A Chinese lunar rover has landed on the far side of the moon, in a global first that boosts Beijing's ambitions to become a space superpower.
The far side of the moon is relatively unexplored and communication is hard because it always points away from Earth and signals could be blocked.
Landing on the far side means that the Moon will separate the spacecraft from Earth, making it impossible for the probe to communicate directly with our planet.
The Chinese probe had been circling the Moon in an elliptical orbit in preparation for landing since Sunday.

Because the far side faces away from Earth, it is also shielded from radio transmissions - making it the flawless place from which to study the universe.
Photo taken by the landform camera on the Chang'e-3 moon lander on December 16, 2013 shows the Yutu moon rover during Chang'e-3 lunar probe mission's first lunar day circle.
Previous spacecraft have seen the far side of the moon but none has landed on it.
No lander or rover has ever touched the surface there, positioning China as the first nation to explore the area.
As a solution, China in May blasted the Queqiao ("Magpie Bridge") satellite into the moon's orbit, positioning it so that it can relay data and commands between the lander and Earth.
During the lunar day, also lasting 14 Earth days, temperatures soar as high as 127 C (261 F).
Adding to the difficulties, Chang'e-4 was sent to the Aitken Basin in the lunar south pole region - known for its craggy and complex terrain - state media has said.
It would also like to develop a moon base through several manned missions.
