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.

What does the title “Space: The Final Frontier” mean to you Share your ideas with the whole class.
While I support space exploration, I don’t think space is the final frontier just yet. There is still much to learn about the Earth, and we are only at the very beginning of new technological breakthroughs involving information technology and AI. There are many scientific and technological frontiers all around us.
