China's space programme started later than those of Russia and the US, but it has made great progress in a short time. China became the third country in the world to independently send humans into space in 2003, when Yang Liwei successfully orbited Earth in the Shenzhou 5 spacecraft. Then Shenzhou 6 and 7 completed a second manned orbit and the first Chinese spacewalk, followed by the vehicle Jade Rabbit being sent to the moon to study its surface. After that, China launched the Tiangong 2 space lab into space and Tianzhou 1 to dock with it. This signalled one step further in China's plan to establish a space station in the future. More recently, China has sent Chang'e 4 to explore the surface of the far side of the moon to make measurements and observations.
