Today is the first anniversary of tianwen-1's landing on Mars. On May 15, 2021, tianwen-1 successfully landed in the south of the Utopia plain of Mars, leaving a Chinese mark on Mars for the first time. So far, it has worked on the surface of Mars for 356 Mars days, with a total mileage of 1921 meters. The orbiter has flown for 661 days since its launch. Since entering the annular fire orbit, it has continued to carry out remote sensing detection.
At present, the two devices are in good condition, and the accumulated original scientific data is about 940gb. The team of scientists is carrying out data analysis, interpretation and research. Now let's describe the work course of tianwen-1 in one year through a long picture.
At present, the inspection area of the "zhurong" rover has entered winter. The maximum temperature during the day has fallen below minus 20 ℃, the minimum temperature at night has fallen below minus 100 ℃, and dust weather is frequent. Affected by the gradual reduction of solar irradiation angle and local dust weather, the energy acquisition capacity of the "zhurong" Rover gradually decreases and the heat preservation consumption gradually increases. In order to cope with this harsh environment, according to the design scheme, the rover will be switched to winter mode. The orbiter continues to carry out remote sensing exploration, is about to achieve global coverage of Mars, and provides relay communication support for the rover.

As the first mission of China's planetary exploration project, tianwen-1 has realized the leap of China's space exploration from Earth Moon system to interplanetary system, and completed the orbit, landing and patrol exploration of Mars for the first time in the world. It is another milestone in the development of China's aerospace industry.
