After "sleeping" through long lunar night, solar-powered Chang’e-4 probe independently switches back to working mode on Friday morning as sun returns, CCTV reported.

The moon rover Yutu-2 had also woken up earlier on February 28 and is functioning normally too.

China's Chang'e-4 probe, launched on December 8, 2018, landed on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on January 3, 2019. 

A lunar day equals 14 days on Earth, and a lunar night is the same length. The radioisotope heat source, a collaboration between Chinese and Russian scientists, will support the probe through the lunar night when the temperature falls.
