Ebb and Flow

Ebb and Flow are the twin NASA spacecrafts that make up the Gravity Recovery And Interior Laboratory (GRAIL) lunar mission.  Ebb has taken a look at the far side of the Moon, the one we never see, and returned this video:

And this is why we never see that side, from CNN:

As for the "far side of the moon," as NASA says on its website, the time it takes the moon to make one rotation on its axis is the same amount of time it takes the moon to orbit around the Earth.

"So," NASA explains, "one 'side' of the moon is always facing the Earth, and the other 'side' is always facing away from the Earth."
