From July 23, 2020 to mid-October 2021, for more than 450 days, the "Tianwen-1" probe, which carried out China's first Mars exploration mission, safely passed the "Sun Transit Period", overcoming obstacles along the way. This is the first time that the Chinese have stepped out of the Earth-Moon system to go further into the deep space. In order to explore the mysteries of Mars, several teams of scientists from all over China have joined the ranks of scientific payload development and data analysis.
