Management of science, technology and industry for national defense of China explained the failure to start in July last year of the carrier rocket of China «Changzheng-5» problem in the engine of the first stage.

The launch, which was supposed to deliver to orbit a communications satellite «Lizzani-18», was carried out from the Baikonur Wenchang (Hainan province) 2 July last year. The start was the second for this type of missiles and failed.

As they say in the message published in the account of the Corporation, aerospace science and technology of China (CASC) in the mobile app WeChat, experts, based on computer simulations and ground tests, found that the mission failed due to a problem with the nozzle of the turbine first-stage engine.

It is noted that after checks, the first stage engine of the carrier rocket «Changzheng-5», which will be used for the third start, was refined and tested extensively.

The third launch was to take place in late November of last year. It was planned that the rocket will deliver to the moon probe «Chang’e-5», which was supposed to land on the moon, collect lunar soil samples and return to Earth.

According to the latest data, the third start-up «Changzheng-5» is scheduled for the end of this year. As previously reported by Chinese media, if the start is successful, this will be the impetus for the preparation of a new manned missions, launch module of the Chinese space station in 2019, as well as the launch of the lunar probe «Chang’e-5».

The project on development of «Changzheng-5» was approved by the state Council of China in 2006. As fuel for «Changzheng-5» uses liquid oxygen and liquid hydrogen.
