China's Mars Rover Stalled by Dust on Red Planet

China's Zhurong rover on Mars has been in hibernation since last May due to an "unpredictable accumulation" of dust, according to mission designer Zhang Rongqiao. The rover is expected to automatically wake up when the light and weather conditions improve with temperatures inside the cabin surpassing -15 degrees Celsius and when there is enough sunlight to charge the battery to at least 140 watts. The rover's primary mission was to search for signs of ancient life, and it has so far worked 358 days and traveled 1,921 meters on Mars.
