China’s Mars rover might be stuck, but scientists making use of information from the mission are nonetheless hopeful that the automobile can reactivate and discover when a lot more.
Zhurong, which is element of China’s Tianwen 1 Mars mission, landed in Utopia Planitia in May well 2021. The rover entered a dormant mode in May well 2022, successfully enabling it to hibernate for the duration of winter in the planet’s northern hemisphere.
It was supposed to autonomously resume activities in December final year, about the time of Mars’ northern spring equinox, when temperatures and lighting circumstances have been a lot more favorable for the solar-powered automobile. That has not occurred.

Nonetheless, Yi Xu, an associate professor at the Space Science Institute at Macau University of Science and Technologies, told (opens in new tab) VICE Planet News that there might nonetheless be hope for Zhurong.
China has not commented on the status of Zhurong, but photos from NASA’s Mars Reconnaissance Orbiter (MRO) prove the rover has remained stationary for a even though.
The MRO photos show that “it really is covered by the sand and the dust, so it undoubtedly hurts its potential to transform sunlight to electrical energy,” Xu stated.
“We have to wait, due to the fact now it really is spring, and later, that’d be the summer time season on Mars. Then it should really acquire a lot more sunlight and the temperature also increases,” Yi stated. “When the battery is completely charged, then the rover or the instrument might operate once again.”
Zhurong has active implies of cleaning its solar arrays, but its period of inactivity in an region prone to dust storms has apparently impacted its potential to create electrical energy and retain heat. Zhurong does not have a radioisotope heater unit, like other rovers like China’s Yutu moon explorers, but alternatively has a pair of “windows” enabling a chemical known as n-undecane to retailer heat power.
The rover was anticipated to wake up autonomously when two circumstances are met. These are essential elements reaching a temperature of higher than five degrees Fahrenheit (minus 15 degrees Celsius) and power generation of higher than 140 watts.
Xu is a co-author of a current paper that utilized information from Zhurong’s ground-penetrating radar to develop a image of the layers promptly beneath the Martian surface and reveal complicated layering.
Irrespective of whether or not Zhurong rises once again, the mission currently exceeded its planned lifetime of 3 Earth months. The rover has also, like its companion Tianwen 1 orbiter, completed its key science ambitions.
