BEIJING, May 15 (Xinhua) -- It has been a year since China's Tianwen-1 probe landed Mars. The mission has not only marked an important step in the country's interplanetary exploration but has also made a number of achievements in that time.
The Tianwen-1 probe consists of an orbiter, a lander and a rover. On May 15, 2021, it touched down at its pre-selected landing area in Utopia Planitia, a vast Martian plain, marking the first time that China has landed a probe on the planet.
A week later on May 22, 2021, the Mars rover Zhurong, which resembles a butterfly, drove down from its landing platform to the Martian surface. On June 11, the China National Space Administration released the first photographs taken by Zhurong, signifying a complete success in the country's first Mars exploration mission.
Since landing, Zhurong has continued moving southward and transmitted data back to Earth. It has completed explorations of the Martian surface, passed through multiple complex terrains, and detected Martian rocks, sand dunes and impact craters, obtaining a large amount of data using its onboard scientific equipment.
By Aug. 15, 2021, Zhurong had worked on the planet's surface for 90 Martian days, or about three months on Earth, accomplishing all exploration and detection tasks as planned. It was in good condition and continued service despite reaching its planned working target of 90 days.
