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. On 23 July 2020, China sent Tianwen 1 to explore the surface of Mars. It arrived in February 2021 and then sent back lots of valuable information. And from 2021 to 2022, China completed a number of rocket missions to establish its own space station.In 2022, the launch of the Mengtian module signalled the basic completion of the Tiangong Space Station. This modern space station will allow astronauts to conduct
many important experiments, greatly furthering our understanding of the universe.
