It was China’s first independent mission to Mars, and made the country only the second, after the United States, to successfully place a rover on the planet.’s 10 — a list of ten people who helped to shape science in 2021.
As the programme’s chief designer, I am responsible for engineering development, spacecraft launch and flight control. Once the mission was in flight, I had to keep track of the spacecraft’s status, find the right people to deal with emergencies and ensure that the probe remained in good working condition, so that our rover could successfully land on Mars and achieve its objectives.
