China’s Mars rover may well be stuck, but scientists employing information from the mission are nonetheless hopeful that the car can reactivate and discover as soon as much more.

Zhurong, which is element of China’s Tianwen 1 Mars mission, landed in Utopia Planitia in May possibly 2021. The rover entered a dormant mode in May possibly 2022, properly permitting 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 situations had been much more favorable for the solar-powered car. That has not occurred.

Even so, 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 may well nonetheless be hope for Zhurong.

China has not commented on the status of Zhurong, but pictures from NASA’s Mars Reconnaissance Orbiter (MRO) prove the rover has remained stationary for a whilst. 

The MRO pictures show that “it really is covered by the sand and the dust, so it certainly hurts its potential to transform sunlight to electrical energy,” Xu stated. 

“We have to wait, mainly because now it really is spring, and later, that’d be the summer time season on Mars. Then it must acquire much more sunlight and the temperature also increases,” Yi stated. “When the battery is totally charged, then the rover or the instrument may well operate once more.”

Zhurong has active implies of cleaning its solar arrays, but its period of inactivity in an location prone to dust storms has apparently impacted its potential to produce electrical energy and retain heat. Zhurong does not have a radioisotope heater unit, like other rovers which includes China’s Yutu moon explorers, but rather has a pair of “windows” permitting a chemical known as n-undecane to retailer heat power.

The rover was anticipated to wake up autonomously when two situations are met. These are crucial 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 utilised information from Zhurong’s ground-penetrating radar to construct a image of the layers promptly under the Martian surface and reveal complicated layering.

Irrespective of whether or not Zhurong rises once more, the mission currently exceeded its planned lifetime of 3 Earth months. The rover has also, like its companion Tianwen 1 orbiter, completed its principal science objectives.
