We never see the far side of the Moon. Do you think it looks identical to the near side that we do see?
On October 4, 1959, Russia's Luna 3 was launched towards the Moon, where it later became the first vehicle to send back images of the Moon's far side.
Surprise! The distant hemisphere looked entirely different: Instead of dark lava spots, this side has many craters—scars received during its first few hundred million years of life.
The Dark Side?
There is no continually dark "side" of the Moon. Every part of the Moon has both day and night in half–month intervals.
