New rocket engines in making for moon, Mars

Chinese engineers are pushing forward with the research and development of engines to be used on the country's next lunar probe and its first Mars probe, a project leader said.

Liu Zhirang, president of the Academy of Aerospace Propulsion Technology in Xi'an, Shaanxi province, said that there will be more than 70 engines categorized within six series on the Chang'e 5.

Liu told China Daily in an exclusive interview that work on the liquid-propellant engines has been proceeding well, though some of the engines are new to Chinese engineers.
