中国明朝官员万户据说是世界上第一个“宇航员”。他坐在绑着火箭的椅子上,试图把自己发射到外太空。月球背面的环形山“万户”就是以他的名字命名的。

On 23 July 2020, China’s first Mars lander, Tianwen-1, was sent into space from Wenchang, Hainan Island. The spacecraft takes its name from an ancient poem by Qu Yuan(340–278 BCE ). “Tianwen” means “Questions to Heaven” and expresses China’s determination to explore the universe.
Mars has interested people for thousands of years. Around 3,000 years ago, in ancient China, people already knew about the planet and began to study how it moved in the sky. However, it was difficult to find out more about it before the 20th century.Thanks to the work of scientists, we have learnt a lot about Mars. Spacecraft like Tianwen-1 will help us find out more about our red neighbour.

Exploring Mars
After travelling more than 470 million kilometres, Tianwen-1 reached the red planet on 10 February 2021. The craft circled around the planet for three months before landing on the surface on 15 May. There, it released a 240-kilogram rover named Zhurong.
During the next 100 days, Zhurong drove 1,000 metres on the planet’s surface and continued its travel. It took photos of Mars and studied different kinds of rocks, and then it sent the information back to the Earth.
The success of Tianwen-1 is only the beginning of China’s Mars exploration programme. Maybe one day Chinese astronauts will visit Mars.
