March 2 rocket family, which was derived from China's first ICBM, the DF-5. The development work began in 1970. The first rocket was launched on November 5, 1974, [1] but the launch failed. After the failed first launch of Long March 2, its design was slightly modified and designated as Long March 2A.
RS-68 being tested at NASA's Stennis Space Center Viking 5C rocket engine used on Ariane 1 through Ariane 4. A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket.
It could deliver up to 57,000 lbf (250 kN) of thrust with a specific impulse of 279 s (2.74 km/s) or 239 s (2.34 km/s) at sea level. Thrust was variable from 50 to 100 percent , and the restart capability allowed it to be shut down and restarted during flight when necessary.
The RL10 is a liquid-fuel cryogenic rocket engine built in the United States by Aerojet Rocketdyne that burns cryogenic liquid hydrogen and liquid oxygen propellants. Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum.
The Long March 2C (LM-2C), also known as the Chang Zheng 2C (CZ-2C), is a Chinese orbital launch vehicle, part of the Long March 2 rocket family.Developed and manufactured by the China Academy of Launch Vehicle Technology (CALT), [2] the Long March 2C made its first launch on 9 September 1982.
