China's lunar rover Yutu-2 takes second midday nap

Lunar rover Yutu-2 started taking its second midday nap on the far side of the moon on Monday. Without good thermal control, the moon rover, also known as Jade Rabbit-2, had to take a midday nap to avoid overheating, as the midday temperature on the far side of the moon had surpassed 100 degrees Celsius. Yutu-2 and the lander of the Chang'e-4 probe were awakened by sunlight on January 29 and 30, respectively, after a long "sleep" during the first extremely cold night on the moon.
