China debuted the new medium-lift Long March 7 launch vehicle on Saturday from its new Wenchang Space Launch Center. It was the first launch from the new coastal spaceport.
The new booster carried a scaled-down version of a next-generation space vehicle designed to carry Chinese astronauts into Earth orbit and deep space. The spacecraft is set to land autonomously in Inner Mongolia after orbiting the Earth.
The two-stage Long March 7 is capable of launching 13,500 kg (29,800 lb) in low Earth orbit and 5,500 kg (12,100 lb) into sun synchronous orbit. The stages are powered by liquid oxygen and kerosene, which are cleaner than the hypergolic fuels that power older Long March boosters.
The new rocket is designed to replace the Long March 2 and Long March 3 boosters. The first stage is based on the Long March 2F rocket that is used to launch cosmonauts into space aboard Shenzhou spacecraft. The new booster shares engines with the Long March 5 and Long March 6 rockets.
