Chang'e 4 finds moon's far side a frigid affair

China's Chang'e 4 probe, having successfully accomplished the first-ever landing on the moon's far side, found that overnight temperatures on the lunar surface not visible from Earth can fall to as low as - 190 C.

This is the first time Chinese scientists have received firsthand data about nightly temperatures on the far side's surface.

The rover and lander of the Chang'e 4 probe were "awakened" by sunlight after a long "sleep" after their first extremely cold night on the moon, the China National Space Administration announced on Thursday.
