The name Tian Wen No.1 comes from Tian Wen, a long poem written by Qu Yuan, a famous patriotic poet in China. This poem depicts natural phenomena such as the separation of heaven and earth, the change of yin and yang, the sun, the moon and the stars, and expresses the author's brave exploration spirit of pursuing truth. Therefore, this series of Mars exploration missions was named Tian Wen, which is also to carry forward the great spirit of the Chinese nation's courage to explore, pursue truth and dare to innovate, and has a very beautiful meaning.

China Mars probe is a Mars probe developed by China. It aims to explore the form, soil, environment and atmosphere of Mars, and study the distribution, physical field and internal structure of water and ice on Mars. China's first Mars exploration mission should not only realize the global remote sensing exploration around Mars, but also break through the key technologies of Mars entry, descent, landing, patrol, long-distance measurement and control communication, and truly enter deep space and get close to Mars.
