我国的"嫦娥四号"探测器已经在月球背面度过500个地球日。着陆器和"玉兔二号"月球车在月球背面结束了寒冷的月夜休眠，迎来第18月昼工作期。

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 lunar 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.
