Tianwen I is China’s first Mars probe（火星探测器）. Where does the name come from? Do you still remember Qu Yuan, a famous poet in ancient China? He loved his motherland very much. His long poem “Heavenly Questions（天问）” expresses the continual hard work and the great spirit of the Chinese nation to science. That is why Tianwen I was officially named, which is quite cultural and beautiful.
On July 14, 2020. Tianwen I arrived at the Wenchang Space Launch Site（发射站）in Hainan Province. The space probe Tianwen I based off（发射升空）at 12:41 p.m. on July 23, 2020, carrying a Long March 5 carrier rocket（长征5号运载火箭）. It took Tianwen I about seven months to travel to Mars.
The China’s Mars rover（火星车）, Zhurong moved from is landing platform（平台）onto the surface of the Red Planet at 10:40 a.m. on May 15th, 2021, starting is exploration（探险旅程）around the landing site.
The 240-kilogram robot was sent into the sky to survey Mars’ landforms, geography situation, and something about water, ice, environment and other physical fields.
Before Tianwen I, no country had ever tried to send an orbiter（运行器）, a lander and a rover in one single expedition（考察）to Mars.
