On May 15,Zhang Rongqiao wiped tears from his eyes as China's Mars rover (巡视器) Zhurong landed safely on Mars. "I was so excited," said Zhang.
As the chief designer (总设计师) of China's Tianwen Ⅰ Mars mission (任务),Zhang was chosen by the journal Nature on Dec 16 as one of the top 10 people "who helped shape science" in 2021.Under Zhang,China made a huge step in interplanetary (行星向的) exploration. "I got a taste of the old Chinese saying ﹣ it takes 10 years to sharpen a good sword," Zhang told Nature.
In the Mars mission,Zhang led a team of thousands of researchers.The team was not only responsible for technical work like launches and flight control,but also for scientific research on Mars.
There were many difficulties.They knew little about the strange and complex environment of Mars. "We may not even know what we do not know about," Zhang told Nature.
During the process,Zhang played a key part in the decision to send an orbiter (轨道飞行器),a lander (着陆器) and a rover to Mars together in one shipment (运输) ﹣ making China the first country to do so. "That's a big leap (飞跃) because China is doing in a single go (what NASA took decades (数十年) to do)," said Roberto Orosei from the Institute of Radioastronomy of Bologna in Italy.
Zhang also made the important decision to land the rover on Utopia Planitia,where there are special landforms (地形) for scientists to study.He hopes that the mission can do as much research as possible and bring back "rich" information.
"The buck stops with him (他敢作敢当)," said David Flannery,an astrobiologist (天体生物学家) at Queensland University of Technology in Australia.
a.Launching the rover.
b.Controlling the flight.
c.Bringing back space junk.
d.Doing scientific research.
