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.
On March 4, 2021, the National Space Administration officially released two high-resolution photos of Mars and a medium-resolution color image of the north pole of Mars. The high-resolution camera presented in black and white, showing all the details of the Martian landscape. In the eyes of scientists, these photos are invaluable, not only providing a basis for subsequent Mars landings, but also discovering a lot of new information.
