The launching crew training rocket called the Long March 5, China's largest and most powerful rocket, is moved to a launching tower at the Wenchang Satellite Launch Center in south China's Hainan province on Nov.23. This is the first time that the Long March 5 has been completely shown in public. The rocket is made up of four large boosters and a core unit, according to Liu Tongjie, deputy head of lunar exploration and space programs at the State Administration of Science, Technology and Industry for National Defense, which oversees China's space activities.
