The moon rover and lander of China's Chang'e 3 lunar probe mission will "sleep" during the lunar night, enduring extreme low temperatures on the lunar surface.
China's moon rover, Yutu (Jade Rabbit), completed an arm flexing assessment early on Monday, a key test before beginning other work on the surface, according to the Beijing Aerospace Control Center.
