Man In The Moon Got His Looks From Asteroids

The GRAIL mission is providing new insight into how the moon’s surface got its looks. The so-called “man in the moon” can attribute his looks to asteroid impacts leaving lava-filled impact basins. But what we now know is that both the far and nearside have been impacted but reacted in much different ways. GRAIL maps show that the nearside of the moon has more large impact basins than the far side. Scientists say this is probably because temperatures on the nearside are much hotter with an abundance of heat-producing elements and impacts that occur in hot, think crusts produce basins twice the diameter of similar impacts into a cooler crust.
