The dark side of the Moon remained a mystery until space travel allowed for circumnavigation. What did the astronauts find?
- The Moon orbits around the Earth and spins on its axis.
- These rotations both take 28 days, so the same side of the Moon always faces Earth.
- The side of the moon that we don't see is commonly known as the 'dark side of the Moon'.
- In 1968, astronauts were sent to view the dark side of the moon for the first time.

This is called synchronous rotation.
Because of this synchronicity, the same side of the Moon always faces the Earth.
The other side of the Moon – the side which we ...
