Having landed on Mars in mid-May, China's Zhurong rover has successfully completed its primary 90-sol mission. Remaining in excellent condition, it will now continue exploring the Red Planet to uncover more geological insights.
On May 15 at around 4 a.m. Beijing time, the Tianwen-1 probe released its lander and Zhurong rover, navigating the riskiest phase of its 10-month journey. Hours later, they touched down safely in the expansive rocky plain of Utopia Planitia after piercing Mars' atmosphere at over 4 kilometers per second within their entry capsule. This made China the third nation to achieve a successful Mars landing, following Russia and the United States.
Originally planned for 90 Martian sols (roughly 92 Earth days), the mission was officially extended on August 15, as announced by the China National Space Administration (CNSA).
CNSA reports that Zhurong's instruments are performing optimally. Relaying data via the Tianwen-1 orbiter, the rover has transmitted 10 gigabytes of raw scientific information. The focus is on the geology of Utopia Planitia, a site potentially once bordering an ancient ocean billions of years ago.
Zhurong is outfitted with dual cameras for imaging nearby rocks, a multispectral camera, and a laser spectrometer for compositional analysis. Like NASA's Perseverance, it features ground-penetrating radar to probe subsurface geological processes along its path.
Since landing, the rover has covered nearly 890 meters, examining rocks, dunes, and other surface features.
Zhurong and its orbiter will enter safe mode from mid-September to late October due to solar conjunction, when Mars aligns behind the Sun from Earth's view, halting communications. NASA's Curiosity and Perseverance rovers will do the same between October 2 and 14.
Post-conjunction, the Tianwen-1 orbiter will adjust its orbit to conduct a global Mars survey with its instruments while continuing to relay Zhurong's data.
