China’s Chang’e-4 lunar rover made the first-ever soft landing on the far side of the moon

With the Moon’s rotation and orbit keeping it forever in step with the Earth, only one part of it is visible from this planet at any time. The unseen part is the “far side of the Moon”.
Earth’s gravitational pull has brought the Moon’s spin into sync with its orbit.
It takes exactly 28 days for the Moon to complete one rotation, and the same time to make one orbit around Earth. This leads to a phenomenon called “tidal locking”.
