China's Long March-5B carrier rocket arrived at the Wenchang Space Launch Center in Hainan province on Wednesday after a week of ocean and rail transport.
With a liftoff weight of 849 tons, the rocket will take part in a joint rehearsal with the prototype of the Chinese space station's core module.
It is scheduled to make its maiden flight and launch the prototype of China's new manned spaceship in April.
The rocket has the largest carrying capacity in low-Earth orbit among all Chinese rockets.
