China has successfully tested a new engine for its Long March 9 super-heavy launch vehicle, which is set to play a key role in lunar exploration and deep space missions.

According to the South China Morning Post, Chinese scientists have managed to overcome technical difficulties in creating a prototype of the YF-79 rocket engine, which is intended for the third stage of the rocket.

The 25-ton YF-79 is a hydrogen-oxygen engine with an expansion thrust cycle. The first stage of the Long March 9 with boosters will be powered by four YF-130 oxygen-kerosene engines with an additional combustion cycle. For the second stage of the rocket, a pair of YF-90 hydrogen-oxygen engines is provided. New YF-79 engines are developed for the third stage, there are four in total.

It is expected that the Long March 9 will be able to launch up to 140 tons of payload into low Earth orbit, from 15 to 50 tons to the Moon, from 12 to 44 tons to Mars.
