Video Caption: The YF-77 rocket engine for the Long March-5 Y4 launch vehicle was tested for 100 seconds on CASC’s rocket engine test facility in Beijing, China, on 19 January 2020. Wang Shuguang, director of engine test, presented the facility and Wang Weibin, deputy chief designer of the Long March-5 rockets, explained the test. YF-77 is China’s first cryogenic rocket engine that burns liquid hydrogen and liquid oxygen as fuel. The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the China’s space program.
In recent weeks, Chinese officials have revealed more details about the investigation into the Long March 5 launch failure last year as well as their ambitious launch plans for this year, which include a landing on the far side of the moon.
Long March 5 will be returned to flight in the second half of 2018, according to Bao Weimin, head of the Science and Technology Committee of the China Aerospace Science and Technology Corporation (CASC). Engineers have identified the cause of a launch failure that occurred last July and are working to verify it, he said.
