我国的"嫦娥四号"探测器已经在月球反面度过500个地球日。着陆器和"玉兔二号"月球车在月球反面完毕了冰冷的月夜休眠,迎来第18月昼作业期。 China's Chang'e-4 probe has survived 500 Earth days on the far side of the moon.      The lander and the rover Yutu-2 have resumed work for the 18th 凯时kblunar day on the far side of the moon after "sleeping" during the extremely cold night.    The lander woke up at 3:25 am Sunday (Beijing time), and the rover awoke at 11:53 am Saturday. Both are in normal working order, according to the Lunar Exploration and Space Program Center of the China National Space Administration.    The Chang'e-4 probe, launched on Dec 8, 2018, made the first-ever soft landing on the far side of the moon on Jan 3, 2019.    A lunar day equals 14 days on Earth, and a lunar night is the same length.   The Chang'e-4 probe switches to dormant1 mode during the lunar night due to the lack of solar power.
