A Chinese rocket launch failed on Sunday evening due to abnormality during the flight following what appeared to be a successful liftoff, the official Xinhua News Agency said.
Experts will investigate the cause of the glitch for the launch of the Long March-5 Y2, China's second heavy-lift carrier rocket, from the Wenchang Space Launch Center in the southern province of Hainan, Xinhua said.
